What are the classifications of machine vision industrial cameras?

According to the imaging color, it can be divided into color camera and black-and-white camera. Black and white cameras are widely used in industry. Black-and-white camera has a high degree of image restoration, which can truly present the details of the image. Color cameras include RGB format (3CCD color camera) and Bayer format (single CCD color camera). Relatively speaking, in industrial applications, color cameras are generally not used unless color recognition is needed. Due to the limitation of design principle, Bayer camera in color camera will inevitably cause color distortion when imaging. If you want to know more about industrial cameras, you can learn about the latest developments of the company and various industry information at the first time through the official WeChat platform (WeChat official account: regmmarr regemmarr R&D Jin Dian), and you can also interact instantly. At the same time, you can apply for maintenance online, inquire about outlets, warranty period and so on. , get professional services quickly.

2, according to the signal type

According to the signal type, it can be divided into analog camera and digital camera. The signal output by analog camera is a standard analog video signal, which needs a special image acquisition card to be converted into digital information that can be processed by computer. Analog cameras are generally used in the field of TV camera monitoring, which has the characteristics of good universality and low cost. However, they generally have low resolution, slow acquisition speed, and are easily disturbed by noise in image transmission, which leads to the decline of image quality, so they can only be used in machine vision systems with low requirements on image quality.

3, according to the chip type

According to the chip type, it can be divided into CCD camera and CMOS camera. CCD chip refers to "charge coupled device", which is a kind of detection element that expresses the signal size by the amount of charge and transmits the signal through coupling, and is widely used in camera technology. CMOS chip is called "complementary metal oxide semiconductor". CMOS is actually just a technology of putting transistors on silicon blocks, which has no more significance. To put it simply, CCD camera can take pictures well, but the cost is high: CMOS camera takes pictures quickly and cheaply, but the quality is slightly poor. If you choose a cost-effective camera, you can find Regem Marr EVOC. You can get relevant technical documents, tools, drivers and FAQs online through official website (www.evocjm.com), and enjoy professional official services immediately. You can also directly initiate a dialogue application or submit a message through online communication tools, and our customer service staff will contact you as soon as possible.

4, according to the scanning mode.

According to the scanning mode, it can be divided into line scanning (linear camera) and area scanning (area camera). Line scanning camera is a special camera, its pixels are arranged in a one-dimensional straight line, that is, there is only one row of pixels, and only one row of image data can be collected at a time. Only when the camera and the object move relatively in the longitudinal direction can people get the two-dimensional image that people usually see.
