[0079] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0080] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0081] With the development of electronic technology, the requirements for the level of vehicle intelligence are also increasing. Currently, vehicles can use electronic rearview mirrors to replace traditional optical rearview mirrors. Electronic rearview mirrors typically include a camera and a display. Generally, the camera captures images of traffic conditions outside the vehicle and displays these images on the in-vehicle display. Drivers can view the images on the in-vehicle display to understand the traffic conditions outside the vehicle (e.g., behind the vehicle) and react accordingly to ensure driving safety. Compared to traditional optical rearview mirrors, electronic rearview mirrors have advantages such as reduced wind resistance and improved visibility in rainy or foggy weather.

[0082] Please refer to Figure 1, which is a schematic diagram of the display interface of an electronic rearview mirror. Figure 1 shows a comparison between the display interface b11 of the electronic rearview mirror and the original image b1. Since the display in the electronic rearview mirror is usually installed on at least one of the A-pillars and B-pillars, or on the door frame, the installation position limits the size of the display, making it relatively small to avoid affecting the driver's field of vision in the vehicle's cabin. Furthermore, because the camera in the electronic rearview mirror has a large field of view, and the aspect ratio of the original image b1 captured by the camera differs from that of the display interface b11, the original image b1 is usually cropped before being displayed on the screen. That is, the display area of ​​the display interface b11 is small, and not all of the original image b1 captured by the camera is displayed on the display interface b11. However, vehicles may be present in the cropped portion b12 of the original image b1, preventing the driver from noticing approaching vehicles from the display and creating a safety hazard during driving.

[0083] Please refer to Figures 2 and 3. Figure 2 is a schematic diagram of the application environment of a vehicle reminder device 100 provided in an embodiment of this application, and Figure 3 is a structural schematic diagram of a vehicle reminder device 100 provided in an embodiment of this application. The vehicle provided in this embodiment includes a vehicle body 200 and a vehicle reminder device 100, which is fixedly installed on the vehicle body. The vehicle reminder device 100 may include: a processor 110 (not shown in Figure 2), a camera 120, and a first display screen 130. The vehicle body has a driver's cab. The camera 120 is located outside the driver's cab and is configured to capture images of the external environment of the driver's cab. The processor 110 and the first display screen 130 are located inside the driver's cab. The processor 110 is configured to control the first display screen 130 to display at least a portion of the image provided by the camera 120.

[0084] In this embodiment, the vehicle's reminder device 100 may include an electronic rearview mirror for acquiring and displaying images of the vehicle's exterior to the driver. The first display screen 130 may be a display within the electronic rearview mirror, and the camera 120 may be a camera within the electronic rearview mirror. The vehicle may directly use an electronic rearview mirror to replace a traditional optical rearview mirror, or an optical rearview mirror may also be provided; this embodiment does not limit this.

[0085] The processor 110 may include a server or a server cluster. The processor 110 establishes wired or wireless connections with both the first display screen 130 and the camera 120, for example, the processor 110 establishes communication connections with both the first display screen 130 and the camera 120.

[0086] Application scenarios of this application embodiment may include: for vehicles in motion, real-time vehicle detection is performed on the shooting area of ​​camera 120, which can detect target vehicles located at a distance from the vehicle at any time, that is, detect the target vehicle image present in the content that has been cropped in the original image, so that the driver can be aware of the approaching vehicle behind and take appropriate precautions. Alternatively, for vehicles that are in the process of parking, it can promptly remind the driver of the obstacle behind them.

[0087] Please refer to Figure 4, which is a schematic diagram of a display interface a1 of a first display screen according to an embodiment of this application. Figure 4 also shows a comparison between the display interface a1 of the first display screen and an image captured by a camera. The processor in the vehicle reminder device can be used to: receive an original image s1, which can be an image captured by a camera. The original image s1 includes a first region s11 and a second region s12 located outside the first region s11; identify a target vehicle in the original image s1; generate a first reminder message in response to the identification that a target vehicle image exists in the second region s12 of the original image s1; and control the first display screen to display a first display interface, which includes a first display area a11 and a second display area a12. The display content of the first display area a11 is obtained based on the first region s11 of the original image s1, and the second display area a12 is used to display the first reminder message. The display area of ​​the first display area a11 is larger than the display area of ​​the second display area a12.

