Embodiment Construction

[0013] In order to facilitate the understanding of the present invention, an embodiment is given to further illustrate the present invention.

[0014] Taking the three-dimensional coordinates as (90, 120, 65), and the RGB length and width pixel values ​​as 320 and 240 respectively as an example,

[0015] In step one, the three-dimensional space coordinates 90, 120, and 65 formed between the human body and the human body are acquired through the Kinect device and stored respectively.

[0016] Step 2, obtain the real-time RGB image data of the human body through the Kinect device, and save the data.

[0017] Step 3: Calculate the length and width values ​​of RGB, set the length as A data, and design the width as B data and save them separately.

[0018] Step 4, calculate the acquired data values, RGB_X=0-(320 / 2-90), RGB_Y=0+(240 / 2-120), and obtain the two-dimensional coordinate (-70, 0).

Abstract

The invention aims to provide a method for converting a three-dimensional coordinate to a two-dimensional coordinate of a human body in Kinect device based three-dimensional stereo fitting application. In order to realize the purpose, the technical scheme adopted by the invention comprises: a first step of obtaining data information Joint of a three-dimensional spatial coordinate formed between a human body and the Kinect device through the Kinect device and storing the data for spare use; and a second step of extracting three-dimensional coordinate values of three-dimensional coordinate points needing treatment in the Joint and providing the data for SkeletonToDepthImage function calculation through the KinectSDK to obtain an X-axis coordinate value depthX and a Y-axis coordinate value depthY of the point in a depth graph.

Description

technical field [0001] The invention relates to the application field of human body recognition, in particular to a method for converting human body three-dimensional coordinates into two-dimensional coordinates in the three-dimensional fitting application based on a Kinect device. Background technique [0002] Based on the shortcomings of traditional fittings, people have developed a three-dimensional fitting method based on the combination of human body images and virtual product maps to replace physical fittings, so that shoppers can wear their favorite clothes on models. Specifically, It is a combination of clothing pictures and model images, which is convenient and intuitive to see the matching effect of the clothes, shoes and hats selected by the user, until the user's own satisfactory style is matched before buying. [0003] In the existing three-dimensional fitting devices, most of them first use Kinect equipment as their human body recognition device, so as to obtai...
