Abstract
Unmanned aerial vehicles continue to increase the requirements for image resolution in the fields of reconnaissance, surveying, and mapping. The fusion of the video image system and the traditional remote control and telemetry system also needs to be considered in the design. Aiming at the above problems, the article designs and implements an airborne high-definition video image system based on FPGA+DSP. The system can store the video image on the local hard disk, and at the same time, the compressed video image is also convenient for real-time transmission to the ground control station through the wireless link equipment. The system detection found that the buffer occupancy can fluctuate smoothly in a small range, and the subjective image quality has also been improved, which better meets the low-latency application requirements of the airborne reconnaissance system.
