The invention relates to a road shooting method. The method comprises the following steps: acquiring an image coverage distance of a vehicle-mounted camera; obtaining a first sampling time interval of the vehicle-mounted camera according to the image coverage distance, and obtaining the current vehicle speed through the vehicle-mounted camera and the OBD bus; calculating a vehicle driving distance according to the first sampling time interval and the current vehicle speed; positioning data and distance correction parameters of the RTK positioning device are obtained according to the first sampling time interval, and the vehicle driving distance is corrected according to the distance correction parameters; and correcting the first sampling time interval according to the image coverage distance, the current vehicle speed and the vehicle driving distance to obtain a second sampling time interval, and shooting the road within the second sampling time interval. Compared with the prior art, the method has the advantages of high shooting precision and the like.
本发明涉及一种道路拍摄方法,包括获取车载相机摄像头的图像覆盖距离;根据图像覆盖距离获取车载相机的第一采样时间间隔,并通过车载相机和OBD总线,获取当前车速;根据第一采样时间间隔和当前车速计算车辆行驶距离;根据第一采样时间间隔获取RTK定位装置的定位数据和距离修正参数,并根据距离修正参数修正车辆行驶距离;根据图像覆盖距离、当前车速和车辆行驶距离修正第一采样时间间隔,得到第二采样时间间隔,在第二采样时间间隔内对道路进行拍摄。与现有技术相比,本发明具有拍摄精度高等优点。
