Introduction Terrestrial Light Detection and Ranging (Lidar) generates 3D coordinates of an object point by measuring the horizontal and vertical angle and the distance between the scanner's centre and the object point. Due to its ability to provide dense, fast and accurate measurements, the use ...
The amount of point clouds data provided by laser scanning systems is extremely large, composed of (x, y, z) coordinates and additional information such as intensity, Global Positioning System (GPS) time, or the scanning angle of millions of points. The analysis and processing of these data ...
The ||·|| denotes the Euclidean distance between the interpolation point and each sample point, i.e., ri = (x − xi)2 + (y − yi)2, and a0, a1, a2 are the coefficients of the planar term of the spline. Therefore, TPS interpolation contains two steps, i.e., coefficient ...
