In order to realize the ultra high-speed image storage in the high accuracy measurement of opto-electronic tracking and measuring system, an image storage scheme based on Double-data Rate Dual In-line Memory Module(DDR DIMM) array technology is put forward. By using the DDR DIMM memory as storage medium and the Field Programming Gate Array(FPGA) as memory controller, a storage system is established. The block diagram of overall design is introduced,then the modules of DDR DIMM array controller and the methods of image data input and output are discussed. The experimental results indicate that the image data storage rate has come to 1 000 MB/s. Actually, analysis show that the scheme can achieve a higher speed to 1 828 MB/s,which can satisfy the requirements of ultra high-speed image data storage of high frame frequency and high resolution image sensors in the high accuracy measurement of opto-electronic tracking and measuring system.
