Description

Technical Field

[0001] This utility model relates to the field of video surveillance technology, and in particular to a lens mounting assembly and a panoramic stitching camera. Background Technology

[0002] With the rapid development of smart cities, smart tourism, and public safety, the application scenarios of surveillance cameras have expanded from traditional indoor and outdoor general monitoring to complex environments with higher demands for panoramic views, such as omnidirectional traffic monitoring at transportation hubs, panoramic navigation monitoring in scenic spots, and blind-spot-free security protection for large venues. Against this backdrop, 360° panoramic stitching cameras, due to their ability to achieve all-around, blind-spot-free imaging through simultaneous acquisition from multiple lenses and algorithmic stitching, are gradually becoming core equipment in these scenarios.

[0003] However, the actual deployment environments for panoramic stitching cameras are complex and diverse. Some devices need to be suspended at high altitudes (such as the top of streetlights or the dome of a venue), while others need to be installed at low altitudes (such as shop entrances or scenic area fences). The shooting angle requirements differ significantly at different heights: high-altitude scenes require the lens to tilt upwards to cover a wider horizontal field of view, while low-altitude scenes require the lens to tilt downwards to capture ground details. Existing panoramic stitching cameras cannot meet the multi-angle shooting needs at different heights, forcing users to deploy multiple additional devices in complex scenarios, increasing hardware costs and maintenance complexity. Utility Model Content

[0004] This utility model provides a lens mounting assembly and a panoramic stitching camera to solve the above-mentioned technical defects in the prior art. It can not only adapt to the multi-angle shooting needs at different heights by replacing the mounting brackets with different tilt angles, but also reduce the difficulty and cost of stitching calibration, and improve the consistency and yield of the products.

[0005] The first aspect of this utility model provides a lens mounting assembly, comprising:

[0006] Mounting base, which can be detachably mounted on the panoramic stitching camera;

[0007] Multiple mounting brackets are arranged in a circular array along the circumference of the mounting base.

[0008] Multiple lens modules are provided, each corresponding to one of the multiple mounting brackets. Each lens module is detachably mounted to the corresponding mounting bracket, and the axis of each lens module is parallel to the center line of the mounting bracket.

[0009] According to the lens mounting assembly provided by this utility model, the angle between the support plane of the mounting bracket and the axis of the mounting base is negatively correlated with the height of the captured image, wherein: the height of the captured image is the vertical field of view coverage in the image.

[0010] According to the lens mounting assembly provided by this utility model, each of the mounting brackets includes:

[0011] The mounting body is detachably connected to the mounting base;

[0012] A support body is connected to the mounting body and is set at an angle to the mounting body. The support body has a mounting groove.

[0013] The lens module is embedded in the mounting slot and fixedly connected to the support body.

[0014] According to the lens mounting assembly provided by this utility model, the support body is also provided with a dotted groove and a positioning hole;

[0015] The adhesive grooves are located on opposite sides of the mounting groove, and the lens module is bonded and fixed to the support body; the positioning holes are provided on the groove wall of the mounting groove for positioning the lens module.

[0016] According to the lens mounting assembly provided by this utility model, a heat-conducting body is provided on the side of the support body away from the mounting body, and a heating film is provided on the heat-conducting body.

[0017] According to the lens mounting assembly provided by this utility model, a reinforcing member is provided between the mounting body and the supporting body;

[0018] The supporting body is provided with fixing holes, which are used to fix the lens module.

[0019] A second aspect of this utility model provides a panoramic stitching camera, comprising:

[0020] The housing assembly has an internal cavity and multiple viewing windows are provided on the housing assembly. Each viewing window is connected to the cavity and the multiple viewing windows are arranged in a circular array along the circumference of the housing assembly.

[0021] Multiple window components are correspondingly disposed in each of the stated window windows, and each stated window component is detachably connected to the housing component; and includes:

[0022] The lens mounting assembly according to any one of the claims, wherein the lens mounting assembly is disposed in the receiving cavity, and the position of the lens module corresponds to the position of the window assembly.

[0023] According to the panoramic stitching camera provided by this utility model, each of the viewport components includes:

[0024] Window unit;

[0025] A viewing window glass is fixedly mounted on the viewing window unit;

[0026] A window pressure plate is detachably connected to the housing assembly and abuts against the window unit, thereby sealing the window unit against the edge of the window.

