Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0027] According to an embodiment of the present invention, a projection method for a vehicle rearview mirror is provided. It should be noted that in the flowcharts in the accompanying drawings, the steps shown therein can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0028] The following describes a projection method for a vehicle rearview mirror according to an embodiment of the present invention.

[0029] Figure 1 : is a flow chart of a projection method for a vehicle rearview mirror according to an embodiment of the present invention, such as Figure 1 As shown, the method may include the following steps:

[0030] Step S101: Acquire an original image corresponding to the vehicle.

[0031] In the technical solution provided in step S101 of the present invention, an original image of the vehicle is obtained, wherein the original image is obtained by capturing a mapped image of a rearview mirror in the vehicle using an image capture device on the vehicle. The image capture device may be a high-definition camera mounted on the exterior of the vehicle, which may be simply referred to as a camera.

[0032] Optionally, the image acquisition device in the camera subsystem is used to capture real-time video of the vehicle; based on the real-time video of the vehicle, the original image of the vehicle is determined, for example, a high-definition camera is used to capture real-time video from the rear or side of the vehicle, and the real-time video is processed to obtain the original image.

[0033] It should be noted that this is only a preferred implementation for obtaining the original image corresponding to the vehicle, and does not specifically limit the process and method of obtaining the original image corresponding to the vehicle.

[0034] Step S102: performing image processing on the original image to obtain a target image of the vehicle.

[0035] In the technical solution provided in step S102 of the present invention, after obtaining the original image, the image processing subsystem is required to receive the original image from the camera subsystem and perform image processing on the original image using an image processing algorithm to obtain a target image of the vehicle, wherein the clarity of the target image is higher than that of the original image. The image processing algorithm may be an image enhancement algorithm or a distortion correction algorithm. It should be noted that the image processing algorithm is merely illustrative and is not specifically limited to this algorithm.

[0036] For example, after the image processing subsystem receives the original image from the camera subsystem, it needs to perform image enhancement, distortion correction, or dynamic range adjustment on the original image to obtain the target image, thereby ensuring that the target image can be projected clearly and accurately.

[0037] It can be understood that this is only a preferred implementation method for obtaining the target image of the vehicle, and the process and method of obtaining the target image of the vehicle are not specifically limited. As long as the original image is processed, the process and method of obtaining the target image of the vehicle are within the scope of protection of the present invention and will not be repeated here.

[0038] Step S103 : Projecting the target image onto a transparent medium of the vehicle using the optical elements of the vehicle to obtain a projection result of the target image.

[0039] In the technical solution provided in the above step S103 of the present invention, after obtaining the target image, the optical elements of the vehicle in the optical projection subsystem are used to project the target image onto the transparent medium of the vehicle to obtain a projection result so that vehicle information can be displayed on the transparent medium.

[0040] Optionally, the projection result is used to represent vehicle information when the vehicle is in a normal driving state. The transparent medium can be called a display medium, such as the original side window of the vehicle, or a specially designed transparent display screen.

[0041] For example, the target image can be projected onto the side windows of the vehicle using the vehicle's optical elements, allowing the driver to obtain vehicle information in a timely manner and quickly understand the vehicle's driving status.

[0042] It should be noted that this is only a preferred implementation method for obtaining the projection result of the target image, and does not specifically limit the process and method of obtaining the projection result of the target image. As long as the optical elements of the vehicle are used to project the target image onto the transparent medium of the vehicle, the process and method of obtaining the projection result of the target image are within the scope of protection of the present invention and are not listed here.

[0043] In the above steps S101 to S103 of the present invention, an original image corresponding to the vehicle is obtained, wherein the original image is obtained by capturing a mapping image of a rearview mirror in the vehicle through an image acquisition device on the vehicle; image processing is performed on the original image to obtain a target image of the vehicle, wherein the clarity of the target image is higher than the clarity of the original image; and the target image is projected onto a transparent medium of the vehicle using an optical element of the vehicle to obtain a projection result of the target image, wherein the projection result is used to represent vehicle information when the vehicle is in a normal driving state. That is to say, the embodiment of the present invention can capture the mapping image of the rearview mirror in the vehicle through the image capture device on the vehicle to obtain the original image of the vehicle, and then perform image processing on the original image to obtain the target image of the vehicle. At this time, the optical elements of the vehicle can be used to project the target image obtained above onto the transparent medium of the vehicle to obtain the projection result of the target image. Considering that after the original image is obtained and the original image is processed to obtain the target image of the vehicle, the optical elements can be used to realize the projection of the target image, so that the target image can be displayed on the transparent medium, so that the driver can quickly understand the vehicle information of the vehicle in a normal driving state, thereby solving the technical problem of high manufacturing and maintenance costs of the electronic exterior rearview mirror of the vehicle, and achieving the technical effect of reducing the manufacturing and maintenance costs of the electronic exterior rearview mirror of the vehicle.

