The principle of system design is as follows: At first, compartmentalizing the arithmetic of sterovision measurement. We use FPGA logic units Customized hardware blocks to implement the arithmetic which is simple and large data-computing, and the data is transferred on pipeline between each blocks, otherwise, use software program in NiosⅡ to implement the complicated and small data-computing arithmetic. So the system is high-speed and flexible.

For example, the object is composed of four blocks, i.e. block A, B, C, D. Block A locates the left of block B and above block C. According to order, its code is ABDC etc. This code does not change its order after the object rotates, zoom, downsizes. The disadvantage of this method is that it will lose the target when the color is changed.A video fluid is composed of compressed data which include I, P and B(bi-prediction) frame. The data of each block of P frame is predicted by motion prediction and compensation from the data and motion vector of I frame.
