The light supplementing lamps are also arranged at the back of the transparent area, and are arranged under the camera and symmetrically distributed, namely, two smaller and symmetrical circular areas in fig. 2 are the arrangement positions of the light supplementing lamps.

As can be seen from the block division example of the interior rear view mirror system shown in fig. 4, the interior rear view mirror system in this embodiment can be divided into an image acquisition and processing block 401 and an anti-glare function block 402.

The image acquisition and processing module 401 is composed of a camera 4011 (a high-resolution camera, that is, the camera in the above description), a light-compensating lamp 4012 (the light-compensating lamp in the above description), an algorithm unit 4013, and a circuit board 4014; the camera and the light supplementing lamp are arranged in the inner rearview mirror, and after the rear cover of the inner rearview mirror is covered, the camera and the light supplementing lamp are not easy to observe by eyes of people, so that the privacy is good.

The anti-glare function module 402 consists of a transparent lens 4021, an electrochromic lens 4022, an algorithm unit 4023 and a circuit board 4024; the electrochromic lens includes a first lens layer, an electrochromic layer, and a second lens layer.

The image acquisition and processing module is used for acquiring and processing the images of the personnel in the vehicle and the light source images of the coming vehicle behind, realizing the DMS function and the OMS function on the processed images of the personnel in the vehicle through an algorithm, and analyzing the light source images to obtain light intensity data such as light intensity values. The anti-dazzle function module compares a light intensity value (the light intensity of a light source of a vehicle coming from the rear) obtained by analysis from the light source image with a preset light intensity value, when the light intensity value is larger than the preset light intensity value, the anti-dazzle function is started, and the anti-dazzle functions of different grades are started according to the difference between the light intensity value and the preset light intensity value; and when the light intensity value is smaller than the preset light intensity value, the anti-dazzling function is turned off.

The algorithm unit of the image acquisition and processing module and the algorithm unit of the anti-dazzling function module are shared algorithm units, the algorithm units are integrated in a vehicle-machine controller in the vehicle, and the algorithm units are connected with the two modules (the image acquisition and processing module and the anti-dazzling function module) through a wire harness; the image is acquired through the high-resolution camera, the image is processed frame by frame to respectively calculate the light intensity value, the DMS function data and the OMS function data, and corresponding actions are executed after the calculation is completed.

The transparent lens and the electrochromic lens form a complete inner rearview mirror, and one of the transparent lens and the electrochromic lens is distributed in the area division example diagram of the inner rearview mirror provided by the figure 2; in fig. 2, a transparent area 201 is a distribution area of a transparent lens, the transparent lens is a common transparent glass structure, and a light supplementing lamp and a high-resolution camera are arranged on the back surface of the transparent lens; the rest positions except the transparent lens are all electrochromic lenses (electrochromic areas 202); the camera and the light supplementing lamp are positioned on the back surface of the lens of the inner rearview mirror, so that the privacy is good in the whole view.

The camera can realize high-resolution RGB-IR double-output cameras with a DMS function and an OMS function. The DMS function includes at least the following: monitoring dangerous actions such as fatigue state, line of sight deviation and the like of a driver, making a call and drinking water; the image acquired by the camera is transmitted to the algorithm end for calculation, and aiming at the algorithm detection result, the voice playing equipment is used for carrying out voice reminding or tightening safety belts and other operations, so that the risk of accidents of a driver is reduced. The OMS functions include at least: FACE ID, gesture recognition, carryover detection, short video shots, etc.

That is, the camera of this scheme can also be through judging the size between the light intensity value on the interior rear-view mirror lens and the preset light intensity value and then confirm whether open anti-dazzle function when obtaining high-quality image under RGB and IR mode, realize the further promotion of safe driving and amusement experience in the intelligent cabin system of car.

As can be seen from the above, the main functions of the image acquisition and processing module are: collecting an image and analyzing the image through a camera; in practical application, when a vehicle drives in daytime, a camera collects images of personnel in the vehicle and transmits the collected images to an OMS to trigger corresponding functions (carry-over identification, gesture identification and the like); the camera captures the face image of the driver, and transmits the face image to the DMS to trigger the corresponding function (monitoring the driver status, monitoring whether there is dangerous motion, etc.), whether it is driving in the daytime or at night. When the vehicle is driven at night, strong light of a high beam of a rear vehicle irradiates the inner rearview mirror, the camera collects a light source image and transmits the light source image to the algorithm unit for processing to calculate a light intensity value, the calculated light intensity value is compared with a preset light intensity value, and whether an anti-dazzling function is started or not (namely, whether the electrochromic lens is controlled to change color or not) is determined based on a comparison result. The algorithm unit is integrated in a vehicle-mounted controller in the vehicle and is connected with the image acquisition and processing module and the anti-glare functional module through the main board and the wire harness respectively.

The anti-dazzle function module is mainly used for opening or closing the anti-dazzle function, so that the risk of accidents of the automobile after eyes of a driver are stimulated is reduced. In particular, when driving at night, the high beam of the rear vehicle is easily irradiated onto the inner rear view mirror, thereby causing irritation to eyes of the driver, and because the night environment is dark, when the eyes of the driver are stimulated, the driver is hard to see the road condition ahead, and driving is very dangerous in this case. The anti-dazzling function controlled by the anti-dazzling function module is that a camera is used for collecting light intensity values (light intensity data) on the inner rearview mirror, and when the light intensity values are larger than preset light intensity values, an algorithm unit automatically controls the color of the inner rearview mirror lens to quickly deepen (the anti-dazzling function is started), so that the reflectivity is reduced to weaken the light intensity entering eyes of a driver; when the light intensity value is smaller than the preset light intensity value, the algorithm unit automatically controls the color of the inner rearview mirror to be restored to a normal color state, namely, the anti-dazzling function is closed.

After the anti-dazzle function is started, if the light intensity value collected by the camera is continuously increased, the anti-dazzle grade is automatically improved; and if the light intensity value collected by the camera is reduced, the anti-dazzle grade is automatically reduced until the light intensity value is smaller than the preset light intensity value, and then the anti-dazzle function is closed.

The above is a related explanation about the module division of the interior mirror system.

The size of the transparent area of the lens of the inner rearview mirror can be changed according to the size of the lens of the camera 505 and the size of the light supplementing lamp 506 in the inner rearview mirror, so that the field of view of the image collected by the camera 505 can not contain electrochromic areas, and serious noise is avoided. When the inner rearview mirror housing 502 is covered, the camera 505 and the light compensating lamp 506 have good privacy, and the user experience is enhanced. Electrochromic lens, camera 505 and light filling 506 of inside rear-view mirror lens are connected with mainboard 507 that installs inside the mirror housing 502 intracavity, and mainboard 507 is connected with the car machine controller for provide the power.

In fig. 5, the inner mirror lens is mounted in front of the radiator 503 and the main board 507 and behind the front board 508, so that the inner mirror lens is not blocked.