[0044] The above method of this embodiment is further introduced below.

[0045] As an optional embodiment, the image acquisition device includes at least: a first image acquisition device and a second image acquisition device, wherein the first image acquisition device is deployed at the rear of the vehicle, and the second image acquisition device is deployed at the side and rear of the vehicle.

[0046] In this embodiment, the image acquisition device in the camera subsystem includes at least: a first image acquisition device and a second image acquisition device, wherein the first image acquisition device can be called a first camera and the second image acquisition device can be called a second camera, that is, the first camera can be deployed at the rear of the vehicle and the second camera can be deployed at the side and rear of the vehicle, and both the first camera and the second camera are provided with waterproof and dustproof functions and can work normally under different lighting conditions.

[0047] For example, the camera subsystem includes at least two cameras, and the high-definition camera installed on the outside of the vehicle is responsible for capturing real-time video images from the rear and sides of the vehicle in order to obtain original images. These cameras need to be waterproof and dustproof and able to work under different lighting conditions.

[0048] As an optional embodiment, the optical element includes at least: a first element, a second element, a third element and a fourth element, wherein the first element is used to improve the clarity of the target image during the projection process, the second element is used to reduce the interference information of the target image during the projection process, the third element is used to modulate the target image, and the fourth element is used to image the target image.

[0049] In this embodiment, the optical elements of the optical projection subsystem include at least: a first element, a second element, a third element and a fourth element, wherein the first element can be a collimating lens, which is used to convert the video image captured by the camera into a parallel light beam, and this parallel light beam helps to maintain the clarity and focus of the image, especially when projecting onto a farther transparent medium (such as a vehicle side window).

[0050] Optionally, the second element can be a polarization beam splitter, which can split polarized light into two directions, and is used to guide the image light beam reflected by the liquid crystal on silicon (LCOS) chip to the imaging lens, while reducing unnecessary light scattering and interference, improving the contrast and clarity of the image, and ensuring high-quality presentation of the projected image.

[0051] Optionally, the third element can be an LCOS chip, which is used to convert the digital image signal captured by the camera into an optical signal, which can be responsible for processing and modulating the image, and then reflecting the modulated light for further processing and projection by subsequent optical elements (such as collimating lenses and imaging lenses).

[0052] Optionally, the fourth element can be an imaging lens, which focuses and amplifies the optical signal processed by the LCOS chip, ultimately projecting a clear image onto a transparent medium inside the vehicle. The design of the imaging lens must take into account the projection distance, the transparency and reflective properties of the medium, and the required image magnification and clarity.

[0053] As an optional embodiment, before using the vehicle's optical elements to project the target image onto the vehicle's transparent medium to obtain the projection result of the target image, the method also includes: obtaining the transparency of the transparent medium, wherein the transparency is used to characterize the projection clarity of the projected image on the transparent medium; comparing the transparency with a transparency threshold to obtain a comparison result, wherein the comparison result is used to characterize that the transparency is equal to the transparency threshold.

[0054] In this embodiment, the transparency of the transparent medium is obtained, and then the transparency is compared with a transparency threshold to obtain a comparison result, wherein the transparency can be determined by the transmittance, which is used to indicate the percentage of light passing through the material, for example, 100%, and the higher the transmittance, the more transparent the material.

[0055] For example, before projecting the target image onto the display medium of the vehicle, it is necessary to detect the transparency of the display medium so that the transparency of the display medium is equal to the transparency threshold. That is, the display medium needs to have sufficient transparency so that it will not significantly affect the driver's external field of view while displaying the image.

[0056] As an optional embodiment, after using the vehicle's optical elements to project the target image onto the vehicle's transparent medium and obtaining the projection result of the target image, the method also includes: determining the projection image on the transparent medium based on the projection result, and obtaining the demand information of the driving object of the vehicle, wherein the demand information is used to characterize the driving object's adjustment demand for the projection image; determining the adjustment type of the projection image based on the demand information, wherein the adjustment type is used to characterize the display method of the adjusted projection image; generating an adjustment instruction for the projection image based on the adjustment type; and adjusting the projection image in response to the adjustment instruction.

[0057] In this embodiment, after obtaining the projection result, the projection image on the transparent medium can be determined based on the projection result, and the demand information of the driving object of the vehicle can be obtained. Based on the demand information, the adjustment type of the projection image can be determined on the center console of the vehicle, and then based on the adjustment type obtained above, an adjustment instruction of the projection image is generated, so that in response to the adjustment instruction, the projection image can be adjusted using the vehicle's control system.

[0058] Optionally, the driving object may be a driver. Three buttons are provided on the center console, namely a first button, a second button, and a third button, wherein the function of the first button is to adjust the image size, the function of the second button is to adjust the image position, and the function of the third button is to adjust the image brightness.

