Noncontact three-dimensional laser foot type measuring system and method

Abstract

The invention discloses a noncontact three-dimensional laser foot type measuring system and method. The system comprises an object-carrying glass platform, a mechanical supporting module, an optical imaging module, a movement control module, a three-dimensional model building module, an automatic parameter measuring module and a 3D shoe tree designing module. A user only needs to place a measured foot on the object-carrying glass platform, then omnibearing three-dimensional data measuring can be completed through the optical imaging module, and high-density three-dimensional surface shape point cloud data are acquired; feature parameters of foot type are given through the automatic parameter measuring module, whether the foot type is malformed or not is judged according to the high-density three-dimensional surface shape point cloud data and the feature parameters, shoe tree designing is performed, and complete measuring of one foot type can be completed within ten seconds or more; noncontact laser measuring is adopted, and the user can perform measuring under a condition of easily stretching, so that deformation caused by contact is avoided effectively; the movement control module controls the optical imaging module to move back and forth for measuring, so that the acquired three-dimensional surface shape point cloud data are more omnibearing and higher in density.

Description

technical field [0001] The invention relates to the field of shoemaking, in particular to a non-contact three-dimensional laser foot shape measurement system and measurement method. Background technique [0002] In the shoemaking industry, the shoe last, which is the mother of shoes, must be designed based on the shape of the foot. In the field of health care, it is often necessary to obtain data on the shape of a person's foot. At present, the measurement of foot shape is mostly obtained by experienced shoemakers using a tape measure and a height measuring device. The customer experience is not good, and the accuracy of the data is greatly affected by human factors. At the same time, it is not convenient for large-scale measurement. The measured data Lack of complete 3D surface data; [0003] With the development of computer vision technology, the use of automated intelligent machine measurement will bring greater convenience. According to the measurement method, it is...
