Vehicle window positioning method and vehicle window positioning system

Abstract

The invention provides a vehicle window positioning method and a vehicle window positioning system, and relates to the computer visual technology field. The vehicle window positioning method comprises steps that based on pretreatment of a forward direction detection image of a vehicle, at least a vehicle image area or edge information in the area are acquired; a marker in the vehicle image area is discriminated at least based on the vehicle image area, and the marker comprises a marker body, which is in the vehicle image area, and is independent from a vehicle window; the various boundaries of the vehicle window are discriminated in the edge information at least based on the marker and a preset distance model in order to determine a vehicle window area, and the preset distance model comprises distance relations between the marker and the vehicle window and the boundaries of the vehicle window. The vehicle window positioning scheme provided by the invention is advantageous in that the vehicle window area is discriminated according to the marker and the preset distance model, and the accurate vehicle window positioning is realized, and the marker has good robustness to light and colors, and therefore the vehicle window positioning scheme is better suitable for various different occasions.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a vehicle window positioning method and system. Background technique [0002] In the big data platform of vehicles at city security checkpoints, a very important function is to quickly find the target vehicle according to the special markers in the vehicle's driving window, which will be very useful for analyzing events such as licensed vehicles, unlicensed vehicles, and hit-and-runs. In addition, a series of vehicle "fingerprint" detections such as annual inspection mark detection, co-pilot personnel detection, and front decoration detection need to be located in the corresponding window area. Accurate window positioning is therefore the basis for efficient implementation of several other functions and detections. [0003] At present, there are some studies on car window positioning, most of which are based on image edge detection. In the process of implementing the pre...

Problems solved by technology

[0003] At present, there are some studies on car window positioning, most of which are based on image edge detection. In the process of implementing the present invention, the inventor found that these methods in the prior art have poor positioning capabilities for blurred scenes, night scenes, and high-light scenes. , cannot effectively meet the practical application