[0059] Optionally, the control system includes a user interface and software algorithms for adjusting the size, position, and brightness of the projected image, as well as managing other functions of the system, such as initiating night mode or an automatic cleaning mechanism.

[0060] Optionally, the adjustment type includes at least: a first adjustment type, a second adjustment type and a third adjustment type, wherein the first adjustment type is used to adjust the size of the projected image, the second adjustment type is used to adjust the position of the projected image, and the third adjustment type is used to adjust the brightness of the projected image.

[0061] For example, after obtaining the projected image, it is necessary to select the adjustment type on the vehicle's center console according to the driver's needs, and use the vehicle's control system to adjust the size, position or brightness of the projected image, thereby generating an adjustment instruction, and adjusting the projected image according to the adjustment instruction.

[0062] As an optional embodiment, the projected image is adjusted in response to an adjustment instruction, including: obtaining the original operating function of the steering wheel in the vehicle, wherein the original operating function is used to characterize the execution operation of the steering wheel under normal driving conditions of the vehicle; in response to the adjustment instruction, the original operating function is switched to the target operating function of the steering wheel to obtain a switching result; based on the switching result, in response to the target operating function being in the activated state, the projected image is adjusted.

[0063] In this embodiment, the original operating function of the steering wheel in the vehicle is obtained, and according to the adjustment instruction, the original operating function is switched to the target operating function of the steering wheel to obtain a switching result. Then, according to the switching result, when the target operating function is in the activated state, the buttons on the steering wheel are used to adjust the projected image.

[0064] For example, the original operating function of the steering wheel of the vehicle in normal driving state is obtained. According to the obtained adjustment instruction, the original operating function can be switched to the target operating function, that is, the operating function that responds to the adjustment instruction. After the original operating function is successfully switched to the target operating function of the steering wheel, if the target operating function has been started, the projection image can be adjusted through the buttons on the steering wheel.

[0065] In this embodiment of the present invention, a high-definition camera mounted on the vehicle's exterior captures real-time video images of the rear and side areas. An image processing subsystem receives the raw images from the camera and performs the necessary processing to ensure that the images projected onto the vehicle windows or display screens are clear and realistic. Furthermore, a display medium is required, which can be the vehicle's existing side windows or a specially designed transparent display screen. The display medium must be sufficiently transparent to provide images without significantly affecting the driver's external field of view. Furthermore, a control system must be designed, including a user interface and software algorithms for adjusting the size, position, and brightness of the projected image, as well as managing other system functions. Finally, a power management subsystem must be designed, taking into account the system's energy consumption and ensuring that the projection-type electronic exterior rearview mirror does not excessively consume the vehicle's power. This addresses the high manufacturing and maintenance costs of electronic exterior rearview mirrors, achieving the technical effect of reducing the manufacturing and maintenance costs of the vehicle's electronic exterior rearview mirrors.

[0066] In this embodiment, an original image corresponding to the vehicle is obtained, wherein the original image is obtained by capturing a mapping image of a rearview mirror in the vehicle through an image capture device on the vehicle; image processing is performed on the original image to obtain a target image of the vehicle, wherein the clarity of the target image is higher than the clarity of the original image; and the target image is projected onto a transparent medium of the vehicle using an optical element of the vehicle to obtain a projection result of the target image, wherein the projection result is used to represent vehicle information when the vehicle is in a normal driving state. That is to say, the embodiment of the present invention can capture the mapping image of the rearview mirror in the vehicle through the image capture device on the vehicle to obtain the original image of the vehicle, and then perform image processing on the original image to obtain the target image of the vehicle. At this time, the optical elements of the vehicle can be used to project the target image obtained above onto the transparent medium of the vehicle to obtain the projection result of the target image. Considering that after the original image is obtained and the original image is processed to obtain the target image of the vehicle, the optical elements can be used to realize the projection of the target image, so that the target image can be displayed on the transparent medium, so that the driver can quickly understand the vehicle information of the vehicle in a normal driving state, thereby solving the technical problem of high manufacturing and maintenance costs of the electronic exterior rearview mirror of the vehicle, and achieving the technical effect of reducing the manufacturing and maintenance costs of the electronic exterior rearview mirror of the vehicle.

[0067] The technical solutions of the embodiments of the present invention are described below with reference to preferred implementation methods.

[0068] Electronic exterior mirrors are becoming an essential component of future smart car designs. They replace traditional physical mirrors with cameras and displays, providing a wider field of view, clearer images, and better adaptability to varying weather and lighting conditions.