[0027] According to the panoramic stitching camera provided by this utility model, the viewing window unit includes:

[0028] The window housing has an interconnected mounting section and a window body;

[0029] A sealing element is fitted into the mounting portion. The sealing element has a plurality of anti-detachment portions distributed circumferentially. Each anti-detachment portion is arranged around the edge of the mounting portion and holds the edge of the mounting portion tightly.

[0030] According to the panoramic stitching camera provided by this utility model, the housing assembly includes:

[0031] Shell body;

[0032] A cover is placed on the housing body and detachably connected to the housing body, the cover and the housing body enclosing the receiving cavity;

[0033] The plurality of viewing windows are disposed on the housing body and are distributed in a circular array along the circumference of the housing body.

[0034] The lens mounting assembly provided by this utility model includes multiple mounting brackets arranged in a circular array along the circumference of the mounting base. Each mounting bracket is detachably connected to the mounting base, and the supporting plane of each mounting bracket forms an angle with the reference mounting plane of the mounting base. Multiple lens modules are arranged one-to-one with the multiple mounting brackets, and each lens module is detachably mounted to its corresponding mounting bracket, with the axis of each lens module parallel to the center line of the mounting bracket. By replacing the mounting brackets with different tilt angles, it can adapt to the multi-angle shooting needs at different heights: when the panoramic stitching camera is suspended in a high-altitude environment, a mounting bracket with a larger tilt angle can be selected to tilt the optical axis of the lens module upward, expanding the coverage of the high-altitude image; when the panoramic stitching camera is suspended in a low-altitude environment, a mounting bracket with a smaller tilt angle can be selected to tilt the optical axis of the lens module downward, preventing the high-altitude image from obscuring low-altitude details.

[0035] Furthermore, the core challenge of panoramic stitching cameras lies in the stitching accuracy of multiple lens modules. This requires ensuring minimal matching of feature points in the overlapping areas of adjacent lens modules, and the key to stitching calibration is the consistency of the relative positions (including spacing, pitch angle, and yaw angle) of each lens module. Otherwise, problems such as mismatched feature points in overlapping areas, image ghosting, or local blurring can easily occur during the stitching process, severely affecting the integrity and timeliness of the panoramic image.

[0036] The mounting base in this embodiment provides a unified reference mounting plane for the lens modules. All lens modules are fixed to this reference mounting plane by mounting brackets, ensuring that the central axes of each lens module are located on the same circumference, with the center of the circle being the center of the mounting base. This avoids positional deviations of the lens modules due to uneven mounting surfaces. Furthermore, the circumferential array distribution of the mounting brackets ensures consistency in the horizontal spacing and initial angle of each lens module. During production, all lens modules can be installed onto the mounting base at once using the mounting brackets. Synchronous debugging of multiple lens modules can be completed by rotating the mounting base, eliminating the need for individual calibration of each lens module. This reduces the difficulty and cost of splicing and calibration, improving product consistency and yield.

[0037] The panoramic stitching camera provided by this utility model, because it includes the above-mentioned lens mounting assembly, possesses all the advantages of the above-mentioned lens mounting assembly. Attached Figure Description

[0056] Figure 1 This is an exploded view of the lens mounting assembly provided in an embodiment of the present invention. Figure 2 This is a front view of the lens mounting assembly provided in this embodiment of the utility model.

[0057] See Figure 1 and Figure 2 This utility model embodiment provides a lens mounting assembly 30, which includes a circular or nearly circular mounting base 31, multiple mounting brackets 32 and multiple lens modules 33, wherein the mounting base 31 and the multiple mounting brackets 32 can all be made of aluminum alloy.

[0058] The mounting base 31 can be detachably mounted to the housing assembly 10 of the panoramic stitching camera using fasteners such as screws or bolts. The mounting base 31 provides a unified reference mounting plane for multiple lens modules 33, ensuring that the central axis of each lens module 33 is located on the same circumference, and unifying the mounting position of each lens module 33.

