high data rates and high grayscales of remote sensing CCD cameras at present
a new fast-view system by using parallel processing technology based on Field Programming Gate Array(FPGA) is proposed and performed. The system consists of a high-speed mass storage unit
a pre-treatment unit and a high grayscale display unit. The high-speed mass storage unit directly controls large-capacity SATA disk arrays by using FPGA to implement the high speed storage of mass image data. The pretreatment unit processes the mass image data by zooming
translation and data fusion in real time
by which overcomes the technical bottlenecks of the processing speeds of traditional fast-view systems. Moreover
high grayscale
large format and seamless image data is displayed on three 12-bit monitors by high grayscale display unit. The results show that the system has a storage capacity up to 96 TB
and can record and display 12-channel CCD image data quantified by 12-bit at the total rate up to 19.7 Gb/s in real-time . The system is reliable
easy to expand and has been successfully applied in many types of development tests of remote sensing cameras.
