Problems solved by technology

[0007] Existing solutions cannot solve the 3D reconstruction of non-rigid bodies, that is to say, the existing solutions require the reconstructed object or scene to be immobile (during the scanning process)

Embodiment Construction

[0061] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0062] Such as figure 1 Shown, be a kind of digitalized human body three-dimensional reconstruction method based on Kinect device described in specific embodiment 1 of the present invention, specifically comprise the following steps:

[0063] Step 1: Scan to obtain surface feature data;

[0064] Step 2: Perform denoising preprocessing on the surface feature data to obtain smooth depth information without noise;

[0065] Step 3: Perform rigid body matching and non-rigid body matching on the depth information in sequence to obtain a 3D model.

[0066] In the step 2, an auxiliary filter is used to denoise the noise points in the surface feature data to obtain the depth information in the local coordinate system.

Abstract

The invention relates to a digital human body three-dimensional reconstruction method based on a Kinect device. The method specifically includes the following steps that firstly, scanning is performed, and surface feature data are obtained; secondly, denoising preprocessing is performed on the surface feature data, and smooth depth information without noise is obtained; thirdly, rigid-body matching and non-rigid-body matching are sequentially performed on the depth information, and a three-dimensional model is obtained. According to the digital human body three-dimensional reconstruction method, the scanning time is short, the scanning process is simple, a hardware device needed in scanning is simple, coordination with other people or instructions learning in advance are not needed in the scanning process, the result geometric accuracy is high, the face structure, the clothes texture structure and the like are quite clear, due to a test, the system stability is high, a one-button mode is adopted in a whole system, a user does not need to set any parameter or change, a final result can be obtained as long as one button is pressed, the operation time is short, and a color map is automatically generated.

Description

technical field [0001] The invention relates to a method and system for digital three-dimensional reconstruction of a human body based on a Kinect device. Background technique [0002] Kinect is a 360-degree dynamic tracking and scanning peripheral auxiliary device developed by Microsoft for XBox in 2010. The front end of the Kinect device consists of a camera and two cameras. The camera is an infrared emitter. After obtaining the infrared data from the infrared camera, it calculates and processes it internally, and then generates depth data. Kinect is actually a 3D somatosensory camera, which uses functions such as real-time motion capture, image recognition, microphone input, voice recognition, and community interaction to allow players to get rid of the shackles of traditional gamepads, control the game through their own body, and realize communication with Internet players. Interact and share pictures, audio and video information. The price of Kinect is only more than...
