Abstract

To solve the problem that plantar point cloud cannot be directly obtained in the digital twin foot model building system which simultaneously collect the 3D point cloud of foot and plantar pressure distribution data, a plantar point cloud repair method based on plantar pressure distribution data is proposed in this paper. First of all, the contour points of the foot point cloud and the plantar pressure distribution data are extracted, and then the two contours are matched by searching the optimal rotation and translation transformation, secondly, the plantar pressure distribution data is smoothed by using the mean and gaussian filters, then on the basis of the contour of the foot point cloud clipped the plantar pressure distribution data, finally, the plantar point cloud is optimized by constructing a mapping function to convert plantar pressure data into the height value of the plantar point cloud. Experimental results show that the proposed method is significantly better than the planar repair method.
