Multi-view imaging device of foot type three-dimensional reconfiguration

Abstract

The invention relates to a multi-view imaging device for three-dimensional reconstruction of foot shape, including a foot shape calibration template with a load-bearing function, a camera support frame, at least six cameras, and a computer. The foot shape calibration template is arranged in the camera support frame through a bracket, The at least six cameras are marked towards the center of the foot type calibration template, and the at least six cameras are connected to the computer through the USB data transmission interface, and the collected digital images are three-dimensionally reconstructed by a software system running on the computer, with imaging It has the characteristics of low cost, simple installation, accurate imaging, and fast 3D reconstruction.

Description

technical field [0001] The invention relates to an imaging device, in particular to a multi-view imaging device for three-dimensional reconstruction of foot shape. Background technique [0002] Calibration is a very important step in the process of 3D reconstruction of objects. The calibration method in the prior art needs to place an object of known shape and size (called a calibration reference object) in front of the camera, and calculate the position of the camera. Then remove the calibration reference object, and then take a picture of the object that needs 3D reconstruction, and perform 3D reconstruction through the corresponding relationship between the spatial point and the image point. Zhang Zhengyou of Microsoft Research uses two to three mutually orthogonal planes to form a calibration template as a calibration reference object, which is widely accepted because it is simple and practical. However, Zhang Zhengyou’s method needs to image the calibration reference ob...

Zhang Zhengyou of Microsoft Research uses two to three mutually orthogonal planes to form a calibration template as a calibration reference object, which is widely accepted because it is simple and practical. However, Zhang Zhengyou’s method needs to image the calibration reference object first, and then remove the calibration reference object again For object imaging, calibration imaging and reconstruction imaging are divided into two steps; and due to the use of opaque calibration templates, it cannot be applied to multi-view reconstruction of full-circle multi-directional imaging; the research object of the present invention is feet, which need to be placed on On a certain support, the support will inevitably affect the image acquisition of the soles of the feet, and Zhang Zhengyou’s calibration method is not applicable; if the feet are suspended in the air for imaging, there must be shaking problems, which will affect the imaging effect
