The invention relates to a
processing method and a
system for reconstructing a foot
point cloud model. The method comprises the following steps: obtaining a
point cloud three-dimensional model reconstructed by matching a plurality of two-dimensional images; firstly, the 3D model of
point cloud being divided into pieces by using the method of spatial hierarchical partition, and a simplified representation being calculated for each piece to obtain a simplified point cloud model; using the chord
height difference method, connecting the front and back points of the detection point, calculating thedistance between the intermediate
data point and the chord, comparing the distance with the given tolerance value, if the distance is greater than the tolerance value, determining that it is an abnormal point, and then deleting it, so as to remove the
noise point in the place where the density is high and the curvature changes greatly in the point cloud model; then the weighted
median filter being used to eliminate burrs and smooth the model; by calculating the length of each side of the uniform hole boundary, according to the calculated size of each included angle, the filling point coordinates being calculated, and the illegal judgment points falling outside the hole area being removed; repeating the process until a new filling point cannot be calculated and the hole filling ends.
