Description

Technical Field

[0001] This invention relates to the field of computer vision technology, specifically to a multi-view stitching method and camera. Background Technology

[0002] Multi-view stitching cameras are an innovative image acquisition and digital playback technology. This system consists of multiple cameras that work together through a carefully designed mechanical structure and ingenious operating mechanism to acquire and precisely stitch together multi-view images. In terms of multi-view stitching methods, advanced image registration and fusion algorithms are used. Based on the precise relative positions of the cameras and the feature information of the acquired images, the images captured by each camera are seamlessly stitched together to form a complete image with a wide viewing angle, high resolution, and rich detail, providing a solid data foundation for various subsequent applications. This multi-view stitching method and camera have broad application prospects in computer vision, surveying and mapping, industrial inspection, virtual reality, and other fields, enabling various industries to work more efficiently and accurately and acquire more valuable visual information.

[0003] However, existing multi-lens stitching cameras often need to operate in various complex environments, such as outdoor sandstorms and dusty environments, or industrial production sites with a lot of dust and impurities. Most multi-lens stitching cameras lack effective lens protection measures, and the lenses are directly exposed to the outside, making them susceptible to dust, moisture, and physical impact damage. Once the lens surface is covered with too much dust, it will not only affect the light transmittance, resulting in blurry and dark images, but also, due to the lack of a suitable protective mechanism, improper wiping operations may cause scratches on the lens surface, affecting the lens image quality and lifespan, thus affecting the overall working effect and reliability of the multi-lens stitching camera, and reducing the lifespan of the multi-lens lens. Summary of the Invention

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a multi-view stitching method and camera, which solves the problems of existing multi-view stitching cameras lacking effective lens protection measures, being prone to lens contamination and damage, having unstable protection status, being easily damaged during cleaning, and affecting image quality and overall operational reliability.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a multi-lens stitching camera, comprising a frame mounted on the top of a support, wherein a lens is installed inside the frame; further comprising a movable component for protecting the surface of the lens; a fixing component for restricting the lens during protection; and a cleaning component for wiping the surface of the lens; the movable component comprising: a fixing frame mounted on the outer wall of the frame, a rack fixedly mounted on the outer side of the fixing frame, a sliding plate slidably connected inside the fixing frame, a connecting plate fixedly mounted on the top of the sliding plate, a rotating shaft rotatably connected to the inner side of the sliding plate, a gear fixedly mounted on the outer side of the rotating shaft, a protective block fixedly mounted on the surface of the rotating shaft, and a spiral spring fixedly mounted on the surface of the rotating shaft. On the outer wall of the plate, a fixed plate is installed on the top of the frame. A turntable is rotatably connected to the top of the fixed plate. A sliding rod is slidably connected inside the turntable. A movable plate is hinged to the bottom of the sliding rod. The movable plate passes through the fixed plate. A vertical plate is fixedly installed at the bottom of the movable plate. The vertical plate is fixedly installed on the top of the connecting plate. The fixing assembly includes: a connecting ring, which is fixedly installed on the top of the fixed plate. A positioning block is fixedly installed inside the connecting ring. A rotating column is fixedly installed on the top of the turntable. A control rod is fixedly installed on the surface of the rotating column. A telescopic rod is fixedly installed on the top of the control rod. The telescopic rod is fixedly installed on the top of the turntable. A movable spring is fixedly installed inside the telescopic rod. An insert plate is fixedly installed on the surface of the control rod. The insert plate is inserted into the inside of the positioning block.

[0008] Preferably, the cleaning assembly includes: a rotating shaft rotatably connected to the outer wall of the frame; a sliding rod passing through the interior of the rotating shaft; a return spring fixedly installed on the inner side of the sliding rod; a trigger rod slidably connected to the surface of the rotating shaft; the other end of the trigger rod fixedly installed on the outer side of the sliding rod; the trigger rod slidably connected to the inner side of the fixed frame; a bevel gear one fixedly installed on the surface of the rotating shaft; a bevel gear two meshing on the outer side of the bevel gear one; a threaded rod fixedly installed on the outer side of the bevel gear two; the threaded rod rotatably connected to the inner wall of the fixed frame; a cleaning block threadedly connected to the surface of the threaded rod; and the cleaning block slidably connected to the inner side of the fixed frame.

[0009] Preferably, the turntable surface has a crescent groove, the trigger rod has a U-shaped cross-section, and the rotating shaft surface has an arc-shaped groove.

[0010] Preferably, the active components are provided in six groups, and all six groups of active components are disposed on the surface of the lens.