[0069] In related technologies, modern electronic exterior rearview mirrors use high-resolution cameras to capture clear images in all lighting conditions. These cameras typically feature night vision capabilities, as well as anti-glare and rain-proof designs, ensuring a clear view even in inclement weather. Furthermore, the electronic rearview mirror's mapped image can be analyzed in real time by a built-in image processing unit, optimizing image quality to remove interference such as raindrops, snowflakes, or glare. In addition, some systems also feature object detection and distance estimation to help drivers better judge the situation behind them. Unlike traditional rearview mirrors, the image from the electronic rearview mirror is displayed directly on a display screen in the cockpit, usually located where a traditional rearview mirror would be or near the dashboard. This design not only reduces wind resistance but also provides a wider, unobstructed field of view, especially in large vehicles or sport utility vehicles (SUVs).

[0070] In summary, electronic exterior mirrors are rapidly developing. Their improved visibility, enhanced safety, and energy savings make them an integral part of future automotive design. However, vehicles equipped with electronic exterior mirrors require regular maintenance and repair, leading to high manufacturing and maintenance costs.

[0071] Therefore, in order to solve the above problems, the present invention provides a projection method for a vehicle rearview mirror, which includes: obtaining an original image corresponding to the vehicle, wherein the original image is obtained by capturing a mapping image of the rearview mirror in the vehicle through an image acquisition device on the vehicle; performing image processing on the original image to obtain a target image of the vehicle, wherein the clarity of the target image is higher than the clarity of the original image; and utilizing the optical elements of the vehicle to project the target image onto a transparent medium of the vehicle to obtain a projection result of the target image, wherein the projection result is used to represent vehicle information when the vehicle is in a normal driving state. That is to say, the embodiment of the present invention can capture the mapping image of the rearview mirror in the vehicle through the image capture device on the vehicle to obtain the original image of the vehicle, and then perform image processing on the original image to obtain the target image of the vehicle. At this time, the optical elements of the vehicle can be used to project the target image obtained above onto the transparent medium of the vehicle to obtain the projection result of the target image. Considering that after the original image is obtained and the original image is processed to obtain the target image of the vehicle, the optical elements can be used to realize the projection of the target image, so that the target image can be displayed on the transparent medium, so that the driver can quickly understand the vehicle information of the vehicle in a normal driving state, thereby solving the technical problem of high manufacturing and maintenance costs of the electronic exterior rearview mirror of the vehicle, and achieving the technical effect of reducing the manufacturing and maintenance costs of the electronic exterior rearview mirror of the vehicle.

[0072] In an embodiment of the present invention, an electronic exterior rearview mirror with a projection optical display is proposed. The projection optical exterior rearview mirror completely gets rid of the reliance of existing electronic exterior rearview mirror technology on LCD screens. Since it no longer relies on electronic LCD screens to display the information obtained by the electronic rearview mirror, it reduces possible failures caused by LCD screens. On the other hand, it does not require repair and maintenance of the LCD screen, thereby reducing maintenance costs. In addition, users do not need to worry about problems such as blue screens, black screens, and freezes caused by LCD screens, thereby improving safety and stability. Finally, the screen size of the projection optical exterior rearview mirror is much larger than that of the LCD screen exterior rearview mirror, and the size, angle, and position can be adjusted. The user experience is closer to that of a traditional rearview mirror and the user experience is better, allowing users to adapt to the new exterior rearview mirror technology more smoothly.

[0073] In an embodiment of the present invention, the design concept of an optical projection electronic exterior rearview mirror is to use optical components to project real-time video images from the vehicle's exterior onto a transparent medium inside the vehicle, such as a side window or a dedicated transparent display screen, thereby replacing traditional physical rearview mirrors. This design aims to provide a wider field of view, reduce blind spots, and maintain good visibility in all weather conditions. Key design considerations include the projection system's optical performance, image clarity, brightness adjustment, immunity to environmental interference, and system reliability and durability.

[0074] According to an embodiment of the present invention, a projection system for a vehicle rearview mirror is provided. It should be noted that the projection system for a vehicle rearview mirror can be used to execute a projection method for a vehicle rearview mirror in an embodiment.

[0075] Figure 2 FIG. 1 is a schematic diagram of a projection system for a vehicle rearview mirror according to an embodiment of the present invention. Figure 2 As shown, a projection system 200 for a vehicle rearview mirror may include: a camera subsystem 201 , an image processing subsystem 202 and an optical projection subsystem 203 .

[0076] The camera subsystem 201 is used to obtain an original image corresponding to the vehicle, wherein the original image is obtained by collecting the mapping image of the rearview mirror in the vehicle through an image acquisition device on the vehicle.

[0077] Optionally, a high-definition camera can be installed on the outside of the vehicle in the camera subsystem 201. The camera is responsible for capturing real-time video images of the rear and side rear of the vehicle in order to obtain original images. These cameras need to be waterproof and dustproof and be able to work under different lighting conditions.

[0078] The image processing subsystem 202 is configured to perform image processing on the original image to obtain a target image of the vehicle, wherein the clarity of the target image is higher than that of the original image.
