Embodiment Construction

[0028] The embodiment of the present invention aims to provide a nighttime vehicle detection and tracking method. By selecting a suitable detection area, the minimum pixelation process is performed on the outside of the lane line, and the noise outside the lane line is removed, which is beneficial to the selection of the best binarization threshold. ; Through the template operation of binary processing and digital image processing, the lamp information is extracted, and the probability of misclassification between the lamp and the background information can be reduced to ensure the accuracy of the binary image; finally, according to the extraction and tracking of the lamp information Detect and track vehicles at night; without a lot of technical calculations, the accuracy is high. The embodiment of the present invention is suitable for detection and tracking of vehicles at night.

Abstract

The invention discloses a method for detecting and tracking a vehicle at night and a device thereof, which relate to the technical field of vehicle detection and aim at solving the problem that the vehicle detection and tracking technology in the prior art unfits the vehicle detection at night. The method comprises the steps of determining a detection zone, carrying out image acquisition and digital image processing of the detection zone so as to obtain car lighting data, and detecting and tracking the vehicle according to the car lighting data. The device comprises a determination unit in the detection zone, an image acquisition and processing unit and a detecting and tracking unit. The method and the device can capture the car lighting data so as to realize the tracking and detection of the vehicle at night according to the characteristic data of the car lighting and apply less technical computing. In addition, the method and the device can be applied to a traffic monitoring system and a household security inspection system.

Description

technical field [0001] The invention belongs to the technical field of detection and tracking, and relates to a method and device for detecting and tracking vehicles at night. Background technique [0002] The current night vehicle detection and tracking technology is the same as the daytime vehicle detection and tracking technology, mainly using background-based methods and motion information-based methods. The background-based method mainly uses the background image to detect and track the target, but at night, due to the influence of vehicle lights, this method is not very effective; the method based on motion information also has problems for night mode, due to the light The existence of light information will also be regarded as motion information, and a large amount of calculation is required. [0003] The Chinese patent document with application number CN200610080495.9 discloses a vehicle detection and tracking method based on machine vision, which is a specific exam...
