基于超声波雷达的泊车位类型检测

Parking Space Type Detection Based on Ultrasonic Radar

环境感知系统作为自动泊车系统的基础,其系统鲁棒性和精确性对于泊车成功率有着决定性的作用。目前车位检测方法主要分为测距技术和视觉技术两种。文章通过探讨超声波雷达的测距变化特点,对车位检测方法进行研究,确定不同类型泊车位情况下的车位约束条件,分辨待泊入泊车位的具体类型,为自动泊车做理论基础准备。

As the basis of the automatic parking system,the environmental perception system has a decisive effect on the parking success rate due to its robustness and accuracy.At present,parking space detection methods are mainly divided into two types:ranging technology and vision technology.This article explores the characteristics of ranging changes of ultrasonic radar,studies the parking space detection methods,determines the parking space constraints in different types of parking spaces,distinguishes the specific types of parking spaces to be parked in preparation for automatic parking.The detection principle is analyzed,and the limitations of parking space detection based on visual sensors are compared.The advantages of ultrasonic radar in parking space type detection are explained.
