Description

Technical Field

[0001] The utility model relates to the technical field of photogrammetry, in particular to an oblique photogrammetry device. Background Technique

[0002] Oblique photography technology is a high-tech developed in the international photogrammetry field in the past ten years. This technology synchronously collects images from one vertical, four oblique, and five different perspectives, introducing users into a real and intuitive world that conforms to human eye vision. Through the application of supporting software, measurements including height, length, area, angle, slope, etc. can be directly carried out based on the resulting images, expanding the application of oblique photography technology in the industry.

[0003] In the Chinese utility model patent application number: CN202222331415.X, a digital aerial oblique photogrammetry device is disclosed. By setting air inlets and heat dissipation holes on the chassis and a radiator in the heat dissipation holes, the high temperature generated inside the chassis can be effectively cooled. Moreover, the high temperature generated by the camera is conducted into the chassis through the metal steering ball and the metal connecting rod, and the air flowing inside the chassis is used to cool it, which can extend the working time of the camera. By setting a motor in the central column, the motor drives the bevel gear disk to drive the turntable to rotate, so that the two side oblique cameras rotate. Rotating shooting can effectively prevent blind spots from appearing in the bottom shooting area; by setting a connecting rod on the turntable, the connecting rod is supported by a telescopic rod and a spring, and the hydraulic cylinder is used to drive the movable plate to act on the connecting rod, so that the inclination angle of the connecting rod changes, and then the inclination angle of the oblique camera changes, so as to achieve the purpose of changing the shooting angle of the oblique camera. At the same time, the overall structure of the utility model has high stability and low cost.

[0004] Although the above patent realizes the function of adjusting the inclination angle of the oblique camera, however, the above patent has the following disadvantages when in use: The above digital aerial oblique photogrammetry device is usually fixedly installed at the bottom of the unmanned aerial vehicle as a whole through multiple groups of bolts, and auxiliary tools are required for both installation and disassembly, which causes difficulties in installation and maintenance, low work efficiency, and inconvenient operation. Therefore, we propose an oblique photogrammetry device. Content of the Utility Model
