[Abstract]:With the continuous development and progress of modern society and the increasing demand for military equipment and civilian equipment, and the continuous improvement of its requirements, the recognition and tracking technology of moving targets has rapidly developed into a crucial technology in the field of modern information processing, and this technology is also the field battlefield reconnaissance of UAV. The key and difficult points, and play an irreplaceable role in many applications. At present, the development of target detection and tracking technology based on PC has become mature, but the research on the application field of visual technology based on embedded platform is still in the primary stage. Because the embedded system has small size, easy to carry and so on The advantages of PC, which can not be replaced, are used in unmanned aerial vehicle field reconnaissance, tracking targets and so on, which can greatly improve the effect of UAV. Therefore, how to detect and track the moving target effectively and realize it in embedded system is an urgent problem to be solved at present.
In this paper, the background, significance and research status of the research on the visual intelligent tracking system based on embedded platform are summarized, and the importance of the research is illustrated by analyzing the current development status of the research on the visual intelligent tracking system at home and abroad and the practical problems faced in the application. Then a kind of embedded S3C2410 based on ARM is proposed. The design of the visual inspection and tracking system of the device, and the key design methods involved in the system are described in detail, including the selection of the embedded core processor and the selection of the embedded operating system. Secondly, the hardware platform and the software design of the embedded visual intelligent tracking system are introduced in detail, in which the ARM is designed. The construction of the -Linux platform, the USB camera driver, and the transplant of the OpenCV library are emphasized. Then the target detection and tracking algorithms used in the system are described in detail, and the effectiveness of the algorithm is verified by the simulation experiment.
Finally, through the experimental simulation, the rationality of the proposed design scheme of the visual intelligent tracking system based on the embedded platform is verified, and the direction of the future development of this research is pointed out. This method of analysis and design has some guidance and reference for the embedded application of the visual tracking system.
