[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0039] The core of this invention is to provide a panoramic monitoring device that, by stitching together the field of view of at least two telephoto camera components to form a larger monitoring range, can simultaneously meet the needs of wide-area monitoring and local monitoring.

[0040] The panoramic monitoring device provided by this utility model includes an imaging module 01, a rotating component 3, and an image processing element. Please refer to the following for details. Figure 2 .

[0041] The imaging module 01 specifically includes at least two telephoto camera components 1 arranged vertically. Specifically, the telephoto camera component 1 is relative to the short-focus camera component. The telephoto camera component 1 has a narrower field of view and can be used to focus on the monitored target for detailed viewing, while the short-focus camera component has a wider field of view and is used for large-area monitoring.

[0042] At least two telephoto camera components 1 are arranged vertically, and the fields of view of two adjacent telephoto camera components 1 overlap by an area S1. Specifically, the overlapping area S1 can be the overlapping area S1 of the vertical fields of view. The monitored target can be dynamic or static, without restriction.

[0043] If the overlapping area S1 is specifically the overlapping area of ​​the vertical field of view, then the field of view of the two telephoto camera components 1 corresponding to imaging module 01 along the vertical direction corresponds to the monitoring direction and range of the monitored target. At least two telephoto camera components 1 together form a monitoring area S2, which is used to monitor the monitored target. The monitoring angle of the monitoring area S2 does not exceed the sum of the field of view angles of at least two telephoto camera components 1. Here, the field of view angle corresponds to the vertical field of view angle. The specific number of telephoto camera components 1 and the value of the large angle of view that can be formed are determined according to the actual monitoring needs, and are not limited here. The phrase "not exceeding the sum of the field of view angles of at least two telephoto camera components 1" mentioned above specifically means less than or equal to the sum of the field of view angles of at least two telephoto camera components 1. Since at least two telephoto camera components 1 can form a large field of view angle by superimposing the field of view, it can meet the needs of wide-area monitoring. The specific monitoring angle of the monitoring area S2 is related to the size of the overlapping area S1, and can be set according to the actual usage needs.

[0044] By setting up at least two telephoto camera components 1, the monitoring angle of the entire imaging module 01 can be effectively expanded, thereby increasing the monitored range and forming a larger field of view to meet the needs of wide-area monitoring. The ability of the telephoto camera components 1 to focus on specific areas meets the needs of local monitoring. Integrating at least two telephoto camera components 1 onto the same monitoring device results in high integration and ease of use, avoiding the loss of monitored targets due to latency during tracking.

[0045] The rotating component 3 can drive the imaging module 01 to rotate to acquire image information, thereby enabling at least two telephoto camera components 1 to rotate 360° in the circumference, so as to acquire single-frame images from different angles and meet the needs of panoramic monitoring.

[0046] The image processing element is connected to the telephoto camera assembly 1 and processes information based on the overlapping region S1 and image information acquired by at least two telephoto camera assemblies 1 to obtain a panoramic image with a wide field of view. Specifically, the image stabilization control element outputs a synchronization signal to control the output of image information by the telephoto camera assembly 1, and the image processing element acquires and processes the image information. The number of times the synchronization signal is output is related to the number of single-frame images corresponding to the panoramic image. For example, if N single-frame images are stitched together to form a panoramic image, then the number of times the image stabilization control element outputs the synchronization signal is N. Specific image processing includes generating image cropping information based on the overlapping region and cropping the acquired multi-frame images during stitching to form the desired panoramic image. Specific image processing may also include image compression, which can compress and output the acquired multi-frame images. The image processing element can output the processed image wirelessly or via a wired connection. Wired output can be achieved by connecting a signal cable via a connector, while wireless output can be achieved using a Bluetooth module.

[0047] In this embodiment, by setting the field of view of at least two telephoto camera components 1 to have an overlapping area S1, it can be ensured that the field of view angles corresponding to at least two telephoto camera components 1 can be superimposed to form a longer detection distance and a larger field of view angle.

