Problems solved by technology

[0003] However, most of the existing shoe last model reverse reconstruction file formats are point cloud models and NURBS surface models generated by the boundary blending method or facet feature method. Multiple redundant points, large storage space, difficult data management and analysis, which is not conducive to real-time processing of models

Abstract

The invention relates to an image reconstruction method, which comprises the following steps: shooting a group of two-dimensional images around a foot or shooting a complete video around the foot by using a mobile shooting device; performing grayscale processing on the uploaded image; determining feature points in each of the images varying in resolution by forming an image resolution pyramid; performing Gaussian blur at different scales to the images, and sampling the smooth images in a downsampling mode which means that the resolution decreases layer by layer; building a Gaussian pyramid anda Gaussian difference pyramid, wherein in each layer of the pyramids, the position representing the Harris angle feature of the images is determined; finding the position of each corner feature, displaying the angular strength, according to the comparison between the angular strength and the predetermined minimum strength threshold, deleting the points, repeating the tests, determine whether thetotal exceeds the maximum permitted value, if so, increasing the radius again and repeating the process, and alternately performing the operations until the number of corner positions equals or decreases to the maximum permitted value.

Description

technical field [0001] The invention relates to a shoe last model construction technology, in particular to a processing method and system for reconstructing a triangular mesh model of a foot. Background technique [0002] The human foot is prone to deformation and difficult to be in a static state. If the point cloud data of the foot is obtained using a contact measuring device, the probe of the measuring device will squeeze the instep during the measurement process, deforming the shape of the human foot. When the human foot is damaged, it also causes some errors in the measured human foot point cloud. Moreover, the use of contact measurement equipment requires the human foot to be in a specific position all the time, and the device needs to be used to fix it on the workbench. When measuring, the human foot also needs to move with the workbench. It is difficult for the human foot to achieve these requirements. As a result, many foot feature parameters and some complex surf...