[0011] A multi-view stitching method further includes the following steps:

[0012] First, lift the control lever, which will cause the telescopic rod to extend. The movable spring will be pulled up, and the insert plate fixed on the surface of the control lever will move up and away from the position restricted by the positioning block fixed inside the connecting ring. At this time, rotate the turntable. When the protective block is in place, release the control lever. Under the elastic force of the movable spring, the telescopic rod will shorten, and the insert plate will be reinserted into the positioning block.

[0013] When the turntable rotates, it is rotatably connected to the top of the fixed plate, and a sliding rod is slidably connected inside the turntable. A movable plate is hinged to the bottom of the sliding rod, which passes through the fixed plate and is connected to the vertical plate. The vertical plate is fixed to the top of the connecting plate. Therefore, when the turntable rotates, it will move towards the outer wall of the turntable by abutting the sliding rod through the crescent groove on its surface. When the sliding rod moves, it will drive the movable plate and the vertical plate to move in the same direction as the sliding rod. When the vertical plate moves, it will drive the connecting plate at the bottom to move. When the connecting plate moves, it will drive the slide to slide inside the fixed frame. A gear is fixed on the rotating shaft rotatably connected inside the slide, and a rack is fixed on the outside of the fixed frame. When the slide moves, the gear will mesh with the rack. At the same time, one end of the spiral spring fixed on the surface of the rotating shaft is fixed to the outer wall of the slide. As the gear rolls on the rack, the rotating shaft starts to rotate, the spiral spring is further twisted, storing elastic potential energy, and the protective block on the rotating shaft moves downward accordingly.

[0014] When the protective block moves towards the surface of the fixed frame, it also pushes the sliding rod to slide inside the rotating shaft. When the sliding rod slides, it drives the trigger rod to slide. One end of the trigger rod slides on the surface of the rotating shaft. Since its other end is fixedly connected to the outside of the sliding rod, and a return spring is fixed inside the sliding rod, the trigger rod will compress the return spring when it moves and slide in the arc groove opened on the surface of its rotating shaft. This drives the rotating shaft to rotate. When the rotating shaft rotates, the bevel gear one fixed on its surface also rotates. Bevel gear one meshes with bevel gear two, driving bevel gear two to rotate. The threaded rod fixed on the outside of bevel gear two also rotates. The threaded rod is threadedly connected to the cleaning block, and the cleaning block slides inside the fixed frame. Driven by the rotation of the threaded rod, the cleaning block will make a linear reciprocating motion along the inside of the fixed frame.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a multi-view stitching method and camera, which has the following beneficial effects:

[0017] 1. This multi-lens stitching method and camera utilize movable components. Rotating the turntable moves a sliding rod via its crescent-shaped groove, driving a series of interconnected components. This causes the sliding plate to slide, and gears and racks mesh to transmit power. The rotating shaft then moves the protective block downwards. This downward movement of the protective block prevents dust from easily adhering to the lens, affecting image formation and damaging the lens. The protective block isolates dust, reducing its contact with the lens, protecting it from physical damage and contamination, extending lens lifespan, and ensuring normal camera operation.

[0018] 2. This multi-lens stitching method and camera utilizes a fixed component setup. By raising the control lever, the relevant components can be moved to release the restriction of the insert plate. After rotating the turntable to adjust the position of the protective block, the control lever is released, and the insert plate resets under the action of the spring and is inserted into the positioning block for fixation. This prevents the protective block from being easily displaced due to vibration or other reasons, which could potentially scratch the lens. The insertion of the insert plate can fix the protective block, ensuring its stable protection of the lens and improving the continuity and stability of protection.

[0019] 3. This multi-lens stitching method and camera utilizes a cleaning component setup. The movement of the protective block pushes the sliding rod, which in turn drives the trigger rod and other components to move. Through the transmission of bevel gear one and gear two, the threaded rod rotates, driving the cleaning block to make linear reciprocating motion along the fixed frame. This can wipe the surface of the lens, preventing the accumulation of dirt from affecting the image quality, ensuring the imaging effect, and improving the working efficiency and reliability of the multi-lens stitching camera.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-8 As shown, a multi-view stitching camera includes a frame 2 set at the top of a bracket 1, and a lens 3 is installed inside the frame 2.

