By adopting different reconstruction techniques, 3D sensors generate different point clouds of various scales for the same object. This paper presents a new algorithm to align point clouds of different scales. First, shape descriptors based on different neighboring sizes are calculated on each point. Secondly, for each neighboring size, principle components analysis is applied on all descriptors to...
Two point clouds of the same scene reconstructed by different techniques may differ in scale. A new scale registration algorithm is proposed in the paper to find the scale difference between two point clouds. First, principle components analysis is applied on descriptors of the point cloud to derive different cumulative contribution rates (CCR) in different neighbor regions. The discrete CCR of each...
