Detection method, apparatus, and system of oversized vehicle

Abstract

The embodiment of the invention, which relates to the intelligent traffic field, discloses a detection method, apparatus, and system of an oversized vehicle, thereby improving detection accuracy of an oversized vehicle based on simplification of hardware complexity. According to the embodiment of the invention, when occurrence of a vehicle licence plate in a current view is identified, two shooting units of a binocular camera are triggered to carry out synchronous shooting on a same to-be-detected vehicle and two image frames that are obtained by synchronous shooting are obtained; contours of the to-be-detected vehicle in the two image frames are identified, and a three-dimensional contour model of the to-be-detected vehicle under the world coordinate system is constructed according to the identified contours as well as a relative pose between the two shooting units of the binocular camera; statistics of a distribution situation of all pixel points under the world coordinate system in the three-dimensional contour model is carried out, and the size of the to-be-detected vehicle is determined according to the statistical distribution situation; and when the size exceeds a preset threshold value, the to-be-detected vehicle is determined to be an oversized vehicle. Therefore, the problems in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a detection method, device and system for an overrun vehicle. Background technique [0002] Overrun vehicles refer to transport vehicles whose total weight of vehicle and cargo and the length, width and height of the goods carried exceed the limit values ​​stipulated by the state (the limits set by the state can be found in the "Regulations on the Administration of Overrun Vehicles Driving on Highways" (Ministry of Communications, 2000) Order No. 2) and related regulations). In practical applications, compared with the problem of overweight, the problems of super length, super width and super height are easy to be ignored, but the latter three kinds of overweight vehicles will also increase the probability of traffic accidents when driving, bringing great danger , especially will cause serious harm to facilities such as bridges, signs and toll booths on the road. There...

Problems solved by technology

[0004] In the prior art, since the measurement point of the laser beam is relatively single, it is generally necessary to install multiple sets of laser distance measuring devices at multiple positions to complete the measurement of the length, width and height of the vehicle; since the installation points of the laser distance measuring devices are fixed , in order to improve the accuracy of detection, it is necessary to install more laser ranging devices at various positions on the beams, vertical beams and gantry; it can be seen that the laser ranging method in the prior art has high installation complexity and hardware Defects with high cost and low measurement accuracy, so it is difficult to apply to heavy traffic roads
