Parking position detecting device and method of intelligent parking system

Abstract

The invention discloses a parking position detecting device of an intelligent parking system. The parking position detecting device comprises a sensor unit, a signal processing unit, and a man-machine interface unit. The sensor unit comprises four wide-angle cameras and an ultrasonic ranging sensor. The signal processing unit comprises an annular view generation module and a parking position detecting module. The man-machine interface unit comprises an output module used for displaying an annular view and detected garage positions, and an input module used for receiving various commands inputted by a driver. The parking position detecting module comprises a garage position line detection submodule, an obstacle vehicle detection submodule and a parking position output submodule. The invention further discloses a parking position detecting method of the intelligent parking system. A low-cost sensor scheme is adopted, accuracy and precision of parking position detection are improved by mixing distance value obtained by the ultrasonic ranging sensor with image information collected by the cameras, and parking positions can be effectively detected under multiple conditions that garage lines and obstacle vehicles exist on a ground.

Description

Technical field [0001] The invention belongs to the technical field of automobiles, and relates to a driving assistance system, in particular to a parking space detection device and method of an intelligent parking system. Background technique [0002] With the increase in car ownership, parking spaces are becoming increasingly scarce, and the problem of parking difficulties has become more serious. For inexperienced novices, it is very difficult to park a vehicle safely in a parking space; even for experienced drivers, parking a vehicle in a small parking 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: parking space detection module, path planning module, tracking module, execution module and man-machine interface module. The parking space detec...
