Abstract
Mobile LiDAR systems have been widely used in collecting 3D spatial information due to its high efficiency. However, its positioning quality relies on a good reception of GNSS signals. Therefore, point clouds positioning error accumulates with time when GNSS signal is obstructed. This study presents a fully automatic intensity-based multi-epoch mobile LiDAR point clouds matching and adjustment procedure. The experiment results indicated that the proposed frameworks can provide accurate and sufficient features for the adaptive time-variant adjustment and help to improve the positioning quality for the LiDAR point clouds acquired in a GNSS signal obstructed area. Consequently, the mobile LiDAR systems can be extended to a wider field of applications.
