Abstract

The invention discloses an automatic vehicle overall size measuring system and method based on vision. The system comprises four cameras, four pan tilts, a transverse horizontal camera support, a longitudinal horizontal camera support, an image collection card, a computer system and a position sensor. Each camera is installed in one pan tilt. Two cameras are fixed to the transverse horizontal support, and the other two cameras are fixed to the longitudinal horizontal support. The position sensor is installed at the position, being about to enter the view field range of the cameras, of a vehicle and used for sensing the position of the vehicle, and provides a trigger signal for the computer system. The automatic vehicle overall size measuring system can reduce the cost and has the advantages of being automated, contactless, high in precision, high in adaptability and the like, and can effectively recognize overrunning vehicles, overload vehicles and other illegal vehicles, meet the requirements of vehicles for comprehensive performance detection, and improve highway traffic system monitoring performance and the vehicle management level.

Description

technical field [0001] The invention relates to a vision-based automatic measurement system and method for vehicle outline dimensions. Background technique [0002] In recent years, frequent traffic accidents have occurred due to vehicle overloading, illegal modification, etc., seriously affecting national property and people's lives. In order to effectively prevent problems such as over-limit and overloading of vehicles, "big ton and small labels", and illegal modification from the source, and ensure the safety of vehicles, the parameters of vehicle dimensions have become one of the important contents of vehicle operation safety inspections. [0003] Through the research on the existing vehicle outline dimensions, it is found that: at present, domestic public security vehicle management offices, motor vehicle inspection stations, etc. basically continue to use manual measurement methods such as steel tapes in the past for the inspection of vehicle outline dimensions, and th...
