Abstract
Description
Technical Field
[0001] This application relates to the field of automotive monitoring technology, and in particular to an in-vehicle panoramic camera, a vehicle monitoring system, and an automobile. Background Technology
[0002] The automotive industry is developing rapidly, and various video monitoring systems are used in vehicles, such as DVRs (Dashcams), DMSs (Driver Monitoring Systems), and OMSs (Occupant Monitoring Systems). These video monitoring systems are all equipped with corresponding cameras. For example, DVRs use forward-facing cameras, installed inside or outside the vehicle cabin, to record video and audio of the entire driving process. DMS cameras are mounted facing the driver's area inside the cabin to capture video of the driver. OMS cameras are mounted facing the non-driver's area inside the cabin to capture video of passengers.
[0003] However, existing video monitoring systems for vehicles use cameras that are independently configured, with limited functionality and cannot be integrated. This leads to an increase in the total number of cameras on the vehicle, higher costs, more in-vehicle communication channels, and greater computational demands when processing the video data captured by the cameras.
[0004] The existing technology for vehicle video monitoring systems addresses the problem that each camera is independently installed, with limited functionality and no ability to be integrated. This leads to an increase in the total number of cameras in the vehicle, higher costs, more in-vehicle communication channels, and greater computational demands for processing the video data collected by the cameras. Currently, no effective solution has been proposed. Utility Model Content
[0005] This invention provides a vehicle-mounted panoramic camera, a vehicle monitoring system, and a vehicle, addressing at least the technical problems of existing video monitoring systems for vehicles, where each camera is independently installed, has a single function, and cannot be integrated. This leads to an increase in the total number of cameras in the vehicle, higher costs, more in-vehicle communication channels, and greater computational power consumption when processing the video data collected by the cameras.
[0006] According to one aspect of this application, a vehicle-mounted panoramic camera is provided, comprising: a panoramic ring lens and an image sensor. The image sensor is located on the image-side of the panoramic ring lens, and the panoramic ring lens includes a panoramic ring head unit and a subsequent lens group arranged from the object-side to the image-side.
[0007] According to another aspect of this application, a vehicle monitoring system is provided, comprising: an in-vehicle panoramic camera as described above, and a processor device communicatively connected to the in-vehicle panoramic camera.
[0008] According to another aspect of this application, an automobile is provided, including the vehicle monitoring system described above.
[0009] Therefore, the vehicle-mounted panoramic camera provided in this application embodiment includes a panoramic surround lens and an image sensor, with the image sensor located on the image side of the panoramic surround lens. Thus, the vehicle-mounted panoramic camera can capture panoramic surround video images of the vehicle. This integrates the three functions of DMS (Driver Monitoring System), OMS (Occupant Monitoring System), and DVR (Dashcam) into a single vehicle-mounted panoramic camera within the limited space of a vehicle environment. This solves the technical problem in the prior art where each video monitoring system for a vehicle is independently configured, with limited functionality and no ability to be integrated. This leads to an increase in the total number of cameras in the vehicle, higher costs, more in-vehicle communication channels, and greater computational power consumption when processing the video data captured by the cameras.

[0021] Figure 1 and Figure 2 This is a schematic diagram of a vehicle-mounted panoramic camera 100 according to an embodiment of this application.
[0022] refer to Figure 1 As shown, the vehicle-mounted panoramic camera 100 is installed on the roof at the front of the vehicle body 200. Preferably, the vehicle-mounted panoramic camera is positioned between the driver's seat and the passenger seat at the front of the vehicle body 200.
[0023] Figure 2 A structural schematic diagram of the vehicle-mounted panoramic camera 100 is further shown. (Reference) Figure 2As shown, the vehicle-mounted panoramic camera 100 includes a panoramic ring lens LENS and an image sensor SEN, wherein the image sensor SEN is located on the image side of the panoramic ring lens LENS. Furthermore, the panoramic ring lens LENS includes a panoramic ring head unit PAL and a subsequent lens group RL arranged from the object side to the image side.
[0024] in Figure 3 A schematic diagram showing a panoramic surround video image captured by a vehicle-mounted panoramic camera 100 is provided. (Reference) Figure 3 As shown, the lower half of the image is the video image of the front of the vehicle, the upper right half is the video image of the driver's seat, and the upper left half is the video image of the passenger seat. Therefore, a panoramic video image captured by the vehicle-mounted camera 100 can include the video images captured by the DVR, DMS, and OMS monitoring devices. Subsequent image processing equipment only needs to perform simple image cropping operations to extract the video images corresponding to the DVR, DMS, and OMS respectively.
