| Abstract: | In view of the specific demands of aircraft-borne geodetic engineering, this paper achieved an efficient real-time SPIHT compression and storage system based on FPGA and ARM processor. The system has characteristics of high compression performance, good anti-error code ability and adjustable compression ratio, which could carry on real-time compression and storage. The system has been successfully used in some geodetic engineering of the country. |