[0088] The original image s1 is the actual image captured by the camera. The processor can crop the received original image s1. The first region s11 of the original image s1 is the area retained after cropping, and the second region s12 of the original image s1 is the area cropped out after cropping. The actual area corresponding to the first region s11 of the original image s1 is the core area monitored by the vehicle's alert device through the camera. Vehicles located in the core area have a significant impact on the current driving status of the vehicle, and the driver needs to be aware of the vehicle's model, driving status, and other information. The actual area corresponding to the second region s12 of the original image s1 is the surrounding area monitored by the vehicle's alert device through the camera. Vehicles located in the surrounding area have a smaller impact on the current driving status of the vehicle, and the driver only needs to be aware that the vehicle exists in the surrounding area. Therefore, the first region s11 of the original image s1 can be displayed in the first display area a11 of the first display interface of the first display screen. The first display area a11 can be constantly lit, meaning that the image formed after cropping the original image s1 can be displayed on the first display screen in real time.

[0089] The target vehicle image can correspond to a target vehicle. The image of the target vehicle in the original image s1 is the target vehicle image. The target vehicle can include at least one type of vehicle. For example, the target vehicle category is a preset large vehicle, or the target vehicle's driving speed exceeds a preset driving speed, or the target vehicle is any vehicle other than the current vehicle where the vehicle's reminder device is located.

[0090] The camera is used to capture real-time images of the external area of ​​the current vehicle and sends the captured raw image s1 to the processor, enabling the processor to monitor environmental changes in the external area of ​​the vehicle in real time. By performing target vehicle identification on the raw image s1, it can be determined that at least one target vehicle exists in the external area of ​​a vehicle not displayed on the first display screen (i.e., the actual area corresponding to the second area s12 of the raw image s1). In this case, although the target vehicle image is not displayed in the first display area a11 of the first display screen, the target vehicle is already within the camera's field of view, and the target vehicle may affect the current vehicle's driving status. At this time, the processor can generate and issue a first alert message. The display screen can receive the first alert message sent by the processor and display it in the second display area a12 of the first display interface, so that the driver is aware that a target vehicle exists in the external area of ​​the current vehicle and that the target vehicle may affect the current vehicle. For example, after seeing the first alert message displayed on the first display screen, the driver can promptly know that a target vehicle exists in the external area of ​​the vehicle and take precautions against the target vehicle.

[0091] In summary, this application provides a vehicle alert device, which includes a processor, a camera, and a first display screen. The processor identifies a target vehicle in the original image to monitor environmental changes in the external area of ​​the vehicle in real time. When a target vehicle image is detected in a cropped second area of ​​the original image (i.e., when a distant target vehicle is present in the surrounding area of ​​the vehicle), a first alert message is generated to remind the driver, and the second display area of ​​the first display screen is controlled to display the first alert message. Thus, by promptly alerting the driver when a target vehicle that may affect the driving status of the vehicle is present in the surrounding area, the driver's safety while driving the vehicle can be improved.

[0092] Please refer to Figure 5, which is a schematic diagram of another display interface a1 of the first display screen provided in this application embodiment. Figure 5 also shows the comparison between the display interface a1 of the first display screen and the image captured by the camera. In an exemplary embodiment, the shooting area of ​​the camera includes the first lane d1 and the second lane d2. The original image s1 sent by the shooting component to the processor has the first lane d1 and the second lane d2 corresponding to the actual lane. The processor identifies the target vehicle by performing target vehicle identification on the original image s1 sent by the camera. If the target vehicle image is found in the second lane d2 in the second area s12 of the original image s1, it means that there is a target vehicle in the second lane d2 behind the current vehicle. The target vehicle can be called a long-distance vehicle. It should be noted that a long-distance vehicle can refer to a vehicle whose distance from the target vehicle to the current vehicle is greater than 50 meters, such as 60 meters, 72 meters, 80 meters, 85 meters or 95 meters.

[0093] When the first reminder information is not displayed, the second display area a12 of the first display screen can be turned off or not lit. When the processor detects a distant target vehicle in the second lane d2 behind the current vehicle, it can light up the display area corresponding to the second lane d2 in the second display area a12 of the first display screen and display the first reminder information in the display area corresponding to the second lane d2. In this way, by dividing the first area s11 of the original image s1 and the first reminder information into sections on the first display screen, the presence of target vehicles in the surrounding areas can be displayed in real time while displaying the core area. This allows the driver to notice the presence of a distant vehicle behind the current vehicle, thereby enabling the driver to better understand the surrounding road conditions and take countermeasures in advance for vehicles that are about to appear.

