Abstract

The invention provides an in-tunnel vehicle detection method based on monitored images. The method comprises the following steps: a processor receives in-tunnel road surface area images at a present tunnel illuminating lamp brightness level acquired by a monitor camera in real time; processing is carried out according to characteristic areas of the road surface area images and characteristic areas of background images which are the same with the road surface area images in terms of illuminating lamp brightness; the background images are images acquired when no vehicle exists in a tunnel; and the processor determines whether a vehicle exists in a tunnel according to the processed result. The invention realizes detection of vehicles in the tunnel, and raises the accuracy of detection results.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image data analysis, and in particular to a method for detecting vehicles in tunnels based on surveillance images. Background technique [0002] At present, the commonly used method of vehicle detection technology in tunnels is to use equipment such as ground sense coil vehicle detectors, infrared detectors or radar speedometers to detect whether there is information on vehicles. In actual application, the installation and construction cost of the ground induction coil is high, the damage to the road surface is serious, the wiring is complicated, it is not conducive to lightning protection, and the cost of maintenance is too high, which has great limitations; the installation of infrared detectors is limited by the highway roadside guardrail The impact of the vehicle and the phenomenon of missed detection for vehicles with too fast speed; the radar speedometer may also cause missed d...
