Embodiment Construction

[0032] Such as figure 1 As shown, the present invention discloses a method for establishing a human body model based on a depth sensor, comprising the steps of:

[0033] S1. Select the basic model, and then the user stands in front of the depth sensor in the collection orientation to complete the collection of human body parameters, the human body parameters include bone data and depth data;

[0034] S2. Smoothing the obtained human body parameters by using the Kalman filter algorithm;

[0035] S3. Obtain a real-time reconstruction algorithm based on the basic model and human body parameters;

[0036] S4. According to the body parameters required in the basic model, manually measure the body parameters offline, combine the body parameters and real-time reconstruction algorithm, calculate the weight parameters of each part in the basic model, and then combine the weight parameters and human body parameters to establish based on the basic model mannequin.

[0037] The basic m...

Abstract

The invention discloses a human body modeling method based on a depth sensor. The method comprises the following steps: S1, selecting a basic model, and then a user standing in front of the depth sensor with an acquisition azimuth to complete human body parameter acquisition, wherein the human body parameter comprises bone data and depth data; S2, smoothing the obtained human body parameters by using the Kalman filter algorithm; S3, obtaining a real-time reconstruction algorithm according to that basic model and the human body parameter; S4, according to the body parameters needed in the basicmodel, measuring the body parameters off-line manually, calculating the weight parameters of each part in the basic model by combining the body parameters and the real-time reconstruction algorithm,and then establishing the human body model based on the basic model by combining the weight parameters and the human body parameters. The invention provides the human body modeling method based on a depth sensor, which has high use and popularization values.

Description

technical field [0001] The invention relates to a modeling method, in particular to a method for establishing a human body model based on a depth sensor, and belongs to the field of human-computer interaction. Background technique [0002] With the continuous advancement of computer technology and sensor performance, Human-Computer Interaction (Human-Computer Interaction) technology has developed to the human-centered Natural User Interface (Natural User Interface) interaction stage, which requires machines to interact with users as naturally as humans interact. [0003] The tailor-made and personalized production of electronic clothing has become the development trend of the clothing industry, and the emergence of non-contact 3D human body measurement system has made this trend possible. At present, domestic non-contact 3D anthropometric technology is relatively backward. However, foreign non-contact three-dimensional anthropometric equipment is relatively large in size a...
