Heterogeneous visual target tracking system and method based on PYNQ framework

The invention discloses a heterogeneous visual target tracking system and method based on a PYNQ framework. The system comprises a target tracking master control module arranged on a PS and a feature extraction operation acceleration module arranged on a PL. An AXI interface and a DMA channel are adopted between the PS and the PL to realize an interaction path between a control flow and a data flow; the target tracking master control module is used for system initialization configuration, video image sequence loading, calling and communication of the feature extraction operation acceleration module, display of a response diagram and output of a target position; and the feature extraction operation acceleration module is used for carrying out deep convolution feature extraction on the target, then carrying out cross-correlation calculation on a feature map and a target model in a frequency domain, further calculating a maximum response, and returning a calculation result to the target tracking main control mod
