Three-dimensional foot scanner

Abstract

The invention relates to a three-dimensional foot scanner which can form images or three-dimensional data records of feet of human bodies and is used for the manufacturing shoe trees. The three-dimensional foot scanner comprises a foot scanning device and a foot image analysis system, wherein the foot scanning device is used for shooting a medial border image, a lateral border image and a sole image of a foot; and the foot image analysis system is used for analyzing the medial border image, the lateral border image and the sole image of the foot so as to acquire three-dimensional foot data. In the three-dimensional foot scanner, the medial border image, the lateral border image and the sole image of the foot are shot by a plurality of cameras, the images are corrected and spliced, integrated outlines of the medial border, the lateral border and the sole of the foot are extracted, and standard three-dimensional foot data is combined so as to generate a foot three-dimensional model. By using the three-dimensional foot scanner, the scanning time and production cost are greatly reduced on the premise of ensuring certain precision.

Description

technical field [0001] The invention relates to a three-dimensional foot scanner, in particular to a three-dimensional foot scanner involving photography, which can form images or three-dimensional data records of human feet for making shoe lasts. Background technique [0002] Footwear industry is a traditional labor-intensive industry. However, with the rapid development of science and technology, especially the rapid development of computer-aided design and mechanical automation, the shoemaking industry has changed from traditional handicrafts to modern computer-aided and mechanized automatic shoemaking. Software and machines such as shoe pattern design software, shoe last design software, 3D laser scanners and automatic shoe last machines have been widely used. [0003] In the entire footwear automation design and manufacturing process, the use of foot scanners to obtain three-dimensional information of human feet is a crucial link. Only by obtaining the three-dimension...
