[0002] At present, most vehicles are equipped with traditional optical rearview mirrors, which bring a very poor experience to drivers, especially at night and in rainy and foggy weather. It is difficult to clearly observe the surrounding environment of the vehicle through traditional optical rearview mirrors. The application of electronic rearview mirrors solves the problem of observing the surrounding environment of the vehicle under the current harsh environmental conditions.

[0063] See also Figure 1 , an embodiment of the present application proposes an enhanced display method for an electronic rearview mirror, and the enhanced display method for an electronic rearview mirror is applied to an electronic rearview mirror. The electronic rearview mirror includes an image acquisition device, a display screen, a regional brightness sensor, and a light-transmitting mirror glass. The image acquisition device can be specifically a camera. The display screen, the regional brightness sensor, and the light-transmitting mirror glass are arranged in sequence from the inside to the outside. Specifically, the light-transmitting mirror glass is located at the outermost side, the regional brightness sensor is located in the middle, and the display screen is located at the innermost side. The light-transmitting mirror glass can transmit light. The regional brightness sensor is arranged on the inner side of the light-transmitting mirror glass, and can detect the light intensity of the light reaching the light-transmitting mirror glass. The display screen can display the monitoring video collected by the image acquisition device. The display screen has a partition display function, that is, the display screen can only display the picture in a partial area. The method includes the following steps: S1-S4.

[0064] S1, collecting light intensity data of light irradiated onto the light-transmitting mirror glass through the regional brightness sensor.

[0065] In a specific implementation, a plurality of sampling points may be specifically set in the regional brightness sensor to collect light intensity values ​​at a plurality of positions on the light-permeable mirror glass. The light distribution of the light-permeable mirror glass can be evaluated by the light intensity values ​​at a plurality of positions on the light-permeable mirror glass, and then the dark area and the bright area in the light-permeable mirror glass can be determined. The light intensity value on the dark area is less than a preset first light intensity threshold.

[0066] In one embodiment, the light-transmitting mirror glass is divided into a plurality of first preset areas, for example, the plurality of first preset areas are specifically divided into a middle area, an upper area, a lower area, a left area, and a right area. Among them, the middle area is used to observe the situation in the middle position of the rear side of the vehicle, the upper area is used to observe the situation far behind the rear side of the vehicle, and the lower area is used to observe the situation at the lower position of the rear side of the vehicle. For the left electronic rearview mirror, the left area is used to observe the situation far away from the rear side of the vehicle, and the right area is used to observe the situation close to the rear side of the vehicle. For the right electronic rearview mirror, the left area is used to observe the situation close to the rear side of the vehicle, and the right area is used to observe the situation far away from the rear side of the vehicle. It can be understood that the above division is only based on the field of view, and will not damage the light-transmitting mirror glass, and the light-transmitting mirror glass is still a complete piece of glass.

[0067] Further, in the present embodiment, collecting the light intensity data of the light irradiated on the light-transmitting mirror glass through the regional brightness sensor includes: collecting the light intensity value of the light irradiated on each of the first preset areas of the light-transmitting mirror glass through the regional brightness sensor respectively to obtain the light intensity data.

[0068] In a specific embodiment, the regional brightness sensor is provided with at least one sampling point in each of the first preset areas. If the first preset area is provided with only one sampling point, the light intensity value collected at the sampling point is the light intensity value of the light in the first preset area. If the first preset area is provided with only multiple sampling points, the average value of the light intensity values ​​collected at the multiple sampling points in the first preset area is the light intensity value of the light in the first preset area.

[0069] S2, judging whether there is a dark area in the light-transmissive mirror glass based on the light intensity data, wherein the light intensity value in the dark area is less than a preset first light intensity threshold.

[0070] In a specific implementation, a plurality of sampling points may be specifically set in the regional brightness sensor to collect light intensity values ​​at a plurality of positions on the light-permeable mirror glass. Based on the light intensity values ​​at the plurality of positions, it is determined whether the light-permeable mirror glass has a dark area. For example, sampling points whose light intensity values ​​are less than a first light intensity threshold are selected as target sampling points, and a preset area around each target sampling point (e.g., a circular area or a square area centered on the target sampling point) is a dark area.

