High-precision full-frame oblique photogrammetry device for unmanned aerial vehicle

Abstract

The invention discloses a high-precision full-frame oblique photogrammetry device for an unmanned aerail vehicle, which comprises an unmanned aerial vehicle connecting and assembling base, a second rotating angle adjusting structure and a second angle rotating sensor, and assembling and fixing bolts are arranged at the four corners of the unmanned aerial vehicle connecting and assembling base. A first rotating angle adjusting structure is arranged on the upper end face of the unmanned aerial vehicle connecting and assembling base, the second rotating angle adjusting structure is arranged abovethe first rotating angle adjusting structure, and a first angle rotating sensor is arranged on the upper right portion of the second rotating angle adjusting structure. According to the full-frame oblique photogrammetry device, multi-angle adjustment can be conveniently carried out on image shooting through the arranged first rotating angle adjusting structure, so that 360-degree dead-angle-freeshooting can be conveniently carried out by the photogrammetry device in the horizontal plane, and the rotating shooting angle of the photogrammetry device can be conveniently measured through the arranged first angle rotating sensor; therefore, the rotating shooting angle in the horizontal plane can be conveniently known.

Description

technical field [0001] The invention relates to the technical field of UAV photography, in particular to a UAV high-precision full-frame oblique photogrammetry device. Background technique [0002] Oblique aerial photography is relative to vertical aerial photography. The purpose of traditional aerial photography to obtain orthophotos is to use a photographic method with an inclination angle of less than 2-3°, which is called vertical aerial photography. This method is convenient for subsequent processing such as orthorectification and stereo mapping, but it will lose the side elevation details of the ground object. [0003] General aerial photography cannot achieve the problem of image and texture acquisition of the top and side elevations of ground objects when shooting. Therefore, we propose a more practical UAV high-precision full-frame tilt photogrammetry device. Contents of the invention [0004] The purpose of the present invention is to provide a high-precision fu...
