Description

Technical Field

[0001] This disclosure relates to the field of vehicle technology, and more particularly to a monitoring system for vehicles and a vehicle. Background Technology

[0002] To ensure driving safety and monitor the real-time status of drivers and passengers, an increasing number of vehicles are equipped with Driver Monitor Systems (DMS) and Occupant Monitor Systems (OMS). Because DMS and OMS monitor different objects, related technologies typically use two cameras inside the vehicle, one for DMS and one for OMS, requiring two complete sets of hardware and transmission channels, thus increasing costs. Using a wide-angle lens simultaneously for both DMS and OMS necessitates adding new distortion correction algorithms to existing technologies, further increasing development costs. Utility Model Content

[0003] To address the aforementioned technical problems, this disclosure provides a monitoring system and vehicle for vehicles, which improves monitoring accuracy and reduces costs.

[0004] In a first aspect, embodiments of this disclosure provide a monitoring system for a vehicle, comprising: a camera; the camera comprising: at least one first lens for capturing an image of a first region; at least one second lens for capturing an image of a second region, wherein the first region and the second region at least partially do not overlap; and an image sensor for simultaneously acquiring the images captured by the first lens and the images captured by the second lens to form a total image.

[0005] In some embodiments, the focal length of the first lens is a first focal length, the focal length of the second lens is a second focal length, and the first focal length is less than the second focal length.

[0006] In some embodiments, the camera further includes a reflective structure for simultaneously projecting images captured by the first lens and the second lens onto the image sensor.

[0007] In some embodiments, the reflective structure includes a reflective component for reflecting an image captured by the second lens and projecting it onto the image sensor.

[0008] In some embodiments, the first area includes a driver's area, and the second area includes a passenger area and a rear seat area.

[0009] In some embodiments, the first region includes the front seat region and the second region includes the rear seat region.

[0010] In some embodiments, the system further includes: an image processing chip, a controller, a central control screen, and a speaker. The image processing chip is electrically connected to an image sensor, and the controller is electrically connected to the image processing chip, the central control screen, and the speaker, respectively. The image processing chip is used to monitor the overall image. The controller is used to transmit the overall image to the central control screen. When the image processing chip detects abnormal features in the overall image, the controller is also used to control the speaker and the central control screen to output voice reminder information and display reminder information, respectively.

[0011] In some embodiments, the camera further includes at least one third lens for capturing images of a third region, the third region being at least partially non-overlapping with both the first region and the second region; and an image sensor for simultaneously acquiring images captured by the first lens, the second lens, and the third lens to form a total image.

[0012] In some embodiments, the first region includes a driver's area, the second region includes a front passenger area, and the third region includes a rear seat area.

[0013] Secondly, this disclosure also provides a vehicle, including the monitoring system provided in this disclosure.

[0014] The technical solution provided in this disclosure has the following advantages compared with the prior art: The monitoring system disclosed herein includes a camera, which comprises a first lens and a second lens. The first lens is used to capture images of a first area, and the second lens is used to capture images of a second area. The first and second areas do not overlap at least partially, meaning that the first and second lenses can capture images of different areas. The camera also includes an image sensor. Images captured by the first and second lenses can be simultaneously projected onto the image sensor, which can simultaneously acquire both images to form a total image. This allows for simultaneous monitoring of different areas through the collaboration of the two independent lenses (first and second) and the image sensor, which improves the monitoring range, eliminates the time delay in time-division monitoring in related technologies, and enhances monitoring accuracy. Furthermore, the image sensor's ability to simultaneously acquire both images to form a total image eliminates the need for complex algorithms, and only requires one image sensor in the camera, thus reducing costs.

Detailed Implementation

[0018] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0019] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0020] Figure 1 This is a schematic diagram of the structure of a monitoring system provided in an embodiment of this disclosure, with reference to... Figure 1 This embodiment provides a monitoring system, including: a camera 10; Camera 10 includes: At least one first lens 11, the first lens 11 being used to capture an image of a first region; At least one second lens 12 is used to capture an image of a second region, wherein the first region and the second region do not overlap at least partially; Image sensor 13 is used to simultaneously acquire images captured by the first lens 11 and the second lens 12 to form a total image.