[0071] Alternatively, in one embodiment, the light-transmissive mirror glass is divided into a plurality of first preset areas, for example, the plurality of first preset areas are specifically divided into a middle area, an upper area, a lower area, a left area, and a right area. The regional brightness sensor is provided with at least one sampling point in each of the first preset areas. If the first preset area is only configured with one sampling point, the light intensity value collected at the sampling point is the light intensity value of the light in the first preset area. If the first preset area is only configured with multiple sampling points, the average value of the light intensity values ​​collected at the multiple sampling points in the first preset area is the light intensity value of the light in the first preset area.

[0072] The above step of “determining whether the light-transmissive mirror glass has a dark area based on the light intensity data” specifically includes the following steps:

[0073] S21, determining whether the light-transmissive mirror glass has a first preset area where the light intensity value is less than a preset first light intensity threshold.

[0074] In a specific implementation, after determining the light intensity value of each first preset area, it is determined whether the light-transmissive mirror glass has a first preset area with a light intensity value less than a preset first light intensity threshold.

[0075] S22: If the light-transmissive mirror glass has a first preset area whose light intensity value is less than a preset first light intensity threshold, determine the first preset area whose light intensity value is less than the preset first light intensity threshold as the dark area.

[0076] In a specific implementation, if there is a first preset area in the light-transmitting mirror glass where the light intensity value is less than a preset first light intensity threshold, it means that the first preset area is dark and the user cannot clearly observe the situation there. At this time, the first preset area where the light intensity value is less than the preset first light intensity threshold is determined as the dark area.

[0077] S23: If the light-permeable mirror glass does not have a first preset area whose light intensity value is less than a preset first light intensity threshold, it is determined that there is no dark area in the light-permeable mirror glass.

[0078] In a specific implementation, if the light-permeable mirror glass does not have a first preset area with a light intensity value less than a preset first light intensity threshold, it means that all parts of the light-permeable mirror glass are relatively bright, and it is determined that there is no dark area in the light-permeable mirror glass.

[0079] S3: If there is a dark area in the light-transmissive mirror glass, determine a first target area corresponding to the dark area in the display screen.

[0080] In a specific implementation, the display screen is located on the inner side of the light-transmissive mirror glass, and they are aligned. The first target area corresponding to the dark area in the display screen is located directly below the dark area, and has the same area as the dark area. The field of view of the video image displayed in the first target area is the same as the field of view of the dark area, so that the dark area can be displayed enhanced so that the user can observe clearly.

[0081] In one embodiment, the display screen is divided into multiple second preset areas, and the multiple second preset areas correspond one-to-one to the multiple first preset areas; the second preset areas are located at the lower side of the corresponding first preset areas, and the area is the same as the corresponding first preset areas.

[0082] Specifically, the number of the second preset areas is the same as the number of the first preset areas, one first preset area corresponds to one second preset area, and the corresponding first preset areas and second preset areas have the same size and position.

[0083] In this embodiment, the above step of "determining the first target area corresponding to the dark area in the display screen" includes: determining the second preset area corresponding to the dark area as the first target area. Specifically, through the above steps S21-S23, it can be determined that the dark area must be the first preset area, and therefore, in the display screen, the second preset area corresponding to the dark area is determined as the first target area.

[0084] S4, displaying a first monitoring video acquired by the image acquisition device in the first target area, wherein a field of view of the first monitoring video is consistent with a field of view of the dark area.

[0085] In a specific implementation, first, by calibrating the image acquisition device (adjusting the focal length and angle, etc.), the field of view of the video image acquired by the image acquisition device is exactly the same as the field of view of the light-transmitting mirror glass. Then, the video image acquired by the image acquisition device is divided into a plurality of sub-images, and the plurality of sub-images correspond to the plurality of second preset areas of the display screen one by one, and the plurality of sub-images are respectively displayed by the plurality of second preset areas. It can be understood that the field of view of the sub-image displayed in the second preset area is exactly the same as the field of view of the first preset area corresponding to the second preset area.

[0086] In one embodiment, through the above steps S21-S23, it can be determined that the dark area must be the first preset area, and accordingly, the first target area is a second preset area. At this time, the sub-screen corresponding to the first target area is obtained as the first monitoring video, and its corresponding sub-screen is displayed in the first target area. The field of view of the sub-screen is exactly the same as the field of view of the dark area. Therefore, the display enhancement effect of the dark area can be achieved, so that the user can observe accurately.

