[0002] In the field of panoramic monitoring equipment technology, multiple cameras are stitched together to form a larger panoramic monitoring range, ensuring reliable monitoring of the target.

[0003] Specifically, it is necessary to design the cabin structure so that light from the monitored target reaches the window position corresponding to the camera location, thereby enabling reliable imaging. How to design the cabin structure to ensure the imaging quality of panoramic monitoring equipment has always been a hot research topic for relevant technical personnel.

[0004] In summary, how to provide a cabin structure that can guarantee the imaging quality of panoramic monitoring equipment is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a cabin structure in which each image stabilization component only accepts light entering through the window component within its field of view, thereby ensuring image quality. Another purpose of this utility model is to provide a panoramic monitoring device including the above-described cabin structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cabin structure, comprising:

[0008] The cabin has several openings;

[0009] A plurality of window components are hermetically connected to a plurality of the openings, the window components being used to allow light from the monitored target to enter the cabin;

[0010] An imaging module is disposed within the cabin. The imaging module includes multiple image stabilization components and multiple camera components that correspond one-to-one with the image stabilization components. Each image stabilization component is used to receive light entering from the corresponding window component position within its corresponding incident field of view and is able to reflect the light to the corresponding camera component position.

[0011] Preferably, the window assembly has at least two components, and the vertical angle formed between the plane of each window assembly and the field of view center line L1 of the incident field of view of the corresponding single image stabilizing component is α, and the field of view angle of the single camera assembly is β, where α = 90° - 2 / β.

[0012] Preferably, the window assembly includes a window lens and a retaining ring located circumferentially to the window lens, the retaining ring being used to seal the window lens to the opening position.

[0013] Preferably, the pressure ring has a plurality of drainage outlets at at least one edge position.

[0014] Preferably, the drain outlet has a guide surface for draining liquid from the window lens.

[0015] Preferably, the guide surface is an inclined plane, and the inclined plane is arranged parallel to the plane of the window lens.

[0016] Preferably, it also includes a sunshade, which is connected to the top of the cabin to prevent radiated light from entering the cabin.

[0017] Preferably, the sunshade and the cabin are detachably connected.

[0018] Preferably, the edge of the sunshade is positioned to avoid the light entering range of several of the window components.

[0019] This utility model also provides a panoramic monitoring device, including the cabin structure described in any of the above claims.

[0020] The cabin structure provided by this utility model ensures the cabin, several window components, and imaging module. The cabin has several openings, and these openings and window components are sealed together to ensure the cabin's sealing effect and thus the imaging quality. The window components allow light from the monitored target to enter the cabin. Among the multiple image stabilization components included in the imaging module, each image stabilization component is only used to receive light entering from its incident field of view corresponding to the position of the window component. Light from other image stabilization components within their incident field of view will not enter. Each image stabilization component corresponds to a camera component, and the light is reflected to the corresponding camera component position for imaging. This avoids the overlap of light received by multiple image stabilization components and ensures the imaging quality.

[0021] The beneficial effects of this application are as follows: by sealing the window assembly and the opening, the sealing effect of the cabin is guaranteed; by allowing each stabilizing assembly to accept only the light entering through the window assembly within its incident field of view, reliable imaging of the monitored target is guaranteed, thus ensuring imaging quality.

[0031] 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.

[0032] The core of this invention is to provide a cabin structure that ensures reliable imaging of the monitored target and guarantees image quality. Another core aspect of this invention is to provide a panoramic monitoring device that includes the aforementioned cabin structure.

[0033] The cabin structure provided by this utility model includes a cabin 1, an imaging module 01 disposed within the cabin 1, and several window components 2. Please refer to the following for details. Figure 1 , Figure 6 .

[0034] The cabin 1 has several openings 11. The number of openings can be one, two or more. The specific shape and size of the openings can be set according to the actual situation without too many restrictions.

[0035] Several openings 11 are sealed and connected to several window components 2. The window components 2 are specifically used for the light of the monitored target to pass through and enter the cabin 1 so as to enable imaging.

