The study presents a method for registration of terrestrial light detection and ranging point clouds based on geometric features (GFs) without using targets. It aims to solve the rotation and translation between two data sets using geometric features, including points, lines, planes, and cylinders. Conjugate planes are used to solve the rotation and the intersected points of the axes of the cylinders and planes are used as conjugate points to solve the translation. Based on the result from an experiment, it has been demonstrated that the proposed approach is capable of giving a reliable and satisfactory registration solution.
