Abstract

The invention discloses an obstacle recognition method and equipment, a storage medium and a device. The method comprises the following steps: when an obstacle detection instruction is received, transmitting an initial ultrasonic wave according to the obstacle detection instruction; receiving an initial ultrasonic echo corresponding to the initial ultrasonic wave, and judging whether obstacle position detection is carried out or not according to the initial ultrasonic echo; if obstacle position detection is carried out, adjusting the initial ultrasonic wave according to the initial ultrasonicecho to obtain a target ultrasonic wave, and transmitting the target ultrasonic wave; receiving a target ultrasonic echo corresponding to the target ultrasonic wave, and determining the obstacle position and the obstacle size according to the initial ultrasonic echo and the target ultrasonic echo; and carrying out obstacle recognition according to the obstacle size, the obstacle type and the obstacle position. The obstacle recognition precision is higher, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of ultrasonic detection, in particular to an obstacle identification method, equipment, storage medium and device. Background technique [0002] At present, in the autonomous driving environment perception module, the identification of obstacles mainly relies on ultrasonic sensors, cameras, millimeter-wave radars, and lidars. Camera, but the positioning accuracy of the camera to obstacles is not high, so the market mainly relies on ultrasonic radar for the positioning of obstacles in the short range around the vehicle. However, for the positioning of obstacles, most ultrasonic radars can only provide two-dimensional coordinates, cannot feed back heights, and cannot accurately identify obstacles. Therefore, how to perform obstacle recognition by determining the obstacle position and obstacle size is an urgent technical problem to be solved. [0003] The above content is only used to assist in understanding ...
