In order to obtain largeviewing angle image data, a highresolution circularviewing image realtime acquisition system based on linear CCD was designed. The design of hardware modules of the system was completed, and by using the VHDL language, the driving timing of linear CCD and the A/D convertor controlling timing were designed. A new method of dynamic realtime acquisition of linear CCD image based on VC multithread techniques is proposed. Under the Visual C++ 6.0 environment, the implementation process of realtime image acquisition is presented in detail. The simulating and debugging on hardware and software achieve the expected requirements, completing the realtime acquisition of circularviewing image. And the experimental results show that the scheme is feasible.
