A high-precision orthophoto image PTZ

Abstract

The invention discloses a high-precision orthophoto cloud platform, which includes a cross pendulum mechanism, a mounting frame, an RTK / PPK antenna mounting seat, a camera mounting seat, a servo motor, an IMU flight control and an aluminum alloy pipe clamp, and an end of the cross pendulum mechanism. The end of the vertical axis of the cross pendulum mechanism is equipped with an RTK / PPK antenna mounting seat, the other end of the vertical axis of the cross pendulum mechanism is installed with a camera mounting seat, and one side of the mounting frame is equipped with a servo motor , the other side of the installation frame is equipped with IMU flight control; the servo motor is the steering gear. The present invention can not only improve the balance of the camera, reduce vibration and shaking, but also maintain a straight-line relationship between the mounted RTK / PPK and the camera, which can ensure orthographic images, achieve better image overlapping effects, and have a good shooting angle verticality , Office data processing is easier; not only has high-precision servo tracking capabilities, but also allows RTK / PPK and cameras to maintain a fixed positional relationship without being affected by the flight attitude of the drone.

Description

technical field [0001] The invention relates to an image cloud platform, in particular to a high-precision orthophoto image platform. Background technique [0002] During the aerial survey of the rotor UAV, due to the needs of flight operations, the UAV will produce changes in flight attitude such as tilt and pitch. The deviation between the spatial coordinates obtained by PPK and the position of the principal point of the photo taken by the camera cannot even be matched, which is not conducive to the processing of post-office data and cannot meet the application requirements of high-precision aerial surveying. For the UAV platform, the high-performance gimbal is the key component to improve the performance of the UAV-related load, and it is an important link that affects the completion of high-precision aerial surveys. Therefore, a high-precision orthophoto gimbal is currently needed. It allows RTK / PPK and the camera to maintain a fixed positional relationship without bein...
