Vehicle weight detection method, device and storage medium based on video recognition

Abstract

The invention discloses a vehicle weight detection method, device and storage medium based on video recognition. The structural parameters of the vehicle to be tested, the quality parameters of the first degree of freedom and the vibration response signals of each degree of freedom are recognized from the vibration video of the vehicle to be tested; The vibration response signals of each degree of freedom of the vehicle to be tested are calculated, and the vibration modal parameters of the vehicle to be tested are calculated through the SSI modal identification algorithm; the vehicle state equation is constructed according to the structural parameters and vibration modal parameters of the vehicle to be tested, and the The vibration response signal is input into the vehicle state equation, and iteratively solves the ratio of the mass of the vehicle to be tested with different degrees of freedom; according to the ratio of the mass parameter of the first degree of freedom of the vehicle to be tested and the mass of the different degrees of freedom to calculate The weight of the vehicle to be tested. Compared with the existing dynamic weighing, it is suitable for the detection of the vehicle weight value of various types of vehicles, and has strong universality, simple operation, no damage to the vehicle, and low detection cost.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of vehicle engineering vehicle physical information detection, and in particular to a vehicle weight detection method, device and storage medium based on video recognition. Background technique [0002] With the rapid growth of industrial and commercial trade, the competition in the road transport industry is increasing, and the phenomenon of over-limit and overloaded transport is increasing. Accurate and efficient acquisition of vehicle weight values ​​​​is conducive to the governance of vehicle overloading problems, so that road transport can be regulated , Eliminate traffic hazards and reduce economic losses. [0003] At present, my country's highway control overrunning and overloading generally adopts a weight-based toll system based on dynamic weighing. Most of these traditional weighing methods require the establishment of large-scale inspection stations on the main road of th...