[0048] Specifically, the measure to make the fields of view of the two telephoto camera components 1 overlap by an area S1 can be achieved by setting the setting angle of the telephoto camera components 1, specifically the angle between the edge of the field of view of the telephoto camera components 1 and the horizontal plane.

[0049] In one specific embodiment, along the vertical direction, the setting angle of two adjacent telephoto camera components 1 gradually increases, such as... Figure 2 , Figure 3 The meaning is shown. With Figure 3 Taking the example of three telephoto camera components 1 in the illustrated configuration, the telephoto camera component 1 at the highest vertical position has the largest setting angle, the telephoto camera component 1 at the middle position has a slightly smaller setting angle, and the telephoto camera component 1 at the lowest vertical position has the smallest setting angle. The field of view of all three telephoto camera components 1 is set upwards to meet the requirement that the field of view of two adjacent telephoto camera components 1 overlaps by a region S1, so that the field of view angles of at least two telephoto camera components 1 can be superimposed to form a larger field of view.

[0050] In another specific embodiment, along the vertical direction, among at least two telephoto camera components 1, the telephoto camera component 1 located at the highest vertical position has the smallest setting angle, and the telephoto camera component 1 located at the lowest vertical position has the largest setting angle. Figure 3The illustrated setup includes three telephoto camera components 1. Specifically, the positions of the telephoto camera component 1 at the highest vertical position and the telephoto camera component 1 at the lowest vertical position are swapped, so that the field of view of the telephoto camera component 1 at the highest vertical position is downward and the field of view of the telephoto camera component 1 at the lowest vertical position is upward. This is to meet the requirement that the field of view of two adjacent telephoto camera components 1 overlaps by a region S1, so that the field of view angles of at least two telephoto camera components 1 can be superimposed to form a larger field of view.

[0051] In this embodiment, it should be noted that the size of the overlapping area S1 needs to be determined based on the range of the actual monitoring area S2 and the location of the monitoring target. Specifically, under the premise of setting the overlapping area S1, the monitoring target should be avoided from being in the blind spot, so as to ensure reliable monitoring of the monitoring target.

[0052] like Figure 3 As shown, the relatively close edges of the field of view of two adjacent telephoto camera components 1 intersect at point A. One side of point A corresponds to the overlapping area S1, and the other side corresponds to the area far from the overlapping area S1. The other side corresponds to the blind zone. It is necessary to avoid the monitored target being located in the blind zone. Specifically, the distance between point A and the intersection point B of the field of view of at least two telephoto camera components 1 (at a certain distance, the field of view of at least two telephoto camera components 1 can be regarded as intersecting at point B) can be limited. The distance is set within a reasonable range to ensure reliable monitoring of the monitored target and avoid an excessively large overlapping area S1.

[0053] Based on the above embodiments, please refer to Figure 2 The rotating component 3 is specifically located on the lower side of the imaging module 01, and the lower side here is... Figure 2 In terms of the vertical orientation, the angle between the vertical viewing angle centerline of the telephoto camera assembly 1 and the horizontal plane increases along the direction away from the rotating component 3. With this arrangement, at least two telephoto camera assemblies 1 can form an upward viewing angle range, which can be used for searching and monitoring targets at low altitudes. It can make full use of the height space to install at least two telephoto camera assemblies 1 in sequence, resulting in a relatively compact structure and reducing the space occupied by the entire monitoring equipment.

[0054] Taking one specific implementation method as an example, such as Figure 3 As shown, from top to bottom, they are the first group of telephoto camera components 1, the second group of telephoto camera components 1, and the third group of telephoto camera components 1. Figure 3The field of view of the first telephoto camera assembly 1 is the angle formed by the two solid lines, and the midline of the angle corresponds to the first vertical viewing angle centerline of the first telephoto camera assembly 1; the field of view of the second telephoto camera assembly 1 is the angle formed by the two dashed lines, and the midline of the angle corresponds to the second vertical viewing angle centerline of the second telephoto camera assembly 1; the field of view of the third telephoto camera assembly 1 is the angle formed by the two dotted lines, and the midline of the angle corresponds to the third vertical viewing angle centerline of the third telephoto camera assembly 1.

