Smart camera selection
The following aspects could be considered when selecting a smart camera: 1. ** resolution and resolution **: High-resolution and high-resolution cameras can provide clearer images, which can help improve the accuracy of detection and identification. 2. ** Type of lens **: The lens is an important part of the camera and will affect the clarity and depth of field of the image. 3. ** Wavelength-length, zooming or not **: If the zooming ratio needs to be changed during the imaging process, a zooming lens can be used; otherwise, a fixed-focus lens is enough. As for the working wave length of the lens, it was necessary to consider whether it was a single color light or a multi-color light, whether it needed to be filtered, and whether it could avoid the influence of stray light. The common one was the visible light band, but there were also other band applications. 4. ** Special requirements **: According to the actual application, specify the special requirements, such as whether there is a measuring function, whether a monocentric lens is needed, whether the imaging depth of field is large, etc. 5. ** Working distance, focal length **: These two factors often need to be considered together. Generally, the system resolution can be determined first, and then the magnifying power can be determined by combining the size of the CCD-based image. Then, the distance between the object and the image can be determined according to the spatial structure constraints, and thus the focal length of the lens can be estimated. 6. ** Image size and image quality **: The image size of the selected lens should be compatible with the size of the camera's sensitive surface. The principle of "big is compatible with small" should be followed. The image quality should mainly focus on MTF and distortion. Distortion should be paid more attention to in measurement applications. 7. Aperture and Interface: The lens aperture mainly affects the brightness of the image, but the final image brightness is determined by the aperture, camera gain, integration time, light source, and many other factors. The lens interface needed to match the camera. If it couldn't match directly, consider transferring. 8. ** Interface and communication protocol **: Choose a camera with a suitable interface and communication protocol to facilitate integration with the control system. For the vision camera, if you want to establish an enterprise level communication connection between it and the PC, you need to confirm that it supports network protocol such as swift, ftp, dhmp, DNS, IP client server, Telnet, etc. If you want to connect the vision camera to automated devices such as plcs, robots, etc., you need to choose a camera that supports industrial protocol such as EtherNet/IP, Modbus/ip, etc., and if there is a need to manage and control visual behavior through the network, you also need to confirm whether the camera allows it. 9. ** environmental and climate adaptability **: Choose the camera according to the application environment to ensure that the camera can work normally in harsh environmental conditions. 10. Brand and Quality: A well-known brand and a camera of reliable quality can ensure better technical support and after-sales service. 11. ** Do you need anti-shake ability **: If your hands shake easily when you hold the camera, you can consider a camera with anti-shake ability. You can test the anti-shake ability simply by the degree of trembling when you press the camera. The greater the shaking, the stronger the anti-shake ability. 12. ** Can it be easy to build an application and generate a user graphic interface? **: When the system is deployed, the machine vision camera should be allowed to generate a user graphic interface without the need to develop it with a high-level language such as Visual Basic, so that the operator can adjust the camera, modify the tolerance parameters, and determine the fault point of the part when the part changes. 13. ** Reading and Checking Performance **: If there is a need to read the numerical code of the parts on the production line or verify the data of the medicine bottle, when evaluating the reading and inspection performance, you can pay attention to whether there is a feature such as the training of the statistics font (a model or reference image can be generated from a series of images to cope with the change in the quality of the printed matter), the image pre-processing tool (the trained model is optimized to improve the reliability and repetitiveness of the camera), and the instantaneous image playback (so that the operator and technicians can quickly see the fault image). 14. ** Repeatable measurement tool **: If the application is size, make sure that the measurement tool is not only accurate but also has good repetitiveness.

Requirements for camera selection
The selection requirements of the camera included the following aspects: the clarity and resolution of the camera, the focal length of the lens, the size of the CCD-shaped target, and the resolution. We can come to the following conclusion: 1. Clarity and resolution: The clarity and image resolution of the camera are important considerations when choosing a camera. Generally speaking, the horizontal resolution of the camera should be greater than 500 lines. The higher the resolution, the better the performance of the camera. 2. Focus of the lens: Choose the lens with the appropriate focal length according to the scope and size of the scene that needs to be monitored. Fixed focus lenses were available in 2.8mm, 3.6mm, 4mm, 6mm, 8mm, 12mm, 16mm, 25mm, etc., while zoom lenses could be adjusted manually or manually. 3. The size of the CCD-target: The size of the CCD-target of the camera determines the choice of the lens. When the size of the CCD-target is 1/3 inch, a 1/3 inch lens should be selected; when the size of the CCD-target is 1/4 inch, a 1/4 inch lens should be selected. 4. Pieces: The camera's resolution determined the clarity of the image. Generally, home surveillance cameras choose 1 million, 1.3 million, or 2 million high-definition graphics, and surveillance cameras with a resolution of 720P, 960P, or 1080P can meet most of the needs. In summary, the selection requirements of the camera included factors such as clarity and resolution, focal length of the lens, size of the CCD-shaped target, and resolution.