[0025] in Figure 4 The video images obtained by cropping and stitching from the vehicle-mounted panoramic camera 100 are shown, displaying video images of the driver's seat, the front of the vehicle, and the passenger seat from left to right.
[0026] As described in the background section, existing video monitoring systems for vehicles use cameras that are independently configured, have limited functionality, and cannot be combined. This results in an increase in the total number of cameras in the vehicle, higher costs, more in-vehicle communication channels, and greater computational power required to process the video data collected by the cameras.
[0027] In view of this, this application provides a vehicle-mounted panoramic camera 100. Since the vehicle-mounted panoramic camera 100 includes a panoramic ring lens LENS and an image sensor SEN, and the image sensor SEN is located on the image side of the panoramic ring lens LENS, the vehicle-mounted panoramic camera 100 can capture panoramic ring video images of the vehicle.
[0028] This allows for the integration of three functions—DMS (Driver Monitoring System), OMS (Occupant Monitoring System), and DVR (Dashcam)—into a single in-vehicle panoramic camera within the limited space of an in-vehicle environment, effectively reducing the number of hardware devices. This necessitates only one installation location, providing greater flexibility for the vehicle's interior layout and avoiding the installation difficulties caused by multiple devices competing for space.
[0029] Furthermore, for automakers, reducing the installation space required for hardware equipment helps optimize the overall interior design of the vehicle. This allows for a cleaner, more aesthetically pleasing interior without sacrificing functionality, enhancing the user experience. In terms of hardware costs, in-vehicle panoramic cameras offer a significant advantage in material procurement costs compared to three separate cameras. This is because mass-producing a single, multi-functional camera leverages economies of scale, reducing the production cost per unit. For example, it reduces the number of components such as camera housings and lenses required, while also reducing costs on core components like chipsets through integrated functionality.
[0030] Furthermore, reducing the number of cameras installed reduces installation time and the use of related accessories (such as connecting cables and mounting brackets). This not only lowers direct costs in the car production process but also indirectly reduces after-sales maintenance costs that might result from installing multiple devices.
[0031] Furthermore, from the perspective of in-vehicle electronic systems, a single three-in-one camera only requires one interface to communicate with the vehicle's central control system, significantly simplifying the system's connection complexity compared to three separate cameras. This makes the wiring of the vehicle's electronic systems simpler and reduces the risk of wiring failures.
[0032] Furthermore, at the software level, the control and data processing of the three-in-one camera can be carried out within a relatively unified software framework, reducing the complexity of interaction between software modules. For example, the system can use an algorithm to initially filter and classify the data collected by the camera, and then distribute it to the corresponding DMS, OMS, and DVR functional modules for processing, thereby improving the software's operating efficiency and stability.
[0033] Furthermore, in terms of after-sales maintenance, only one camera device needs maintenance and updates. Whether it's hardware fault repair or software upgrade, technicians only need to operate on one device, reducing maintenance workload and repair time. For car owners, it's also easier to understand and manage the monitoring devices in their vehicles. For example, when a problem occurs, the owner only needs to focus on the status of one camera, rather than checking three cameras with different functions separately, improving the user experience.
[0034] This solves the technical problem in existing technologies where each video monitoring system for a vehicle is independently configured, has a single function, and cannot be integrated. This leads to an increase in the total number of cameras in the vehicle, higher costs, more in-vehicle communication channels, and greater computational power consumption when processing the video data collected by the cameras.
[0035] Optionally, the panoramic ring head unit includes a first lens PAL1 and a second lens PAL2 arranged sequentially from the object side to the image side. The first lens PAL1 is a meniscus lens with positive optical power, and the second lens PAL2 is a biconvex lens with positive optical power. The convex surface of the first lens PAL1 faces the object side, and the concave surface faces the image side. Furthermore, the subsequent lens group includes a third lens RL1, a fourth lens RL2, a fifth lens RL3, and a sixth lens RL4 arranged sequentially from the object side to the image side, wherein the fifth lens RL3 and the sixth lens RL4 form a cemented lens.
