Title The design of collecting image procedures in high-speed digital processing system
Abstract In military and civilian, the image acquisition has a very important position.it is a important way to collect and process images, the application of high-speed digital signal processing techniques to image observation.now-days, gathering is a very important area of research.at home and abroad.
In this paper,we have studied the image hardware and software design of image acquisition by consulting mang domestic and foreign researches about technology base and application examples and referring to the relevant papers. On the hardware we chose TI's DSP DM642 chip as the core of the system image acquisition devices, SDRAM to store images, and programs.Then,we have completed the images from the camera input, encoding,processing, decoding and output and a series of processes. And to the hardware platform for software experiments have proved the correctness of the program.
