Point clouds have ability to express the spatial entities, however, the point clouds redundancy always involvessome uncertainties in computer recognition and model construction. Therefore, point clouds thinning is an indispensablestep in point clouds model reconstruction and other applications. To overcome the shortcomingsof complex classification index and long time consuming in existing point clouds thinning algorithms, thispaper proposes a point clouds fast thinning algorithm. Specifically, the two-dimensional index is established inplane linear array (x, y) for the scanned point clouds, and the thresholds of adjacent point distance differenceand height difference are employed to further delete or retain the selected sample point. Sequentially, the indexof sample point is traversed forwardly and backwardly until the process of point clouds thinning is completed. The results suggest that the proposed new algorithm can be applied to different targets when the thresholds arebuilt in advance. Besides, the new method also performs superiority in time consuming, modelling accuracyand feature retention by comparing with octree thinning algorithm.
