1. According to chip structure: CCD camera &; CMOS camera
2. According to the sensor structure: area array camera &; Line scanning camera
3. Classification by output mode: analog camera &; digital camera
4. According to the output image: color camera &; Black and white camera
Applicable field:
1. With the rapid development and progress of CMOS technology, CMOS cameras have completely replaced CCD cameras. If the target is moving, choose an industrial camera with frame exposure.
2. Linear industrial cameras, as the name implies, have linear imaging sensors. Although it is also a two-dimensional image, it is extremely wide, thousands of pixels wide, but only a few pixels high. This camera is generally used in two situations:
(1) The field of view to be measured is slender, which is mostly used for inspection on the roller.
(2) Large field of vision or high accuracy is required.
3. The analog camera outputs analog signals, which can be directly connected to the monitor or display. If you need to collect or process images, you need to connect an image acquisition card; There is an A/D converter inside the digital camera, and the data has been transmitted in digital form, which can be directly displayed on the computer or TV screen with good imaging quality.
4. If you want to process the color information of the image, or you must watch the color picture for visual effect, you must use the color camera.
In addition, it is recommended to use a black-and-white camera, because at the same resolution, the image accuracy of a black-and-white camera is higher than that of a color camera, especially at the edge of the image.