Smart camera tutorial
The following are some tutorial on how to use smart cameras: ##1. Gold AI camera 1. ** Usage * - He opened the Golden AI camera APP and connected the camera device. - Choose the appropriate shooting mode in the APP, such as portrait, landscape, night scene, etc. - He aimed the camera at the subject and clicked the photo button to take a picture. - After the shooting was completed, he could view the results of the shooting in the app. He could also edit and share it. 2. ** Shooting mode features ** - ** Portrait Shooting **: In portrait mode, the camera will automatically identify the subject and perform intelligent optimization based on the skin color, hairstyle, clothing, and other characteristics of the subject. If the subject was a woman, the camera would automatically adjust the beauty effect to make the skin smoother and more delicate. If the subject was a man, the camera would automatically adjust the sharpness and contrast to make the picture more three-dimensional. At the same time, the camera had a Face Recognition function that could automatically focus and track the subject to ensure that the person was clear. - ** Landscape Shooting **: In landscape mode, the camera will automatically recognize the scene and perform intelligent optimization based on lighting, color, composition, and other factors. For example, when the scene was backlit, the camera would automatically adjust the exposure parameters to prevent over-exposure or under-exposure. In high-contrast scenes, the camera would automatically adjust the HVR effect to make the picture more balanced. It also had a depth-of-field prediction function that could automatically adjust the aperture size according to the distance of the subject to achieve the effect of background blurring. ##2. Smart Cameras (Take cell phones as an example) 1. ** Light sensitivity setting (some phones)** - The sensitivity was the sensitivity of the camera's light sensitivity system to light. The higher the sensitivity, the brighter the picture, but the noise would also increase, so the daily sensitivity should be as low as possible. Some phones could be manually set up to enter the professional camera mode of the phone and adjust it by looking for the "USB" button. Some phones would automatically adjust the sensitivity value according to the shooting environment. 2. ** Use of exposure compensation ** - This was a function to adjust the brightness of the screen. In the camera mode of most mobile phones, the brightness of the screen could be adjusted by clicking the focal point and moving it up and down. The screen darkened when moving down, and the screen brightened when moving up. 3. ** Using the HPR function ** - HVR referred to high dynamic lighting rendering. When the contrast between the light and dark of the scene was strong, there might be problems with overexposed highlights or underexposed shadows. At this time, using the HPR function, the highlights and shadows of the photo could be shot with sufficient detail. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The latest machine vision camera selection
The selection of a machine vision camera requires consideration of the following aspects: ** 1. Type of camera ** 1. ** Line Array Industrial Cameras ** - It was suitable for capturing continuous, long production lines. For example, detecting problems on the roller, or scenes that required a large field of view or extremely high precision. It worked with an extremely long and narrow imaging feature, and the field of view was a slender strip. 2. ** Array camera ** - It was more suitable for capturing the entire scene. 3. **3D camera ** - It is suitable for specific scenarios that require 3D information acquisition. For example, in the 3D machine vision camera market research, it will involve the market size (production capacity, output, sales, output value, price, cost, profit, etc.) and industry competition analysis (raw materials, market applications, product types, market demand, market supply, downstream market analysis, supply chain analysis, major companies, market share, M & A, expansion, etc.). ** 2. Signal Type ** 1. ** Simulation camera ** - An image acquisition card was required. The resolution of a standard simulated camera was very low, usually 768 x 576, and the frame rate was fixed (25 frames per second). The data collected was an analogy signal, which was converted into a digital signal by the digital acquisition card for transmission and storage. However, it is susceptible to distortion caused by electromagnetic noise interference from other equipment in the factory (such as electric motor or high-voltage cable). As the noise level increases, its dynamic range (the ratio of the original signal to noise) will decrease, affecting the amount of information transmitted to the computer. 