[0021] Specifically, the monitoring system provided in this embodiment is applied to a vehicle. The monitoring system includes a camera 10, which is fixedly installed inside the vehicle. The camera 10 includes a first lens 11 and a second lens 12. The first lens 11 is used to capture images of a first area, and the second lens 12 is used to capture images of a second area. The first area and the second area do not overlap at least partially, meaning that the first lens 11 and the second lens 12 can capture images of different areas. The camera 10 also includes an image sensor 13. Images captured by the first lens 11 and the second lens 12 can be simultaneously projected onto the image sensor 13. The image sensor 13 can simultaneously acquire the images captured by the first lens 11 and the second lens 12 to form a total image. This allows for simultaneous monitoring of different areas through the collaboration of the two independent lenses (first lens 11 and second lens 12) and the image sensor 13. This improves the monitoring range and eliminates the time delay in time-division monitoring in related technologies, thus improving monitoring accuracy. Furthermore, the image sensor 13 can simultaneously acquire the images captured by the first lens 11 and the second lens 12 to form a total image, eliminating the need for complex algorithms. Since only one image sensor 13 is required in the camera 10, this reduces costs.

[0022] It should be noted that when the first lens 11 captures an image of the first area, it can be understood that the first lens 11 can capture an image of the first area relatively clearly, that is, the first area is within the focusing range of the first lens 11. Similarly, when the second lens 12 captures an image of the second area, it can be understood that the second lens 12 can capture an image of the second area relatively clearly, that is, the second area is within the focusing range of the second lens 12.

[0023] Figure 2 This is a schematic diagram of another monitoring system provided in this disclosure embodiment, see reference. Figure 2 In some alternative embodiments, the focal length of the first lens 11 is a first focal length, and the focal length of the second lens 12 is a second focal length, wherein the first focal length is less than the second focal length.

[0024] Specifically, the camera 10 includes a first lens 11 and a second lens 12. The focal length of the first lens 11 is shorter than that of the second lens 12, meaning the first lens 11 has a smaller focal length and is used to capture images of the near-end area. The second lens 12 has a larger focal length and is used to capture images of the far-end area. Both the first lens 11 and the second lens 12 are fixed-focus lenses. By using the first lens 11 and the second lens 12, images of the near-end area and the far-end area can be captured simultaneously, which helps to improve the monitoring range.

[0025] Continue to refer to Figure 2In some alternative embodiments, the camera 10 further includes a reflective structure 14 for simultaneously projecting the image captured by the first lens 11 and the image captured by the second lens 12 onto the image sensor 13.

[0026] Specifically, the camera 10 includes a first lens 11 and a second lens 12. The focal length of the first lens 11 and the focal length of the second lens 12 are different. By setting a reflection structure 14, the images captured by the first lens 11 and the second lens 12 are simultaneously projected onto the image sensor 13, so that the image sensor 13 can simultaneously acquire the images captured by the first lens 11 and the second lens 12 to form a total image.

[0027] Continue to refer to Figure 2 In some alternative embodiments, the reflective structure 14 includes a reflective component 142 for reflecting the image captured by the second lens 12 and projecting it onto the image sensor 13.

[0028] Specifically, the reflective structure 14 includes a reflective component 142. The image captured by the first lens 11 reaches the image sensor 13 directly through a parallel light path. The image captured by the second lens 12 reaches another area on the image sensor 13 after passing through the folding path of the reflective component 142. Thus, the images captured by the first lens 11 and the second lens 12 are simultaneously projected onto the image sensor 13, thereby enabling the image sensor 13 to simultaneously acquire the images captured by the first lens 11 and the second lens 12 to form a total image.

[0029] Optionally, the reflective assembly 142 includes two mirrors. The image captured by the second lens 12 is reflected twice by the reflective assembly 142 and then reaches the target area on the image sensor 13. The size of the two mirrors in the reflective assembly 142 can be adjusted according to the imaging area on the image sensor 13. The larger the imaging area required on the image sensor 13, the larger the size of the two mirrors in the reflective assembly 142 should be.

[0030] Optionally, the lens in the reflective assembly 142 can be a reflector or a polarizing filter. Of course, in other embodiments of this disclosure, the lens in the reflective assembly 142 can also be other optical structures, which will not be described in detail here.

[0031] In some alternative embodiments, the first area includes a driver's area, and the second area includes a passenger area and a rear seat area.

[0032] For details, please refer to [link / reference]. Figure 2The camera 10 can be fixed to the A-pillar of the vehicle. The first lens 11 captures the image of the driver's area, that is, the first lens 11 can capture the image of the driver. The second lens 12 captures the images of the passenger area and the rear seat area, that is, the second lens 12 can capture the images of the passengers in the passenger area and the rear seat area. That is, the camera 10 integrates DMS and OMS functions.

