Technical Field

[0001] This utility model relates to the field of remote sensing unmanned aerial vehicle (UAV) technology, and in particular to a device for extracting and analyzing photogrammetric remote sensing feature data from multi-source satellite imagery. Background Technology

[0002] Remote sensing drones are a technological system that uses drones equipped with remote sensing sensors to conduct surface observation and data collection. They consist of a flight platform, remote sensing payload, data transmission and processing system, and ground control station. They can autonomously complete data collection, transmission, and analysis, and have been widely used in fields such as disaster emergency response, agricultural monitoring, and land resources and urban planning.

[0003] To address this, patent CN209719902U discloses a remote sensing drone, comprising a drone body, a first connecting rod, a second connecting rod, a limiting block, a connecting sleeve, an elastic sleeve, and wheels. The two ends of the first connecting rod are connected to the lower surface of the drone body and the limiting block, respectively. The limiting block extends into the connecting sleeve and can slide together with the first connecting rod within the connecting sleeve. One end of the second connecting rod is connected to the connecting sleeve, and the other end is connected to the wheels. The elastic sleeve is fitted onto the outer surface of the first connecting rod. Because this remote sensing drone has the first connecting rod, second connecting rod, limiting block, connecting sleeve, and elastic sleeve on the lower surface of the drone body, it can stably stop on the ground, while improving the shock absorption effect of the drone body, thereby preventing damage to the mapping instrument on the remote sensing drone.

[0004] Existing remote sensing drones have poor cleaning performance, making it difficult to clean the cameras. Dust accumulates on the cameras, affecting their shooting quality and resulting in poor overall performance. Utility Model Content

[0005] The purpose of this invention is to provide a photogrammetric remote sensing feature data extraction and analysis device for multi-source satellite imagery, in order to solve the defect of poor cleaning effect of existing photogrammetric remote sensing feature data extraction and analysis devices for multi-source satellite imagery.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a photogrammetric remote sensing feature data extraction and analysis device for multi-source satellite imagery, comprising a remote sensing drone, wherein symmetrically mounted pitch-axis stabilized gimbals are mounted on the remote sensing drone, a barometric pressure sensor is mounted on the pitch-axis stabilized gimbal at the front end of the remote sensing drone, and satellite data receiving antennas and multispectral imaging systems are respectively mounted on the pitch-axis stabilized gimbals on both sides of the rear end of the remote sensing drone, a slot is installed at the tail of the remote sensing drone, and a data storage card is installed in the slot, and an intelligent flight control system is installed inside the remote sensing drone. A high-density battery compartment is installed at one end of the drone. Support rods are installed on both sides of the bottom of the remote sensing drone. Auxiliary structures are provided at the bottom of each support rod. A camera is installed at the bottom of the remote sensing drone. A protective structure is provided at the top of the camera. A cleaning mechanism is provided on the camera. The cleaning mechanism includes a drive motor installed at one end of the top of the camera, a rotating shaft installed at the output end of the drive motor, a brush holder installed on the rotating shaft, a limiting groove opened inside the brush holder, a telescopic spring evenly installed inside the limiting groove, and a brush installed at one end of the telescopic spring.

[0007] Preferably, the auxiliary structure includes a support foot, an adjustment groove, and an adjustment ball. The bottom end of each support rod is provided with an adjustment groove, the inside of each adjustment groove is equipped with an adjustment ball, and the bottom end of each adjustment ball is equipped with a support foot.

[0008] The above structure allows for adjustment of the angle of the support legs, enabling them to make better contact with the ground.

[0009] Preferably, the bottom end of the support foot is equipped with an anti-slip pad.

[0010] The above structure increases the friction between the support feet and the ground, thus improving the support effect.

[0011] Preferably, the adjusting ball is inserted into the support rod and forms a sliding connection with it.

[0012] With the above structure, the adjusting ball rotates along the adjusting groove, which can adjust the angle of the supporting foot.

[0013] Preferably, one end of the brush is disposed in the limiting groove, and the brush and the telescopic spring form a telescopic structure.

[0014] Through the above structure, the extension spring moves the brush, allowing the brush to come into contact with the camera.

[0015] Preferably, the protective structure includes a protective plate, a connecting shaft, a first gear, and a second gear. The connecting shaft is symmetrically installed at both ends of the bottom of the remote sensing UAV. A protective plate is installed on each connecting shaft. A first gear is installed at one end of each connecting shaft. A second gear is installed on the rotating shaft.

[0016] Preferably, the first gear meshes with the second gear.

[0017] The above structure can provide some light-blocking effect, preventing excessive light from affecting the shooting results.

[0018] The photogrammetric remote sensing feature data extraction and analysis device for multi-source satellite imagery provided by this utility model has the following advantages:

[0019] The cleaning mechanism can clean the camera to prevent dust from accumulating on it and affecting the shooting effect. The protective structure can provide some light shielding to prevent excessive light from affecting the shooting effect. The auxiliary structure can adjust the angle of the support feet to ensure better contact with the ground.

[0020] The cleaning mechanism is set up to start the motor, which drives the brush holder to rotate. The telescopic spring acts on the brush to contact the camera, thus cleaning it and preventing dust from accumulating on the camera and affecting the shooting effect.

[0021] With the protective structure in place, when the shaft rotates, the second gear drives the first gear to rotate, and the connecting shaft drives the protective plate to rotate. The protective plate rotates to above the camera to block the light and prevent the light from being too strong and affecting the shooting effect.

[0022] With the help of the auxiliary structure, when the remote sensing drone lands, the support foot pushes the adjustment ball to slide along the adjustment groove during the contact process with the ground, so as to adjust the angle of the support foot, so that the support foot can make better contact with the ground and improve the stability of the remote sensing drone during landing.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-5 The present invention provides a photogrammetric remote sensing feature data extraction and analysis device for multi-source satellite imagery, including a remote sensing UAV 1.

