Other industrial cameras
In addition to the above-mentioned area array cameras, line array industrial cameras, PDA industrial cameras, and wide-format industrial cameras, there were many other types. In terms of sensor types, there were industrial cameras with CCD-type and CMOS-type sensors. Among them, CMOS-type image sensors had gradually become mainstream. CMOS-type sensor cameras with global shutters were more suitable for capturing dynamic images, and CMOS-type cameras with rolling shutters for capturing still images could be considered. From the interface type, it was an industrial camera with a USB 3.0 interface. However, although its transmission speed was fast, the transmission distance was limited. It was not recommended to use it when it was more than 5 meters. Color cameras were used for detection targets that required color recognition. If color recognition was not needed, black-and-white cameras were more cost-effective. Different types of industrial cameras are suitable for different industrial inspection scenarios. When selecting, factors such as resolution, sensor type, interface, color, etc. should be considered to meet specific requirements such as detection accuracy, field of view, and data transmission distance. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The performance characteristics of industrial cameras
Industrial cameras have the following performance characteristics: 1. ** In terms of accuracy ** - It emphasized precision and speed, and had the characteristics of high precision. The size of the picture element was generally 3 - 10 um, and the resolution and the depth of the picture element determined the size of the image together. Increasing the depth of the picture element could enhance the measurement accuracy, but it would reduce the speed of the system and increase the difficulty of system integration. The common depth of the picture element was 8-bit, 10-bit, 12-bit, etc. - It had a high frame rate and resolution, and could capture a large number of images in a short period of time. The resolution generally corresponded to the number of picture elements arranged on the target surface of the sensor, such as 1920*1080. - High-performance industrial cameras had a high signal-to-noise ratio, which meant that the ratio of signal to noise in the image was high, which meant that the image quality was good. The higher the signal-to-noise ratio, the better the camera performance and image quality. 2. ** In terms of stability and reliability ** - The design focuses on stability and reliability, and can adapt to harsh industrial environments. It usually uses a sturdy body and protective shell that can withstand vibration, shock, and temperature changes to maintain stable performance in long-term operation. - It has industrial-grade connections such as GigE Vision, USB3 Vision, or Camera-Link to ensure reliable data transmission. - It has a durable outer shell and internal components that can withstand harsh industrial environmental conditions such as vibration, dust, and temperature changes. 3. ** Function ** - It has flexibility and can be customized to meet different application needs, including the settings of exposure time, gain, white balance and other parameters. - It had an external trigger function to facilitate synchronization with other machine vision equipment. For example, industrial line array cameras could choose fixed line frequency and external trigger synchronization. Area array cameras generally also provided external trigger capture functions. - The exposure time, brightness, gain, and other parameters could be controlled through computer programming, and the image window could be infinitely zoomed. 4. ** In terms of imaging characteristics ** - Its spectral response range was generally 350mn-1000mn. Some cameras had a filter in front of the target to filter out infrared rays. If the system needed to be sensitive to infrared rays, the filter could be removed. - The noise is divided into shot noise (which exists in any camera) brought by the effective signal and the noise that is not related to the signal inherent in the camera itself (brought by the image sensor read-out circuit, the camera signal processing and amplification circuit, and the inherent noise of each camera is different). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

From January to October 2019, the number of imported cameras and the import amount had exceeded the whole year of 2018, showing that the market value of imported industrial cameras was constantly increasing. 2. ** Market growth factors ** - With the explosion of the machine vision and artificial intelligence industries, the market demand for industrial cameras increased, which also promoted the development of the imported industrial camera market. ** 2. Market share and competitive landscape ** 1. ** Market concentration of different types of cameras ** - In the smart camera market, the global market concentration was much higher than the board camera market. For example, Cognex and Keyence, which were the first to lay out smart cameras, currently accounted for more than 70% of the market, while the top eight companies in the board camera market only had a combined market share of 61%. 2. ** Relationship between regional demand distribution and import market ** - In China, from a regional perspective, the Yangtze River Delta and the Pearl River Delta contributed 70% of the market demand, and the Bohai Rim region contributed about 15% of the market demand. Part of these needs were met by imported industrial cameras. The imported industrial cameras occupied a certain share of the China industrial camera market demand, especially in the high-end market demand. Due to the advantages of foreign products in terms of technology, imported industrial cameras had a large market space. ** 3. The advantages and disadvantages of the product ** 1. ** product advantage ** - Foreign imported industrial cameras had certain advantages in terms of technology. For example, in the field of smart cameras, well-known foreign companies had experience in developing visual software. They usually came with corresponding customized software to facilitate system developers to program smart cameras. For example, the supporting software EasyBuilder for Cognex's In-Sight series of smart cameras had very good functions. Moreover, in terms of industrial machine vision cameras, manufacturers such as Teledyne, Basler AG, and Cognex Corporation accounted for more than half of the global market. The products of these brands were highly competitive in the global market and may have advantages in terms of technology development and product quality. 2. ** Weakness of the product (targeted at the China market)** - The application of foreign products in the China market was not targeted enough. Although the hardware and software advantages of foreign products were obvious, the lack of in-depth development for the China market limited its further expansion in the China market to a certain extent. ** 4. Price factor ** - The price of imported industrial cameras was relatively high. Taking smart cameras as an example, foreign products were priced at a higher level due to their hardware and software advantages. This affected the further expansion of their market share to a certain extent, and also provided opportunities for domestic companies to enter the low-end market. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Image output format for industrial cameras
Industrial cameras output raw data (raw data), its image output format includes RAW (or RAW rmb), which is the raw image format output by the mos image sensor. It is an unprocessed and uncompressed format, which can be regarded as "raw image coding data" or "digital negative film". It also records the raw data generated by the camera (such as the settings of the camera, shutter speed, aperture value, white balance, etc.). It can also output Mono8, Mono12, etc., as well as JPG, BMP, etc. for image storage. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Internal and external parameters of industrial cameras
The intrinsic parameters of the camera were parameters related to the camera's own characteristics, such as the focal length of the camera, the size of the camera, etc. The intrinsic parameters of the camera were parameters in the world coordinate system, such as the position of the camera, the direction of rotation, etc. The camera was a map between the world coordinates and the pixel-based coordinates. When the world coordinates and the pixel-based coordinates of the control points were known, the map could be calculated. After the calculation, the world coordinates of the control points could be inferred from the pixel-based coordinates, and then subsequent operations such as measurement could be carried out. This kind of calibration-based method was also known as hidden parameters calibration-based method because it did not calculate the internal parameters of the camera (such as the focal length of the camera, the distortion coefficient of the camera, etc.). In the process of image measurement and machine vision applications, in order to determine the relationship between the three-dimensional geometric position of a point on the surface of a spatial object and its corresponding point in the image, a geometric model of the camera image must be established. These geometric model parameters are the camera parameters. Under most conditions, these parameters need to be obtained through experiments and calculations. This solution process is called camera calibration1. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
