A vehicle length determination method, device, equipment and storage medium

Abstract

The present invention relates to the field of traffic technology, and discloses a method, device, equipment and storage medium for determining the length of a vehicle to improve the accuracy of determining the length of a vehicle. The method in this embodiment includes: determining The speed of the target vehicle in the target area is collected multiple times during the interval; wherein, the first moment is the moment when the head of the target vehicle reaches the preset mark on the target area; the second moment is the moment when the vehicle head of the target vehicle The moment when the tail leaves the preset mark; the moment when the front of the target vehicle reaches the mark and the time when the rear of the target vehicle leaves the preset mark is based on multiple acquisitions of images containing the target vehicle Determined; determine the displacement of the target vehicle from the first moment to the second moment according to the speed of the target vehicle; determine the length of the target vehicle according to the displacement.

Description

technical field [0001] The present invention relates to the technical field of transportation, in particular to a vehicle length determination method, device, equipment and storage medium. Background technique [0002] With the rapid development of the transportation industry, people pay more and more attention to traffic safety. Vehicle length affects early warning information such as time occupancy rate, space occupancy rate, inter-vehicle distance, front vehicle distance, and vehicle time distance. Therefore, obtaining vehicle length in time is very important for traffic safety. [0003] In related technologies, when a vehicle enters the image collection area of ​​a camera installed above the road, the camera captures an image containing the vehicle, and estimates the length of the vehicle based on the imaging length of the vehicle in the image. [0004] However, there is a deviation between the imaging length of the vehicle in the image and the theoretical length that t...

Problems solved by technology

[0004] However, there is a deviation between the imaging length of the vehicle in the image and the theoretical length that the vehicle should be imaging, and many factors such as camera performance, vehicle type, vehicle length, and the location of the vehicle during imaging will affect the size of the deviation, so it is impossible to accurately obtain the length of the vehicle. Therefore, the length of the vehicle estimated by the above scheme has a large deviation from the actual length of the vehicle.