[0059] Multiple mounting brackets 32 can be configured according to the number of lens modules 33. For example, if there are 8 lens modules 33, then there are 8 mounting brackets 32; if there are 6 lens modules 33, then there are 6 mounting brackets 32; and if there are 4 lens modules 33, then there are 4 mounting brackets 32. The multiple mounting brackets 32 are arranged in a circular array along the circumference of the mounting base 31, and each mounting bracket 32 ​​is detachably connected to the mounting base 31. The supporting plane on the mounting bracket 32 ​​for mounting the lens module 33 is set at an angle to the reference mounting plane on the mounting base 31. For example, the angle between the supporting plane on the mounting bracket 32 ​​for mounting the lens module 33 and the reference mounting plane on the mounting base 31 can be 15°, 20°, 25°, 30°, 35°, 40°, 45°, or 50°, etc., specifically selected adaptively according to the usage scenario of the lens module 33 (i.e., suspended in a high-altitude or low-altitude environment).

[0060] The supporting plane on the mounting bracket 32 ​​for mounting the lens module 33 can be understood as the upper surface of the mounting bracket 32, and the lens module 33 is fixed on this upper surface. The reference mounting plane on the mounting base 31 can be understood as the upper surface of the mounting base 31, and the mounting bracket 32 ​​is mounted on this upper surface.

[0061] Multiple lens modules 33 are arranged in a one-to-one correspondence with multiple mounting brackets 32. Each lens module 33 is mounted on its corresponding mounting bracket 32, and the axis of each lens module 33 is parallel to the center line of the mounting bracket 32. It is ensured that the axis of the lens module 33 is consistent with the tilt direction of the mounting bracket 32, that is, the angle between the lens optical axis and the reference mounting plane of the mounting base 31 is equal to the angle between the support plane and the reference mounting plane on the mounting base 31.

[0062] For example, the mounting bracket 32 ​​can provide three different tilt angle specifications: 15°, 25°, and 35°. There are eight mounting brackets of each specification. Users can select eight mounting brackets of the same specification each time according to their shooting needs, such as using all 25° tilt angle mounting brackets 32 on the mounting base 31. When the lens module 33 is mounted on the mounting bracket 32, the angle between the axis of all lens modules 33 and the reference mounting plane of the mounting base 31 is 25°. This allows for adaptive selection of mounting brackets 32 with different tilt angles based on the usage scenario of the lens module 33 (i.e., suspended in a high-altitude or low-altitude environment).

[0063] It is understood that in the lens mounting assembly 30 provided in this embodiment of the present invention, multiple mounting brackets 32 are arranged in a circumferential array along the circumference of the mounting base 31. Each mounting bracket 32 ​​is detachably connected to the mounting base 31, and the supporting plane of each mounting bracket 32 ​​is set at an angle to the reference mounting plane of the mounting base 31. Multiple lens modules 33 are arranged one-to-one with the multiple mounting brackets 32. Each lens module 33 is detachably mounted to the corresponding mounting bracket 32, and the axis of each lens module 33 is parallel to the center line of the mounting bracket 32. By replacing the mounting brackets 32 with different tilt angles, the multi-angle shooting needs at different heights can be adapted: when the panoramic stitching camera is suspended in a high-altitude environment, a mounting bracket 32 ​​with a larger tilt angle can be selected to tilt the optical axis of the lens module 33 upward, expanding the coverage of the high-altitude image; when the panoramic stitching camera is suspended in a low-altitude environment, a mounting bracket 32 ​​with a smaller tilt angle can be selected to tilt the optical axis of the lens module 33 downward, avoiding the high-altitude image from obscuring low-altitude details.

[0064] Furthermore, the core challenge of panoramic stitching cameras lies in the stitching accuracy of multiple lens modules 33. This requires ensuring minimal matching of feature points in the overlapping areas of adjacent lens modules 33, and the key to stitching calibration is the consistency of the relative positions (including spacing, pitch angle, and yaw angle) of each lens module 33. Otherwise, problems such as mismatched feature points in overlapping areas, image ghosting, or local blurring can easily occur during the stitching process, severely affecting the integrity and timeliness of the panoramic image.