[0055] For example, if the angle between the center line of the first vertical viewing angle and the horizontal plane is 30 degrees, the angle between the center line of the second vertical viewing angle and the horizontal plane is 15 degrees, and the angle between the center line of the third vertical viewing angle and the horizontal plane is 0 degrees, then the large field of view that the three sets of telephoto camera components 1 can form is 45 degrees. This corresponds to the case where at least two telephoto camera components 1 have the same field of view.

[0056] If the angle between the center line of the first vertical viewing angle and the horizontal plane is 20 degrees, the angle between the center line of the second vertical viewing angle and the horizontal plane is 10 degrees, and the angle between the center line of the third vertical viewing angle and the horizontal plane is 0 degrees, then the large field of view that the three sets of telephoto camera components 1 can form is 30 degrees. This corresponds to the case where at least two telephoto camera components 1 have the same field of view.

[0057] If the angle between the center line of the first vertical viewing angle and the horizontal plane is 30 degrees, the angle between the center line of the second vertical viewing angle and the horizontal plane is 10 degrees, and the angle between the center line of the third vertical viewing angle and the horizontal plane is 0 degrees, then the large field of view that the three sets of telephoto camera components 1 can form is 40 degrees. At least two of the telephoto camera components 1 may have different field of view angles.

[0058] Based on any of the above embodiments, please refer to Figure 3 The angle formed by the vertical viewing angle center lines of two adjacent telephoto camera components 1 is equal to the field of view angle of the telephoto camera component 1.

[0059] In this case, such as Figure 3 As shown, from top to bottom, they are the first group of telephoto camera components 1, the second group of telephoto camera components 1, and the third group of telephoto camera components 1. The angle formed by the vertical viewing angle center lines of two adjacent telephoto camera components 1 is equal to the field of view angle of the telephoto camera component 1. That is, the field of view angles of the three groups of telephoto camera components 1 are equal. The monitoring angle of the corresponding monitoring area S2 is a multiple of the field of view angle of the telephoto camera component 1. Here, the multiple is the number of telephoto camera components 1 set.

[0060] In this embodiment, at least two telephoto camera components 1 are of the same model, meaning their field of view is identical in the horizontal, vertical, and diagonal directions. By directly integrating at least two telephoto camera components 1 onto the same monitoring device, and by stitching together the fields of view of at least two telephoto camera components 1 to form a long-distance, wide-area, and precise monitoring system, it is possible to achieve focused monitoring of the target while maintaining a wide viewing angle. The structure is relatively simple, reducing design and manufacturing costs.

[0061] Based on any of the above embodiments, please refer to Figure 2 The imaging module 01 also includes at least two image stabilization components 2, and each telephoto camera component 1 is provided with an image stabilization component 2 in the optical path direction.

[0062] Each telephoto camera assembly 1 is equipped with an image stabilization component 2 in the optical path direction. Specifically, the image stabilization component 2 is able to reflect the light from the monitored target to the corresponding position of the telephoto camera assembly 1, so that the telephoto camera assembly 1 can receive the reflected light and form an image.

[0063] At least two image stabilization components 2 correspond to at least two telephoto camera components 1. The at least two telephoto camera components 1 can compensate for the optical axis offset caused by the rotation of the rotating component 3 through the synchronous swing of the corresponding at least two image stabilization components 202, so as to ensure the stability of the field of view of the telephoto camera components 1, avoid the imaging blur caused by the optical axis offset, and ensure the imaging quality of a single frame image, that is, ensure the imaging quality of the panoramic image.

