Abstract

The invention relates to the field of stereoscopic scanning and discloses a foot scanner calibration method and device; in an embodiment of the invention, the foot scanner calibration method comprises: acquiring an image including the calibration device; segmenting the image according to a preset segmenting manner to obtain N image blocks, with N being a natural number greater than 1; analyzing brightness of each of the N images to obtain respective high-brightness areas of the N images; using the N high-brightness areas as calibration points. The embodiment of the invention also discloses a foot scanner calibration device. By using the foot scanner calibration method and device according to the embodiment of the invention, a foot scanner can be calibrated automatically, the automation level of calibration steps is increased, and calibration efficiency and accuracy can also be improved.

Description

technical field [0001] The invention relates to the field of three-dimensional scanning, in particular to a calibration method and device for a foot scanner. Background technique [0002] With the development of society, people pay more and more attention to their quality of life, and their requirements for shoes are increasing day by day. It costs a lot to go to a traditional custom shop to customize shoes, and it is often the case that the shoes are not suitable when you go to a store or online to buy the shoes. With the development of science and technology, foot scanners that are more suitable for general consumers have appeared. At present, in the process of professionally customizing shoes, the three-dimensional data of the foot is measured by a three-dimensional foot scanner, and the measured data is more accurate. The shoes customized according to the measured three-dimensional data are more suitable and comfortable. [0003] The inventors of the present applicati...
