Description

technical field [0001] The invention relates to the technical field of high-precision measurement of catenary, in particular to a high-precision automatic measurement device and method for interaction between laser radar and range finder. Background technique [0002] At present, in the measurement of catenary, single-line or multi-line lidar can obtain a large number of point clouds at high speed, and the coordinate information data of tens of thousands or even millions of points per second, but the coordinates of these points often exist in length or angle. Larger errors, and even the use of high-precision lidar will have the problem of large length and angle errors. On the other hand, the accuracy of ±2mm or ±1mm cannot be achieved even if the laser radar with better error stability is used alone. Although it can be achieved with the laser rangefinder, it is limited to manual single-point measurement, resulting in poor efficiency. [0003] The invention realizes a set of...
