Abstract

The present application provides a method, device, system, and storage medium for detecting the space occupancy rate of a vehicle compartment. The method includes: controlling the acoustic wave generating module to transmit a transmission signal with a preset time length to the vehicle under test; calculating the echo signal received by the acoustic wave receiving module. Duration, the echo signal is the sound wave signal reflected back by the transmitted signal after passing through the compartment; the space occupancy rate of the compartment to be tested is determined according to the preset time length of the transmitted signal and the duration of the echo signal.

Description

technical field [0001] The present application relates to the technical field of detection and identification, and in particular, to a method, device, system and storage medium for detecting the space occupancy rate of a compartment. Background technique [0002] The existing method of detecting the space occupancy rate of the carriage is to set up a plurality of detection points at a certain distance from each other on the top of the carriage, and use the detection points to detect the remaining space height of the car directly below, and then according to the height information detected by each detection point. And the interval between detection points to calculate the remaining space size of the car. [0003] The above-mentioned method needs to install a plurality of detection points on the carriage when detecting the space occupancy rate of the carriage, which is not common and inconvenient among different vehicles. SUMMARY OF THE INVENTION [0004] The purpose of the...
