The invention relates to a road shooting method and system based on a vehicle OBD, and the method comprises the following steps: S1, obtaining the vehicle-mounted camera data of a vehicle, and obtaining the image coverage distance of a vehicle-mounted camera based on the vehicle-mounted camera data; s2, acquiring an initial sampling time interval, and acquiring vehicle speed data in shutter data and OBD data of a vehicle-mounted camera of the vehicle based on the initial sampling time interval; s3, correcting the vehicle speed data; s4, acquiring a vehicle driving distance between the two shutter data based on the corrected vehicle speed data; and S5, comparing the vehicle driving distance with the image coverage distance, correcting the initial sampling time interval based on a comparison result, obtaining a corrected time interval, and shooting the road based on the corrected time interval. Compared with the prior art, the method can effectively avoid the phenomenon of leak detection caused by too high vehicle speed, can reduce the slow sampling frequency in a low-speed state, and avoids the accumulation of a large amount of repeated data.
本发明涉及一种基于车辆OBD的道路拍摄方法及系统,所述方法包括以下步骤:S1:获取车辆的车载相机数据,基于所述车载相机数据获取车载相机的图像覆盖距离;S2:获取初始采样时间间隔,基于初始采样时间间隔获取所述车辆的车载相机的快门数据、OBD数据中的车速数据;S3:对车速数据进行修正;S4:基于修正后的车速数据获取两次快门数据间的车辆行驶距离;S5:将车辆行驶距离和所述图像覆盖距离进行对比,并基于比对结果对初始采样时间间隔进行修正,获取修正时间间隔,基于修正时间间隔对道路进行拍摄。与现有技术相比,本发明可以有效避免因车速过快而产生漏检的现象,可以在低速状态下降缓采样频率,避免重复数据大量累积。
