Problems solved by technology

[0003] At present, commercial human body scanning systems have appeared at home and abroad. These systems are generally based on the principle of grating, infrared or laser scanning, and are mainly used for three-dimensional static scanning of the human body. The common defect is that one scan requires multiple projections of gratings or laser stripes. , making the overall scanning speed slower, and it is difficult to avoid errors caused by human body shaking

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] In one embodiment, such as figure 1 As described in the flow chart: the present invention discloses a three-dimensional rapid scanning method of digital speckle human body;

[0025] The method comprises the steps of:

[0026] S100, multi-camera global calibration: arrange calibration boards in the measurement field of view to calibrate the internal parameters and external parameters of the cameras in multiple measuring heads;

[0027] S200. Rapid collection of human body images: using multiple measuring heads to project random speckle patterns to different positions on the human body surface, and using multiple measuring heads to simultaneously collect human body images from different angles;

[0028] S300. Human body three-dimensional point cloud reconstruction: based on steps S100 and S200, perform stereo matching and three...

Abstract

The invention discloses a digital-speckle three-dimensional quick scanning method of a human body. The method projects a random speckle pattern to a human body surface, adopts multiple cameras to shoot a human body image and carries out relevant analysis on the human body image to realize the quick scanning of three-dimensional data of the human body. The method comprises the following steps: 1) carrying out multi-camera global calibration; 2) quickly collecting the human body image; 3) carrying out the three-dimensional point cloud reconstruction of the human body; 4) carrying out multiple-frame point cloud registration; and 5) carrying out the three-dimensional modeling of the human body. Through the above operation steps, the invention provides a quick scanning method of the three-dimensional data of the human body and has the advantages of being convenient in operation, quick in scanning and colorful in scanning.

Description

technical field [0001] The invention relates to the problem of three-dimensional data measurement of a human body in the field of three-dimensional measurement, in particular to a fast three-dimensional scanning method of a digital speckle human body. Background technique [0002] Three-dimensional measurement of the human body studies the morphological characteristics of the human body by obtaining the size and model of each part of the human body, and is widely used in 3D printing, medical treatment, clothing customization, motion analysis and other fields. For example, when performing 3D printing of a real-life model, the first thing to do is to obtain the 3D data of the human body; and in terms of medical treatment, quickly obtaining the 3D data of the human face is a prerequisite for formulating better plastic and orthopedic surgery plans; Quality requirements are getting higher and higher, and the designed daily-use products must match the size of the human body more c...