[0064] Based on any of the above embodiments, please refer to Figure 2 , Figure 3 The image stabilization component 2 can rotate relative to its corresponding telephoto camera component 1. The rotation axis of the image stabilization component 2 is parallel to the rotation axis of the rotating component 3. The rotation of the image stabilization component 2 is used to adjust and align the vertical detection area edges of its corresponding telephoto camera component 1 and the telephoto camera component 1 adjacent to the corresponding telephoto camera component 1.

[0065] The image stabilization component 2 and the telephoto camera component 1 are in a one-to-one correspondence. Each image stabilization component 2 is used to reflect the light of the corresponding monitoring target to the position of the telephoto camera component 1 so as to form an image.

[0066] The rotation of the image stabilization component 2 relative to its corresponding telephoto camera component 1 allows for the alignment of the vertical detection edges of the corresponding telephoto camera component 1 and its adjacent telephoto camera components 1, even when misalignment is determined based on image information captured by two adjacent sets of telephoto camera components 1. This ensures alignment of the field-of-view centers of two adjacent telephoto camera components 1. Since each image stabilization component 2 can be rotated and adjusted, alignment of the field-of-view centers of at least two telephoto camera components 1 is guaranteed, ensuring the imaging quality of the imaging module 01.

[0067] Based on any of the above embodiments, please refer to Figure 2 The image stabilization component 2 includes an image stabilizer 202, the swing axis of which is parallel to the rotation axis of the rotation component 3.

[0068] The swing axis of the image stabilizer 202 in each image stabilization component 2 is set parallel to the rotation axis of the rotation component 3, so that the swing speed of the image stabilizer 202 and the rotation speed of the rotation component 3 are consistent, avoiding the generation of rotation speed difference, ensuring the reliable use effect of the image stabilizer 202, and ensuring the quality of the single frame image output by the telephoto camera component 1.

[0069] Specifically, the parallel alignment of the swing axis of the image stabilizer 202 and the rotation axis of the rotating component 3 can be achieved by improving the support structure on which the image stabilizer 202 is mounted. For example, the swing axis or swing axis hole on the support structure can be machined so that its axis is parallel to the rotation axis of the rotating component 3. After machining or after the monitoring equipment has been used for a period of time, the swing axis or swing axis hole can be calibrated to ensure the imaging quality of the monitoring equipment.

[0070] Based on any of the above embodiments, please refer to Figure 2 , Figure 4 It also includes a bracket assembly 4 connected to the rotating assembly 3. The bracket assembly 4 has at least two first support portions 401 in the height direction for connecting the telephoto camera assembly 1. The plane of the first support portion 401 is parallel to the vertical viewing angle center line of its corresponding telephoto camera assembly 1.

[0071] The bracket assembly 4 is connected to the rotating assembly 3, enabling the imaging module 01 to be driven by the rotating assembly 3, allowing the imaging module 01 to rotate circumferentially to achieve a panoramic image capture effect and ensure the effectiveness of panoramic monitoring. Specifically, the bracket assembly 4 can be detachably connected to the rotating assembly 3, which can be achieved using fastening pins, fastening screws, fastening bolts, nuts, etc., without further restrictions.

[0072] The height direction of the bracket assembly 4 is also the vertical direction. At least two first support parts 401 are provided along the height direction of the bracket assembly 4, which are used to respectively connect at least two telephoto camera assemblies 1. The specific form of the first support part 401 is not limited. It is designed according to the specific form of the telephoto camera assembly 1 to ensure a reliable installation effect of the telephoto camera assembly 1 relative to the first support part 401.

[0073] The plane of the first support part 401 is set parallel to the vertical viewing angle center line of the corresponding telephoto camera component 1. Specifically, the two opposite edges C of the first support part 401 are both set parallel to the vertical viewing angle center line, so that the plane of the first support part 401 used to install the telephoto camera component 1 has a preset angle. After the telephoto camera component 1 is installed on the corresponding first support part 401, the field of view of adjacent telephoto camera components 1 can have an overlapping area S1. A larger field of view can be formed by piecing together at least two telephoto camera components 1 to meet the needs of wide-area monitoring.