2. ** Digital camera ** - What was collected was a digital signal that was not affected by electromagnetic noise. The dynamic range was higher, and it could transmit more accurate signals to the computer. ** 3. Determination ** The resolution of the camera was chosen according to the system's requirements. For example, to detect the scratches on the surface of an object, the size of the object required to be shot was 10mm × 8mm, and the required detection accuracy was 0.01mm. Assuming that the field of view to be shot was 12mm × 10mm, then the camera that should be chosen had a minimum resolution of (12/0.01)×(10/0.01) = 1200x1000, which was about 1.2 million pixels. Generally, the lowest resolution camera required was determined according to the actual accuracy inspection requirements. The common camera had 1.3 million resolution to choose from. ** 4. Chip Type ** 1. ** Charge Coupled Device (CCD-Chip) camera ** - If the object to be shot is moving and the object to be processed is also moving in real-time, it is more suitable to choose a camera with a CCD-chip. 2. ** Complimentary Metal Oxide Silicon (LCD) chip camera ** - If the object being photographed was moving very slowly, the distance of the object's movement was very small within the set exposure time of the camera, which was converted to a 1 - 2-pixel-sized image, then the use of a LCD camera was also suitable (if not for measurement). Moreover, if the manufacturer's LCD camera used the frame exposure method, it could also be used as a CCD. However, if the deviation was more than 2 px (caused by the movement of the object), the image taken by the object would have smear, so it was not suitable to choose a LCD camera. ** 5. Other Key Elements ** The frame rate, color depth, dynamic range, and sensitivity of the camera were key factors in the selection. The quality of the lens, the optical format of the camera, the number of graphics, and the type of interface (such as USB, ether, or GigE) were also considerations that could not be ignored when selecting the camera. At the same time, for the line array industrial camera, parameters such as line frequency, line height, and trigger method also needed to be considered. The line frequency was the camera's shooting speed, and the line height was based on the application requirements to determine how many lines to capture an image (that is, the image's "high" resolution). The trigger methods were line trigger (suitable for scenes where the motion speed was not uniform or required some special imaging technology, such as long and short exposure HVR, time-sharing stroboscopic, etc.) and frame trigger (suitable for shooting objects with relatively uniform motion. After the frame trigger, the line array camera would continue to shoot at the set line frequency until it reached the specified line height). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Smart phone camera instructions
Here are the instructions for the smartphone camera: ** 1. Basic Shooting Points ** 1. ** Avoiding the zooming function (if zooming is required)** - If you want to take a picture of a scene or portrait, try to get close to the camera instead of using the phone's zoom function. Because the resolution of the phone's zoom was far inferior to that of an ordinary camera, the picture was easy to blur when using the zoom, and the greater the zoom, the blurrier it became. However, if you used zooming to shoot, you could choose the focal length set in the camera system to shoot on the camera interface of some mobile phones (such as the Huawei P30). The image quality would be better than manually sliding to other focal lengths. 2. ** Make sure the lighting is good ** - The lighting requirements for cell phone shots were high. Due to the simplicity of cell phone photos, it was necessary to choose the appropriate lighting for the shooting scene. Enough brightness was a necessary condition for taking good photos. 3. ** Keep the phone stable ** - The camera on the phone was small and was sensitive to shaking hands. The slight vibration of the phone when the shutter was pressed would blur the image. Therefore, when shooting, try to keep the phone stable. It was especially important in low light because the camera shutter speed was slow, and instability could easily lead to blurring. If possible, place your phone or hand on a stationary object (such as a tree, stone, wall, etc.) to ensure stability. In addition, there was usually a delay of about one second when shooting with a mobile phone. After pressing the shooting button, do not move the mobile phone immediately. You must maintain the shooting posture until the shooting is completed. 4. ** Points to note when taking portraits ** - The camera should be level with the subject, especially when taking pictures of children. Squat down to the height of the child, so that they can make full use of their eyes and smiles. In addition, when taking a portrait, you can turn off the sound of the phone to capture a natural and vivid photo to prevent the subject from being nervous and restrained. 5. ** Clean the lens ** - During the filming process, you should always check the lens for fingerprints or dirt, and wipe it with a tissue or other cleaning items in time. ** 2. Different shooting modes and functions ** 1. ** Photograph/Picture Mode (Common Function)** - ** Focus and Photometering **: Tapping the viewfinder will cause a small yellow frame (focus frame) and a small sun symbol (exposure can be adjusted) to appear. After selecting the focus point, he could slide his finger up and down the screen to adjust the exposure and change the brightness of the photo. Pressing the screen for more than 3 seconds usually locks the focus/exposure, which is very useful when shooting close-ups or spots. - ** Flash **: It is used when there is insufficient light. Normally, it can be turned off. - ** HPR **: It is recommended to turn on automatic mode to capture more details in the light and dark areas in the backlit scene. 