Abstract:

The principle of the cylinder projection arithmetic is introduced.A system design based on hardware logic is presented.The design starts with writing the image data into DDR2 SDRAM,and then realizes the cylinder projection arithmetic with hardware logic on Cyclone III series FPGA produced by Altera company.At the same time it creates a CameraLink schedule which is delivered to the backend,and then displays the converted data on LCD via DVI interface in real time.The display results on LCD show that the cylinder projection realized by hardware achieves anticipated results.

Key words: FPGA;cylinder projection;Cameralink;DDR2 SDRAM
