Smart Camera is not a simple camera, but rather a highly integrated micro and small machine vision systems. It will image acquisition, processing and communications capabilities on a single camera, thus providing a multi-functional, modular, high reliability, easy to implement machine vision solutions. At the same time, due to application of the latest DSP, FPGA, and high-capacity storage technology to constantly improve their level of intelligence, can meet a variety of machine vision applications. Smart camera generally consists of image acquisition unit, image processing unit, image processing software, network communication devices, etc., functions of each part is as follows: (1) image acquisition unit In the smart camera, image acquisition unit is equivalent to the ordinary sense of the CCD / CMOS cameras and frame grabbers. It optical image is converted to analog / digital images, and output to the image processing unit. (2) image processing unit Image processing unit similar to the image acquisition / processing card. It can be the image acquisition unit of the image data in real-time storage, and image processing software, support for image processing. (3) image processing software Image processing software, mainly in the graphics processing unit hardware environment with the support of the completion of image processing functions. Such as the geometric edge of the extraction, Blob, histogram, OCV / OVR, a simple positioning and search. In the smart camera, the above algorithms are encapsulated into a fixed module, users can be applied directly without programming. (4) network communication devices Network communication devices, an important component of smart cameras, primarily the completion of control information, images, data communications tasks. Smart cameras generally built-in Ethernet communications devices, and supports a variety of standard network and bus protocols, so that multiple smart camera machine vision systems pose a greater. |
