Multi-camera device for human body 3D scanning

Abstract

The invention discloses a multi-camera device for human body 3D scanning. The multi-camera device comprises more than one camera units, more than one steering engines, a signal processing board, a router, a switch power, and wire rod; the multi-camera is connected with the computer through a cable; the multi-camera is used for acquiring a human body image and transmitting the same to the computer to perform the image processing. The invention aims at providing data acquisition equipment with simple structure, low cost, convenient operation, high scanning efficiency, accurate scanning result, and small floor area for the problem existent in the existing human body 3D modeling scanning equipment; the data acquisition equipment is mainly used for 3D photo studio (3D printed portrait, crystal inter-carven), films and games, augmented reality, virtual fitting, medical assistance, reforming prediction, human body form parameter measurement and like fields.

Description

technical field [0001] The invention relates to the technical field of three-dimensional close-range photogrammetry, in particular to a multi-eye camera device for three-dimensional scanning of a human body. Background technique [0002] The mainstream technology of 3D human body scanning can be divided into two types: passive scanning and active scanning. Among them, active 3D scanning technologies include laser scanning, structured light scanning, time-of-flight (TOF, time-of-flight), etc. Existing 3D human body scanning systems, such as Cyberware based on the principle of laser scanning in the United States, have high precision. But the price is expensive (more than 200,000 US dollars); Mega3PofInSpeck based on white light stripe scanning, Shenzhen Yishang 3D body scanning system, etc., scan the human body from multiple perspectives, the scanning time is fast, and the whole body scan can be completed within 5 seconds. However, the degree of color reproduction is average,...

AI Technical Summary

Problems solved by technology

For example, the Visbody of Xi’an Suanni Technology has a beautiful appearance, short acquisition time, and good modeling effect, but the accuracy is insufficient and the price is expensive; another example is an instantaneous 3D camera system based on a camera array, the publication (announcement) number CN203708345U, this patent As mentioned above, this solution has complex equipment structure, high investment cost, large space occupation, high requirements for light, and many auxiliary equipment, so it is difficult to modularize, automate, and scale production and promotion. The stability of the entire set of equipment is poor, and problems can be eliminated. difficulty

In general, the market demand for human body scanning is huge and will increase year by year, but the above-mentioned human body scanning costs are high, which is not conducive to wide-scale promotion and use

[0004] Existing technology: Scanning people or objects with a single camera—requires multiple shots in multiple spatial locations, unable to capture dynamic object shapes instantly; scanning people or objects with an array of cameras—complex structure, numerous connecting lines, high cost, and difficult operation. The system is unstable, takes up a lot of space, and cannot be mass-produced
