3D Body Size Measurement Based On Depth Camera

Non-contact 3D body measurement device from foreign market is so large and expensive that many apparel industries can not afford it.As Kinect somatosensory game peripherals,once they come attracted wide attention.In view of the important features of Kinect can get a three-dimensional data of the object,you can use Kinect to obtain three-dimensional data of the human body were reconstructed,and then parts of the human body characteristics were measured,the measurement data can be used as a parameter back to the custom clothing custom clothing business.At the same time it is a small volume,high precision and low cost 3D scanner.For that reasons,a scheme of 3D body measurement system based on the depth camera has been proposed.The main contributions of this thesis can be summarized as follows:(1)Depth image fusion for parts of 3D body.First depth camera is calibrated and rotation matrix and translation vector are obtained,then 3D human image are real-time fused using the rotation matrix and translation vector,finally,3D human point cloud data is obtained by point cloud data of passing SQL database.(2)3D body segmentation.The 3D point cloud data of each parts of 3D body are stored in chain table.The feature from the each part of 3D body is found out and the feature points are found out,then the body is segmented according to x and y of the feature point.(3)3D body measurement based on convex hull method.First the body feature points are found out using scale range of the body,then the location of the body feature points is measured and the circumference and length are measured.We believe this project will develop a system of customized clothing enterprises to bring more convenience.
