Abstract

This invention provides an industrial image collection system based on a USB 3.0 interface, and an image collection processing method of the industrial image collection system. The system comprises a Camera link interface, an image collection processing module, a storage module and the USB 3.0 interface. The image collection processing module includes a pixel synthesis module, an image pre-treatment module, a data buffer module, an image post-treatment module and a USB 3.0 bus control module which are sequentially connected, and also includes a command analysis module connecting with the USB 3.0 bus control module. The system provided by the invention is realized based on the USB 3.0 interface, fully supports 8 bit, 10 bit, 12 bit, 14 bit, 16 bit, and RGB 24 bit image collection in the Camera Link Base mode, and has the advantages of high transmission speed, good portability and high compatibility with the PC. The cost of a USB 3.0 collection device is lower as compared with image collection devices of other interfaces, so that the system shows an advantageous cost performance.

Description

technical field [0001] The invention relates to the technical field of industrial image acquisition of machine vision, in particular to an industrial image acquisition system based on a USB3. 12bit, 14bit, 16bit and RGB24bit image acquisition, the maximum pixel clock frequency is 85MHz. Background technique [0002] With the continuous development of technology, machine vision has begun to be widely used in industrial production, which greatly improves production efficiency and reliability, and plays an important role in the fields of working condition monitoring, finished product inspection and quality control. In a complete machine vision system, image acquisition is of great significance, because after image acquisition, the video signal can be converted into a digital format used by the computer. [0003] Industrial image acquisition cards have a variety of digital interface types, among which USB3.0 is a serial communication specification for a new generation of pl...
