Abstract

This paper designs an image processing platform suitable for spaceborne equipment with FPGA and DSP as the core. In this paper, the hardware architecture, the selection of key components, and the interaction design of the interface between FPGA and DSP are introduced in detail. During the experiment, six high-definition cameras were used to capture multiple images of the visual target fixed in the motion mechanism, and the function and performance of the system were fully tested. The results show that the platform has the ability to receive image data from six high-definition cameras at the same time while only consuming 18w of power. And within 0.5s, based on the image data of the visual target captured by the six cameras, after image preprocessing, image noise reduction, threshold segmentation and other related processing, the relevant pose information is solved, the position error is less than 1mm, and the attitude error is less than 0.1°, the platform has high computing precision, fast computing speed, good stability and low power consumption.