[0094] Referring to Figure 5, in one optional embodiment, the first reminder information may include at least one of target image information or first text information. The target image information includes an image of the target vehicle, and the first text information includes at least one of vehicle information and distance information of the target vehicle. The first reminder information may include various types of information, such as text information, image information, voice information, and light information. For example, the first reminder information may be text, such as "The target vehicle is 100 meters behind," "Target vehicle 100 meters," "Large vehicle 100 meters," "Truck 100 meters," etc.; or, the first reminder information may be an image of the target vehicle, for example, the target vehicle image is segmented and extracted from the original image s1 obtained by the camera, and then reduced in size to form the first reminder information; or, the first reminder information may be a marked image obtained through image processing, which may be an image that highlights the target vehicle image in the original image s1, for example, an image obtained by highlighting the target vehicle image itself in the original image s1. Alternatively, the indication information may also be voice: "Large vehicle 100 meters behind," or the indication information may also be a red light flashing according to a preset pattern. It is understood that the highlighted mark in the embodiments of this application refers to highlighting the target vehicle image or text information with different colors, fonts or background colors, so that the driver can more easily identify the first reminder information on the display interface of the first display screen.

[0095] In this way, by displaying the first reminder information on the first display screen, the driver's perception of the surroundings and sides of the vehicle can be enhanced, further improving driving safety and comfort.

[0096] Please refer to Figure 6, which is a schematic diagram of another display interface a1 of the first display screen provided in this application embodiment. Figure 6 also shows a comparison between the display interface a1 of the first display screen and the image captured by the camera. In an optional embodiment, the first display area a11 may include a prompt area a111 and a danger area a112. The first area s11 of the original image s1 includes a first sub-area and a second sub-area. The display content of the prompt area a111 is obtained based on the first sub-area of ​​the original image s1, and the display content of the danger area a112 is obtained based on the second sub-area of ​​the original image s1. The distance between the actual area corresponding to the first sub-area of ​​the original image s1 and the current vehicle is greater than the distance between the actual area corresponding to the second sub-area of ​​the original image s1 and the current vehicle. That is, the actual area captured in the original image s1 can be divided into multiple sub-areas, and the multiple sub-areas can be arranged in a direction away from the current vehicle. For example, the actual area corresponding to the first sub-area is located on the side of the actual area corresponding to the second sub-area away from the current vehicle.

[0097] In other words, the first display area a11 can be divided into multiple sub-areas (e.g., warning area a111 and danger area a112) according to the distance between the target vehicle and the current vehicle corresponding to the target vehicle image displayed in the first display area a11. For example, when the target vehicle image is displayed in the warning area a111, the driver can assume that the distance between the target vehicle and the current vehicle is far and there is no need to take immediate action. When the target vehicle image is displayed in the danger area a112, the driver can assume that the distance between the target vehicle and the current vehicle is close and the target vehicle may affect the driving status of the current vehicle. The driver needs to take immediate action to avoid a safety accident.

[0098] Referring to Figure 6, in an optional embodiment, the processor can further be configured to: in response to recognizing the presence of a target vehicle image in a first region s11 of the original image s1, obtain the display position of the target vehicle image in the first display area a11; when the target vehicle image is displayed in the prompt area a111 of the first display screen, send first background color information to the first display screen and control the prompt area a111 of the first display screen to display the first background color. When the target vehicle image is displayed in the danger area a112, send second background color information to the first display screen and control the danger area a112 of the first display screen to display the second background color. The first display screen can make the prompt area a111 display the first background color according to the first background color information, and the first display screen can also make the danger area a112 display the second background color according to the second background color information. The first background color and the second background color are different colors; for example, the first background color is green and the second background color is red.

[0099] When the first display area a11 displays multiple lanes simultaneously, only the background color of the lane containing the target vehicle image can be adjusted. For example, as shown in Figure 6, the current first display area a11 contains two target vehicle images: a first target vehicle image and a second target vehicle image. The first target vehicle image is located in the first lane d1 of the prompt area a111, so the background color of the area containing the first lane d1 of the prompt area a111 is green. The first target vehicle image is located in the second lane d2 of the danger area a112, so the background color of the area containing the second lane d2 of the danger area a112 is red. By setting different background colors, the current location of the target vehicle image can be displayed to the driver more intuitively, enhancing the driver's perception of target vehicles around and to the side and rear of the vehicle.

