The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items. Furthermore, technical features involved in the different embodiments of this application described below may be combined with each other as long as they do not conflict with each other.

[0025] In a first aspect, embodiments of this application provide an electronic rearview mirror device 100, see reference. Figure 1 The electronic rearview mirror device 100 includes: an electronic rearview mirror assembly 10, an image processing assembly 20, and an alarm assembly 30.

[0026] The image processing component 20 includes a serializer unit 21 and an image processing system 22. The image processing system 22 is electrically connected to the first end of the serializer unit 21 and the alarm component 30. The second end of the serializer unit 21 is electrically connected to the electronic rearview mirror component 10.

[0027] The electronic rearview mirror assembly 10 is configured to acquire image data. The electronic rearview mirror assembly 10 refers to the assembly that acquires image data of a target area. It is usually installed on the outside of the vehicle, such as where the rearview mirror is located. The target area can be the area behind the vehicle, the rear-side area, the side area, or any other area that the vehicle's rearview mirror can cover.

[0028] The serializer unit 21 is configured to transmit image data to the image processing system 22. The serializer unit 21 refers to a device that performs serialization processing on image data (such as converting parallel data into serial data) and transmits the processed data to the image processing system 22 through a specific communication line (such as a serial bus).

[0029] Image processing system 22 is configured to process image data and send alarm information to alarm component 30. Image processing system 22 refers to a device that performs image recognition on image data and sends alarm information to alarm component 30 when an anomaly is detected in the target area. Image recognition may include target detection (such as identifying vehicles, pedestrians, obstacles, etc. in an image) and motion analysis of the target object (such as determining the target object's direction of movement, speed, etc.). The specific image recognition process can refer to existing technologies and is not limited here. Image processing system 22 may be a system-on-a-chip (SoC). SoC typically includes a processor, graphics processor, external interfaces, etc. Its specific structure can refer to existing technologies and is not limited here.

[0030] Alarm component 30 is configured to operate based on alarm information. Alarm component 30 refers to a device that operates according to a preset alarm mode upon receiving alarm information. For example, alarm component 30 can be a buzzer; after the image processing system 22 sends alarm information, alarm component 30 emits sound or flashes lights to alert occupants inside the vehicle, reminding them to take timely measures to avoid potential dangers and improve driving safety. In practical applications, alarm component 30 can also be other audible alarms, visual alarms, vibration alarms, and display alarms. For example, a visual alarm can use a light-emitting diode (LED), a vibration alarm can use a vibration motor, and a display alarm can use an LED display, an LCD display, or an OLED display.

[0031] The electronic rearview mirror device 100 of this application embodiment utilizes the existing electronic rearview mirror assembly 10 for image acquisition and alarm, eliminating the need for additional cameras specifically designed for vehicle alarms, thus effectively reducing the hardware cost of the system. Furthermore, the electronic rearview mirror assembly 10 is typically already installed at a reasonable location on the outside of the vehicle, eliminating the need for specialized installation design for additional cameras. The image data acquired by the electronic rearview mirror assembly 10 is directly processed and analyzed, greatly simplifying the installation process, reducing the difficulty and complexity of installation, and minimizing installation time and labor costs.

[0032] In some of these embodiments, see Figure 2 The alarm component 30 includes an in-vehicle networking unit 31. The in-vehicle networking unit 31 is electrically connected to the image processing system 22. The in-vehicle networking unit 31 is configured to upload alarm information to a cloud device.

[0033] The vehicle networking unit 31 refers to a networked device installed inside the vehicle, which enables communication and data exchange between the vehicle and cloud devices outside the vehicle via wireless means. The cloud device can be a mobile terminal or a cloud server.

[0034] In this embodiment, alarm information is automatically uploaded via the vehicle networking unit 31 without manual intervention, avoiding situations where the driver might delay alarming due to distraction or tension in an emergency, ensuring that alarm information can be quickly transmitted to relevant devices. Furthermore, utilizing wireless communication technology, the vehicle networking unit 31 can upload alarm information to cloud devices in real time, ensuring the immediacy and accuracy of the information, which facilitates rapid response and processing.

[0035] In some embodiments, the vehicle networking unit 31 includes a T-BOX. The T-BOX is electrically connected to the image processing system 22.

[0036] T-BOX is an in-vehicle communication terminal device, also known as a remote information processing control unit. It connects the vehicle to cloud devices through wireless communication technologies (such as 4G / 5G) to enable real-time data interaction between the vehicle and cloud devices.

[0037] Specifically, when a vehicle is driving on the road, if there is an accident involving a vehicle, the electronic rearview mirror component 10 will send image data containing information about the accident vehicle to the image processing system 22. The image processing system 22 will perform image recognition on the image data to identify the license plate of the accident vehicle. It can also obtain the current accident location through the GPS module. Then, the image processing system 22 will send the accident vehicle information, such as the license plate of the accident vehicle and the current accident location, as alarm information to the T-BOX. The T-BOX will then send the alarm information to a cloud device, such as the cloud server in the traffic police backend.

[0038] Compared to relying on the vehicle owner or others to call the police while driving, this embodiment eliminates the need for manual reporting, avoiding the safety hazards caused by driver distraction during reporting and improving driving safety. Furthermore, compared to the potential for inaccurate or incomplete reporting information in manual reporting methods, this embodiment utilizes image recognition to analyze accident vehicle information, providing accurate accident locations and scene photos for traffic police analysis and judgment, thus achieving an automated and intelligent reporting process. The specific method by which the image processing system 22 identifies accident vehicle information from image data can refer to existing technologies and is not limited here.

