Abstract

The embodiment of the invention discloses a vehicle parameter detection method and system and a storage medium. The method comprises the following steps of determining position coordinates of radar data in a target coordinate system according to the radar data of at least two laser radars for scanning a vehicle in a driving process, wherein the at least two laser radars are arranged in a staggered manner along two sides of a vehicle driving road, extracting a wheel point cloud according to the position coordinates of the radar data in the target coordinate system, and determining current vehicle parameters of the vehicle according to the position coordinates of the wheel point cloud in the target coordinate system. According to the technical scheme, automatic and accurate vehicle parameter detection can be achieved, the detection cost is reduced, the detection efficiency is improved, and a new thought is provided for vehicle parameter detection.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of laser radar, and in particular to a vehicle parameter detection method, system and storage medium. Background technique [0002] Motor vehicles are an indispensable means of transportation in the rapid development of social economy, and undertake the functions of cargo transportation and passenger transfer. In order to reduce transportation costs, some motor vehicle users modify the vehicle size without permission to increase the single transportation volume of the vehicle. Vehicles that have been modified without authorization seriously violate the safety standards for vehicle use. In order to ensure the safety of vehicles, vehicle parameters (such as wheelbase, wheel diameter, etc.) need to be tested regularly. At present, vehicle parameter detection is mainly based on manual measurement, which has low efficiency, high cost, and low accuracy, and needs to be improved urgently. C...
