Check the connection and network light: Check whether the connection between the video recorder and the wireless cable is normal, and whether the network light is blinking normally; Check whether the connection between the camera and the wireless cable is normal, and whether the network light is blinking normally. 2. Checking the activation of the fluorite cloud: - For the video recorder, check whether the fluorite cloud is enabled. The path is: Main menu-System configuration-Network configuration-Platform access/External network access. If the video recorder does not support the fluorite cloud before, it will be supported after the upgrade. When the fluorite cloud is enabled, you need to set a Captcha and follow the instructions. - For the camera, check if the fluorite cloud is enabled by the webpage access camera. Path configuration-network-advanced configuration-platform access (Note that the webpage access camera requires the computer IP and the device IP to be in the same network segment. Enter the camera IP address in the Internet Explorer's website bar to access it. If the camera IP address is unknown, you can search through the computer's SAMP software). 3. Checking the network parameters: - For the video recorder, go to the main menu-System configuration-Network configuration-Basic configuration. If you want to enable automatic acquisition of the IP address, you can uncheck it and manually set the network parameters, including: "For the IP address (cannot conflict with other devices), the intranet mask, the gateway, and the Domain Name Server, fill in the IP address assigned by the operator. If you are not sure how to fill in the address, you can try any of the three addresses: 114.114.114.114, 223.6.6.6, and 223.5.5.5. If you have manually set the network parameters, you can tick the automatically obtained IP address and automatically obtain the IP address. - For the camera, path configuration, network, basic configuration, and IP. If you want to enable automatic acquisition of the IP address, you can uncheck it and manually set the network parameters, including: The IP address (cannot conflict with other devices), the mask, gateway, and the same as the IP address for the IP address server. The IP address for the IP address server should be the IP address assigned by the operator. If you are not sure how to fill it in, you can try any of the three addresses: 114.114.114.114, 223.6.6.6, and 223.5.5.5. If the network parameters are manually set, you can check the automatic acquisition of the IP address and automatically obtain the IP address. 4. Testing Equipment Network: - Video recorder test: Enter the main menu-System maintenance-Network detection-Network detection, and fill in the address to be tested in the destination address; fill in the gateway of the gateway (that is, the gateway address) to test whether the local area network is connected. If it prompts "Network unreachable", it means that the network is not connected, which means that the connection between the gateway and the recorder cannot be connected normally. Check the network parameters configuration, whether the connection is normal, check the settings of the gateway, whether to set up IP address filtering or IP address filtering; If it says "Average delay XXms, packet loss 0%", then the local area network is connected, and you can test whether the external network is connected. To test whether the external network is connected, you can fill in dev.ys7.com to test. If it says "Network unreachable", then the network is not connected, which means that the recorder is not connected to the external network. You can change the Domain Name Server. If the prompt "Average delay XXms, packet loss 0%" is displayed, then the external network is connected. In this case, confirm the video recorder version. If it is not the latest version, upgrade to the latest version for testing (note that there are risks in upgrading, and the video recorder cannot be powered off during the upgrade process). - If the camera is still not online, you can try switching to a different IP address. For the configuration of the local area network parameters, you can go to the "configuration"-"network configuration"-"basic configuration" option. It is recommended to cancel the automatic acquisition of the IP address and manually fix the IP address of the video recorder to the same network segment as the route. The IP address of the server should be the IP address assigned by the operator. If you don't know how to fill it in, you can try any of the three addresses: 114.114.114.114, 223.6.6.6, and 223.5.5.5. Activate the fluorite cloud, enter the configuration, network configuration, and fluorite configuration. Activate the fluorite cloud, check if the connection is online, and click apply. 5. When you use Internet Explorer to access IP Cameras for the first time, you must install the plug-in. Plug-in installation method: Enter the IP address of the IP Camera in the address bar of the browser (Internet Explorer). For example, the device address: 192.168.1.160.

What are the external parameters of the camera?
