Problems solved by technology
However, due to the dynamic changes of GPS signal quality and inertial navigation drift in point cloud and image registration in vehicle-mounted MMS, there are various sources of registration errors. Fully automatic registration technology is still in the research stage for the time being, and has not yet reached mass production application. s level
However, using the calibration field to calibrate after a period of time, this type of semi-automatic registration method will bring more additional burden to the field collection, and it is difficult to implement

Embodiments of the present invention provide a method and system for registering a laser point cloud and an image. The method includes: randomly extracting random data of a preset number of frames from the data to be registered, and for each frame of random data, randomly After the point cloud image in the data is adjusted to be consistent with the camera image, the adjustment parameters are saved; the adjustment parameters corresponding to the random data of the preset number of frames are analyzed to obtain the correlation between the adjustment parameters and the inertial navigation attitude; according to the correlation The point cloud image and the camera image in each frame of data to be registered are registered. In the embodiment of the present invention, semi-automatic parameter adjustment is performed on the data of the sampled part of the frame, and then the parameter adjustment is applied to the whole data, which can achieve higher precision and reduce the cost of all parameter adjustment.
Description
technical field [0001] The present invention relates to the field of mobile measurement, and more particularly, to a method and system for registering a laser point cloud and an image. Background technique [0002] At present, mobile measurement technology has become one of the main technologies for obtaining high-precision navigation electronic map data. Mobile Mapping System (MMS) is a vehicle equipped with sensors and equipment such as GPS (Global Positioning System), CCD (Video System), INS (Inertial Navigation System) or dead reckoning system. During the process, the spatial location and attribute data of the road and roadside features are quickly collected, such as: road surface, lane printing lines, road indicating arrows, crosswalks, traffic signs, traffic lights, etc. The data will be stored in the on-board computer system synchronously, and after various software processing, various result data will be formed, which will be used for the production of navigation el...
