Reliable and Rapidly-Converging ICP Algorithm Using Multiresolution Smoothing
Autonomous range acquisition for 3D modeling requires reliable range registration, for both the precise localization of the sensor and combining the data from multiple scans for view-planning computation. We introduce and present a novel approach to improve the reliability and robustness of the ICP (Iterative Closest Point) 3D shape registration algorithm by smoothing the shape’s surface into multiple resolutions. These smoothed surfaces are used in place of the original surface in a coarse-to-fine manner during registration, which allows the algorithm to avoid being trapped at local minima close to the global optimal solution. We used the technique of multiresolution analysis to create the smoothed surfaces efficiently. Besides being more robust, convergence is generally much faster, especially when combined with the point-to-plane error metric of Chen and Medioni. Since the point-to-plane error metric has no closedform solution, solving it can be slow. We introduce a variant of th...