The external parameters of the camera were the parameters in the world coordinate system, such as the camera's position, rotation direction, and so on. In terms of specific values, there were six external parameters of the camera, including the rotation parameters of the three axes (<anno data-annotation-id ="00000000 - 4110 - 4445 - 9999 - 9999 - 9999999999999"></anno>,<anno data-annotation-id ="2f0000c8 - 4f08 - 4f10 - 4f08 - 8f001111100000"></anno>). Combining the 3×3 rotation matrices of each axis (first matrix multiplication) to obtain R (size 3×3) that gathered the information of the three rotation axes, as well as the translation parameters of the three axes of T (Ti, Ty, Tz). R and T were combined into a 3×4 matrix, which was the key to converting to the coordinates of the label paper. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Mobile phone camera with external lens
There were many types of lenses for mobile photography, with different functions. 1. Type 1. ** macro lens **: Able to take close-up shots of objects, suitable for shooting flowers, insects, water droplets, jewelry, fingerprints, jewelry, logo, and other small objects. It can clearly show the details of the microscopic world. 2. ** Telephoto lens ** - A fixed-focus telephoto lens, such as a 400mm fixed-focus lens, could let the phone experience the telephoto effect. When used to shoot scenery, the picture was clear and layered. When shooting characters, the edge of the depth of field was better optimized, the zooming was smooth, and the video effect was also good. There was also a 58mm telephoto lens like the Moment V2. Its internal lens structure could improve the shooting effect and avoid problems such as image shake and distortion when the phone directly pulled the telephoto lens. - A zoom telephoto lens, such as the 22 - 82mm effective focal length of the Tianli MML38 Tianli Sharp Eye zoom macro lens, could meet the needs of shooting at different distances. Second, choose the key points 1. ** Material **: Glass lenses are superior to synthetic plastic lenses in terms of light transmission and color reproduction. Glass lenses are recommended. 2. ** Workmanship **: The craftsmanship of the mirror body, the regularity of the edges, and the clarity of the printed parameters can all be used as a standard to measure the quality of the workmanship. A lens with fine workmanship is usually of better quality. 3. ** Price **: The market price ranges from tens of yuan to hundreds of yuan. Generally, the quality of a lens that costs hundreds of yuan may be better than a lens that costs tens of yuan, but it is not recommended to buy an expensive one. 4. ** Connection Method ** - Magnetic absorption type is not recommended because the magnetic force will become weaker if used for a long time. - The clamp-fixed type was convenient to assemble and disassemble, so it could be considered. - There was also the connection method of the phone's case and lens. 5. ** Exclusive and Universal Version ** - The dedicated version was compatible with the lens of a particular phone. The general version was slightly less stable, but it was more stable as long as it did not shake violently. 6. ** Condition of coating **: The lens with coating can reduce light reflection and increase light transmission. High-quality lenses can also ensure that there are no dark corners and better distortion control. In addition, there was also a wide-angle and macro two-in-one lens, which was cost-effective and suitable for photography enthusiasts. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Calculating the internal and external parameters of the camera
The internal parameters of the camera included: 1. ** Picture format, size, and quality **: There are two types of photo format: RAW and JPG. You can choose JPG format if you don't need post-processing. If you need post-editing, you can choose RAW format. The daily shooting size can be set to large size, and the picture quality can be set to high quality. However, the size can be adjusted to M or S when shooting news topics and other situations that require fast production. 2. ** White Balance **: Automatic White Balance (AWB) can basically meet the needs of daily shooting. In special scenes or when you want to change the image effect, you can manually control it, such as using the built-in scene mode, manually adjusting the K value, etc. 3. ** Light sensitivity (USB)**: For daily shooting, you can set it to the "STAR"(Automatic Light sensitivity). When you use the manual gear (M), you can manually adjust it to control the image exposure. 4. ** Picture Style **: The camera has a variety of photo styles. It is recommended to choose the "standard" style for daily shooting unless you have special needs or want to try other styles. 5. ** Metering Mode **: Including evaluation measuring (Nikon Matrix Metering, Sony-called Multi-Metering), spot measuring, partial measuring, center-emphasized measuring, etc. The most commonly used is evaluation measuring. 6. ** Focus Mode **: For daily shooting, you usually choose AF-S + single-point autofocus. When shooting moving objects, you choose AF-C + extended focus. 7. ** exposure compensation **: In aperture priority/shutter priority mode, it is usually set to "0EV", but it has to be adjusted according to the "white plus black minus" rule. The external parameters of the camera may involve some indicators related to the camera hardware, such as the sensor (which is the heart of the digital camera), as well as lens-related parameters, but the reference did not mention the lens-related external parameters in detail. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The relationship between the internal and external parameters of the camera
