Embodiment Construction

[0056] The specific implementation process of this technology is as follows: figure 2 shown. The technical realization is mainly composed of five functional modules: camera control module, motion detection module, vehicle capture module, vehicle logo positioning module, and vehicle logo recognition module.

[0057] The camera control module performs linkage control on the camera-acquisition card according to the obtained video, and also controls the camera through the image details in the case of vehicle capture, so as to obtain the vehicle logo recognition requirements. video image.

[0058] The motion detection module completes the collection of odd and even fields, and performs block motion calculation according to the odd and even field images to obtain the required motion parameters.

[0059] The vehicle capture module receives various motion parameters, detects the direction of vehicle motion according to the motion tracking algorithm, and captures a complete picture ...

Abstract

An accurate high-speed moving vehicle mark identification method based on video belongs to a calculation processing method adopting image and mode identification technology to realize vehicle detection and vehicle mark identification. The present invention mainly comprises five function modules, namely a video camera control module, a motion detection module, a vehicle snapshot module, a vehicle positioning module and a vehicle identification module. The present invention acquires a real-time video image through a camera system, judges whether a vehicle passes by processing the video image, judges the motion direction of the vehicle according to motion characteristics, segments a picture of the moving vehicle from an image sequence, positions a vehicle mark through vehicle texture features, and performs classification identification to a vehicle head mark or a vehicle back mark by utilizing vehicle mark features before and after. The present invention can solve the vehicle model and vehicle mark identification of high-speed running vehicles, especially the identification of vehicle back marks.

Description

technical field [0001] The invention belongs to the technology of image processing and pattern recognition, in particular, it utilizes the technology of image processing and pattern recognition to realize the computer processing system of vehicle detection and vehicle logo recognition. Background technique [0002] At present, foreign vehicle recognition technology research mainly focuses on low-speed vehicle and license plate recognition. The identification and classification of vehicle types (such as small cars, large trucks, etc.) is very rough. For example, Autoscope products are only divided into three categories: large, medium, and small. Therefore, the general recognition ability and performance are poor, and it is mainly used for parking detection at toll stations. It cannot identify high-speed moving vehicles, and there is no technology for accurately identifying vehicle signs (front and rear signs). There are also many domestic units conducting research on vehicle...
