The invention provides a method for reducing license plate false identification and improving identification precision. The method comprises the following steps of S1, starting a spherical camera, andenabling the spherical camera to enter a working state, S2, presetting an illegal parking monitoring area of the spherical camera, S3, acquiring an image of the monitoring area, and detecting vehicles in the parking forbidding area, S4, calculating two-dimensional coordinates of the vehicle through an identification algorithm, S5, obtaining three-dimensional coordinates of the vehicle through three-dimensional conversion, S6, after the three-dimensional coordinates are obtained, adjusting the vehicle to the center of the picture, S7, performing three-dimensional conversion on the two-dimensional coordinates of the vehicle again to obtain coordinates of an identification area, and identifying the vehicle, and S8, acquiring license plate information of the identified vehicle through an identification algorithm. According to the method for reducing license plate false identification and improving identification precision, the problems that the number of invalid pictures is too large andthe false identification rate is high due to the fact that vehicle pictures cannot be accurately obtained through an existing license plate identification function for collecting illegal parking evidences are solved.

    本发明提供了一种降低车牌误识别和提高识别精度的方法,包括以下步骤:S1:开启球形摄像机,使球形摄像机进入工作状态;S2:预先设定球形摄像机的违法停车监测区域;S3:获取监测区域图像,检测出禁止停车区域内的车辆;S4:通过识别算法计算出车辆的二维坐标;S5:通过三维转换得到车辆的三维坐标;S6:得到三维坐标以后将车辆调整至画面中心;S7:将车辆二维坐标再次进行三维转换得到识别区域坐标,对车辆进行识别;S8:通过识别算法对识别到的车辆获取车牌信息。本发明所述的一种降低车牌误识别和提高识别精度的方法解决了现有的采集违法停车证据车牌识别功能由于无法精准的获取车辆图片,造成无效图片过多,误识别率较大的问题。
