Abstract

The embodiment of the invention provides a data processing method and a data processing device, wherein the method comprises the following steps: obtaining an original mobile measuring track and original point cloud data and aerial photo point cloud data corresponding to the original mobile measuring track; calibrating the original point cloud data by adopting the aerial photo point cloud data to obtain excursion information of the original point cloud data; calculating correcting information of the original mobile measuring track according to the excursion information of the original point cloud data; correcting the original mobile measuring track by adopting the correcting information to obtain a target mobile measuring track; generating target point cloud data according to the target mobile measuring track. The data processing method can enable the point cloud data to have description of measuring details, guarantees the measuring precision and improves the data processing effectiveness and accuracy.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a data processing method and device. Background technique [0002] With the development of Internet technology, in order to meet people's urgent needs for three-dimensional maps and three-dimensional navigation, mobile measurement systems have developed rapidly, and the processing of mobile measurement data has become an important research topic. The vehicle-mounted mobile measurement system is the most widely used at present. It uses ground mobile tools such as trains and automobiles as the carrier platform. By scanning the road and the surface of the building when the mobile carrier is moving, the mobile measurement track can be obtained and the corresponding points can be generated. Cloud data; vehicle-mounted mobile measurement systems can usually measure the details of the ground environment, but its mobile measurement trajectory is prone to drift, so the accuracy of th...