[0031] Reference Figures 1-5As shown, the remote sensing UAV 1 is symmetrically equipped with a pitch-axis stabilizing gimbal 3, which can effectively counteract the effects of fuselage vibration and attitude changes on the imaging equipment during UAV flight, ensuring that the multispectral imaging system 10 maintains a stable shooting angle, thereby acquiring clear and blur-free image data. This ensures image quality regardless of whether the flight is smooth or encounters airflow disturbances. A barometric pressure sensor 2 is installed on the pitch-axis stabilizing gimbal 3 at the front of the remote sensing UAV 1. Combined with satellite positioning data, it accurately measures the UAV's flight altitude, assisting the flight control system in achieving more stable altitude hold, especially in areas with significant terrain undulations. This effectively avoids shooting errors caused by altitude fluctuations, ensuring the consistency and accuracy of image data. The UAV 1 has a satellite data receiving antenna 9 and a multispectral imaging system 10 mounted on the joint-axis stabilizing gimbal 3 on both sides of its rear end. The satellite data receiving antenna 9 supports both BeiDou and GPS global satellite navigation systems, ensuring the UAV can obtain high-precision positioning information globally. This provides a guarantee for precise flight trajectory control and accurate georeferencing of image data. In areas with weak signals, the dual-mode system can automatically switch or use both signals simultaneously, improving the reliability and stability of positioning. The multispectral imaging system 10 is equipped with a 5-band sensor, capable of simultaneously acquiring image data in multiple bands, including visible light and near-infrared. This data can be used to monitor vegetation health, identify land use types, and analyze water quality. Through combined analysis of different bands, it can obtain… To acquire richer ground feature information than single-band imagery, the remote sensing UAV 1 has a slot 13 installed at its tail, on which a data storage card 14 is installed. Internally, the remote sensing UAV 1 is equipped with an intelligent flight control system 11. This system integrates multiple sensors, such as ultrasonic and infrared sensors, forming an obstacle avoidance sensor array. It can perceive the environmental information around the UAV in real time, automatically plan a safe flight path, avoid collisions with obstacles, and ensure flight safety in complex environments. Furthermore, the system supports autonomous flight mission planning. Users can pre-set parameters such as flight path, shooting point, and shooting angle through a ground control station, and the UAV can then automatically execute flight and shooting operations according to the preset mission. A high-density battery compartment 12 is installed at one end of the remote sensing drone 1, which contains a high-density battery to provide sufficient power for the drone and support long-term flight missions. Support rods 5 are installed on both sides of the bottom of the remote sensing drone 1. A camera 7 is installed at the bottom of the remote sensing drone 1, and a cleaning mechanism 6 is provided on the camera 7. The cleaning mechanism 6 includes a drive motor 604 installed at the top end of the camera 7, a rotating shaft 603 installed at the output end of the drive motor 604, a brush holder 601 installed on the rotating shaft 603, a limiting groove 605 opened inside the brush holder 601, a telescopic spring 606 evenly installed inside the limiting groove 605, and a brush 602 installed at one end of the telescopic spring 606, with one end of the brush 602 set in the limiting groove 605.The brush 602 and the telescopic spring 606 constitute a telescopic structure.

[0032] The remote sensing drone 1 integrates advanced multispectral imaging technology, satellite data receiving technology, and intelligent flight control technology, enabling it to efficiently and accurately acquire high-quality remote sensing data in various complex environments. When in use, the drive motor 604 starts, the rotating shaft 603 drives the brush holder 601 to rotate, and the telescopic spring 606 acts to make the brush 602 contact with the camera 7 to clean it, thus preventing dust from accumulating on the camera 7 and affecting the shooting effect.

[0033] Reference Figures 1-3 As shown, a protective structure 8 is provided at the top of the camera 7. The protective structure 8 includes a protective plate 801, a connecting shaft 802, a first gear 803 and a second gear 804. The connecting shaft 802 is symmetrically installed at both ends of the bottom of the remote sensing drone 1. A protective plate 801 is installed on each connecting shaft 802. A first gear 803 is installed on one end of each connecting shaft 802. A second gear 804 is installed on the rotating shaft 603. The first gear 803 and the second gear 804 mesh.

[0034] When the drive motor 604 starts and the rotating shaft 603 rotates, the second gear 804 drives the first gear 803 to rotate, and the connecting shaft 802 drives the protective plate 801 to rotate. The protective plate 801 rotates to the top of the camera 7 to block the light and prevent the light from being too strong and affecting the shooting effect.

[0035] Reference Figure 1 , Figure 2 and Figure 5 As shown, each support rod 5 has an auxiliary structure 4 at its bottom end. The auxiliary structure 4 includes a support foot 401, an adjustment groove 402, and an adjustment ball 403. Each support rod 5 has an adjustment groove 402 at its bottom end. An adjustment ball 403 is installed inside the adjustment groove 402. The adjustment ball 403 is inserted into the support rod 5 and forms a sliding connection with it. Each adjustment ball 403 has a support foot 401 at its bottom end. An anti-slip pad 4011 is installed at the bottom end of the support foot 401 to increase the friction between the support foot 401 and the ground and improve the support effect.

[0036] When the remote sensing drone 1 lands, during the process of the support foot 401 contacting the ground, the support foot 401 pushes the adjustment ball 403 to slide along the adjustment groove 402 to adjust the angle of the support foot 401 so that the support foot 401 can make better contact with the ground and improve the stability of the remote sensing drone 1 during landing.
