Abstract

The invention relates to the technical field of ultrasonic waves, and discloses a detection method, device and equipment based on an ultrasonic sensor and a storage medium, which are used for improving the accuracy of a positioning area of an obstacle and reducing the risk of collision with the obstacle. The method comprises the following steps: selecting at least one ultrasonic sensor from a plurality of ultrasonic sensors as an active detection sensor, and determining at least one ultrasonic sensor adjacent to the active detection sensor as a passive detection sensor; an ultrasonic detection signal is sent through an active detection sensor; obtaining an active detection result of the active detection sensor and a passive detection result of the passive detection sensor; and determining a prediction area of the target obstacle according to the active detection result and the passive detection result.

Description

technical field [0001] The invention relates to the field of ultrasonic technology, in particular to a detection method, device, equipment and storage medium based on an ultrasonic sensor. Background technique [0002] With the rapid development of smart transportation, more and more cars use ultrasonic sensors for assisted driving. [0003] The vehicle-mounted ultrasonic sensor converts the electrical signal into an ultrasonic signal through the inverse piezoelectric effect of the piezoelectric crystal. The ultrasonic signal is reflected back after encountering the target object. The electric effect is replaced by an electric signal, and the distance between the ultrasonic sensor and the target can be calculated by the time difference between the transmitted signal and the received signal and the speed of sound. [0004] However, the existing solutions can only detect the approximate orientation of the obstacle, and cannot accurately locate the area where the obstacle is l...
