Description

Technical Field

[0001] The utility model relates to the technical field of aerial surveying and mapping, and particularly relates to a stable pod for aerial surveying and mapping. Background Art

[0002] With the increasing maturity of UAV technology, its application in the field of surveying and mapping is becoming more and more extensive. UAV aerial surveying and mapping has the advantages of high accuracy, high efficiency, and the ability to analyze data. UAV aerial surveying and mapping is mainly completed by a surveying and mapping camera installed in a pod under the aircraft. UAVs can take pictures in cloudy weather, fly at low altitudes, and can obtain high-resolution and high-clarity image information. At the same time, UAVs fly slowly, with a speed of dozens of kilometers per hour, and can flexibly cope with complex terrain conditions to obtain accurate images. Most of the surveying and mapping pods of ordinary UAVs have the phenomenon of unstable surveying and mapping cameras. In aerial surveying projects, there are defects such as jitter in the captured images, which bring many adverse factors to aerial surveying and mapping, resulting in the problem that the vibration of the lens during shooting makes the image unstable and affects the shooting quality.

[0015] Referring to Figures 1 to 3 , the utility model provides a stable pod for aerial mapping, which comprises a concave rotating frame 2 and an azimuth hanging frame 3. A mapping camera 1 is arranged in the middle of the lower end of the rotating frame 2. The rotating frame 2 is connected to the azimuth hanging frame 3 through a fixed adjusting knob 6, and the fixed adjusting knob can rotate along its axis to adjust the rotating frame and the mapping camera. An azimuth turntable 4 is arranged in the middle of the upper end of the azimuth hanging frame 3, and the azimuth turntable can rotate along its axis to the azimuth hanging frame and the mapping camera. An installation plate 5 is arranged at the top end of the azimuth turntable 4, and the pod is installed at the bottom of the unmanned aerial vehicle through the installation plate. A stabilizing member 7 for stabilizing the bottom of the mapping camera 1 is connected to the rotating frame 2.

[0016] Referring to Figure 1 , Figure 3 , the stabilizing member 7 is composed of a clamping strip 7.1 symmetrically arranged on the left and right connected by a supporting ring 7.2 in the middle. The supporting ring 7.2 attached to the bottom of the mapping camera 1 is sleeved on the lens of the mapping camera 1, and the clamping strip 7.1 is clamped to the rotating frame 2. The clamping strip is clamped and arranged, which is convenient for loading and unloading, the supporting ring stably supports the mapping camera at the lower side, and the rotating frame and the supporting ring stably map the camera at the upper and lower sides.

[0017] The lower end face of the lens protection cylinder is lower than the lower end face of the surveying and mapping camera lens to prevent collision with the lens of the surveying and mapping camera. A lens protection cylinder 7.3 is coaxially arranged at the lower end of the support ring 7.2.

[0018] The thicknesses of the clamping strip 7.2, the rotating frame 2, and the azimuth hanging frame 3 increase in sequence. The load-bearing capacities of the azimuth hanging frame, the rotating frame, and the stabilizing member decrease in sequence, and the structural strength and load-bearing capacity are increased according to requirements.
