Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings. The drawings are only schematic and are not drawn to scale.

FIG. 1 schematically illustrates an automobile rearview mirror according to an embodiment of the present invention, in which a vehicle monitoring system is integrated, which is mainly used for monitoring people, property, and the like inside the vehicle.

As can be seen from the figure, the car's interior mirror is used as an example in this description. Those skilled in the art can understand that FIG. 1 is only an example form. Therefore, the rear-view mirror mentioned in the present invention is also applicable to the left and right rear-view mirrors of a car, and even the makeup mirror (which can also serve as a rear-view mirror). The role of the mirror) and so on. It can be thought that when the new vehicle monitoring system is integrated in different rearview mirrors, different optimal data acquisition angles can be guaranteed. When the vehicle monitoring system is integrated in the interior mirror of a car, it can better obtain the maximum viewing angle range of the interior monitoring camera.

Not only that, the vehicles mentioned in the new model may also include vehicles such as city buses, coaches, and even trains that may need to be monitored inside and outside the vehicle.

The rearview mirror body 1 of the rearview mirror is shown schematically in FIG. 1, and a fixing base 2 and a bracket 3 for fixing it to a front windshield of a car, and a corresponding power cord, control line or data transmission. Wires, etc. and their connectors 4. The connector 4 may include a vehicle monitoring processing interface and a vehicle monitoring power supply interface communicating with the data line 8.

In addition, as can be seen from the figure, the vehicle monitoring system according to the present invention also includes a camera device 5, a natural light mirror 6, an infrared light mirror 7, and the like, all of which are installed in the rear mirror of the vehicle and are located in the mirror of the rear mirror The rear of the camera not only does not affect the aesthetics, but also has hidden features. Specifically, the video recording device 5 can be mounted on the rear case of the rear view mirror, for example, by gluing, screwing, or snapping. The camera 5 may be a full-time high-definition camera. The data line 8 is also shown in the figure. The data line 8 can transmit the image data collected by the video recording device 5 to the controller or the terminal data storage device, and can transmit the instructions of the controller to the lens switching device (not shown). Show). The data line 8 extends through the bracket 3 of the rear view mirror, and is connected to an external controller, a power source, and the like through a connector 4. It is conceivable that the data line 8 can also be replaced in a wireless manner. The lens switching device is used to switch the natural light mirror 6 and the infrared light mirror 7 to adapt to monitoring when the brightness of different environments is different; this specification will be described in more detail later.

The camera 5 can be arranged to face the position to be monitored of the vehicle. In this embodiment, according to different monitoring needs, the camera can be oriented toward the front or rear seats of the vehicle, or the central armrest box, glove box, etc. where valuables may be stored. In addition, when the new monitoring system is applied to exterior rearview mirrors, etc., the camera can be oriented toward a certain body part outside the vehicle. In these cases, the aforementioned to-be-monitored positions are the front or rear seats of the vehicle, the center armrest box, the glove box, the corresponding exterior body parts, etc., which may be determined according to the needs of monitoring in specific implementations.

It can be understood that the orientation of the camera can also be set to be adjustable, so that different parts of the vehicle can be monitored as needed. Those skilled in the art can understand that the camera device mentioned in this manual will include functions such as taking pictures, video, or photography (such as a full-time high-definition camera), which can record still images and dynamic images, and also provide recording function.

The natural light mirror 6 and the infrared light mirror 7 can be used to provide a filtering function for the lens of the recording device, and thus can be adjusted before the recording device (and after the lens of the rear view mirror) as needed. It can be understood that by switching between the natural light mirror and the infrared light mirror in front of the camera lens, the camera device can be adapted to different ambient brightness, and clear images can always be recorded.

For example, a natural light mirror will allow natural light to pass through, and may filter out infrared light that is not natural light, etc., so that the camera can record a clearer image when the natural light intensity is high during the day. In contrast, infrared mirrors filter out natural light and allow infrared light to pass through, making it possible to record at night, dusk, dawn when there is insufficient natural light, or when the vehicle is in the shade of a tree shade, a building shadow, or the shadow of a natural object. Very clear images in order to provide the best front-end data acquisition quality for terminal data storage and monitoring.

In order to switch the natural light mirror and the infrared light mirror more conveniently and concealed under different ambient brightness, the embodiments in this application provide a light mirror switching mechanism for a vehicle monitoring system. For example, the light mirror switching mechanism may be an automatic driving device such as a motor.

The light mirror switching mechanism may be set to switch the natural light mirror between the lens of the camera and the rear view mirror and the infrared light mirror from the camera and the rear view mirror when the brightness of the position to be monitored is higher than the first brightness. Switch between the lenses, or switch the infrared light mirror between the lens of the camera and the rear view mirror when the brightness of the position to be monitored is lower than the second brightness (the second brightness is not higher than the aforementioned first brightness) And switch the natural light mirror from the lens of the camera and the rearview mirror. For example, in an optional implementation manner, in order to switch to different light mirrors during the day and night, the first brightness and the second brightness may be brightness between the natural light brightness during the day and the natural light brightness at night. In other optional implementations, at least one of the first brightness and the second brightness may be natural light brightness at dusk or dawn or in some shadows (such as, but not limited to, cloudy, tree shade, building shadow, etc.) The natural brightness at the time of down. It is conceivable that the first brightness may be set equal to the second brightness. It can be understood that although there is no specific brightness threshold in this specification, those skilled in the art can fully understand the concept of the novel model, and can set specific brightness thresholds as needed.

