FPGA Implementation of HoG-based Space Target Distance Measurement

This paper focuses on space cooperative target identification and ranging using monocular CMV4000 CMOS sensor and Xilinx Zynq-7000 Soc based platform without the operating system that adopts Histograms of Oriented Gradients (HOG) descriptor and Support Vector Machine (SVM) for classification. With Vivado High-Level Synthesis to accelerate IF creation by enabling C specifications to be directly targeted into devices, this implementation allows for two high-resolution images (2048×2048 pixels) processing per second. The hardware and software co-design of Xilinx Zynq7000 promises the accuracy of space target classification and distance measurement and thus meets the requirement of realtime space application.