[0100] Please refer to Figures 7 and 8. Figure 7 is a schematic diagram of another display interface a1 of the first display screen provided in an embodiment of this application, and Figure 8 is a schematic diagram of another display interface a1 of the first display screen provided in an embodiment of this application. Figures 7 and 8 also show a comparison between the display interface a1 of the first display screen and the image captured by the camera. In an optional embodiment, the processor can also be used to: in response to recognizing the presence of a target vehicle image in the first area s11, acquire the driving data of the target vehicle, the driving data including the driving speed and distance of the target vehicle relative to other vehicles; when the driving data exceeds a preset driving data range, generate a second reminder message, the second reminder message including second text information; control the first display screen to display a second display interface, the second display interface including a first display area a11 and a third display area a13, the third display area a13 being used to display the second text information. The second display interface may also include a second display area a12.

[0101] In this embodiment, the camera may include multiple depth cameras, which can capture images of the surrounding environment of the current vehicle. The processor can obtain the first position of the target vehicle based on the target vehicle image in the original image s1, and obtain the distance between the first position and the current vehicle based on the first position of the target vehicle. The distance can be obtained multiple times by setting a fixed interval time, and then the speed of the target vehicle relative to the current vehicle can be obtained based on the distance and the interval time.

[0102] When the target vehicle's speed relative to the current vehicle is greater than or equal to a preset relative speed, and the distance between the target vehicle and the current vehicle is less than or equal to a preset distance, it is considered that the target vehicle may pose a rear-end collision risk. At this time, the processor can generate and issue a second warning message. The display screen can receive the second warning message sent by the processor and display it in the third display area a13 of the second display interface, so that the driver is aware of the risk of a rear-end collision with the target vehicle behind the current vehicle. For example, after seeing the first warning message displayed on the first display screen, the driver can make timely driving adjustments to avoid a rear-end collision, thus improving driving safety. For example, the preset relative speed can range from 5 m / s to 30 m / s, such as 5 m / s, 10 m / s, 25 m / s, or 30 m / s; the preset distance can range from 10 meters to 50 meters, such as 10 meters, 16 meters, 10 meters, 30 meters, or 45 meters.

[0103] For example, the second warning message is text such as: "Target vehicle is 10 meters behind", "Beware of rear-end collision!", "Large vehicle 10 meters away", etc.

[0104] In one exemplary implementation, the camera's shooting area includes a first lane d1 and a second lane d2. The original image s1 sent by the shooting component to the processor has the first lane d1 and the second lane d2 corresponding to the actual lanes. The processor identifies whether the target vehicle is at risk of rear-end collision by acquiring the target vehicle's driving data.

[0105] When the second warning information is not displayed, the third display area a13 of the first display screen can be turned off or not lit. When the processor detects a target vehicle with a rear-end collision risk located in the second lane d2 behind the current vehicle, it can light up the display area corresponding to the second lane d2 in the third display area a13 of the first display screen and display the second warning information in the display area corresponding to the second lane d2. In this way, by dividing the first area s11 of the original image s1 and the second warning information into sections on the first display screen, the core area can be displayed in real time while the dangerous situation in the surrounding environment is displayed.

[0106] In one alternative implementation, the vehicle further includes a distance sensor, through which the current vehicle can obtain the driving data of the target vehicle.

[0107] As shown in Figure 8, in an optional embodiment, the second reminder information may further include a first marked image, which is an image after marking the target vehicle image in the first region s11 of the original image s1; the processor is also used to control the first display area a11 of the second display interface to display the first marked image. The first marked image may be an image that highlights the target vehicle image in the first region s11 of the original image s1, or it may be obtained by highlighting the entire display area corresponding to the lane where the target vehicle image is located.

[0108] Please refer to Figure 9, which is a schematic diagram of another display interface a1 of the first display screen provided in an embodiment of this application. Figure 9 also shows a comparison between the display interface a1 of the first display screen and the image captured by the camera. In an optional embodiment, the processor can further be used to: in response to the presence of a target vehicle image in the second region s12 where no image is recognized, control the first display screen to display a third display interface, the third display interface including the first display area a11; wherein the size of the first display interface and the size of the first display area in the third display interface are the same. That is, by switching the display ratio of the first display screen, a reminder of the target vehicle can be displayed on the first display screen to alert the driver to the target vehicle.

[0109] The size of the first display area a11 in the first display screen can be enlarged or reduced depending on different situations. For example, when the target vehicle image is not detected in the second area s12 of the original image s1, it means that there is no target vehicle behind the current vehicle. Only the first display area a11 can be displayed on the first display screen, that is, only the first area s11 of the original image s1 is displayed on the first display screen to improve the driver's viewing experience of the first display screen.

