Description

Technical Field

[0001] This utility model belongs to the field of drone aerial photography technology, and more specifically, it relates to an auxiliary device for stitching drone aerial images for land spatial planning. Background Technology

[0002] Territorial spatial planning is a strategic, fundamental, and binding plan formulated by a country or region to scientifically plan and rationally utilize land and marine space within a certain area in order to achieve sustainable development. In the specific implementation process, drone aerial photography has become an important means of obtaining high-precision geographic information. After completing aerial photography of a certain area, it is usually necessary to stitch the acquired images together to form a complete regional image map, which provides data support for subsequent spatial analysis and planning decisions.

[0003] According to application number CN201820330454.9, a camera module mounting structure for rapid stitching of UAV video stream images includes a body and a connecting device. The connecting device includes a mounting plate, a support plate, a rotating shaft, a drive motor, a telescopic tube, a fixing block, a camera, and a connecting cap. The middle of the mounting plate is fixedly connected to the bottom of the body by screws. Support plates are symmetrically fixed to the bottom of the mounting plate and are arranged in parallel. One end of the rotating shaft is rotatably connected to the support plate on one side of the bottom of the mounting plate through a bearing. The other end of the rotating shaft passes through the support plate on the other side of the bottom of the mounting plate and is fixedly connected to the output shaft of the drive motor. The drive motor is also fixedly connected to the support plate. The top of the telescopic tube is fixedly connected to the rotating shaft, and a fixing block is installed at the bottom of the telescopic tube. This camera module mounting structure for rapid stitching of UAV video stream images allows the camera height to be changed by a push rod motor, thereby further increasing the adjustment range.

[0004] Based on the above, existing drone aerial image stitching auxiliary devices typically use multiple bolts to fix them to the bottom of the drone. During installation and disassembly, the bolts need to be tightened and loosened repeatedly, which is cumbersome, time-consuming, and affects work efficiency. Utility Model Content

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention facilitates the installation of mounting components through its mounting mechanism. After the mounting components are placed against the lower end face of the drone body, rotating the operating knob causes the threaded rod to rotate synchronously. The threaded rod slides under the action of its threaded engagement with the fixed rod. Simultaneously, the sliding connection structure between the square groove and the square rod ensures that multiple threaded rods can move synchronously. The cooperation between the positioning groove and the positioning ball provides limit fixation for the operating knob, simplifying operation and effectively improving work efficiency. The auxiliary adjustment mechanism enables the adjustment of the camera angle. When the adjustment motor is activated, it drives the camera to adjust its pitch forward and backward through the mounting block. When the rotary motor is activated, it drives the camera to rotate horizontally, thus meeting the shooting needs of different angles and further improving the efficiency and quality of image stitching. Through the above-mentioned mechanism, not only is the assembly and disassembly of the mounting components facilitated and the work efficiency improved, but the multi-angle adjustment function of the camera is also realized, enhancing the effect and practicality of aerial image stitching.
