Problems solved by technology

[0003] At present, commercial human body scanning systems appearing at home and abroad generally apply the principles of structured light and laser scanning for static scanning of the human body. When scanning structured light, it is generally necessary to project more than a dozen grating patterns to the human body, while when scanning lasers, The laser light strip needs to move in a certain direction until the strip sweeps the whole body area. Therefore, the common defects of these two methods are: the cost of equipment is expensive, the scanning takes a long time, and the human body will inevitably shake during standing, which will lead to poor scanning accuracy. poor

Embodiment Construction

[0021] The following embodiments illustrate the three-dimensional human body method in the present disclosure with reference to the accompanying drawings.

[0022] In one embodiment, figure 1 The measurement device deployment is illustrated. Through 3 depth cameras fixed on a single column, the rotating human body depth and color images are collected in real time. The measuring platform is used for standing people, and the measuring platform can be rotated to realize 360-degree scanning, and its rotation speed can be controlled by computer. The computer controls 3 depth cameras to collect human body depth images and color images in real time, and controls the transmission speed of the images, such as 30 frames per second. A set of supplementary light is arranged on both sides of a single column to adjust the brightness of the supplementary light according to the site environment.

[0023] Here, the depth camera is preferably a Kinect camera, and its structure is as follows ...

Abstract

The invention relates to a human body three-dimensional scanning method. The method comprises the steps of converting depth image data into point cloud data; performing filtering, registration and fusion on the point cloud data; and building a human body three-dimensional model. According to the method, the conversion operation of converting the depth data into the point cloud data, and the filtering, registration and fusion of the point cloud data can be executed in parallel, real-time registration and point cloud fusion can be realized, and errors caused by shake of a human body can be eliminated, so that the precision of human body three-dimensional modeling is improved.

Description

technical field [0001] The present disclosure relates to three-dimensional data measurement of a human body in the field of three-dimensional measurement, and in particular, relates to a three-dimensional scanning method of a human body. Background technique [0002] 3D human body scanning obtains the 3D model and body size of the human body through optical measurement, and is widely used in 3D printing, game animation production, personalized customization, and medical research. For example, when using 3D printing technology to print a human body model, it is necessary to obtain human body data through human body scanning in advance; in terms of game animation production, the real human body model obtained by human body scanning increases the interest and visibility of games or animations; in addition, With the improvement of people's living standards, personalized customization has become the development trend of the clothing industry. By scanning the human body and automa...