[0036] In one specific implementation, the window component 2 is provided, and the opening 11 provided on the corresponding cabin 1 is also provided only once.

[0037] In one specific implementation, two window components 2 are provided, and two openings 11 are also provided on the corresponding cabin 1.

[0038] The airtight connection between window assembly 2 and opening 11 can be achieved by using sealing rings, gaskets, sealant, etc., which can ensure the reliable sealing effect of cabin 1 and thus improve imaging quality.

[0039] An imaging module is located inside the cabin 1. The imaging module includes multiple image stabilization components 5 and multiple camera components 6 that correspond one-to-one with the image stabilization components 5. Each image stabilization component 5 is used to receive light entering through the window component 2 within its incident field of view and can reflect the light to the position of the corresponding camera component 6.

[0040] It should be noted that the incident field of view corresponding to the image stabilization component 5 actually corresponds to the field of view angle of the camera component 6. After the light enters the image stabilization component 5 from the incident field of view, it is reflected and reflected through the reflection optical path to the corresponding position of the camera component 6. The image sensor of the camera component 6 then forms an image, thereby realizing the acquisition of the monitoring target within the monitoring area of ​​the imaging module. Figure 6 The corresponding incident field of view of the first set of image stabilization components 5 is the range formed by the two straight lines that form the β angle.

[0041] Each stabilizing component 5 only collects light rays entering through the window component 2 within its incident field of view; light rays within the incident field of view of other stabilizing components 5 are not collected. If the monitored target is divided into a first part and a second part, the light rays of the first part can only enter the incident field of view of one stabilizing component 5, and the light rays of the second part can only enter the incident field of view of another stabilizing component 5. This avoids discrepancies between the final image and the actual monitored target image, ensuring image quality.

[0042] Specifically, the light from the monitored target can enter the cabin 1 through a single window assembly 2 and be reflected by the image stabilization assembly 5 to the camera assembly 6 corresponding to the position of the image stabilization assembly 5, thus enabling imaging; alternatively, the light from the monitored target can enter the cabin 1 through two window assemblies 2, with the light at the corresponding position of each window assembly 2 being reflected by the image stabilization assembly 5 to the camera assembly 6 corresponding to each image stabilization assembly 5, thus enabling imaging. It should be noted that any camera assembly 6 only receives the light reflected from the image stabilization assembly 5 at its corresponding window position; reflected light from other window positions is not received. One image stabilization assembly 5 corresponds to one camera assembly 6.

[0043] Taking one specific implementation method as an example, such as Figure 2 As shown, the cabin 1 has three vertical openings 11, corresponding to three sets of camera components 6, three sets of image stabilization components 5, and three sets of window components 2. Light from the monitored target is reflected by the three sets of window components 2 and the corresponding image stabilization components 5, and then enters the position of the camera component 6 corresponding to that image stabilization component 5 to form an image. The image information acquired by the three sets of camera components 6 can be stitched together by an image processing element to form a wide-angle panoramic monitoring image and output it for the operator to observe. The wide-angle refers to the superposition of the field of view angles of the three camera components 6. In this implementation, it should also be noted that each set of camera components 6 only acquires the light that has passed through the corresponding window component 2 and been reflected by the image stabilization component 5; light entering from other window component 2 positions is not received.

[0044] In this embodiment, the airtightness of the cabin 1 is ensured by sealing the window assembly 2 and the opening 11; and the reliable imaging of the monitored target is ensured by allowing each image stabilizing assembly 5 to accept only the incoming light within its incident field of view, thus guaranteeing the imaging quality.

[0045] like Figure 2 The cabin 1 is also equipped with a heat dissipation component 4, which is used to dissipate heat from the processing and control components inside the cabin 1 to ensure the reliability of the shooting process. With the heat dissipation component 4 in place, the heat dissipation component 4 and the cabin 1 are also kept in a sealed connection to ensure the reliable sealing of the cabin 1.