[0065] In this embodiment of the invention, the mounting base 31 provides a unified reference mounting plane for the lens modules 33. All lens modules 33 are fixed to this reference mounting plane by the mounting brackets 32, ensuring that the central axes of each lens module 33 are located on the same circumference, with the center of the circle being the center of the mounting base 31. This avoids positional deviations of the lens modules 33 due to uneven mounting surfaces. Furthermore, the circumferential array distribution of the mounting brackets 32 ensures consistency in the horizontal spacing and initial angle of each lens module 33. During production, all lens modules 33 can be mounted onto the mounting base 31 at once using the mounting brackets 32. By rotating the mounting base 31, the synchronous debugging of multiple lens modules 33 can be completed without the need for individual calibration of each lens module 33. This reduces the difficulty and cost of splicing calibration and improves product consistency and yield.

[0066] In other words, the angle between the support plane of the mounting bracket 32 ​​and the axis of the mounting base 31 is negatively correlated with the height of the shooting image, where the height of the shooting image is the vertical field of view coverage in the image.

[0067] The smaller the angle between the support plane of the mounting bracket 32 ​​and the axis of the mounting base 31, the better the camera can capture images from a high position. Conversely, the larger the angle between the support plane of the mounting bracket 32 ​​and the axis of the mounting base 31, the better the camera can capture images from a low position.

[0068] like Figure 2 As shown, when the angle between the supporting plane of the mounting bracket 32 ​​and the axis (vertical plane) of the mounting base 31 is 40°, the angle between the optical axis of the lens module 33 and the horizontal plane is also 40°. If the lens field of view is selected as 100°, the angle between the upper edge of the field of view and the horizontal plane is 10°, and the lower edge of the field of view is parallel to the vertical plane. Therefore, when the lens field of view remains unchanged, if the angle between the supporting plane of the mounting bracket 32 ​​and the vertical plane is greater than 40°, the field of view of the eight lens modules 33 in this embodiment will converge at the bottom. After image stitching, no blind spots can be achieved at the bottom of the product. In this case, the product is suitable for installation at a high place for overlooking. When the product is installed at a low place and a panoramic view is needed, the angle between the supporting plane of the mounting bracket 32 ​​and the axis of the mounting base 31 can be reduced, and the angle between the upper edge of the field of view and the horizontal plane can be increased, thereby capturing images from a high place.

[0069] Figure 3 This is a schematic diagram of the structure of the mounting body 321 in the lens mounting assembly 30 provided in this embodiment of the utility model.

[0070] See Figure 3 In some embodiments of this utility model, each mounting bracket 32 ​​includes a mounting body 321 and a supporting body 322. The mounting body 321 and the supporting body 322 can be mechanically connected, such as by bolts, riveting or integral injection molding.

[0071] The mounting body 321 is made of flat aluminum alloy and has 2 to 4 threaded holes for detachable connection with the mounting base 31 via countersunk screws.

[0072] The support body 322 is an inclined plate relative to the mounting base 31. The support body 322 is connected to the mounting body 321 and is set at an angle to the mounting body 321, with the angle ranging from 5° to 60°. The support body 322 has a mounting groove 322-1, the shape of which is adapted to the outer contour of the lens module 33. The lens module 33 is embedded in the mounting groove 322-1 and fixedly connected to the support body 322.

[0073] The included angle between the supporting body 322 and the mounting body 321 determines the tilt angle of the lens module 33 relative to the reference mounting plane: when the included angle between the supporting body 322 and the mounting body 321 is 15°, the optical axis of the lens module 33 tilts downward by 15° relative to the reference mounting plane of the mounting base 31.

[0074] Continue reading Figure 3 In some embodiments of this utility model, the support body 322 is further provided with a dispensing groove 322-2, which is located on opposite sides of the mounting groove 322-1, such as the upper and lower sides of the mounting groove 322-1. The lens module 33 is bonded and fixed to the support body 322 by UV adhesive in the dispensing groove 322-2. The UV adhesive cures rapidly under UV lamp irradiation, and the Shore hardness after curing can reach D70~D90. High hardness means that the adhesive layer is not easily deformed by vibration, temperature change or external impact during long-term use, ensuring that the relative position of the lens module 33 and the support body 322 remains stable over a long period of time.