[0110] Please refer to Figure 10, which is a flowchart of another method for identifying a target vehicle in the original image s1 according to an embodiment of this application. In this embodiment, the processor can identify the target vehicle in the original image s1 in the following two ways.

[0111] The first method for identifying a target vehicle in the original image s1 includes the processor further being used to: detect a vehicle in a second region s12 of the original image s1; in response to detecting a vehicle image to be identified in the second region s12 of the original image s1, obtain the category information of the vehicle to be identified corresponding to the vehicle image to be identified; if the category of the vehicle to be identified belongs to a preset large vehicle, determine the vehicle image to be identified as the target vehicle image.

[0112] Because large vehicles pose a higher risk, a first alert can be generated immediately when a large vehicle is detected in the second region s12 of the original image s1, so as to promptly remind the driver.

[0113] In one exemplary embodiment, the specification information of the vehicle to be identified corresponding to the image of the vehicle to be identified can also be obtained; if the height of the vehicle to be identified is greater than a preset height, or the width of the vehicle to be identified is greater than a preset width, or the height of the vehicle to be identified is greater than a preset height and the width of the vehicle to be identified is greater than a preset width, then the image of the vehicle to be identified is determined as the target vehicle image.

[0114] The second method for target vehicle identification of the original image s1 includes, whereby the processor can also be used to:

[0115] Vehicle detection is performed on the first region s11 of the original image s1; in response to the absence of a vehicle image to be identified in the first region s11 of the original image s1, vehicle detection is performed on the second region s12 of the original image s1; in response to the presence of a vehicle image to be identified in the second region s12 of the original image s1, the driving data of the vehicle to be identified corresponding to the vehicle image to be identified is obtained; based on the driving data of the vehicle to be identified, a first time interval is estimated for the vehicle image to be identified to move from its current position in the original image s1 to the first region s11 of the original image s1; if the first time interval is less than a preset time, the vehicle image to be identified is determined as the target vehicle image.

[0116] When a vehicle image to be identified is detected in the first region s11 of the original image s1, it indicates that a vehicle exists in the core region that is close to the current vehicle. If a vehicle also exists in the surrounding region that is far from the current vehicle, since the vehicles in the surrounding region are located on the side of the core region that is far away from the current vehicle, the vehicles in the surrounding region will not directly affect the driving status of the current vehicle, and there is no need to detect the vehicles in the surrounding region.

[0117] When the image of the vehicle to be identified is not detected in the first region s11 of the original image s1, it indicates that there are no other vehicles in the core region closer to the current vehicle. If there are vehicles in the surrounding region farther away from the current vehicle, these vehicles will directly affect the driving state of the current vehicle. Therefore, vehicles in the surrounding region can be detected, and the driving data of the vehicle to be identified can be obtained. If, based on the driving data of the vehicle to be identified, it is estimated that the image of the vehicle to be identified can be located in the first region s11 of the original image s1 within the first time period, it indicates that the vehicle to be identified may affect the driving state of the current vehicle, and the image of the vehicle to be identified can be identified as the target vehicle image.

[0118] In an alternative implementation, if the original image s1 sent by the imaging component to the processor contains multiple lanes corresponding to the actual lanes, the above-described method of identifying target vehicles in the original image s1 can be performed on each of the multiple lanes.

[0119] For example, please refer to Figure 11. Figure 11 is a flowchart of a target vehicle identification process for an original image s1 provided in an embodiment of this application. The processor can first perform vehicle detection on each lane in the first display area of ​​the first display screen. For lanes where there is no image of the vehicle to be identified in the first display area, it can further determine whether there is an image of the vehicle to be identified in the second area that was cropped in the original image. If there is an image of the vehicle to be identified in the lane, and it is estimated that the image of the vehicle to be identified will enter the first display area of ​​the first display screen within a first time period, in other words, the vehicle to be identified can be tracked to determine whether the vehicle to be identified can be displayed in the first display area within a first time period. Then, the image of the vehicle to be identified in the lane is determined as the target vehicle image, and a first reminder message is displayed in the second display area of ​​the first display screen.