[0046] Based on any of the above embodiments, please refer to Figure 1 , Figure 2 The window assembly 2 has at least two components, each corresponding to one of the two openings 11, and corresponding to at least two camera assemblies 6 and at least two image stabilization assemblies 5. Each window assembly 2 is sealed to the opening 11 to ensure a reliable sealing effect of the cabin 1 and thus guarantee image quality.

[0047] Please refer to Figure 6The vertical angle formed between the planar angle of each window component 2 and the center line L1 of the field of view of a single image-stabilized component 5 is α, where α = 90° - 2 / β, and β is the field of view angle of the camera component 6. Since the image-stabilized component 5 can reflect light to the position of the camera component 6, the field of view angle of the camera component 6 is also the viewing angle formed by the incident field of view of the image-stabilized component 5. Figure 6 In this context, β is directly defined as the field of view angle of camera component 6.

[0048] like Figure 6 As shown, the vertical angle between the center line of the field of view L1 and the plane angle of the window component 2 is α. Figure 6 As can be seen, the three field-of-view center lines corresponding to the incident field of view of the three image stabilization components 5 are the solid line L1, the dashed line L1, and the dotted line L1, which are located in the middle from top to bottom. By limiting the vertical angle α = 90° - 2 / β, the light from the monitored target can be prevented from entering the cabin 1 through reflection by the window component 2, thus ensuring the imaging quality of the camera component 6.

[0049] If the field of view β of a single camera component 6 is 15°, then the vertical angle α can be set to 82.5°.

[0050] In this embodiment, considering that the window transmittance of the window component 2 is not 100%, and that some light may be reflected into the cabin 1, a specific method for calculating the vertical angle is set to reduce the light reflected into the cabin 1 and ensure imaging quality.

[0051] In this embodiment, it should be noted that the center line of the field of view of the camera component 6 is actually the center line of the reflected field of view range after reflection by the image stabilization component 5. This center line and Figure 6 L1 in the diagram is not the same centerline.

[0052] Based on any of the above embodiments, the window assembly 2 includes a window lens 21 and a retaining ring 22 located circumferentially around the window lens 21. It should be noted that the retaining ring 22 does not interfere with the light path entering the cabin 1 through the window assembly 2.

[0053] The pressure ring 22 can seal the window lens 21 to the opening 11 of the cabin 1. Specifically, the inner ring of the pressure ring 22 is tightly attached to the surface of the window lens 21, and the outer ring of the pressure ring 22 is attached to the edge of the opening 11 of the cabin 1 and can be reliably fastened by fasteners.

[0054] Furthermore, to ensure the airtightness between the window assembly 2 and the opening 11 of the cabin 1, a sealing element 23 can be added at the opening 11, such as... Figure 3 As shown, a receiving groove 12 is provided on the inner wall at the opening 11, such as... Figure 3The receiving groove 12 is used to accommodate the sealing element 23. The sealing element 23 prevents rainwater from entering the cabin 1 from the opening 11, ensuring the reliable operation of the imaging module 01. After the window lens 21 is installed at the opening 11 by the pressure ring 22, the sealing element 23 is pressed into the receiving groove 12 to ensure a reliable sealing effect between the window assembly 2 and the cabin 1.

[0055] Based on any of the above embodiments, a plurality of drain holes 221 are provided at at least one edge of the pressure ring 22. The drain holes 221 can drain liquid or mixture on the window lens 21 into the window assembly 2, so as to avoid affecting the imaging effect of the imaging module 01.

[0056] Taking one specific embodiment as an example, if the pressure ring 22 has a square structure, then several drain holes 221 can be provided at the lower edge of the square structure, so that the liquid or mixture of impurities on the window lens 21 can be discharged through the drain holes 221 under the action of gravity. Alternatively, drain holes 221 can be provided at the lower edge and left and right edges of the square structure, so that the liquid or mixture on the window lens 21 can be discharged in multiple directions, which can be used in harsh weather, such as windy and rainy weather with heavy rainfall, to ensure the environmental adaptability of the monitoring equipment and the applicability of the monitoring equipment. The mixture in the above process can specifically be a mixture of water and impurities such as dust.

