The invention relates to the technical field of fee evasion vehicle processing, in particular to a fee evasion vehicle evidence chain processing method and system, and the method comprises the steps: collecting illegal vehicle sample images, building a vehicle management database, scanning and photographing vehicles entering a station, and carrying out the image segmentation, feature extraction and recognition of the vehicles through an image recognition technology. Obtaining structured information of the vehicle, and extracting brand and appearance features in the vehicle image; according to the invention, according to the collected sample image of the illegal vehicle, the vehicle entering the station can be conveniently scanned and photographed, so that the subsequent image segmentation, feature extraction and recognition of the vehicle are facilitated, the structured information of the vehicle is obtained, and when the feature model extracted from the image is matched with the feature model of the sample image, the matching efficiency is improved. According to the method, high-similarity pictures can be searched through a fast nearest neighbor search algorithm, so that pictures are searched by pictures, the pictures can be conveniently compared to obtain evidences, and a fixed evidence chain is formed.

    本发明涉及逃费车辆处理技术领域,尤其为一种逃费车辆证据链处理方法及系统,包括收集违规车辆样本图像,建立车辆管理数据库,对进站的车辆进行扫描拍照,并通过图像识别技术对车辆进行图像分割、特征提取与识别,获得车辆的结构化信息,通过提取的车辆图像中品牌和外观特征;本发明可根据收集违规车辆的样本图像,方便对进站的车辆进行扫描拍照,以便于后续对车辆进行图像分割、特征提取与识别,从而获得车辆的结构化信息,在对检本图像提取的特征模型和样本图像特征模型进行匹配时,可通过快速最邻近搜索算法搜索高相似度图片,从而实现以图搜图,并方便对其进行对比取证,进而形成固定证据链。
