Abstract

Real-time detection of object is a hot topic in remote sensing applications. In this field, deep network has shown large potential in terms of accuracy. However, it is difficult to design a lightweight hardware and software system to satisfy the satellite edge deployment due to the complexity of the structure of deep network, large amount of computation and high demand for computing resources and storage. In this article, we propose a lightweight object detecting system, based on MPSoC FPGA processor, to solve the problems. First, the lightweight algorithm for object detection which is suitable for the deployment of satellite edge devices is studied. Then, to reduce the number of parameters and the overhead calculation and storage, a network parameter compression algorithm based on dynamic mapping is laid out. Finally, a prototype verification system based on MPSoC FPGA processor is constructed to realize aircraft object detection. The experimental results highlight that the accuracy of detecting the aircrafts can reach more than 92%. For single frame image with input size of 416×416, the reasoning time is reduced to 7ms, suggesting that the requirement of real-time processing of remote sensing target detection can be met.
