Abstract :
For multi-channel high-speed image data of certain space remote sensing camera, this paper proposed a new image data acquisition and storage system. First of all, the system uses Field-Programmable Gate Array(FPGA) controlling synchronous dynamic random access memory(SDRAM) array to realize the cache of image data, then according to the received commands, sends certain channel´s image data to the acquisition card to write the image data into SCSI hard disk and implements the final storage. A Time Delay Integral Charge Couple Device(TDICCD) image data acquisition and storage system with five channels is developed, pixel clock rate is up to 96MHz,total effective data rate is up to 2.88Gb/s, single channel storage depth is up to 7810 lines. The experimental results indicate that this system work stably, high effectively which can meet the requirement of acquisition and storage of multi-channel high-speed TDICCD image data.
