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 a reconstruction shoe tree model detecting method and system. The method comprises the following steps of calculating the distance and angle between corresponding points of aconstructed shoe tree model detected by a foot model, and setting the maximum detection distance and the maximum angle; comparing the calculated distance and angle with a set allowance error value, and measuring a maximum positive normal deviation and a maximum negative normal deviation; evaluating the local error distribution uniformity, wherein if the calculated maximum value is smaller than theset allowance value, it is shown that the produced shoe tree meets the requirement; otherwise, the produced shoe tree needs to be modified till the shoe tree meeting the requirement is produced. Thesystem comprises a calculating unit, a comparing unit and a detecting unit.

Description

technical field [0001] The invention relates to shoe last model construction technology, in particular to a reconfigured shoe last model detection method and system. 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 surfaces and curves cannot be m...