[0031] It also includes active component 4; used to protect the surface of lens 3;

[0032] Fixing component 5 is used to restrict the lens 3 when it is being protected;

[0033] Cleaning component 6 is used to wipe the surface of lens 3;

[0034] First, the active component 4 includes: a fixed frame 41, which is installed on the outer wall of the frame 2. A rack 42 is fixedly installed on the outer side of the fixed frame 41. A slide plate 43 is slidably connected inside the fixed frame 41. A connecting plate 44 is fixedly installed on the top of the slide plate 43. A rotating shaft 45 is rotatably connected to the inner side of the slide plate 43. A gear 46 is fixedly installed on the outer side of the rotating shaft 45. A protective block 47 is fixedly installed on the surface of the rotating shaft 45. A spiral spring 48 is fixedly installed on the surface of the rotating shaft 45. The spiral spring 48 is fixedly installed on the outer wall of the slide plate 43. The spiral spring 48 on the surface of the rotating shaft 45 can achieve the reset effect of the lens 3 when the protective block 47 swings downward during the rotation of the rotating shaft 45.

[0035] Secondly, a fixed plate 49 is installed on the top of the frame 2. A turntable 410 is rotatably connected to the top of the fixed plate 49. A slide rod 411 is slidably connected inside the turntable 410. A movable plate 412 is hinged to the bottom of the slide rod 411. The movable plate 412 passes through the fixed plate 49. A vertical plate 413 is fixedly installed at the bottom of the movable plate 412. The vertical plate 413 is fixedly installed on the top of the connecting plate 44. The movable plate 412 can be driven to slide laterally inside the fixed plate 49 when the slide rod 411 slides through the movable plate 412 hinged to the bottom of the slide rod 411.

[0036] Furthermore, the fixing component 5 includes: a connecting ring 51, which is fixedly installed on the top of the fixing plate 49; a positioning block 52 is fixedly installed on the inner side of the connecting ring 51; a rotating column 53 is fixedly installed on the top of the turntable 410; a control rod 54 is fixedly installed on the surface of the rotating column 53; a telescopic rod 55 is fixedly installed on the top of the control rod 54; the telescopic rod 55 is fixedly installed on the top of the turntable 410; a movable spring 56 is fixedly installed inside the telescopic rod 55; and an insert plate 57 is fixedly installed on the surface of the control rod 54. The insert plate 57 is inserted into the inner side of the positioning block 52. The movable spring 56 inside the telescopic rod 55 can achieve the effect of resetting after the telescopic rod 55 is stretched or compressed.

[0037] Furthermore, the cleaning component 6 includes: a rotating shaft 61, which is rotatably connected to the outer wall of the frame 2; a sliding rod 62 passing through the inside of the rotating shaft 61; a return spring 63 fixedly installed inside the sliding rod 62; a trigger rod 64 slidably connected to the surface of the rotating shaft 61; the other end of the trigger rod 64 fixedly installed outside the sliding rod 62; the trigger rod 64 slidably connected to the inner side of the fixed frame 41; a bevel gear 65 fixedly installed on the surface of the rotating shaft 61; a bevel gear 66 meshing with the outer side of the bevel gear 65; a threaded rod 67 fixedly installed on the outer side of the bevel gear 66; the threaded rod 67 rotatably connected to the inner wall of the fixed frame 41; a cleaning block 68 threadedly connected to the surface of the threaded rod 67; and the cleaning block 68 slidably connected to the inner side of the fixed frame 41. The return spring 63 inside the sliding rod 62 enables the sliding rod 62 to reset when it is pressed by the protective block 47.

[0038] Finally, a crescent groove 460 is provided on the surface of the turntable 410. The crescent groove 460 on the surface of the turntable 410 allows the turntable 410 to slide against the slide rod 411 when it rotates. The cross-section of the trigger rod 64 is U-shaped. The U-shaped trigger rod 64 can improve the connection between the trigger rod 64 and the rotating shaft 61. An arc groove 610 is provided on the surface of the rotating shaft 61. The arc groove 610 on the surface of the rotating shaft 61 allows the rotating shaft 61 to rotate when the trigger rod 64 slides.

[0039] There are six sets of active components 4, and all six sets of active components 4 are set on the surface of the lens 3.

[0040] A multi-view stitching method further includes the following steps:

