A marker-free method for registering multi-scan terrestrial laser scanning data in forest environments
ISPRS Journal of Photogrammetry and Remote Sensing(2020)
Abstract
•A novel marker-free multi-scan TLS registration method is proposed.•It uses the occlusion effect of tree trunks in TLS scans as the key features.•It does not require processing steps to extract individual tree attributes.•The proposed method is tested in plots with different vegetation conditions.•Its registration accuracy is equivalent to the manual registration method.
