Description

Technical Field

[0001] The utility model belongs to the field of measurement technology, in particular to a three-dimensional real scene measurement device based on an oblique photography model. Background Art

[0002] Oblique photography technology is a high-tech technology developed in the international surveying and mapping field in recent years. It overturns the previous limitation that orthophotos can only be taken from a vertical angle. By carrying multiple sensors on the same flying platform, it simultaneously collects images from five different angles, including one vertical, four oblique angles, etc., introducing users into a real and intuitive world that conforms to human vision.

[0003] In order to improve the photographic range of the three-dimensional real scene measurement equipment based on the oblique photography model, it is necessary to adjust the angle of the oblique camera. However, in the prior art, most of the oblique cameras on the three-dimensional real scene measurement equipment based on the oblique photography model realize angle adjustment through two motors, and the distribution of the two motors is usually to fix one of the motors on the other motor through a connecting structure, which will result in that one motor always bears a greater load than the other motor, thereby affecting the service life of the motor, and further affecting the use effect of the three-dimensional real scene measurement equipment based on the oblique photography model. For example, a three-dimensional real scene measurement equipment based on the oblique photography model provided by the Chinese utility model patent with announcement number CN217236800U includes a drone, wherein the upper left part and the upper right part of the drone are jointly equipped with an extraction device, the upper left part and the upper right part of the drone are both equipped with two arms, the upper ends of the four arms are all equipped with rotors, the middle part of the lower end of the drone is equipped with a vertical camera, the lower left part and the lower right part of the drone are both equipped with two adjustment camera devices, and the lower left part and the lower right part of the drone are both equipped with a buffer support device. The utility model discloses a three-dimensional real scene measuring device based on an oblique photography model. By adjusting the camera device, the oblique camera can be adjusted according to the acquisition needs, which not only improves the practicability of the device, but also improves the measurement effect of the device through multi-faceted acquisition. The buffer support device reduces the shaking of the drone and improves its stability.

[0004] Although the above device can adjust the angle of the tilt camera, the above device achieves angle adjustment through two motors, and the distribution of the two motors is usually to fix one of the motors to the other motor through a connecting structure. This will result in one motor always bearing a greater load than the other motor, thereby affecting the service life of the motor, and further affecting the use effect of the three-dimensional real-scene measurement device based on the tilt photography model.