[0041] Step 1: First, rotate the turntable 410. Since the turntable 410 is rotatably connected to the top of the fixed plate 49, and a sliding rod 411 is slidably connected inside the turntable 410, with a movable plate 412 hinged to the bottom of the sliding rod 411. The movable plate 412 passes through the fixed plate 49 and is connected to the vertical plate 413, which is fixed to the top of the connecting plate 44. Therefore, when the turntable 410 rotates, it will move closer to the outer wall of the turntable 410 by abutting the sliding rod 411 through the crescent groove 460 on its surface. When the sliding rod 411 moves, it will drive the movable plate 412 and the vertical plate 413 to move in the same direction as the sliding rod 411. When the vertical plate 413 moves, it will drive the connecting plate 44 at the bottom to move. When the connecting plate 44 moves, it causes the sliding plate 43 to slide inside the fixed frame 41. A gear 46 is fixed on the rotating shaft 45 connected to the inner side of the sliding plate 43, while a rack 42 is fixed on the outer side of the fixed frame 41. When the sliding plate 43 moves, the gear 46 meshes with the rack 42. At the same time, one end of the spiral spring 48 fixed to the surface of the rotating shaft 45 is fixed to the outer wall of the sliding plate 43. As the gear 46 rolls on the rack 42, the rotating shaft 45 begins to rotate, and the spiral spring 48 is further twisted, storing elastic potential energy. The protective block 47 on the rotating shaft 45 moves downward accordingly to prevent dust from easily adhering to the surface of the lens 3 when using the camera in outdoor or dusty industrial environments. The cover can effectively isolate dust and prevent it from accumulating on the lens 3. If too much dust is on the lens 3, it will not only affect the light transmittance, causing the shooting image to become blurry and dark, but may also cause new damage such as scratches when cleaning the lens 3 due to improper wiping. The presence of the protective block 47 can greatly reduce the chance of dust coming into contact with the lens 3, protect the lens 3, prevent the lens 3 from being damaged by external physical damage, and prevent dust and other impurities from contaminating the lens 3, thereby improving the protection of the multi-lens 3 and extending the service life of the multi-lens 3.

[0042] Step Two: Raise the control lever 54. The control lever 54 causes the telescopic lever 55 to extend, the movable spring 56 is pulled up, and the insert plate 57 fixed on the surface of the control lever 54 moves up, leaving the position restricted by the positioning block 52 fixed inside the connecting ring 51. At this time, rotate the turntable 410. When the protective block 47 is in place, release the control lever 54. Under the elastic force of the movable spring 56, the telescopic lever 55 shortens, and the insert plate 57 re-inserts into the inside of the positioning block 52. This prevents the protective block 47 from shifting due to slight vibrations or accidental contact during the use of the multi-lens stitching camera. For example, when the camera is in transport, placed on an unstable platform, or when people are walking around at the shooting location, vibrations caused by these factors are transmitted to the camera. If the protective block 47 shifts, it will not be able to protect the lens 3 effectively and may even scratch the surface of the lens 3, causing damage to the lens 3. Reinserting the positioning block 52 into the inner side can firmly fix the relevant components, keep the protective block 47 in the predetermined position, avoid such accidental movement, and improve the continuity and stability of the protection of the multi-lens 3.

[0043] Step 3: When the protective block 47 moves towards the surface near the fixed frame 41, it also pushes the sliding rod 62 to slide inside the rotating shaft 61. When the sliding rod 62 slides, it will drive the trigger rod 64 to slide. One end of the trigger rod 64 slides on the surface of the rotating shaft 61. Since its other end is fixedly connected to the outside of the sliding rod 62, and a return spring 63 is fixed inside the sliding rod 62, when the trigger rod 64 moves, it will compress the return spring 63 and slide at the arc-shaped groove 610 opened on the surface of its rotating shaft 61. This will drive the rotating shaft 61 to rotate. When the rotating shaft 61 rotates, the bevel gear 65 fixed on its surface will also rotate. The bevel gear 65 meshes with the bevel gear 66, driving the bevel gear 66 to rotate. The threaded rod 67 fixed on the outside also rotates. The threaded rod 67 is threadedly connected to the cleaning block 68, and the cleaning block 68 slides inside the fixed frame 41. Driven by the rotation of the threaded rod 67, the cleaning block 68 will make a linear reciprocating motion along the inside of the fixed frame 41 to prevent the accumulation of dirt on the surface of the lens 3 from affecting the image quality. During the use of the camera, the surface of the lens 3 will inevitably be contaminated with dust, moisture, oil and other dirt. If these dirt accumulates for a long time and is not cleaned in time, it will gradually increase the scattering and refraction of the surface of the lens 3, so that the light entering the lens 3 cannot propagate along the normal light path, which will lead to problems such as blurry images, reduced contrast and color distortion, seriously affecting the image quality. The linear reciprocating motion of the cleaning block 68 can wipe away the dirt on the surface of the multi-lens 3 in time, prevent the dirt from accumulating, ensure a clear and stable imaging effect, and improve the working efficiency and reliability of the multi-lens stitching camera.

The bevel gear one (65) meshes with the bevel gear two (66), causing the bevel gear two (66) to rotate. The threaded rod (67) fixed on the outside of the bevel gear two (66) also rotates. The threaded rod (67) is threadedly connected to the cleaning block (68), and the cleaning block (68) slides inside the fixed frame (41). Driven by the rotation of the threaded rod (67), the cleaning block (68) will make a linear reciprocating motion along the inside of the fixed frame (41).
