Abstract

The invention relates to an obstacle detection and garage position distinguishing method of an intelligent parking system. The method comprises the following six steps: completing data acquisition depending on radar and a positioning system; realizing global localization of obstacle data points depending on transformation of coordinates; realizing the classification of the data points by analyzing the geometrical relationship among the data points; realizing the fitting of the data points depending on an optimal exterior rectangle fitting algorithm; realizing garage position distinguishing by analyzing the geometrical relationship among rectangular fitting results; realizing data transmission depending on a garage position information protocol. The invention further discloses an obstacle detection and garage position distinguishing system of the intelligent parking system for implementing the method. The obstacle detection and garage position distinguishing system comprises a sensor unit and a signal processing unit. The garage position detection of a vehicle along any route in a certain range can be realized for a garage position with front and rear fixed obstacles, a used garage position detection algorithm accords with the rule that the geometrical information of the garage position is distinguished by human better, and the system has higher detection precision, reliability and practical value.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a driving assistance technology, in particular to an obstacle detection method of an intelligent parking system. Background technique [0002] With the increase of car ownership, the parking space becomes more and more tense, and the problem of parking difficulty becomes more and more serious. Parking a vehicle safely in a storage space can be difficult for an inexperienced driver; even for an experienced driver, parking a vehicle in a small storage space is not an easy task. The development of an intelligent parking system is conducive to ensuring the safety of the parking process while improving the comfort and convenience of the parking process. [0003] The intelligent parking system generally includes the following modules: warehouse location detection module, path planning module, path tracking module, execution module and man-machine interface module. The storage locat...