[0033] In some alternative embodiments, the first region includes the front seat area and the second region includes the rear seat area.

[0034] For details, please refer to [link / reference]. Figure 2 The camera 10 can be fixed to the rearview mirror of the vehicle. The first lens 11 captures the image of the front seat area, that is, the first lens 11 can capture the image of the passenger in the driver and front passenger areas. The second lens 12 captures the image of the rear seat area, that is, the second lens 12 can capture the image of the passenger in the rear seat area. That is, the camera 10 integrates DMS and OMS functions.

[0035] Figure 3 This is a schematic diagram of the structure of another monitoring system provided in this disclosure embodiment, see reference. Figure 3 In some optional embodiments, the monitoring system further includes: an image processing chip 20, a controller 30, a central control screen 40, and a speaker 50. The image processing chip 20 is electrically connected to the image sensor 13, and the controller 30 is electrically connected to the image processing chip 20, the central control screen 40, and the speaker 50, respectively. Image processing chip 20 is used to monitor the total image; Controller 30 is used to transmit the total image to the central control screen 40; Furthermore, when the image processing chip 20 detects abnormal features in the overall image, the controller 30 also controls the speaker 50 and the central control screen 40 to output voice reminder information and display reminder information, respectively.

[0036] Specifically, the monitoring system also includes an image processing chip 20, which is electrically connected to the image sensor 13. The image processing chip 20 can acquire and process the overall image in real time, thereby enabling it to monitor the overall image. The monitoring system also includes a controller 30, a central control screen 40, and a speaker 50. The controller 30 is electrically connected to the image processing chip 20, the central control screen 40, and the speaker 50, respectively. The controller 30 can transmit the overall image to the central control screen 40, which can then display the overall image. Simultaneously, when the image processing chip 20 detects abnormal features in the overall image, the controller 30 can control the speaker 50 and the central control screen 40 to output voice and display alerts, respectively.

[0037] Figure 4This is a schematic diagram of the structure of another monitoring system provided in this disclosure embodiment, see reference. Figure 4 In some optional embodiments, the camera 10 further includes at least one third lens 15, which is used to capture an image of a third region, the third region not overlapping at least partially with the first region and the second region, respectively; Image sensor 13 is used to simultaneously acquire images captured by first lens 11, second lens 12 and third lens 15 to form a total image.

[0038] Specifically, the camera 10 also includes a third lens 15, which is used to capture images of a third region. This third region does not overlap with the first region at least partially, nor with the second region at least partially. That is, the first lens 11, the second lens 12, and the third lens 15 can capture images of different regions. The image sensor 13 is used to simultaneously acquire images captured by the first lens 11, the second lens 12, and the third lens 15 to form a total image. This allows for simultaneous monitoring of different regions through the three independent lenses (first lens 11, second lens 12, and third lens 15) working in conjunction with the image sensor 13. This improves the monitoring range and eliminates the time delay in time-division monitoring in related technologies, thus enhancing monitoring accuracy. Furthermore, the image sensor 13 can simultaneously acquire images captured by the first lens 11, the second lens 12, and the third lens 15 to form a total image, eliminating the need for complex algorithms. Since only one image sensor 13 is required in the camera 10, this reduces costs.

[0039] It should be noted that the third lens 15 captures the image of the third region, which can be understood as the third lens 15 being able to capture the image of the third region relatively clearly, that is, the third region is within the focusing range of the third lens 15.

[0040] In some alternative embodiments, the first region includes a driver's area, the second region includes a passenger's area, and the third region includes a rear seat area.

[0041] Specifically, the first lens 11 captures an image of the driver's area, meaning the first lens 11 can capture an image of the driver; the second lens 12 captures an image of the passenger area, meaning the second lens 12 can capture an image of the passenger in the passenger area; and the third lens 15 captures an image of the rear seat area, meaning the third lens 15 can capture an image of the passenger in the rear seat area. In other words, the camera 10 integrates DMS and OMS functions.

[0042] It should be noted that, Figure 4The example shown in the document includes a first lens 11, a second lens 12, and a third lens 15. In other embodiments of this disclosure, the camera 10 may also include a greater number of first lenses 11, second lenses 12, and third lenses 15 to enable monitoring of more areas. These will not be described in detail here.
