WebJul 1, 2024 · A novel 3D descriptor named Histograms of Local Point Pair Features (HoPPF) is proposed. • • Three modules for HoPPF, including data preprocessing, local point pair set division, distribution matrix generation are proposed. • • Accurate recognition results on real datasets validate that the HoPPF can be applied to 3D vision. Abstract WebAug 18, 2009 · Fast Point Feature Histograms (FPFH) for 3D registration Abstract: In our recent work [1], [2], we proposed Point Feature Histograms (PFH) as robust multi …
WebMay 12, 2009 · In our recent work [1], [2], we proposed Point Feature Histograms (PFH) as robust multi-dimensional features which describe the local geometry around a point p for 3D point cloud datasets. In this paper, we modify their mathematical expressions and perform a rigorous analysis on their robustness and complexity for the problem of 3D registration ... WebApr 12, 2024 · However, higher computational complexity makes PFH unsuitable for real-time applications. Therefore, Fast Point Feature Histogram (FPFH) (Rusu et al. 2009, 2009) is proposed to solve this problem. It consists of two steps. The first step is the construction of the Simplified Point Feature Histogram (SPFH).