The internal parameters of the camera mainly included light sensitivity (USB), shutter speed, aperture, AF-ON, depth of field button, M-GN, image confirmation, lens aberration correction, high USB noise reduction, unequipped memory card release shutter, gridline, white balance, color temperature, saturation, etc. These internal parameters affected each other and were also related to external parameters such as the external shooting environment of the camera. The higher the sensitivity value, the brighter the picture, but the higher the value, the lower the quality of the picture and the more noise. The higher the shutter speed, the less light entering, and the lower the brightness of the picture. On the contrary, the higher the light entering, the brighter the picture. However, the shutter speed should not be too low when shooting high-speed moving objects to avoid blurring the picture. The larger the aperture value, the smaller the aperture, the deeper the depth of field, the less light entering, and the darker the picture. On the contrary, the lighter the depth of field, the more light entering, the brighter the picture. AF-ON can be set to switch between single-shot focus, autofocus, and servo-autofocus, which affects the focus mode. The depth of field button can be set to the photo style to choose portrait or landscape shooting. M-GN can be set to drive mode, focus mode, white balance, and light measurement mode. After clicking M-mn, the settings can be switched. Image confirmation can set the time the photo stays on the camera, which is convenient to check the effect of the photo. The sensitivity can be adjusted by setting the minimum and maximum values; the peripheral brightness correction, distortion correction, digital lens optimization and other operations in the lens aberration correction affect the dark angle and distortion of the picture; the high Iso noise reduction can adjust the brightness of the picture in dark environments; the setting of releasing the shutter when the memory card is not installed is related to whether the shutter can be pressed when the memory card is not installed; the grid line can be used as the reference line for composition; The white balance color temperature affected the color of the screen. If it was less than 5200, it would be cold, and if it was greater than 5200, it would be warm. The saturation affected the color of the screen. The external parameters, such as the light intensity of the shooting environment, would affect the settings of the internal parameters. When the light is dim, you may need to increase the sensitivity, reduce the shutter speed, and increase the aperture to ensure enough light. When shooting external situations such as high-speed moving objects (such as sports events), the shutter speed needs to be set higher. When shooting different subjects such as people or scenery (external parameters), you can use the depth of field button to set the photo style to better shoot. Internal parameters such as white balance and saturation needed to be adjusted accordingly to achieve the ideal color effect under different shooting scenes (external parameters). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Self-made camera with external power supply
Here are some ways to connect your camera to an external power source: - ** For the MDV - 35 digital camera **: - You can buy a 4X1.5V battery pack and install it on the side of the camera with a small screw. It should be noted that the original camera used 2.4 - 3V of electricity, and after installing the battery, it was 4.8 - 6V. This method could solve the problem of power consumption of the camera without damaging the camera. However, the camera's fixing screw design was hidden, so it was difficult to open the case. Pay attention to the hidden screws under the screen cover rubber plug, the black strip on the front of the camera, and the black cover of the camera. - ** For Nikon and Canon cameras (Take self-made universal external power supply as an example)**: - ** Material preparation **: - **18650 battery **: It is recommended to buy Japanese and Korean disassembled batteries, such as Sanyo's "Dahongpao", because the domestic 18650 battery may have the problem of poor battery life, poor durability, and serious false standard. It should be noted that the 18650 battery with a capacity of more than 3500 mAh may be a fake battery. - ** battery box **: Choose a battery box with over and under-voltage protection and USB output that can be used as a power bank. If the disassembled battery had a capacity of 2550 milliamperes and four 18650 batteries were connected in two series and two parallel, the capacity could reach more than 5100 milliamperes. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Access the camera in the docker container
To allow Docker containers to access the camera, you can add parameters. One way is to use the-privileged argument so that the Docker container can use the host's existing devices, including the camera. Another way is to use the--device argument to specify which devices the Docker container can use. For example, if you want the Docker container to be able to use the host's camera, you can use the following command: docker run -it --device=/Dev/video0. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