2. ** Portrait Mode ** - It could be used to enhance the skin, blur the background, and add different light effects. Take the iPhone as an example. After taking a photo in portrait mode, click edit, then click the f value in the upper left corner to adjust the degree of background blurring (the background becomes more and more blurred when you slide to the left, and the background becomes clearer when you slide to the right). The first option at the bottom can also choose various photography effects. 3. ** Night View Mode ** - It was specially used for shooting night scenes, which could make the exposure and color of the night scene better. 4. ** Professional mode (different parameters and functions)** - ** Metering methods **: Generally, there are matrix dimming (comprehensive dimming of the entire picture), center-focused dimming (focused dimming of the center area of the picture), and spot dimming (for the selected spot dimming, such as when shooting a pure black background with only the main body left). - ** Iso-sensitivity **: It is used to measure the sensitivity of the lens to light. The lower the value, the better the image quality, but the picture was dark. The higher the value, the worse the image quality, and the more noise, but the picture was bright. In the case of poor lighting, the USB can be appropriately increased. When shooting night scenes, the USB is recommended to be between 400 - 800. If you want to shoot night scenes with strong lighting effects (such as traffic and fireworks), you can set it to about 100. At the same time, you can use the phone holder for a long exposure to ensure clear image quality. - **S (Shutter Speed)**: You can control the brightness of the photo. If the shutter speed was slow, the image would be brighter if the light was more, and if the shutter speed was fast, the image would be darker if the light was less. When shooting fast-moving objects, adjust the shutter speed to 1/1000 seconds and above to freeze the moment. If you want to shoot light painting effects (such as light painting, traffic flow, star track, trickle, etc.), you can slow down the S adjustment to 30 seconds. It is recommended to use a stand to maintain stability. - ** RV (exposure compensation)**: You can adjust the brightness of the screen. When the environment is dark, you can increase the RV value. When the light is strong, you can reduce the RV value. - ** AF-Focus Mode **: There are AF-S (single autofocus, suitable for shooting still objects), AF-C (continuous autofocus, suitable for shooting moving objects), and TF (manual focus, self-selected area focus). Generally, autofocus is used. ** 3. Operation examples of specific phones (Huawei phones)** 1. ** camera settings ** - He turned on the camera, clicked on More, and then clicked on the high resolution mode. Then, he clicked on the settings option and changed the video resolution to 4K and the video frame rate to 60 frames, which would make the photos and videos clearer. - The camera that came with the Huawei phone had seven shooting modes. From left to right, there was a large aperture (which could produce a blurring effect), a night scene, a portrait, a photo, a video, a professional, and more. On the top of the shooting interface, there were intelligent vision (you can ignore it), AI photography (you can turn it off normally), flash (usually off), color mode (usually set to the Lycra standard, avoid choosing bright or soft mode to avoid color distortion), settings, and other functions. - On the camera interface of the Huawei camera, click on the yellow focus box on the screen. The yellow sun button on the right side of the focus box is the exposure compensation function. Press and hold to increase the image exposure or decrease the image exposure. ** 4. Function related to photo post-processing (Take the iPhone as an example)** - You can add a text description to the photo. After opening the photo, you can click edit and select the text to add. You can also set the text style, bubbles, and color. - After taking a photo with the original Apple camera in portrait mode, click edit, then click the f value in the upper left corner to adjust the degree of background blurring, and click the first option at the bottom to choose the light effect. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

What format is a smart camera?
There were many image format in smart cameras, and the more common one was the Bayer format. It was one of the main technologies to capture color images with a CCD-based or CMOS-based sensor. It was widely used in modern digital cameras, video cameras, and mobile phone cameras for digital image storage. In addition, some smart cameras also support the raw image format, which contains data directly obtained from the camera's sensor. The image data has not been processed, and the user has more post-processing space. For example, Apple's iPhone has the ProRAW format, and Samsung has Android's Expert RAW photo file format. Some Android 5.0 systems can also support the output of photos in the Raw format. Of course, there were also smart cameras that used JPG and PVP format, but these two format were based on the rendering of raw data. JPG images had already been interpreted by the camera software, including a large number of in-camera processing and automatic modification of the image format. The same was true for PVP format. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