[0075] Traditional screw fixing requires machining screw holes in the lens module 33 or mounting bracket 32 ​​and fixing through the tightening force of the metal screw. Because the lens module 33 (especially precision components containing CMOS sensors and lenses) has low rigidity, localized stress concentration easily occurs at the contact point when the screw is tightened. This can easily lead to minor deformations of the lens or sensor (such as bending or warping), which in turn changes the focal length or aberration characteristics of the optical system, directly resulting in out-of-focus or blurry images. In contrast, this embodiment uses adhesive for fixing. The viscoelastic properties of the adhesive disperse the fixing force to the contact interface between the lens module 33 and the support body 322, fully filling the tiny gaps between them. After curing, a continuous elastic adhesive layer is formed, evenly distributing the stress throughout the contact area.

[0076] Furthermore, traditional adhesive dispensing locations (such as the bottom or top of the lens module 33) are often obstructed by the bracket, preventing the UV lamp from fully irradiating the adhesive, resulting in incomplete curing and insufficient bonding strength. In this embodiment, however, the adhesive dispensing groove 322-2 is located on opposite sides of the mounting groove 322-1, adhering to the side wall of the lens module 33. Since the side wall of the lens module 33 is a vertical or inclined exposed surface, when the adhesive dispensing groove 322-2 is located on both sides, the UV lamp can directly irradiate the adhesive surface from a horizontal direction, avoiding shadowed curing areas caused by bracket obstruction.

[0077] The mounting groove 322-1 has a longer perimeter than the side walls on both sides. If the mounting groove 322-1 is rectangular, the dispensing groove 322-2 extends along the side wall, which can significantly increase the contact area between the adhesive and the lens module 33 and the support body 322. A larger contact area means higher adhesion and can withstand greater vibration and impact.

[0078] Continue reading Figure 3 In some embodiments of this utility model, one or two positioning holes 322-3 are provided on the support body 322. The positioning holes 322-3 are located on the groove wall of the mounting groove 322-1. The positioning holes 322-3 cooperate with the positioning pins on the lens module 33 to position the lens module 33, ensuring the angular accuracy of the lens module 33 during installation and avoiding misalignment of the image splicing due to installation deviation, such as the offset of the overlapping area of ​​adjacent lenses.

[0079] Continue reading Figure 3 In some embodiments of this utility model, a heat-conducting body 323 is provided on the side of the support body 322 away from the mounting body 321, and a heating film is provided on the heat-conducting body 323.

[0080] To address the issues of uneven temperature, lens distortion, and out-of-focus problems caused by the heat generated by the sensor board in the panoramic stitching camera lens module 33, a heat-conducting body 323 is installed on the side of the support body 322 away from the mounting body 321, and a heating film is installed on the heat-conducting body 323. This can effectively solve the imaging quality problems caused by the temperature difference between the front and back of the lens.

[0081] The lens module 33 of a panoramic stitching camera typically consists of components such as a sensor board (image sensor), lens barrel, and lens group. During operation, the sensor board generates Joule heat due to photoelectric conversion. If this heat cannot dissipate in time, the temperature near the sensor board will be significantly high, creating a noticeable temperature gradient. This results in varying degrees of distortion before and after the lens, causing the image to be out of focus.

[0082] The heating film provided in this embodiment is attached to the surface of the heat-conducting body 323 (such as aluminum alloy fins or graphite heat-conducting sheets). It transfers heat to the low-temperature area of ​​the lens module 33 by heating up when energized, compensating for the uneven heat caused by the heating of the sensor board. This effectively solves the problem of temperature difference between the front and back of the lens caused by the heating of the sensor board, suppresses the blurring and splicing misalignment caused by thermal deformation, and significantly improves the imaging quality and environmental adaptability of the panoramic splicing camera.

[0083] The heat-conducting body 323, serving as the intermediate heat transfer medium between the heating film and the lens module 33, needs to possess high thermal conductivity and a large-area contact characteristic. Its function is to convert the concentrated heat of the heating film into a uniformly distributed heat flow. The heat-conducting body 323 uses a high thermal conductivity material (such as aluminum alloy) and diffuses the point heat source of the heating film into a surface heat source, reducing the thermal resistance of the heat transfer path.

