Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) target recognition technology, specifically to a multi-camera panoramic stitching and target recognition device. Background Technology

[0002] The multi-camera panoramic stitching and target recognition device is a high-performance airborne observation system that integrates multispectral imaging, panoramic stitching, and artificial intelligence target recognition. This device typically uses multi-camera systems (such as visible light, infrared, and ultra-wide-angle cameras) as its core sensors. Through complex algorithms, it stitches images of overlapping areas from multiple cameras into a seamless panoramic image in real time. It then uses a built-in AI image processing board to analyze the panoramic video stream in real time, automatically detecting, recognizing, and tracking specific targets. This improves the efficiency of wide-area perception and intelligent judgment for drones in complex scenarios such as border and coastal patrols, disaster relief, and smart city management.

[0003] However, to facilitate adjusting the shooting angle of multi-view cameras, existing multi-view cameras and their angle driving mechanisms are usually integrated into an electro-optical pod. The pod's top mounting plate is then bolted to the bottom of the drone. However, the electro-optical pod experiences significant air resistance as it ascends, descends, and flies with the drone. This air resistance exerts pressure on the bolts connecting the pod to the drone over time, causing the bolts to deform and break, ultimately leading to the pod detaching and being damaged. Therefore, there is an urgent need for a robust multi-view camera panoramic stitching and target recognition device. Utility Model Content

[0004] To overcome the aforementioned deficiencies in the prior art, this application provides a multi-view camera panoramic stitching and target recognition device. This device uses toothed engagement to assemble an optoelectronic pod onto the bottom of a drone, preventing the pod from being affected by air resistance and causing it to sway at the bottom of the drone, thus preventing deformation and breakage of the bolts. This avoids damage to the optoelectronic pod due to bolt deformation or breakage, improving the stability of the optoelectronic pod installation and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A multi-view camera panoramic stitching and target recognition device includes: a drone and an optoelectronic pod mounted on its bottom mounting base. A connecting plate is provided at the top of the optoelectronic pod, and a mounting plate is provided on the lower end face of the mounting base. The connecting plate is tightly attached to the lower end face of the mounting plate. An anti-slip component is provided between the mounting plate and the connecting plate. The anti-slip component includes an upper anti-slip plate and a lower anti-slip plate. The upper anti-slip plate is located on the lower end face of the mounting plate, and the lower anti-slip plate is located on the upper end face of the connecting plate and engages with the upper anti-slip plate to prevent the connecting plate from loosening or slipping. Locking bolts are provided at the four corners of the mounting plate and the connecting plate. The locking bolts are threaded inside the mounting plate and the connecting plate for locking and limiting.

[0007] Preferably, the upper anti-slip plate is composed of two sets of first longitudinal teeth and first transverse teeth that are vertically distributed. The two sets of first longitudinal teeth are longitudinally arranged at the front and rear ends of the lower end face of the mounting plate, and the two sets of first transverse teeth are transversely arranged at the left and right ends of the lower end face of the mounting plate.

[0008] Preferably, the lower anti-slip plate is composed of two sets of vertically distributed second longitudinal teeth and second transverse teeth spliced ​​together. The two sets of second longitudinal teeth are longitudinally arranged at the front and rear ends of the upper surface of the connecting plate and mesh with the first longitudinal teeth. The two sets of second transverse teeth are transversely arranged at the left and right ends of the upper surface of the connecting plate and mesh with the first transverse teeth.

[0009] Preferably, the mounting plate and the connecting plate have upper threaded holes and lower threaded holes at their four corners, and the locking bolts are threaded into the upper threaded holes and lower threaded holes.

[0010] Preferably, the locking bolt is composed of an upper bolt and a lower bolt joined together. The upper bolt is located above the mounting plate and passes through the upper threaded hole and is threaded inside the lower threaded hole. The lower bolt is located below the connecting plate and is threaded inside the lower threaded hole and tightened on the lower end face of the upper bolt. The surface thread direction of the lower bolt is opposite to that of the upper bolt.

[0011] Preferably, the upper end face of the lower bolt is provided with an extension screw, and a slot is opened at the position corresponding to the extension screw on the lower end face of the upper bolt, with the extension screw extending into the interior of the slot.

