Real-time and High-speed Serial Image Data Acquisition System Design Based LVDS Technology
The LVDS technology is applied in the image acquisition system and real-time and high-speed serial image data acquisition system based on LVDS technology because of the CCD camera on infrared seeker which contains large quantity of image data, multi-path and high transmission speed.The paper emphasizes in discussing the signal transfer method with the modes of seeker data gaze transmitting mode and line scanning alternation transmitting mode.The comparing the characteristics and the influence on system acquisition timing of the following two signal transmission is in processing: the FIFO operation and ping-pong operation.Experiment tests indicate that the Ping-Pong operation will greatly simplify software design of the image acquisition system in image signal of line scanning transmitting mode.The paper build the hardware and software architecture of the real-time display and storage of image signal based on this method.