[0087] Furthermore, in the embodiment of the present application, if there is no dark area in the light-transmitting mirror glass, the display screen is kept in a closed state, thereby being able to better save energy and improve the vehicle's endurance.

[0088] At the same time, if the display screen is damaged, the user can normally observe the situation outside the vehicle through the light-transmitting mirror glass, thereby ensuring safety.

[0089] An enhanced display method for an electronic rearview mirror proposed in an embodiment of the present application is applied to an electronic rearview mirror, wherein the electronic rearview mirror includes an image acquisition device, a display screen, a regional brightness sensor, and a light-permeable mirror glass arranged in sequence from the inside to the outside, and the method includes: acquiring light intensity data of light irradiated on the light-permeable mirror glass by the regional brightness sensor; judging whether there is a dark area on the light-permeable mirror glass based on the light intensity data, wherein the light intensity value on the dark area is less than a preset first light intensity threshold; if there is a dark area on the light-permeable mirror glass, determining a first target area corresponding to the dark area in the display screen; and displaying a first monitoring video acquired by the image acquisition device in the first target area, wherein the field of view of the first monitoring video is consistent with the field of view of the dark area. By arranging the display screen on the inner side of the translucent mirror glass, it conforms to the user's driving habits, is convenient for the user to observe, and does not occupy the space inside the vehicle cockpit; further, when there is a dark area on the translucent mirror glass, the first monitoring video collected by the image acquisition device is displayed in the corresponding first target area in the display screen, and the field of view of the first monitoring video is consistent with the field of view of the dark area, thereby achieving the effect of display enhancement for the dark area, so that the user can observe accurately; at the same time, when there is no dark area, the display screen is turned off, and the user observes through the translucent mirror glass, thereby greatly saving energy and improving vehicle endurance.

[0090] Further, see Figure 2 In some specific driving scenarios, in order to improve the accuracy of the user's observation of the rear, the method further includes the following steps: S21-S26.

[0091] S21, determining whether the vehicle is in a preset target driving state.

[0092] It is understandable that the target driving state can be set by a person skilled in the art, and this application does not specifically limit this. For example, the target driving state includes a high-speed driving state, a low-speed driving state, a turning state, and a reversing state.

[0093] In the target driving state, the tolerance for clear vision is lower. Therefore, the brightness requirement for the associated area corresponding to the target driving state is higher. If the brightness does not meet the requirement, the display is enhanced through the display screen so that the user can observe clearly.

[0094] In one embodiment, the above step of “determining whether the vehicle is in a preset target driving state” includes the following steps:

[0095] S211, determining whether the vehicle speed is greater than a preset first speed threshold.

[0096] In a specific implementation, it is determined whether the vehicle speed is greater than a preset first speed threshold. The first speed threshold can be set by a person skilled in the art, such as 80 km / h; this application does not specifically limit this.

[0097] S212: If the vehicle speed is greater than a preset first speed threshold, it is determined that the vehicle is in a high-speed driving state.

[0098] In a specific implementation, if the vehicle speed is greater than a preset first speed threshold, it means that the vehicle speed is relatively fast at this time, and it is determined that the vehicle is in a high-speed driving state.

[0099] S213, determining whether the vehicle speed is less than a preset second speed threshold.

[0100] In a specific implementation, it is determined whether the vehicle speed is less than a preset second speed threshold. The second speed threshold can be set by a person skilled in the art, for example, 30 km / h; this application does not specifically limit this.

[0101] S214: If the vehicle speed is less than a preset second speed threshold, it is determined that the vehicle is in a low-speed driving state.

[0102] In a specific implementation, if the vehicle speed is less than a preset second speed threshold, it means that the vehicle speed is relatively slow at this time, and it is determined that the vehicle is in a low-speed driving state.

[0103] S215, determining whether a detection signal from a steering angle sensor is received.

[0104] In a specific implementation, it is determined whether a detection signal of a direction angle sensor is received. The direction angle sensor is used to detect whether the vehicle is turning. If the vehicle is turning, the direction angle sensor sends a detection signal.

[0105] S216: If a detection signal from the direction angle sensor is received, it is determined that the vehicle is in a turning state.

[0106] In a specific implementation, if a detection signal from the direction angle sensor is received, it means that the vehicle is turning, and it is determined that the vehicle is in a turning state.

[0107] S217, determining whether a detection signal of the reverse gear position of the vehicle is received.

