Embodiment

[0080] See figure 1 , figure 1 It is a flow chart of the three-dimensional human body modeling method based on a single Kinect proposed in this embodiment. figure 1 The shown three-dimensional human body modeling method based on a single Kinect comprises four steps:

[0081] S1. Use Kinect to scan the human body, extract the point cloud, and obtain the color and depth data of the human body. Analyze the obtained data and perform data segmentation to remove the background.

[0082] S2. Perform local alignment of the point cloud data of the human body. The three point clouds for each angle are aligned using rigid registration and then merged into one point cloud.

[0083] S3. Perform global alignment of human body point cloud data, including initial registration, rigid registration and non-rigid registration.

[0084] Initial registration, optimize the initial position, and provide a better initial state for the next step of alignment.

[0085] Rigid registration, using ri...

Abstract

The invention discloses a simple and high-efficient three-dimensional human body reconstruction method based on a single Kinect. The three-dimensional human body reconstruction method comprises the following steps of 1) acquiring point cloud; 2) carrying out point cloud pretreatment; 3) carrying out local aligning; 4) carrying out global aligning; and 5) carrying out surface reconstruction. A user can easily realize three-dimensional human body modeling in a narrow space, such as a home room or an office room, and only a personal computer and a Kinect are needed. In order to make the human body modeling become rapid, accurate and convenient, the invention provides an effective whole body scanning data acquisition strategy. Through six angles, three frame scanning is performed for each angle so that the human body can be completely covered. Point cloud data processing captured by the Kinect includes two steps of the local aligning and the global aligning. The new three dimensional human body modeling method can be suitable for most of applications, such as digital measurement, a product design and on-line shopping.

Description

technical field [0001] The invention relates to the technical field of three-dimensional human body modeling, in particular to a simple and efficient three-dimensional human body reconstruction method based on a single Kinect. Background technique [0002] The rapid modeling technology of 3D objects is one of the important research topics in the field of computer graphics, and the rapid modeling technology of 3D objects is the development trend of rapid reconstruction of object models. 3D object reconstruction can be made cheaper, and 3D models are as readily available as photos and videos. This technique is used in many computer graphics applications, such as animation, computer games, human-computer interaction, and virtual reality, that require accurate 3D models. Such as e-commerce website platform, online shopping website, game field, etc. [0003] RGB-D cameras are an emerging scanning device. RGB-D cameras combine the advantages of optical cameras and 3D laser scan...
