The invention discloses a camera license plate recognition accuracy detection method and system, computer equipment and a storage medium. The method comprises the following steps: acquiring a first license plate data set acquired by ETC roadside equipment and a second license plate data set recognized by a camera within a detection time period; counting the number of license plates at the intersection of the first license plate data set and the second license plate data set; and according to the ratio of the number of the intersection license plates to the number of license plates in the first license plate data set, calculating the license plate recognition accuracy of the camera. According to the camera license plate recognition accuracy detection method based on the ETC license plate data, the credible ETC license plate data and the camera license plate recognition result are used, and the camera license plate recognition accuracy with high credibility can be calculated according to a designed statistical algorithm.

    本发明公开了摄像机车牌识别正确率检测方法、系统、计算机设备及存储介质,该方法包括以下步骤:获取检测时间段内ETC路侧设备获取到的第一车牌数据集以及摄像机识别到的第二车牌数据集;统计第一车牌数据集和第二车牌数据集交集的车牌数量;根据交集的车牌数量与第一车牌数据集中的车牌数量的比值,计算摄像机识别车牌的正确率。本发明提出了基于ETC车牌数据的摄像机车牌识别正确率检测方法,使用可信的ETC车牌数据和摄像机车牌识别结果,并根据设计的统计算法,可以计算出可信度高的摄像机车牌识别正确率。