[0012] Preferably, the inner wall of the empty slot is provided with a threaded groove, and the extension screw is threadedly installed inside the empty slot through the threaded groove.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] By setting anti-slip components, the connecting plate can be attached to the lower end face of the mounting plate. The longitudinal and transverse teeth on the upper anti-slip plate and the lower protective plate engage to limit the position of the connecting plate, preventing the electro-optical pod from being affected by air resistance and causing the connecting plate to sway at the bottom of the drone. This applies pressure to the bolts, avoiding deformation and breakage of the bolts due to pressure, which could lead to the electro-optical pod falling off and being damaged. This improves the stability of the electro-optical pod installation and ensures the target recognition effect of the multi-view panoramic acquisition machine. Attached Figure Description

Detailed Implementation

[0022] Combination Figures 1-5As shown in this embodiment, a multi-view camera panoramic stitching and target recognition device includes: a drone 1 and an optoelectronic pod 2 mounted on its bottom mounting base 11. The top of the optoelectronic pod 2 is provided with a connecting plate 21, and the lower end face of the mounting base 11 is provided with a mounting plate 12. The connecting plate 21 is tightly attached to the lower end face of the mounting plate 12. The locking bolts 3 can be installed in the upper threaded holes 121 and the lower threaded holes 211 on the mounting plate 12 and the connecting plate 21 to complete the assembly and fixation of the mounting plate 12 and the connecting plate 21, thereby realizing the assembly of the optoelectronic pod 2 and the drone 1.

[0023] In this embodiment, an anti-slip assembly is provided between the mounting plate 12 and the connecting plate 21. The anti-slip assembly includes an upper anti-slip plate and a lower anti-slip plate. The upper anti-slip plate is composed of two sets of vertically distributed first longitudinal teeth 13 and first transverse teeth 14 spliced ​​together, and the lower anti-slip plate is composed of two sets of vertically distributed second longitudinal teeth 22 and second transverse teeth 23 spliced ​​together. The connecting plate 21 can be fixed to the lower end face of the mounting plate 12, so that the first longitudinal teeth 13 and the first transverse teeth 14 can be inserted and engaged with the second longitudinal teeth 22 and the second transverse teeth 23 respectively. The tooth engagement prevents the connecting plate 21 from sliding laterally, longitudinally, or obliquely on the lower end face of the mounting plate 12, limits the position of the connecting plate 21, and prevents the photoelectric pod 2 from being affected by air resistance, causing the connecting plate 21 to shake at the bottom of the drone 1 and apply pressure to the locking bolt 3, thereby protecting the locking bolt 3.

[0024] In this embodiment, the locking bolt 3 is composed of an upper bolt 31 and a lower bolt 32. The lower bolt 32 is screwed onto the lower end face of the upper bolt 31, and an extension screw 321 is provided on the upper end face of the lower bolt 32. A slot is opened at the position corresponding to the extension screw 321 on the lower end face of the upper bolt 31, and the extension screw 321 extends into the interior of the slot. The extension screw 321 is installed into the slot through the threaded groove 311, and the upper bolt 31 and the lower bolt 32 are assembled into a whole. This prevents the upper bolt 31 and the lower bolt 32 from loosening on the mounting plate 12 and the connecting plate 21 due to the vibration of the UAV 1, and improves the stability of the locking bolt 3 installation.

[0025] In this embodiment, since the surface threads of the lower bolt 32 and the upper bolt 31 are opposite, the upper bolt 31 and the lower bolt 32 with opposite thread directions can be screwed into the upper threaded hole 121 and the lower threaded hole 211 respectively. The nuts of the upper bolt 31 and the lower bolt 32 are screwed onto the end faces of the mounting plate 12 and the connecting plate 21 respectively. The mounting plate 12 and the connecting plate 21 are clamped between the two nuts for limiting the connection plate 21 and the mounting plate 12, thereby preventing the connecting plate 21 from separating from the mounting plate 12 and further improving the stability of the assembly of the optoelectronic pod 2 and the UAV 1.

[0026] The working principle of this utility model is as follows: The multi-view camera panoramic stitching and target recognition device proposed in this application sets an anti-slip component between the mounting plate 12 and the connecting plate 21. The connecting plate 21 can be fixed to the lower end face of the mounting plate 12 by the locking bolt 3. The first longitudinal tooth 13 and the first transverse tooth 14 are respectively inserted and meshed with the second longitudinal tooth 22 and the second transverse tooth 23. The meshing of the teeth prevents the connecting plate 21 from sliding laterally, longitudinally or obliquely on the lower end face of the mounting plate 12, limits the position of the connecting plate 21, and prevents the photoelectric pod 2 from being affected by air resistance, causing the connecting plate 21 to shake at the bottom of the drone 1 and apply pressure to the locking bolt 3. This avoids the locking bolt 3 from deforming or breaking due to pressure, which would cause the photoelectric pod 2 to fall off and be damaged. This improves the stability of the installation of the photoelectric pod 2 and ensures the target recognition effect of the multi-view camera panoramic acquisition machine.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
