Problems solved by technology

[0003] One is that the rotation track provided for the camera is limited; the other is that it is impossible to guarantee that the actual geodetic coordinates of the camera will remain unchanged during the rotation movement, and its direct impact will bring difficulties to office processing, that is, photo matching and synthesis, which is unavoidable affect the accuracy of the final 3D digital model

Abstract

The invention discloses a rotary support for a three-dimensional digital geologic photogrammetry system. The rotary support comprises a tripod (1), a horizontal rotary bent rod (9) and a vertical rotary slide groove (7), wherein a support fixing base (3) is installed on the tripod (1), and connected with the horizontal rotary bent rod (9); the horizontal rotary bent rod (9) is connected with the vertical rotary slide groove (7); and a vertical slide block (11) is arranged in the vertical rotary slide groove (7), and a camera fixing base (6) is installed on the vertical slide block (11). The rotary support disclosed by the invention is capable of conveniently adjusting the rotation angles of a camera in the horizontal direction and the vertical direction, thereby expanding the camera-shooting sampling range; and meanwhile, different pictures can be integrated into a large regional three-dimensional picture through reference points on the pictures.

Description

technical field [0001] The invention relates to a camera rotating support, in particular to a rotating support of a geological three-dimensional digital photogrammetry system. Background technique [0002] The application of digital photogrammetry technology in the field of geological engineering in the field of engineering is mainly to establish a digital model of the surface of geological bodies through photographic technology to provide data and analysis basis for the sketching, cataloging, and safety monitoring of geological features. The basic principle of this technology is to use the two-dimensional digital photos obtained on-site and the coordinate information of the on-site measurement points, and introduce the computer application technology of graphics and perspective theory to carry out three-dimensional synthesis. The coordinates of the measurement points are provided by the surveying and mapping profession. According to the design work plan, the designated geol...