[0039] In this embodiment, the alarm information is uploaded to the cloud device using a T-BOX, which enables automated and real-time transmission of alarm information. Compared with the traditional manual alarm method, this embodiment does not require manual intervention, improving the accuracy and efficiency of alarms and reducing human error and delays.

[0040] In some of these embodiments, see Figure 3 The alarm component 30 includes a door lock unit 32. The door lock unit 32 is electrically connected to the image processing system 22; the door lock unit 32 is configured to operate based on alarm information to control whether the vehicle door is unlocked.

[0041] Door lock unit 32 refers to a device that controls the unlocking and locking of a vehicle door. When the door lock unit 32 controls the door to unlock, the door can be opened; when the door lock unit 32 controls the door to lock, the door cannot be opened. Door lock unit 32 may include a microcontroller or other suitable devices in the prior art.

[0042] Specifically, the alarm information includes a first control signal and a second control signal. After the vehicle stops, the electronic rearview mirror assembly 10 sends image data to the image processing system 22. The image processing system 22 performs image recognition on the image data to identify whether there are other vehicles, pedestrians, or other target objects approaching the door. If so, it sends the first control signal to the door lock unit 32, which then locks the door. If not, it sends the second control signal to the door lock unit 32, which then unlocks the door. This ensures that the vehicle occupants can only open the door when the road conditions are safe, thus achieving vehicle door opening warning and protection.

[0043] In this embodiment, image data from the electronic rearview mirror assembly 10 can be used for image recognition to determine whether the car door is unlocked, thereby reducing the risk of the car door being opened accidentally due to human negligence or misjudgment and improving passenger safety.

[0044] In some of these embodiments, see Figure 4 The electronic rearview mirror assembly 10 includes a first electronic rearview mirror module 11 and a second electronic rearview mirror module 12. The serializer unit 21 includes a first serializer 211 and a second serializer 212.

The second electronic rearview mirror module 12 is electrically connected to a first terminal of the second serializer 212, and the second terminal of the second serializer 212 is electrically connected to the image processing system 22.

[0045] The first electronic rearview mirror module 11 is configured to acquire first sub-image data of a first target sub-region. The first electronic rearview mirror module 11 is typically installed on the first side of the vehicle, such as the left side of the vehicle, and the first target sub-region may be the area behind the first side of the vehicle, such as the area behind the left side of the vehicle.

[0046] The first serializer 211 is configured to transmit the first sub-image data to the image processing system 22. The first serializer 211 refers to a device that performs serialization processing on the first sub-image data (such as converting parallel data into serial data) and transmits the processed data to the image processing system 22 through a specific communication line (such as a serial bus).

[0047] The second electronic rearview mirror module 12 is configured to acquire second sub-image data of a second target sub-region. The second electronic rearview mirror module 12 is typically installed on the second side of the vehicle, such as the right side of the vehicle, and the second target sub-region can be the area behind the second side of the vehicle, such as the area behind the right side of the vehicle.

The second serializer 212 refers to a device that performs serialization processing on the second sub-image data (such as converting parallel data into serial data) and transmits the processed data to the image processing system 22 through a specific communication line (such as a serial bus).

[0049] In this embodiment, dual electronic rearview mirror modules cover the left and right rearward views respectively, and the image processing system can perform image processing and alarm based on the image data from both sides, thereby improving driving safety.

[0050] In some of these embodiments, see Figure 5 The first electronic rearview mirror module 11 includes a first camera 111. The first camera 111 is electrically connected to the first end of the first serializer 211.

[0051] The first camera 111 refers to an image acquisition module used to capture the first target sub-region to obtain the first sub-image data. It is usually installed on the first side of a vehicle, such as the left rearview mirror. It includes devices such as a CCD sensor or a CMOS sensor to acquire the first sub-image data and send the first sub-image data to the image processing system 22 through the first serializer 211. The first sub-image data can be the raw image data acquired by the first camera 111 without any field-of-view cropping or digital zoom and other image processing operations, that is, the original complete image within the maximum field of view directly acquired by the sensor of the first camera 111.

[0052] In this embodiment, the image processing system 22 can acquire the first sub-image data through the first camera 111.

[0053] In some of these embodiments, see Figure 6 The first electronic rearview mirror module 11 also includes a first display screen 112. The first camera 111 is electrically connected to the first display screen 112.

[0054] The first display screen 112 may employ one of the following display devices: LCD, OLED, LCOS, Mini-LED, Mini-OLED, Micro-OLED, and Micro-LED. After receiving the first sub-image data, the first display screen 112 may perform processing such as cropping, correction (e.g., correcting camera distortion), and enhancement (e.g., improving image contrast and brightness) on the first sub-image data, and then display the processed first sub-image data.

[0055] In this embodiment, the driver can observe the first sub-image data or the processed first sub-image data in real time through the first display screen 112, which helps the driver better understand the surrounding environment of the vehicle and improve driving safety.

[0056] In some embodiments, the second electronic rearview mirror module 12 includes a second camera 121. The second camera 121 is electrically connected to a first end of the second serializer 212.

[0057] The second camera 121 refers to an image acquisition module used to capture a second target sub-region to obtain second sub-image data. It is typically installed on the second side of a vehicle, such as the right-side rearview mirror. It includes devices such as a CCD sensor or a CMOS sensor to acquire the second sub-image data and transmit it to the image processing system 22 via the second serializer 212. The second sub-image data can be the raw image data acquired by the second camera 121 without any field-of-view cropping or digital zoom and other image processing operations, that is, the original complete image within the maximum field of view directly captured by the sensor of the second camera 121.

[0058] In this embodiment, the image processing system 22 can acquire second sub-image data through the second camera 121.