[0074] Based on any of the above embodiments, please refer to Figure 4 The bracket assembly 4 includes a main body 403, a first support 401 connected to the side of the main body 403, and a telephoto camera assembly 1 connected to the side of the first support 401 away from the main body 403.

[0075] like Figure 4 As shown, by placing the first support portion 401 on the side of the main body 403, the height space of the main body 403 can be utilized to install the first support portion 401. This allows the installation of the telephoto camera assembly 1 to fully utilize the height space formed by the bracket assembly 4, reducing the overall size and space occupied by the monitoring equipment, and making the structure more compact. Taking the main body 403 as a flat plate structure as an example, the "side" here specifically refers to the circumferential part of the flat plate structure, as opposed to the top and bottom of the flat plate structure.

[0076] Based on the arrangement of the first support portion 401 on the side of the main body portion 403, in order to ensure reliable installation of the telephoto camera assembly 1 relative to the first support portion 401.

[0077] In one specific implementation, a reinforcing member may also be provided on the main body 403. The specific shape and size of the reinforcing member can be determined in combination with the actual simulation situation, such as by using stress analysis software and theoretical analysis design.

[0078] Based on any of the above embodiments, please refer to Figure 2 , Figure 4 At least two second support portions 402 for connecting the image stabilizing component 2 are provided in the height direction of the support assembly 4. The mounting plane of the second support portion 402 is set towards the telephoto camera assembly 1 and parallel to the rotation axis of the rotating assembly 3.

[0079] The arrangement of at least two second support portions 402 corresponds to the support and installation of at least two image stabilizing components 2. Specifically, the second support portion 402 may be located on the top of the main body portion 403, where the top is... Figure 2 and Figure 4 In terms of the upper and lower positions, the upper side plane of the main body 403 corresponds to the top position.

[0080] The position of the second support part 402 on the same main body 403 relative to the first support part 401 can satisfy the requirement of reliably installing the corresponding image stabilization component 2 and telephoto camera component 1, and ensuring the overall reliability and stability after installation. It is also required that the optical path of the telephoto camera component 1 can pass through the image stabilization component 2, and that the telephoto camera component 1 and the image stabilization component 2 do not interfere with each other.

[0081] The mounting plane of the second support part 402 is the plane used to mount the image stabilization component 2. It can be set towards the telephoto camera component 1 and perpendicular to the rotation axis of the rotating component 3, so that the image stabilization component 2 can be reliably supported by the second support part 402, and it is convenient to set the swing axis of the image stabilization component 2 and the rotation axis of the rotating component 3 to be parallel.

[0082] Based on any of the above embodiments, please refer to Figure 2 The second support part 402 is connected to one side of the main body part 403 in the height direction and is set close to the first support part 401, so that the mounting plane of the second support part 402 is set towards the telephoto camera assembly 1, so that each image stabilization assembly 2 can maintain the field of view of its corresponding telephoto camera assembly 1 during the monitoring process and ensure the imaging quality.

[0083] A clearance area is provided between the second support part 402 and the first support part 401. The clearance area provides space for the swinging and installation of the image stabilization assembly 2. Specifically, the clearance area allows the image stabilization assembly 2 to swing without interfering with the normal operation of the telephoto camera assembly 1. The specific size and shape of the clearance area are not limited and can be determined according to actual needs.

[0084] Taking a specific implementation as an example, the clearance area is an arc-shaped structure, and the two ends of the arc-shaped structure correspond to the limits of the maximum bidirectional swing of the image stabilization component 2; or, the clearance area is a straight structure, and the distance between the straight structure and the second bearing part 402 is the limit of the maximum bidirectional swing of the image stabilization component 2. Here, "bidirectional" refers to the two directions of rotation along the swing axis: clockwise and counterclockwise.

[0085] In this embodiment, the provision of the clearance area also provides space for the installation of the image stabilization component 2. Specifically, the image stabilization component 2 has a portion located within the clearance area, specifically, the swingable image stabilization element 202 is located within the clearance area so that it can swing flexibly to ensure the imaging quality of a single frame image.

