Human body 3D scanning rotation speed self-adaptive control system and control method thereof

Abstract

The invention discloses a human body 3D scanning rotation speed self-adaptive control system and a control method thereof. The human body 3D scanning rotation speed self-adaptive control system comprises an MCU chip, a turntable motor driving module, a Hall speed measuring sensor, a power supply module and a turntable motor, wherein the MCU chip is connected with the turntable motor driving module; the Hall speed measuring sensor and the turntable motor are each connected with the turntable motor driving module; and the Hall speed measuring sensor is connected with the MCU chip to form a closed-loop control system. The control method comprises the steps that: the MCU chip presets a turntable rotation speed preset value; the MCU chip sends a command to the turntable motor driving module; the turntable motor rotates at a constant speed of the preset value; a human body stands on a rotating turntable; the Hall speed measuring sensor senses variation of rotation speed of the turntable; the MCU chip calculates a deviation value according to a feedback signal to form a turntable motor power changing amount; and the turntable motor driving module controls power of the turntable motor. The human body 3D scanning rotation speed self-adaptive control system and the control method thereof shorten the corresponding time between the rotation speed change value to the preset value, and avoid the turntable from affecting scanning quality due to rotation speed variation.

[0002] Human body 3D scanning system, also known as three-dimensional anthropometric system, human body digitization system, is widely used in clothing, animation, ergonomics, and medicine. It is the development of human body (face) pattern recognition, special clothing design (such as aerospace suits, Diving suits), special equipment for the human body (human prosthetics, personalized weapons and equipment), and ideal tools for ergonomics research; human body 3D scanning technology uses 3D scanning exclusively for human body scanning in order to establish a complete and detailed three-dimensional model of the human body, 3D scanning technology needs to scan the human body at 360° in all directions. The 3D human body scanner adopts a structure that combines the vertical movement of the camera and the uniform rotation of the rotating turntable. Carry out all-round and vertically moving cameras to scan different heights of the human body; in the actual scanning process, when the rotating turntable rotates at a constant speed, multiple scanners scan one by one, and the scanners replace stations on the rotating turntable. The weight of each scanner is different, and the pressure on the rotating turntable also changes gradually. The pressure change directly affects the rotating speed of the rotating turntable, and the moving speed of the scanner camera and the rotating speed of the rotating turntable have been set in advance. Changes in the rotating turntable speed will inevitably lead to The scanned model is incomplete, and when the speed changes too much, it may even appear distorted and deformed, which will affect the scanning quality. At the same time, when the human body stands on the rotating turntable, the standing will be unstable due to the change of speed; therefore, it is necessary to design a speed control system , to control and adjust the speed in real time to ensure the scanning effect
