Abstract

The invention relates to a real-time binocular stereo vision software and hardware collaborative design method based on ZYNQ. The real-time binocular stereo vision software and hardware collaborativedesign method comprises the following steps that real-time calculation processing of binocular stereo matching is completed by utilizing PL in ZYNQ; Multi-task management and data storage control arecompleted through the PS of ZYNQ, data interaction and collaborative design with the PL are completed, and binocular stereoscopic vision processing and data transmission are completed together. According to the invention, the interaction, control and processing of the image data of the PL end and the PS end in the ZYNQ FPGA can be correctly and efficiently realized, and the effect of real-time binocular stereo vision is achieved.

Description

technical field [0001] The invention relates to the technical field of computer vision applications, in particular to a ZYNQ-based real-time binocular stereo vision software and hardware collaborative design method. Background technique [0002] Binocular stereo vision is an important topic in the field of computer vision research. Two cameras in different positions are used to capture two images and obtain depth information from them. Binocular vision requires simple equipment, appropriate precision, and simple system structure. It is widely used in visual navigation, target detection and tracking, target measurement, target recognition, and 3D scene perception. [0003] The related algorithm of binocular stereo vision is complex to realize, and the amount of calculation is large. The complex processing algorithm makes the serial processing operation speed of the CPU instruction set slow, and the real-time effect cannot be achieved. Usually, GPU acceleration or FPGA accele...