[0086] Based on any of the above embodiments, please refer to Figure 2 , Figure 5 , Figure 6 , Figure 8 The telephoto camera assembly 1 includes a first mounting bracket 101 and a camera assembly 102. The first mounting bracket 101 is provided with a first mounting position 1011 and a second mounting position 1012. The first mounting position 1011 is used to connect the first mounting bracket 101 and the camera assembly 102, and the second mounting position 1012 is used to connect the first mounting bracket 101 and the first support part 401.

[0087] The first mounting position 1011 and the second mounting position 1012 can be holes. The second mounting position 1012 of the first mounting bracket 101 is connected to the first support part 401, thus completing the installation of the first mounting bracket 101 relative to the bracket assembly 4. The first mounting position 1011 of the first mounting bracket 101 is used to connect the camera assembly 102 and the first mounting bracket 101, that is, the camera assembly 102 and the first mounting bracket 101 can be connected as a whole.

[0088] When adjusting the pitch angle of the camera assembly 102, first release the lock between the first mounting bracket 101 and the first support portion 401, allowing the first mounting bracket 101 and the camera assembly 102 to rotate relative to the first support portion 401. Specifically, releasing the lock involves loosening the fastening bolts between the second mounting position 1012 of the first mounting bracket 101 and the first support portion 401, allowing the first mounting bracket 101 and the camera assembly 102 to rotate relative to the first support portion 401, thus adjusting the pitch angle of the telephoto camera assembly 1.

[0089] Specifically, either the first support portion 401 or the second mounting position 1012 is an adjustable mounting position, enabling mechanical adjustment of the tilt angle of the telephoto camera assembly 1. Specifically, if the first support portion 401 is an adjustable mounting position, it can be provided with an elongated or oblong hole, corresponding to a circular hole in the second mounting position 1012; conversely, if the second mounting position 1012 is an adjustable mounting position, it can be an elongated or oblong hole, while the first support portion 401 can be a circular hole. Based on the adjustable mounting position, after the tilt angle of the first mounting bracket 101 and the camera assembly 102 relative to the first support portion 401 is adjusted, the telephoto camera assembly 1 can still be reliably fixed to the first support portion 401 by fasteners passing through the corresponding holes in the second mounting position 1012 and the first support portion 401.

[0090] The motivation for adjusting the specific pitch angle is based on the size of the overlapping area S1 and the panoramic image information processed by the image processing element. If the overlapping area S1 between the fields of view of two adjacent telephoto camera components 1 is too large, the telephoto camera component 1 in the upper position will be adjusted upward by a certain angle, or the telephoto camera component 1 in the lower position will be adjusted downward by a certain angle. Which side of the telephoto camera component 1 needs to be adjusted depends on the actual situation and is not restricted. If the panoramic image obtained by the image processing element has tortuosity, it indicates that no panoramic image has been acquired. At least one telephoto camera component 1 needs to have its pitch angle adjusted to ensure that there is an overlapping area S1 between two adjacent telephoto camera components 1, and that the size of the overlapping area S1 is sufficient to ensure that the monitored targets within the monitoring area S2 are effectively and reliably monitored.

[0091] In this embodiment, the specific positional distribution of the first mounting position 1011 and the second mounting position 1012 is not limited. For example, the first mounting position 1011 may be located in a relatively inner ring position, and the second mounting position 1012 may be located in a relatively outer ring position, so as to facilitate the rotational adjustment of the first mounting bracket 101 relative to the first support portion 401. Here, the inner and outer rings are defined by their distance from the center of the first mounting bracket 101, and the distance between the inner ring position and the center of the first mounting bracket 101 is relatively small.

[0092] In this embodiment, by setting either the first support part 401 or the second mounting position 1012 to an adjustable mounting position, it is possible to facilitate the mechanical adjustment of the pitch angle of the telephoto camera assembly 1 and ensure the quality of the panoramic image.

