Description

Technical Field

[0001] This utility model relates to the field of aerial photography technology, specifically to an intelligent aerial photogrammetry device. Background Technology

[0002] An aerial camera is an optical instrument mounted on an aircraft to capture images of ground targets from the air. The basic components of an aerial camera are the camera body and the controller. The camera body generally consists of a film cassette, darkroom, and objective lens, primarily used to form optical images and obtain latent images from the film. The controller is used for remote control and monitoring of the camera's operation. A cable connects the camera and the controller. An aerial camera typically contains an optical system, a recorder, and various working mechanisms. Aerial cameras produce high-resolution images of ground targets, facilitating the identification of small targets, and are therefore widely used. Their main technical performance parameters are focal length, angle of view, resolution, film count, duty cycle, and exposure time range. Different structural features and main performance parameters lead to different applications. Low-altitude, high-speed reconnaissance photography often uses short-focal-length aerial cameras with short duty cycles, short exposure times, and image shift compensation devices. High-altitude reconnaissance photography often uses long-focal-length aerial cameras with a large film count and image shift compensation devices. Surveying and mapping photography commonly uses wide-angle aerial cameras with low distortion and short focal lengths. Several different types of aerial cameras can be installed on an aircraft to conduct aerial photography under various conditions. The development trend of modern aerial cameras is towards a wide focal length range, a large number of films, a wide field of view, high resolution, high image quality, and high automation.

[0003] Authorization announcement number CN218822365U discloses an intelligent aerial photogrammetry device. This patented technology employs a protective cover with an upper and lower partition structure. On the one hand, this protects the camera from external dust and rain damage. On the other hand, it allows for the addition of a ring guide rail and mounting plate on the lower partition. A hemispherical observation window is set on the mounting plate, enabling multiple cameras to share a single hemispherical observation window. When switching between different lenses, the controller can precisely control the rotation of the hemispherical observation window to the area below the desired camera, and then control the corresponding guide rod cylinder to push the camera into the hemispherical observation window. This is convenient, quick, and highly sensitive. A heat sink dissipates the heat generated inside the protective cover, ensuring all instruments are at a suitable operating temperature, thereby extending the instrument's lifespan. However, in aerial photogrammetry, this method of protecting the camera with a protective cover significantly affects the detection range, resulting in blind spots in the detection area. Furthermore, the device lacks flexibility and is not suitable for long-term operation. Therefore, an intelligent aerial photogrammetry device is needed to address these issues. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example: Please refer to Figures 1-4 The intelligent aerial photogrammetry device shown includes a disassembly and assembly component 1, a range adjustment component 2 is provided on the top of the disassembly and assembly component 1, and a flip protection component 3 is provided on the bottom of the range adjustment component 2.

[0027] In this embodiment, reference is made to Figure 1 , Figure 2 and Figure 4 As shown, the disassembly and assembly assembly 1 includes a base plate 101; the range adjustment assembly 2 includes a mounting bracket 201, with a top box 203 fixedly connected to the top of the mounting bracket 201; a first motor 204 is installed inside the top box 203; a rotating wheel 205 is fixedly connected to the output end of the first motor 204; a transmission wheel 206 is meshed with the side of the rotating wheel 205; and a rotating rod 207 is fixedly connected to the bottom of the transmission wheel 206; the flip protection assembly 3 includes a connecting plate 301, with a protective frame 302 fixedly connected to the bottom of the connecting plate 301; a camera 303 is installed inside the protective frame 302; a support plate 304 is fixedly connected to the bottom of the base plate 101; and side plates 307 are fixedly connected to the sides of the support plate 304. A protective box 308 is fixedly connected to the side of the side plate 307. A second motor 309 is installed inside the protective box 308. A connecting rod 306 is fixedly connected to the output end of the second motor 309. The connecting rod 306 extends into the protective frame 302 and is fixedly connected to the camera 303. The first motor 204 drives the rotating wheel 205 and the transmission wheel 206 to mesh and rotate, which in turn drives the rotating rod 207 to rotate inside the first bearing seat 208 and the second bearing seat 209. This allows the disassembly assembly 1 and the flip protective assembly 3 at the bottom of the rotating rod 207 to be rotated and adjusted, thereby expanding the detection range of the camera 303 and increasing the flexibility when performing aerial photogrammetry.

[0028] The top box 203 has a first bearing seat 208 fixedly connected inside, and a rotating rod 207 extends into the first bearing seat 208. The mounting bracket 201 has a protective tube seat 202 fixedly connected inside, and a second bearing seat 209 is fixedly connected inside the protective tube seat 202. The rotating rod 207 extends into the second bearing seat 209. The bottom of the support plate 304 has a third bearing seat 305 fixedly connected to, and a connecting rod 306 extends into the third bearing seat 305. The second motor 309 drives the connecting rod 306 to rotate inside the third bearing seat 305, which can flip the camera 303. This allows the detection end of the camera 303 to be perpendicular to the ground, increasing the detection range. The flipping also allows the detection end of the camera 303 to face upwards, protecting the camera 303 with the connecting plate 301 and the protective bracket 302, thus increasing the service life of the camera 303.

[0029] In this embodiment, reference is made to Figure 1 and Figure 3 As shown, a threaded rod 102 is fixedly connected to the top of the base plate 101. A loading plate 105 is provided on the top of the threaded rod 102. There are four threaded rods 102. A nut 103 and a washer 104 are provided on the top of the loading plate 105. The threaded rod 102 is threadedly connected to the nut 103. There are four nuts 103 and washer 104. A positioning tube seat 106 is fixedly connected inside the loading plate 105. The positioning tube seat 106 extends to the top of the base plate 101. The combination of the threaded rod 102 and the nut 103 facilitates the disassembly of the range adjustment assembly 2 and the overturning protection assembly 3. The washer 104 has the functions of filling gaps, compensating for unevenness, distributing pressure, and improving sealing.

[0030] In this solution, an intelligent aerial photogrammetry device utilizes a threaded rod 102 on the top of the base plate 101 to connect with a nut 103 on the top of the loading plate 105, allowing the range adjustment component 2 and the flip protection component 3 to be assembled. During detection, the first motor 204 drives the rotating wheel 205 and the transmission wheel 206 to mesh and rotate, thereby causing the rotating rod 207 to rotate inside the first bearing seat 208 and the second bearing seat 209. This allows for the rotation and adjustment of the disassembly and assembly component 1 and the flip protection component 3 at the bottom of the rotating rod 207, enabling the detection of the surrounding environment. The second motor 309 drives the connecting rod 306 to rotate inside the third bearing seat 305, flipping the camera 303 so that the detection end of the camera 303 is perpendicular to the ground. While detecting the bottom of the aerial photograph, the camera 303 can also be flipped so that the detection end faces upwards, protecting the camera 303 with the connecting plate 301 and the protective frame 302.