[0084] Continue reading Figure 3 In some embodiments of this utility model, a reinforcing member 324 is provided between the mounting body 321 and the supporting body 322. The reinforcing member 324 enhances the connection rigidity and resistance to deformation between the two.

[0085] Among them, the reinforcing member 324 can adopt a triangular structure support, such as forming a three-dimensional frame with the mounting body 321 and the supporting body 322, and using the anti-deformation characteristics of the geometric structure, such as the stability of the triangle, to suppress the bending of the connection interface.

[0086] Continue reading Figure 3 In some embodiments of this utility model, the support body 322 is provided with fixing holes 322-4, which are used to fix the lens module 33. For lens modules 33 that are relatively heavy, after being fixed with adhesive, fixing holes 322-4 can be used for auxiliary locking to improve the stability of the lens module 33.

[0087] Figure 4 This is an exploded view of the panoramic stitching camera provided in this embodiment of the utility model.

[0088] See Figure 4 This utility model provides a panoramic stitching camera, which includes a housing assembly 10, multiple window assemblies 20 and a lens mounting assembly 30.

[0089] The housing assembly 10 is made of cylindrical aluminum alloy. The housing assembly 10 has an internal cavity 11 for accommodating the lens mounting assembly 30, the control motherboard, and the power module. The housing assembly 10 has multiple viewing windows 12, each of which is connected to the cavity 11. The multiple viewing windows 12 are arranged in a circular array along the circumference of the housing assembly 10.

[0090] Multiple window components 20 are disposed one-to-one in each window 12, and each window component 20 is detachably connected to the housing component 10; and a lens mounting component 30 including the above embodiment is disposed in the receiving cavity 11, and the position of the lens module 33 corresponds to the position of the window component 20.

Figure 6 This is a cross-sectional view of the window component 20 in the panoramic stitching camera provided in this embodiment of the utility model. Figure 7 This is a partial structural schematic diagram of the window component 20 in the panoramic stitching camera provided in this embodiment of the utility model.

[0092] See Figures 5 to 7 In some embodiments of the present invention, each window assembly 20 includes a window unit 21, a window glass 22, and a window pressure plate 23.

[0093] The viewing unit 21 includes a viewing shell 211 and a sealing member 212. The viewing shell 211 is injection molded from PC (polycarbonate) engineering plastic and has an interconnected mounting portion 211-1 and a viewing body 211-2. The sealing member 212 is embedded in the sealing groove of the mounting portion 211-1 and is press-fitted with the edge of the viewing window 12 of the housing assembly 10. Multiple anti-detachment portions 212-1 are distributed circumferentially on the sealing member 212, and each anti-detachment portion 212-1 is arranged around the edge of the mounting portion 211-1 and holds the edge of the mounting portion 211-1 tightly.

The cover 14 is disposed on the housing body 13 and is detachably connected to the housing body 13. The cover 14 and the housing body 13 enclose an accommodating cavity 11. A plurality of viewing windows 12 are disposed on the housing body 13 and are arranged in a circular array along the circumference of the housing body 13.

[0099] like Figure 9As shown, when the panoramic stitching camera provided by this utility model is working, external light enters the receiving cavity 11 through the window glass 22 of the window assembly 20, and is focused onto the CMOS sensor by the lens group of the lens module 33. The sensor converts the light signal into an electrical signal and transmits it to the control motherboard, and finally transmits it to the monitoring terminal wirelessly or via wired connection. The images synchronously acquired by the multi-lens module 33 are stitched together by an algorithm to form a 360° panoramic view. It is ensured that the center of the window glass 22 coincides with the center of the window 12, and the center of the mounting groove 322-1 coincides with the center of the support body 322, ensuring that light enters perpendicularly from the window onto the lens optical axis, avoiding image distortion.

[0100] Through the circumferential window design of the housing assembly 10, the sealed and detachable structure of the window assembly 20, and the adjustable angle bracket of the lens mounting assembly 30, the panoramic camera achieves 360° imaging without blind spots, multi-scene adaptation, and convenient maintenance. It can be widely used in fields with high requirements for image quality and environmental adaptability, such as security monitoring and smart homes. By changing the mounting brackets 32 with different tilt angles, it can adapt to different scene requirements.