[0093] In this embodiment, the rotation of the telephoto camera assembly 1 relative to the first support portion 401 can be achieved using a common rotating shaft. Specifically, after the second mounting position 1012 of the first mounting bracket 101 of the telephoto camera assembly 1 is released from locking to the first support portion 401, it can rotate around the rotating shaft. After rotation, the second mounting position 1012 and the first support portion 401 can be reliably connected. In this case, it is suitable for adjusting the pitch angle at the ground end, and the real-time adjustment result can be displayed using a display device at the ground end.

[0094] In this embodiment, the rotation of the telephoto camera assembly 1 relative to the first support portion 401 can also be achieved by means of a straight pivot. Specifically, after the second mounting position 1012 of the first mounting bracket 101 of the telephoto camera assembly 1 is released from locking with the first support portion 401, the straight pivot allows the telephoto camera assembly 1 to rotate a certain angle relative to the first support portion 401 and then lock itself in a certain position. This is applicable to adjusting the overlap range of two adjacent telephoto camera assemblies 1 when the monitoring equipment is in operation, such as under low-altitude conditions, and the real-time adjustment results can be displayed on the ground-based display device, thus having better applicability.

[0095] Based on any of the above embodiments, please refer to Figure 4 , Figure 5 The first mounting bracket 101 has a third mounting position 1013. The third mounting position 1013 and the first support part 401 are rotatably connected by a first pin 1014. The axis of the first pin 1014 is perpendicular to the rotation axis of the rotating assembly 3. The axis of the first pin 1014 is... Figure 6 The diagram shows L1.

[0096] The first pin 1014 serves as the pivot for tilt adjustment of the telephoto camera assembly 1. The third mounting position 1013 is specifically a rotating hole. The first pin 1014 passes through the rotating hole and can be rotatably connected to the corresponding hole on the first support part 401, allowing the telephoto camera assembly 1 to rotate counterclockwise or clockwise relative to the first support part 401 around the axis of the first pin 1014 for tilt angle adjustment. After the adjustment is completed, a reliable connection is made between the second mounting position 1012 of the first mounting bracket 101 and the corresponding hole on the first support part 401, thus reliably fixing the telephoto camera assembly 1, after tilt angle adjustment, onto the first support part 401, ensuring the reliability of the telephoto camera assembly 1 in use.

[0097] The axis of the first pin 1014 is set perpendicular to the rotation axis of the rotating assembly 3. The actual adjustment made by rotating the telephoto camera assembly 1 around the first pin 1014 is as follows: Figure 3 The size of the overlapping region S1 shown.

[0098] Based on any of the above embodiments, please refer to Figure 2 , Figure 4 , Figure 7 The image stabilization assembly 2 includes a second mounting bracket 201, which has a fourth mounting position 2011. Either the fourth mounting position 2011 or the second support portion 402 is an adjustable mounting position, which is used to adjust the alignment of the vertical detection area edges of two adjacent sets of telephoto camera assemblies 1 by adjusting the mounting angle of the image stabilization assembly 202.

[0099] Either the fourth mounting position 2011 or the second support portion 402 is an adjustable mounting position. This adjustable mounting position provides conditions for mechanical adjustment of the mounting angle of the image stabilizer 202. Specifically, if the second support portion 402 is an adjustable mounting position, it can be a long or narrow hole, and the fourth mounting position 2011 is a round hole. Then, when adjusting the mounting angle of the image stabilizer 202, the fastening bolts between the fourth mounting position 2011 and the second support portion 402 can be loosened, allowing the image stabilizer 202 and the second mounting bracket 201 to rotate relative to the second support portion 402 for mechanical angle adjustment. After adjustment, the fastening bolts can be tightened.

[0100] Alternatively, the fourth mounting position 2011 can be an adjustable mounting position, specifically a long or narrow hole, and the second bearing part 402 can be a round hole. In this case, when adjusting the mounting angle of the image stabilizer 202, the fastening bolts between the fourth mounting position 2011 and the second bearing part 402 can be loosened, allowing the image stabilizer 202 and the second mounting bracket 201 to rotate relative to the second bearing part 402 for mechanical angle adjustment. After the adjustment is completed, the fastening bolts can be tightened.