[0108] In a specific implementation, the gear position information of the gear position sensor of the vehicle is detected to determine whether a detection signal indicating that the vehicle is in reverse gear is received.

[0109] S218: If a detection signal of the reverse gear position of the vehicle is received, it is determined that the vehicle is in a reverse state.

[0110] In a specific implementation, if a detection signal of the reverse gear position of the vehicle is received, it means that the vehicle is in a reverse state.

[0111] S22: If the vehicle is in a preset target driving state, obtain a light intensity value of an associated area of ​​the light-permeable mirror glass corresponding to the target driving state based on the light intensity data.

[0112] In a specific implementation, each target driving state corresponds to an associated area. For example, in one embodiment, the light-transmissive mirror glass is divided into a plurality of first preset areas, such as a plurality of first preset areas specifically divided into a middle area, an upper area, a lower area, a left area, and a right area. The associated area may specifically be a first preset area.

[0113] Specifically, for a high-speed driving state, the user is concerned about the distant field of vision, so the associated area corresponding to the high-speed driving state is the upper area of ​​the light-transmitting mirror glass.

[0114] For the low-speed driving state, the user is concerned about the near field of vision, so the associated area corresponding to the low-speed driving state is the lower area of ​​the light-transmitting mirror glass.

[0115] For the turning state, it is used to care about the field of vision around the vehicle. Therefore, for the right rearview mirror, the associated area corresponding to the turning state is the left area; for the left rearview mirror, the associated area corresponding to the turning state is the right area;

[0116] For the reversing state, the vehicle's surrounding field of vision is taken into consideration. Therefore, for the right rearview mirror, the associated area corresponding to the turning state is the left area; for the left rearview mirror, the associated area corresponding to the turning state is the right area.

[0117] At the same time, when reversing, the electronic rearview mirror can be controlled to flip down to a preset angle to better observe the situation near the vehicle body.

[0118] For the light intensity value of the associated area, the collection method is as follows: the regional brightness sensor sets at least one sampling point in each of the first preset areas. If the first preset area is only configured with one sampling point, the light intensity value collected at the sampling point is the light intensity value of the light in the first preset area. If the first preset area is only configured with multiple sampling points, the average value of the light intensity values ​​collected at the multiple sampling points in the first preset area is the light intensity value of the light in the first preset area.

[0119] S23, determining whether the light intensity value of the associated area is less than a preset second light intensity threshold, wherein the second light intensity threshold is greater than the first light intensity threshold.

[0120] In a specific implementation, when the vehicle is in the target driving state, the user needs to view the situation of the associated area more clearly, and the user has higher requirements for the brightness of the associated area and lower tolerance. Therefore, it is determined whether the light intensity value of the associated area is less than a preset second light intensity threshold, wherein the second light intensity threshold is greater than the first light intensity threshold. It can be understood that the first light intensity threshold and the second light intensity threshold are both set by those skilled in the art and are not specifically limited in this application.

[0121] S24: If the light intensity value of the associated area is less than a preset second light intensity threshold, determine whether the associated area is determined to be a dark area.

[0122] In a specific implementation, if the light intensity value of the associated area is less than the preset second light intensity threshold, it means that in the target driving state, the brightness of the associated area is low and cannot be observed by the user. At this time, it is determined whether the associated area is determined to be a dark area.

[0123] S25: If the associated area is not determined to be a dark area, determine a second target area corresponding to the associated area in the display screen.

[0124] In a specific implementation, if the associated area is determined to be a dark area, it means that the second target area corresponding to the associated area has been lit up to display the surveillance video, that is, the field of view enhancement action for the associated area has been completed.

[0125] If the associated area is not determined to be a dark area, it means that the second target area corresponding to the associated area is not illuminated at this time, and the user cannot accurately observe the situation of the associated area.

[0126] In the present application, when the associated area is not determined to be a dark area, a second target area corresponding to the associated area is determined in the display screen. Specifically, as described above, the associated area can be specifically a first preset area, and then in the display screen, a second preset area corresponding to the associated area is obtained as the second target area.

[0127] S26, displaying a second monitoring video acquired by the image acquisition device in the second target area, wherein a field of view of the second monitoring video is consistent with a field of view of the associated area.

