To resolve the issue of poor generality of current parking methods based on idle space, a panoramic parking path planning method based on DMPR-PS and Hybrid A-Star is proposed. In this paper, a pure vision approach is adopted, and a fisheye camera is selected as an image acquisition device to build panoramic parking assistance system. Subsequently, the parking slot directional marking points are obtained through DMPR-PS model, and the valid entrance line can be also acquired to recognize parking slot. The accuracy of parking slots recognition can reach 96.86%.Eventually, the planned path can be achieved based on the Hybrid A-Star algorithm where vehicle kinematics and obstacle avoidance constraints are considered. The effectiveness of the planned path can be verified with the adoption of MATLAB and real-vehicle test.
