A Novel Fast-view System for Multi-channel Remote Sensing Camera

Multi-channel remote sensing camera fast-view system has complex structure and low versatility, and this paper presents a novel multi-channel remote sensing camera fast-view system, which could reduce development cycle and R&D costs. Taking Panchromatic and multispectral camera fast-view system as an example, this paper provides the improved system structure diagram, hardware design and software flow chart. Gigabit network interfaces and protocols are perfectly used to simplify system structure and improve system versatility. UDP protocol is implemented in FPGA hardware pipeline package and parse to improve transmission rate, and selective retransmission mechanism is devised to ensure data reliability. By means of increasing the network traffic at a steady rate up to 100MB/s, the experimental results meet the requirements of versatility design and rate at which the CCD image acquisition system asks for through hardware implementation and verification.
