The paper puts forward to design a camera controller in view of the computer at the receiving industrial high-definition camera through the image acquisition card transmission of image data signal processing operation of low speed and oneness. The controller connects with the camera through the Camera Link cable at the device end, makes use of FPGA （Field Programmable Gate Array） for image acquisition and algorithm implementation. Algorithms run on the computer is transplanted into the equipment, process the completed data is sent to the computer via Ethernet.Compared with the original method, the method can make full use of the FPGAto the signal of high speed parallel processing ability and is able to complete the image transmission of 300 frames per second, real-time extraction of each frame image centroid coordinates for the use of comput
