Description

technical field [0001] The invention relates to the technical field of industrial cameras, in particular to an industrial camera. Background technique [0002] With the development of machine vision, the requirements for the front-end image and video acquisition system are getting higher and higher. The front-end industrial cameras are required to output higher resolution and frame rate, higher image preprocessing capabilities, and at the same time have greater transmission bandwidth and longer transmission distance. [0003] At present, many high-end image sensors designed by some semiconductor companies can already achieve a data output of more than 10Gbit / s, but limited by the computing power of embedded processors, they cannot complete the necessary image preprocessing in real time. At the same time, the bandwidth of traditional industrial camera interface design rarely exceeds 10Gbit / s. Failed to give full play to the performance that the image sensor should have. ...

AI Technical Summary

Problems solved by technology

The existing industrial camera interface transmission technology can no longer meet the high bandwidth requirements of back-end data processing

[0005] General industrial cameras use low-speed multi-channel or high-speed single-channel interface, which limits the bandwidth requirements for multiple hosts to access the same high-speed industrial camera, and does not meet the application requirements for high-speed multi-channel

[0006] At the same time, traditional high-speed industrial cameras generally require corresponding capture cards. During the early stage of camera installation and commissioning, because there is no corresponding capture card on site, it is impossible to view the actual image and video effects in real time, resulting in difficulties in deployment.