[0036] Optionally, the radius of curvature of the first surface A1 of the first lens PAL1 on the object side is 16.90–18.50 mm, the radius of curvature of the reflecting surface (A6) on the object side is -28.90–34.90 mm, and the radius of curvature of the second surface A2 on the image side is 24.00–26.00 mm. The main function of the first surface A1 of the first lens PAL1 is to initially collect the field of view light through refraction. Therefore, the first surface A1 should have sufficient curvature to ensure that the light can be received by the fourth surface A3 of the second lens on the image side after refraction. At the same time, since the refraction of light in a large field of view will introduce large optical aberrations, the radius of curvature of the first surface A1 of the first lens PAL1 should not be too small. The second surface A2 on the image side is the double-cemented surface of the panoramic ring head unit. Its function is to match the materials of the first lens PAL1 and the second lens PAL2, and reduce the chromatic aberration introduced into the overall lens by adjusting the optical power of the two lenses simultaneously. The radius of curvature of the third surface A4 of the second lens on the object side is 24.00–26.00 mm, and the radius of curvature of the fourth surface A3 on the image side is -8.90–-7.90 mm. The radius of curvature of the fourth surface A3 on the image side of the second lens is -8.90–-7.90 mm, and the radius of curvature of the reflecting surface A6 of the first lens on the object side is -28.90–-34.90 mm. The third surface A3 and the reflecting surface A6 use reflection to compress the angle of light rays in a large field of view, making it closer to the optical axis, which facilitates aberration correction by subsequent lenses. The radii of curvature of both lenses (A3 and A6) should be selected to ensure they have the same sign, minimizing the field curvature effect introduced by the panoramic ring head unit. The radius of curvature of the fifth surface B1 of the third lens RL1 on the object side is -2.85 to -2.25 mm, and the radius of curvature of the sixth surface B2 on the image side is -4.30 to -2.90 mm. Using a meniscus lens near the pupil, which conforms to the light transmission trend, can specifically correct spherical aberration in the system. The radius of curvature of the seventh surface C1 of the fourth lens RL2 on the object side is 12.50 mm. The eighth surface C2, located on the image side, has a radius of curvature of -8.10 to -6.00 mm, which is used to further balance spherical aberration in the lens; the ninth surface D1 of the fifth lens RL3, located on the object side, has a radius of curvature of 7.00 to 8.20 mm, and the tenth surface D2, located on the image side, has a radius of curvature of -5.60 to -4.20 mm; and the sixth lens RL4 has an object side surface that coincides with the tenth surface D2, and the eleventh surface D3, located on the image side, has a radius of curvature of 36 to 42 mm.
[0037] Optionally, the center thickness of the first lens PAL1 is 6.49 mm; the center thickness of the second lens PAL2 is 6.37 mm; the center thickness of the third lens RL1 is 1.52 mm, and the third lens RL1 adopts a thick meniscus structure, which can effectively compensate for the residual field curvature of the panoramic ring head unit; the center thickness of the fourth lens RL2 is 2.76 mm; the center thickness of the fifth lens RL3 is 1.60 mm; and the center thickness of the sixth lens RL4 is 3.50 mm.
[0038] Optionally, the refractive index of the first lens PAL1 is 1.63 to 1.67; the refractive index of the second lens PAL2 is 1.63 to 1.67, and the refractive index of the second lens PAL2 should be close to that of the first lens PAL1 to avoid total internal reflection at the overlapping surface; the refractive index of the third lens RL1 is 1.81 to 1.87; the refractive index of the fourth lens RL2 is 1.63 to 1.69; the refractive index of the fifth lens RL3 is 1.62 to 1.69; and the refractive index of the sixth lens RL4 is 1.81 to 1.87.
[0039] Optionally, the Abbe number of the first lens PAL1 is 54-62; the Abbe number of the second lens PAL2 is 54-62; the Abbe number of the third lens RL1 is 22-26; the Abbe number of the fourth lens RL2 is 55-60; the Abbe number of the fifth lens RL3 is 57-62; and the Abbe number of the sixth lens RL4 is 22-26. Using a sixth lens with a significantly different Abbe number from the fifth lens RL3 for cementation can reduce chromatic aberration of the optical system while ensuring the optical power of the lens group.
[0040] Optionally, the effective half-aperture of the first lens PAL1 is 11.00–13.00 mm; the effective half-aperture of the second lens PAL2 is 5.00–7.50 mm; the effective half-aperture of the third lens RL1 is 0.70–1.20 mm; the effective half-aperture of the fourth lens RL2 is 1.50–2.10 mm; the effective half-aperture of the fifth lens RL3 is 1.70–2.40 mm; and the effective half-aperture of the sixth lens RL4 is 1.80–2.20 mm.
[0041] Specifically, Table 1 shows a schematic diagram of the parameters of each facet of the panoramic ring lens. For the facet labels in Table 1, please refer to [link to Table 1]. Figure 5 The face labels of each face in the middle.

[0045] Furthermore, according to another aspect of this embodiment, a vehicle monitoring system is provided, with reference to... Figure 1 and Figure 6 As shown, the vehicle monitoring system includes: an in-vehicle panoramic camera 100 as described in any of the above, and a processor device 310 that is communicatively connected to the in-vehicle panoramic camera 100.