[0128] In a specific implementation, first, the image acquisition device is calibrated so that the field of view of the video image acquired by the image acquisition device is exactly the same as that of the electronic rearview mirror. Then, the video image acquired by the image acquisition device is divided into a plurality of sub-images, and the plurality of sub-images correspond to the plurality of second preset areas of the display screen one by one, and the plurality of sub-images are displayed by the plurality of second preset areas respectively.

[0129] In the present application, the second target area can be specifically a second preset area. Therefore, a sub-screen corresponding to the second target area is obtained as the second monitoring video, and its corresponding sub-screen is displayed in the second target area. The field of view of the sub-screen is exactly the same as the field of view of the associated area. Therefore, it can achieve the effect of display enhancement for the associated area, so that the user can observe accurately.

[0130] In one embodiment, see Figure 3 In some abnormal situations, the user has higher requirements for the clarity of the observation field of view. In order to meet the user's observation needs in abnormal situations, the method also includes the following steps S31-S32.

[0131] S31, determining whether a preset abnormal situation is detected outside the vehicle.

[0132] In a specific implementation, it is determined whether an abnormal situation is detected outside the vehicle. The abnormal situation may be rain or fog and the situation where there is an obstacle outside the vehicle. The abnormal situation may be set by a person skilled in the art, and this application does not specifically limit this. For rain or fog, it may be detected by a corresponding rain or fog sensor, and for obstacles, it may be detected by the monitoring video of the image acquisition device.

[0133] S32, if a preset abnormal situation is detected outside the vehicle, a third monitoring video captured by the image acquisition device is displayed on the complete display area of ​​the display screen, wherein the field of view of the third monitoring video is consistent with the field of view of the light-transmitting mirror glass.

[0134] In a specific implementation, if a preset abnormal situation is detected outside the vehicle, in order to facilitate the user to clearly observe the situation outside the vehicle, the third monitoring video collected by the image acquisition device is displayed on the complete display area of ​​the display screen, and at this time, the entire area of ​​the display screen is lit. Among them, the field of view of the third monitoring video is consistent with the field of view of the light-transmitting mirror glass. Specifically, the image acquisition device is calibrated in advance (adjusting the focal length and angle, etc.) so that the field of view of the video picture collected by the image acquisition device is exactly the same as the field of view of the light-transmitting mirror glass.

[0135] Further, see Figure 4 In view of the situation where there are moving objects around the vehicle, in order to facilitate the user to better observe the target object, the method also includes the following steps S41-S43.

[0136] S41, determining whether a target moving object is detected in a preset detection area around the vehicle.

[0137] In a specific implementation, the light-transmissive mirror glass is divided into a plurality of first preset areas, for example, the plurality of first preset areas are specifically divided into a middle area, an upper area, a lower area, a left area, and a right area. For the electronic rearview mirror located on the left, the preset detection area around the vehicle corresponds to the right area. For the electronic rearview mirror located on the right, the preset detection area around the vehicle corresponds to the left area.

[0138] In the sub-image corresponding to the detection area, it is detected whether there is a target moving object (for example, detection is performed through a preset target detection algorithm, which is not specifically limited in the present application), and the target moving object may specifically include pedestrians and vehicles.

[0139] S42, if a target moving object is detected in a preset detection area around the vehicle, a third target area corresponding to the detection area is determined in the display screen, and a fourth monitoring video captured by the image acquisition device is displayed in the third target area, wherein the field of view of the fourth monitoring video corresponds to the detection area. That is, the field of view of the fourth monitoring video at least includes the detection area.

[0140] In a specific implementation, if a target moving object is detected in a preset detection area around the vehicle, a third target area corresponding to the detection area is determined in the display screen. As described above, the detection area can be specifically a left area or a right area, and therefore, a second preset area corresponding to the left area or the right area is determined in the display screen as the third target area. A sub-screen corresponding to the third target area is obtained as the fourth monitoring video, and its corresponding sub-screen is displayed in the third target area. The field of view of the sub-screen can include the detection area, so that the user can clearly observe the situation in the detection area.

[0141] S43: Mark the target moving object and the trajectory of the target moving object in the fourth monitoring video.

[0142] In a specific implementation, first, the position of the target moving object in multiple consecutive frames is determined (for example, through detection by a preset target detection algorithm, which is not specifically limited in this application), thereby determining the trajectory of the target moving object, and highlighting the target moving object and its trajectory, so that the user can accurately observe the target moving object.
