Interactive 3D scanning system for measuring human body height based on ultrasonic and scanning method of interactive 3D scanning system

Abstract

The invention discloses an interactive 3D scanning system for measuring human body height based on ultrasonic and a scanning method of the interactive 3D scanning system. The interactive 3D scanning system includes a server, a handheld terminal, a PC, an MCU chip, a weighing sensor, an ultrasonic distance measuring module, a turntable module and a camera module; the handheld terminal is connected with the PC and transmits scanning instructions to the PC; the MCU chip is connected with the PC; and the weighing sensor, the ultrasonic distance measuring module, the turntable module and the camera module are respectively connected with the MCU chip. The 3D scanning method includes the following steps that: the handheld terminal transmits scanning instructions to the PC; the PC transmits human body data acquisition instructions to the MCU chip; the MCU chip transmits data to the PC; the PC transmits the scanning instructions to the MCU chip; the MCU chip controls the camera and the turntable to move cooperatively so as to perform scanning, and transmits scanning information to the PC; the PC generates a three-dimensional model; and the handheld terminal accesses the three-dimensional model stored on the server of the PC. The interactive 3D scanning system and the scanning method have the advantages of high function integration, high equipment control accuracy and low error rate.

Description

technical field [0001] The invention relates to the field of 3D scanning, in particular to an interactive 3D scanning system and a scanning method for measuring human body height based on ultrasonic waves. Background technique [0002] 3D scanning technology is an emerging technology. It is a basic process technology. After obtaining three-dimensional data through 3D scanning, it can provide technical support for animation, games, 3D printing, etc., and quickly and accurately obtain three-dimensional data of objects through 3D scanning. Generate 3D models, which can be used in animation, game and other models, which greatly reduces the difficulty of animation and game production. At the same time, as the front-end technology of 3D printing, the 3D data of the object can be obtained through 3D scanning, and the 3D data can be sent to the 3D printer for printing out the corresponding object. [0003] Human body 3D scanning technology uses 3D scanning exclusively for human bod...

Problems solved by technology

[0004] The Chinese utility model patent "A Smart 3D Scanner" with the authorized announcement number CN 204244331 U also discloses a scanner with a rotating structure. The difference from the previous two patent technologies is that the movement direction of the scanning device The vertical direction is replaced by the horizontal direction, and the device is not dedicated to human body scanning, but mainly used for scanning other objects. The core technology adopted is to emit light through the light generator to irradiate the object to be scanned, and the smart terminal camera receives the image of the object after the light is irradiated. , and then calculate and process the light points on the image to obtain point cloud information on the surface of the object. After the point cloud information is processed, the 3D model data of the object is obtained; The scanning process of processing needs to be equipped with a special light emitter, which has very high requirements on the external light environment during scanning, and is easily affected by the external environment, and its scanning accuracy is low; The equipment requirements are high, so its practicability is poor, and it does not have practical promotion value