[0101] In this embodiment, the rotation of the image stabilization component 2 relative to the first support portion 401 can be achieved using either a common rotating shaft or a single-axis rotating shaft. If the rotation can be adjusted directly on the ground using a simpler rotating shaft, and then the second mounting bracket 201 and the second support portion 402 are tightened with bolts, the angle of the image stabilization component 2 can be maintained in the adjusted position. The ability to control the rotation of the single-axis rotating shaft during operation and its self-locking feature makes it suitable for adjusting the installation angle of the image stabilization component 2 while the monitoring equipment is in operation.

[0102] The specific motivation for mechanically adjusting the angle of the image stabilization component 2 is based on the imaging quality of the panoramic image obtained by the image processing element. If the edges of the vertical detection areas of the images captured by the two adjacent sets of telephoto camera components 1 are misaligned, resulting in a misaligned panoramic image, then the angle of the image stabilization component 2 needs to be mechanically adjusted so that the image stabilization component 202 rotates relative to the telephoto camera component 102. This ensures that the edges of the vertical detection areas of the two adjacent sets of telephoto camera components 1 are aligned, and that the centers of the fields of view of the two adjacent sets of telephoto camera components 1 are aligned, which in turn ensures that the centers of the fields of view of the two adjacent sets of camera components 102 are aligned, thus ensuring the quality of the panoramic image.

[0103] It should be noted that either of the two image stabilizing components 202 in the two adjacent sets of camera components 102 can be rotated or both can be rotated and adjusted. The specific adjustment can be made adaptively according to the misalignment and deviation of the panoramic image information to ensure the imaging quality of the panoramic image.

[0104] Based on any of the above embodiments, please refer to Figure 7 , Figure 8 The second mounting bracket 201 has a fifth mounting position 2012. The fifth mounting position 2012 and the second bearing part 402 are rotatably connected by a second pin 2013. The axis of the second pin 2013 is parallel to the rotation axis of the rotating assembly 3. The axis of the second pin 2013 is... Figure 8 The meaning is shown in L2.

[0105] The second pin 2013 passes through the fifth mounting position 2012 and the second support part 402, meaning that the rotating holes on the fifth mounting position 2012 and the second support part 402 are correspondingly arranged. The second pin 2013 allows the second mounting bracket 201 and the image stabilizer 202 to rotate clockwise or counterclockwise relative to the first support part 401 around the axis of the second pin 2013, thus allowing for adjustment of the mounting angle. After adjustment, the fastening bolts between the fourth mounting position 2011 and the second support part 402 are tightened to maintain the adjusted mounting angle of the image stabilizer 202.

[0106] In this embodiment, it should be noted that the axis of the second pin 2013 is parallel to the rotation axis of the rotating component 3, and the axis of the second pin 2013 and the swing axis of the image stabilizer 202 are also parallel. However, the axis of the second pin 2013 and the axis of the swing axis of the image stabilizer 202 are two parallel lines. The swing of the image stabilizer 202 around the swing axis can compensate for the optical axis offset caused by the rotation during the process of the telephoto camera component 1 rotating to acquire image information, thus ensuring the stability of the field of view of the telephoto camera component 1. The rotation of the image stabilizer 202 around the second pin 2013 is to ensure that the edges of the vertical detection areas of at least two telephoto camera components 1 are aligned, thus ensuring the imaging quality.

[0107] Based on the above, the pitch angle of the telephoto camera assembly 1 is adjusted by the first pin 1014, the mounting angle of the image stabilization assembly 2 is adjusted by the second pin 2013, and the optical axis offset is compensated by the swing of the image stabilization component 202 around the swing axis, so as to ensure the quality of the panoramic images captured by at least two telephoto camera assemblies 1 through a combination of mechanical and software adjustments.