[0046] Optionally, the system also includes an infrared supplementary light source 320, a temperature sensor 330, and a microphone 340 that are communicatively connected to the processor device 310.
[0047] The infrared supplementary light source 320 emits infrared light under low-light conditions (such as at night or in tunnels). Since infrared light is invisible to the human eye but can be detected by the camera's image sensor, it allows for clear acquisition of images inside and outside the vehicle even in dark environments. For the DMS (Driver Monitoring System) function, it better monitors the driver's condition; for the OMS (Occupant Monitoring System) function, it effectively observes passenger behavior; and for the DVR (Dashcam) function, it improves the visibility of the dashcam at night. The infrared supplementary light source 320 can use the near-infrared (NIR) band, with a wavelength range typically between 780-2500nm. Infrared light in this band is safe for the human eye and can be well received by most image sensors, while also having good penetration, reducing the impact of environmental factors (such as fog and dust) on imaging. When driving at night, the infrared supplementary light automatically activates when the vehicle enters an area with poor lighting conditions. For the DMS component, it can clearly capture details such as the driver's facial expressions and eye movements, accurately determining whether there is fatigue or distracted driving. For the OMS component, it can observe whether there are abnormal movements or sudden situations involving passengers inside the vehicle. In the footage recorded by DVR, pedestrians, vehicles, and road signs on the road can be recorded more clearly, providing more complete information for accident analysis and other purposes.
[0048] Microphone 340 can collect in-vehicle sound information, such as conversations between the driver and passengers, vehicle operating sounds (e.g., engine and tire sounds), and external environmental sounds (e.g., alarms and horns from other vehicles). This sound data can be combined with image data to provide richer information. Microphone 340 operates based on sound-to-electrical conversion. When sound waves cause the microphone 340 diaphragm to vibrate, the sound signal is converted into an electrical signal through electromagnetic induction or capacitance changes. After amplification and digitization, it can be recorded or transmitted. In terms of DMS (Driver Monitoring System), if signs of driver fatigue are detected, and the microphone 340 also captures the sound of the driver yawning, the accuracy of the judgment can be enhanced. For OMS (Occupational Monitoring System), when passengers argue or make unusual sounds due to sudden illness, microphone 340 can promptly capture this information and use it along with image data as evidence or to trigger appropriate safety mechanisms. In DVR (Dual Audio Recording) functionality, recorded sound can help reconstruct the scene of an accident, such as the sound of a collision or emergency braking, which plays an important auxiliary role in determining accident liability.
[0049] The temperature sensor 330 can detect the camera's own temperature and the temperature of the surrounding environment (inside or outside the vehicle). By monitoring the temperature, it can prevent the camera from being damaged by overheating and provide a reference for image optimization. For example, the performance of the image sensor may vary under different temperature conditions; temperature compensation can make the image quality more stable. Common temperature sensors 330 include thermocouples and thermistors. Thermocouples are based on the Seebeck effect, measuring temperature through the thermoelectric potential difference between two different metals; thermistors measure temperature by utilizing the characteristic that their resistance changes with temperature. In hot weather, when the temperature sensor 330 detects that the camera temperature is too high, it can activate a heat dissipation mechanism (such as fan cooling or reducing the camera's operating power) to ensure the camera's normal operation. At the same time, it can dynamically adjust parameters such as image sensor gain and exposure time according to changes in ambient temperature. For example, in cold environments, the exposure time can be appropriately increased to compensate for the decrease in image sensor sensitivity caused by the temperature drop, thereby ensuring the image quality of DMS, OMS, and DVR functions.
[0050] Alternatively, according to another aspect of this embodiment, an automobile is provided, including the vehicle monitoring system described in any of the above embodiments.
[0051] Therefore, the vehicle-mounted panoramic camera provided in this application embodiment includes a panoramic surround lens and an image sensor, with the image sensor located on the image side of the panoramic surround lens. Thus, the vehicle-mounted panoramic camera can capture panoramic surround video images of the vehicle. This integrates the three functions of DMS (Driver Monitoring System), OMS (Occupant Monitoring System), and DVR (Dashcam) into a single vehicle-mounted panoramic camera within the limited space of a vehicle environment. This solves the technical problem in the prior art where each video monitoring system for a vehicle is independently configured, with limited functionality and no ability to be integrated. This leads to an increase in the total number of cameras in the vehicle, higher costs, more in-vehicle communication channels, and greater computational power consumption when processing the video data captured by the cameras.

Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.