In a specific example, while the user uses the rear-view mirror with the new-type vehicle monitoring system, the vehicle monitoring system can distinguish between daytime and nighttime states by program algorithms to switch between natural light mirrors and infrared light mirrors. For example, the control device for the light-mirror switching mechanism may determine a change in ambient brightness according to a change in the quality of a recorded image of the recording device, thereby switching between a natural light mirror and an infrared light mirror to implement full-time day and night monitoring. In a specific implementation manner, the determination of the image quality may be determined by, for example, the amount of noise of the image after the super exposure.

In order to facilitate the switching between the natural light mirror and the infrared light mirror, in the illustrated embodiment, the natural light mirror and the infrared light mirror are spelled into a disc shape. The disc can be mounted on a rotating shaft fixed to the rear case of the rear-view mirror, and can be rotated relative to the rotating shaft. It can be seen that the disc is biased relative to the camera. The light mirror switching mechanism only needs to drive the disc to rotate in one direction to switch between the natural light mirror and the infrared light mirror. Remove it before or from the camera. The advantages of this rotary light mirror switching device are simple structure, stability and durability, and long service life. It can ensure that the light collection transmission mirror can be switched reliably after the ambient brightness changes, which meets the needs of full-time day and night camera collection monitoring. It can be understood that when a motor is used to drive the rotation of the disc, a reduction mechanism, a control device, and the like can also be provided. For the needs of installation, these light mirror switching mechanisms, speed reduction mechanisms, and controller devices may also be provided outside the rearview mirror. For the need of concealment, in an alternative embodiment, they can also be arranged inside the rearview mirror and behind the mirror glass. These reduction mechanisms may be, for example, but not limited to, gear transmission, worm gear transmission, belt transmission, chain transmission, and the like.

In other embodiments, the natural light mirror and the infrared light mirror can also be made into any shape such as a rectangle; the switching method can also be set to move up and down or left and right to achieve the switch (the natural light mirror and infrared light mirror in this illustration can achieve left and right Mobile switching) and so on. It can be seen that those skilled in the art can think of other natural light mirrors and infrared light mirrors in the shape and arrangement manner and switching manner, which cannot be exhaustive, and will not be repeated here.

In order to achieve the concealment requirements required for monitoring and do not affect the normal use of the rearview mirror, you can use a unidirectional transparent sheet to make the mirror of the rearview mirror, or at least block the camera, natural light mirror and infrared light mirror. The lens 9 of the rear-view mirror at the area is a unidirectional light-transmitting sheet. It can be understood that such a setting effectively avoids the impact on the field of vision of a normal rearview mirror. When the user normally uses the inside rearview mirror, the user will not notice the hidden surveillance camera device and the light mirror switching mechanism, which can ensure the user's need for the use of the rearview mirror field of vision.

Based on the above teachings, those skilled in the art can understand how to integrate the new vehicle monitoring system into the rearview mirror, and obtain a vehicle with such a rearview mirror and a method for monitoring the vehicle using the aforementioned vehicle monitoring system.

According to the above description, it can be understood that the new model solves the problem of great difference in the quality of daytime and nighttime surveillance cameras in traditional automotive products. The new model provides a full-time vehicle monitoring system. After switching between day and night, or after switching between light and dark, there is a significant change in quality information such as image sharpness. The hidden camera device is based on the collected image. Quality change, through identification of the quality of the image, adapting to environmental changes, without the need for user operation, the judgment of day and night conditions or bright and dark conditions is realized, and the quality of the image is rapidly depleted at night or in the dark. Triggering conditions, triggering the infrared light mirror to automatically switch to the lens of the recording device, greatly improving the vehicle's monitoring ability at night or in the dark, and automatically switching back to the visible natural light mirror after the vehicle is turned back to the day or the bright place. At the same time, the quality of daytime and nighttime monitoring is guaranteed to meet the needs of full-time clear image collection and monitoring of passengers and belongings inside and outside the vehicle, to maximize the effect of camera monitoring.

FIG. 2 is an example of a daylight natural light mirror monitoring image. FIG. 3 is an example of a night-time natural light mirror monitoring image. FIG. 4 is an example of an image monitored by an infrared light mirror at night. It can be seen directly from the figure that there is no doubt that the monitoring image of daytime natural light mirrors is very clear, and at the same time, the image quality of nighttime infrared light mirror monitoring images is greatly improved compared with the nighttime natural light mirror monitoring images.

Considering that the rear-view mirrors of most cars are connected with a sensor for sensing light intensity, the threshold value of the sensing signal of the existing light sensor can also be used in the example of the new model. To switch between natural light mirrors and infrared light mirrors.
