The invention discloses an FPGA acceleration fusion method for dynamic resource data of a parking lot in a service area, and the method comprises the following steps: constructing a panorama camera-radar space-time synchronization architecture based on FPGA hardware acceleration, splicing panorama camera images in real time, and aligning the panorama camera images with a timestamp of a radar point cloud; cooperatively deploying a vehicle detection model and a radar tracking algorithm on an edge computing platform, and constructing a heterogeneous cooperative architecture of an FPGA and the edge computing platform; and constructing a traffic flow prediction model of a convolutional neural network-long and short-term memory network, and carrying out adaptive collaborative optimization design of an adjustment mechanism on the obtained traffic flow prediction model and hardware parameters of the panoramic camera in the service area. The beneficial effects of the invention are that the programmable trigger circuit based on the FPGA generates independent pulse signals with adjustable phases, the independent pulse signals drive the camera array and the radar sensor respectively, global clock synchronization is realized in combination with a PTP protocol, and time sequence accumulated deviation among multiple devices is effectively eliminated.
