Abstract

The invention relates to the field of image processing mode recognition, in particular to a DSP + FPGA-based visual target tracking system, which mainly comprises the following processing steps: acquiring image data and receiving a serial port instruction, receiving the image data and an upper computer instruction, tracking a visual target and post-processing the data, and transmitting target deviation measurement data of the system and displaying an image. High-speed data transmission is achieved through a serial high-speed input and output port and an external storage interface between the DSP and the FPGA, mutual data receiving interruption is triggered by changing the pin level of a general purpose input and output port (GPIO) communicated with hardware so as to inform all processes that related data transmission is completed, and high-speed data exchange between the DSP and the FPGA is achieved.

Description

technical field [0001] The invention belongs to the field of image processing pattern recognition, in particular to a visual target tracking system based on DSP+FPGA. Background technique [0002] In the field of computer vision, visual object tracking is a research hotspot and difficulty. Visual tracking estimates the shape, position and occupied area of ​​the tracking target in a continuous sequence of video images, and determines the speed, direction, and trajectory of the target to analyze and understand the target's behavior. At present, it has been widely used in military navigation, intelligent monitoring and medical imaging and other fields. [0003] Among the existing technologies at home and abroad, the main research is to realize the visual target tracking processing on a single FPGA or DSP processor; among them, the programming of the FPGA platform is complicated, which is not conducive to the rapid iterative upgrade of the algorithm program of the processing sy...
