The invention provides an accurate evidence obtaining method for long-distance illegal parking of an expressway emergency lane, which can realize accurate evidence obtaining of vehicles which are parked illegally in a long distance by utilizing existing equipment, and is low in cost, short in time consumption and high in practicability. The usability of an image which is shot by a dome camera and is used for extracting a feature vector is ensured through quality judgment operation, the difficulty of verification feature value extraction is reduced, the overall calculation speed is increased, and the accuracy of a final calculation result is improved; identifying the illegal parking behavior of the long-distance emergency lane through a gunlock, and analyzing the ReID characteristics of the vehicle; the method comprises the following steps: firstly, carrying out camera shooting on the vehicle, then linking a ball machine to close, analyzing the ReID characteristics of the vehicle in a picture, and meanwhile, comparing the ReID characteristics of the vehicle of the gun camera and the ball machine to accurately judge whether the vehicles captured twice are the same vehicle which is illegally parked on the emergency lane of the expressway or not, so as to finish the accurate evidence collection of the illegal parking behavior on the long-distance emergency lane.
本发明提供一种高速公路应急车道远距离违法停车的精准取证方法,其可以利用现有设备实现对远距离违法停车的车辆进行精准取证,成本低、费时短,实用性强。其通过质量判断操作来确保球机拍摄的用来提取特征向量的图像的可用性,降低验证特征值提取的难度,提高整体计算速度,以及提高最终计算结果的准确性;通过枪机识别远距离应急车道违法停车行为,并解析车辆ReID特征;然后联动球机进行拉近,并解析画面内车辆ReID特征,同时通过比对枪机与球机的车辆ReID特征,能准确判断两次抓拍的车辆是否为同一辆发生高速公路应急车道违法停车的车辆,进而完成对远距离应急车道违法停车行为的精准取证。
