Three-dimensional reduction photographing longitudinal and transverse rotating mechanism for T-shaped photographing frame

Abstract

The invention discloses an appliance for three-dimensional reduction reconstruction, in particular to a three-dimensional reduction photographing longitudinal and transverse rotating mechanism for a T-shaped photographing frame. A square mounting frame (14) is fixedly connected to the end of a sliding shaft (4) through a longitudinal rotating mechanism (19) and a transverse rotating mechanism (13); a square section transverse rod (15) capable of converting one, two or three of 90 degrees is inserted into the square mounting frame; a short shaft (19a) erects at the upper end of a long base rod (17); a flat shaft (13f) is arranged at the lower end of the long base rod (17); a rotating rod (19h) is arranged on the short shaft (19a); the rotating rod (19h) is provided with a clamping clip (19g) with a polygonal hole; and arc toothed plates are respectively fixed on the base rod (17) and the flat shaft (13f) and are driven by a numerical control motor through a worm gear and worm and a reducing gear. The three-dimensional reduction photographing longitudinal and transverse rotating mechanism is simple and compact in structure, the 360-degree all-around adaptive regulation effect can be realized through the 90-degree longitudinal rotating mechanism only, the mechanism is a unique and ingenious technical scheme in the field and has high economical efficiency, practicality and creativity.

Description

technical field [0001] The invention relates to an apparatus used for three-dimensional restoration and reconstruction, and in particular relates to an adjustment structure of a shooting frame for installing an image acquisition device and an optical interference source for three-dimensional restoration shooting. Background technique [0002] 3D reconstruction technology is currently one of the most attractive topics in the world. Countries around the world have invested heavily in pursuing and improving more realistic reconstruction effects, higher reconstruction accuracy, and faster reconstruction speed. [0003] The so-called holographic three-dimensional reconstruction technology is based on the principles of computer stereo vision, computer graphics and optical imaging, to obtain images of three-dimensional space objects, digital measurement and restoration and reconstruction methods and devices. [0004] The conventional method is to use at least two image sensors with...

Problems solved by technology

In order to completely restore the painted sculpture, digital cameras and optical interference sources need to be extended into the underarms, behind the arms, and the back side of the painted sculpture in many occasions to take pictures. , and it can realize long-distance electric control or remote control, etc.

The special requirements for the installation, configuration and adjustment of digital cameras and optical interference sources are not provided by the existing technology and cannot be realized. In order to better realize the three-dimensional reconstruction of special objects, it is urgent to provide an all-round, flexible and mobile image acquisition instrument A shooting frame structure with light interference source

[0008] In a narrow space, the image acquisition instrument and the optical interference source fixed on the shooting frame can be rotated in all directions up and down, left and right. The existing technology is almost blank, or the mechanism is huge, or the structure is complicated, or the use is not flexible and inconvenient. Automatic control, there is an urgent need for improvement measures