[0057] The square structure of the pressure ring 22 described above is only an example. The actual shape of the pressure ring 22 can be flexibly changed according to the actual situation and is not limited to this shape.

[0058] Based on any of the above embodiments, the drain outlet 221 has a guide surface 222 for draining liquid from the window lens 21.

[0059] The guide surface 222 provides a guiding function. For example, if a transition arc surface or transition slope is provided at the corresponding position of the drain outlet 221 and the edge of the window lens 21, it can ensure that liquid or mixture on the window lens 21 can smoothly enter the drain outlet 221 for reliable discharge. If an inclined plane is provided in the drain outlet 221 for guiding, it can ensure that liquid or mixture entering the drain outlet 221 can be discharged smoothly and reliably.

[0060] In one specific implementation, please refer to Figure 5 The guide surface 222 is an inclined plane, parallel to the plane of the window lens 21, allowing liquids or impurities on the window lens 21 to drain smoothly through the drain outlet 221. The structure is simple and reliable. The specific inclination angle of the inclined plane can be determined according to actual conditions and is not limited. The guide surface 222 is trapezoidal, such as... Figure 5As shown, this allows liquid or impurities on the window lens 21 to be quickly discharged through the trapezoidal guide surface 222, improving drainage efficiency, and the trapezoidal surface design avoids interference with the window lens 21.

[0061] by Figure 4 For example, along the drainage direction of the drain outlet 221, the diameter of the drain outlet 221 gradually decreases, ensuring that rainwater or mixtures are discharged quickly while providing a guiding effect.

[0062] Based on any of the above embodiments, please refer to Figure 1 The top of the cabin 1 is also equipped with a sunshade 3.

[0063] The sunshade 3 can be integrally formed with the cabin body 1 to ensure a good sealing effect. Based on the integral forming, a coating for resisting solar radiation can be set on the surface of the sunshade 3 to avoid direct sunlight, reduce the radiation temperature of the cabin body 1, and avoid affecting the shooting effect of the imaging module 01.

[0064] The sunshade 3 ensures the imaging effect of the imaging module 01, avoids direct sunlight, and reduces the radiation temperature of the cabin 1. The shape of the sunshade 3 is not limited, and its coverage area exceeds that of any window to ensure the overall imaging effect of the imaging module 01.

[0065] Based on the above embodiments, please refer to Figure 2 If the sun visor 3 is detachably connected to the cabin 1, then the material of the sun visor 3 can be made of radiation-proof material, ensuring a more reliable sunshade effect and avoiding affecting the shooting effect of the imaging module 01. However, it should be noted that when the sun visor 3 and the cabin 1 are set up separately, a sealing measure needs to be set between the sun visor 3 and the cabin 1. The specific sealing measure includes, but is not limited to, a sealing ring, to prevent rainwater and impurities from entering the cabin 1 and affecting the reliable operation of the imaging module 01. Of course, if the top of the cabin 1 is kept sealed, and if the cabin 1 is detachably connected to the cabin 1 by means of a ring clamp or a snap-fit, then no sealing measure is required. The specific setting can be determined according to the actual scenario.

[0066] Based on any of the above embodiments, please refer to Figure 2 The edge of the sunshade 3 is positioned to avoid obstructing the light entering the cabin 1 from several window components 2, thus preventing the sunshade 3 from interfering with the process of light from the monitored target entering the cabin 1 through the window components 2 and ensuring the quality of the image capture. This effect can be achieved by determining the shape, size, and thickness of the sunshade 3 during the actual design phase based on field-of-view analysis and solar radiation analysis, ensuring reliable performance.

[0067] In addition to the cabin structure described in the above embodiments, this utility model also provides a panoramic monitoring device including a cabin structure. The panoramic monitoring device should also be equipped with a rotating component, which can realize the circumferential rotation of the imaging module for image acquisition. For other structures of the panoramic monitoring device, please refer to the relevant technology for details, which will not be repeated here.

[0068] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0069] The above provides a detailed description of the cabin structure and panoramic monitoring equipment provided by this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
