Human body back three-dimensional reconstruction device for human body scoliosis detection

Abstract

The invention discloses a human body back three-dimensional reconstruction device for human body scoliosis detection. The device comprises a display screen, the bottom of the display screen is fixedlyconnected with a base; one side of the display screen is fixedly connected with a computer host; one side of the computer host is fixedly connected with a TOF depth camera; The top of the TOF depth camera is connected with a high-speed motor, the top of the high-speed motor is connected with a fixing ring, the outer surface of the high-speed motor is connected with a limiting ring, one side of the high-speed motor is movably connected with a light shielding piece, and a second wire is connected between the TOF depth camera and a motor driving controller. A control shading sheet and the like are designed and mounted; A plurality of TOF depth cameras can be started at the same time under the condition that the TOF depth cameras do not interfere with one another, so that the data acquisitionspeed is increased, the precision is improved through data acquired by the depth cameras at different positions, and data of a high-precision human body back three-dimensional model for human body scoliosis detection can be acquired within 1 second.

Description

technical field [0001] The invention belongs to the field of electronic technology, and in particular relates to a human body back three-dimensional reconstruction device used for detecting human body scoliosis. Background technique [0002] The TOF depth camera consists of an infrared emission module, an infrared camera, and an RGB camera. The infrared transmitter module emits infrared light waves to the object, and the infrared camera receives the infrared light emitted by the object to calculate the depth data, while the RGB camera is used to collect the image data of the material set. [0003] Existing 3D reconstruction devices generally use the 3D reconstruction technology of a single TOF depth camera, so the reconstruction must take a long time, about ten seconds to several minutes, and it is difficult to realize the demand scene of reconstructing the three-dimensional back of the human body, because the human body It is non-rigid and difficult to keep still for a lon...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a human body back three-dimensional reconstruction device for human scoliosis detection, to solve the above-mentioned background technology. It takes a long time, about ten seconds to several minutes. It is difficult to realize the three-dimensional reconstruction of the human back, because the human body is non-rigid and it is difficult to keep still for a long time. If the scanning time is shortened or directly maintained If the depth camera does not move, its noise will increase significantly. For active binocular devices, the noise is so large that it is difficult to restore an accurate 3D model of the human back
