摘要
This paper describes a novel method for determining the absolute orientation of lidar point clouds using GPS measurements from two antennas firmly mounted on the optical head of a lidar scanner. The solution is linear and is derived from the non-linear georeferencing model by exploiting the properties of the skew-symmetric matrix. Simulation and real world experimentation using our prototype suggest a precision of about 0.05 degrees (similar to 1 mrad) for the three Euler attitude angles. The method can help alleviate problems associated with the conventional technique and can allow for an increased number of practical applications for georeferenced terrestrial lidar.
