Embodiment Construction

[0018] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, and the described embodiments are only used as examples for illustration, and are not intended to limit the present invention. The specific implementation of the present invention requires some common video processing modules, such as preprocessing and background modeling, which will not be described in detail here. The invention is applicable to the urban road traffic information detection system. The obtained road vehicle queuing data information can be transmitted to the traffic signal controller for road optimization control, and can also be transmitted to the traffic information collection center system to provide sustainable basis for scientific analysis and management of road traffic.

[0019] first as image 3 As shown, the video detection area needs to be set up. The video detection area includes the detection line at one end of the video d...

Abstract

Disclosed in the invention is a video-tracking-based vehicle queuing length calculating method. On the basis of a video tracking result, a moving or stopping state of a vehicle on a road is analyzed effectively and a road traffic state is determined; and whether a queue congestion state occurs is determined. According to a vehicle tracking path, whether a same vehicle stops at a parking line position is determined in real time; if a parking queue occurs, a moving track of a tacked vehicle on the road is analyzed and the queue length is determined. Therefore, accurate road traffic vehicle queue length information can be obtained and thus a basis is provided for analyzing and managing the road traffic scientifically.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a calculation method for vehicle queuing length. Background technique [0002] With the expansion of cities and the rapid growth of motor vehicles, road congestion has become a serious "big city disease". By detecting real-time road traffic information, scientific analysis and management of urban traffic roads can greatly alleviate road congestion and other problems. Accurate collection and analysis of road vehicle queuing length is an effective means for scientific analysis and management of road traffic conditions. At present, the vehicle queue length detection methods based on video mainly include: vehicle queue length detection based on projection method, and vehicle queue length detection based on edge segmentation. [0003] The vehicle queue length detection method based on the projection method is to project the brightness of the detection area on the road direc...