[0120] Please refer to Figure 10. When the processor detects a large vehicle in the second lane d2 of the second region s12 of the original image s1, it illuminates the area of ​​the second lane d2 in the second display area a12 of the first display screen and displays a first warning message (large vehicle 100 meters) in the area of ​​the second lane d2. The processor then tracks the target vehicle in real time using a camera and identifies the position of the target vehicle image in real time. If at least a portion of the target vehicle image is located in the first region s11 of the original image s1, that is, if at least a portion of the target vehicle image has entered the first display area a11 of the first display screen, the first warning message in the second display area a12 of the first display screen can be canceled. Based on the real-time position of the target vehicle image, the image is displayed in the warning area a111 and the danger area a112 of the first display area a11. When the target vehicle image is located in the warning area a111 or the danger area a112, the background color of the warning area a111 or the danger area a112 can be changed to enhance the warning effect on the driver. Subsequently, if the detected target vehicle image is too close to the current vehicle and there is a risk of rear-end collision, a second warning message will be displayed in the third display area a13.

[0121] Please refer to Figure 12, which is a schematic diagram of another display interface a1 of the first display screen provided in an embodiment of this application. Figure 12 also shows a comparison between the display interface a1 of the first display screen and the original image s1 captured by the camera. In an optional embodiment, the processor can also be used to: after determining the image of the vehicle to be identified as the target vehicle image, continue to receive the original image s1 sent by the camera; obtain the position of the target vehicle image in the original image s1; in response to at least a portion of the target vehicle image being located in the first region s11 of the original image s1, generate third reminder information, the third reminder information including a second marker image, the second marker image being an image after marking the target vehicle image in the first region s11 of the original image s1; control the first display screen to display a third display interface, the third display interface including a first display area a11, the first display area a11 of the third display interface being used to display the second marker image. The second marker image can be an image that highlights the target vehicle image in the first region s11 of the original image s1, or it can be obtained by highlighting the entire display area corresponding to the lane where the target vehicle image is located. At this time, the second display area a12 of the first display screen a1 may not display the first reminder information.

[0122] Please refer to Figures 13 and 14. Figure 13 is a schematic diagram of the application environment of another vehicle reminder device provided in this application embodiment. Figure 14 is a schematic diagram of the display interface a2 of a second display screen 140 provided in this application embodiment. Figure 15 is a schematic diagram of another display interface a2 of a second display screen 140 provided in this application embodiment. Figures 14 and 15 also show a comparison between the display interface a2 of the second display screen 140 and the original image s1 captured by the camera. In an optional embodiment, the vehicle may further include a second display screen 140, the size of which is larger than the size of the display area of ​​the first display screen 130. The processor may also be used to: after generating the first reminder information, control the second display screen 140 to display a fourth display interface, the fourth display interface including a fourth display area a14 and a fifth display area a15. The display content of the fourth display area a14 is obtained based on the first area s11 of the original image s1, and the fifth display area a15 is used to display the first reminder information.

[0123] Optionally, the first alert information includes a third marked image, which is an image of the target vehicle in the second region s12 of the image after being marked.

[0124] As shown in Figure 15, the second display screen may include a central control screen. Since the size of the central control screen is larger than that of the electronic rearview mirror display, the central control screen can simultaneously display the original image s1 captured by the camera, improving the driver's viewing experience. For example, when the second display area of ​​the original image does not contain the target vehicle image, the content displayed on the first display screen is obtained based on the first area of ​​the original image, and the original image can be displayed on the second display screen.

[0125] Please refer to Figures 15 and 16. Figure 16 is a schematic diagram of another display interface of the second display screen provided in an embodiment of this application. As shown in Figure 16, when the second display area of ​​the original image does not contain a target vehicle image, the content displayed on the second display screen is obtained based on the first area of ​​the original image. As shown in Figure 15, when the second display area of ​​the original image does not contain a target vehicle image, the second display screen can display the original image and display the first reminder information in the fifth display area.

[0126] The first and second displays in this application embodiment can be any product or component with display function, such as a display motherboard, mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, in-vehicle display device, smartwatch, fitness wristband, personal digital assistant, etc.

[0127] In summary, this application provides a vehicle alert device, which includes a processor, a camera, and a first display screen. The processor identifies a target vehicle in the original image to monitor environmental changes in the external area of ​​the vehicle in real time. When a target vehicle image is detected in a cropped second area of ​​the original image (i.e., when a distant target vehicle is present in the surrounding area of ​​the vehicle), a first alert message is generated to remind the driver, and the second display area of ​​the first display screen is controlled to display the first alert message. Thus, by promptly alerting the driver when a target vehicle that may affect the driving status of the vehicle is present in the surrounding area, the driver's safety while driving the vehicle can be improved.

[0128] Figure 17 is a flowchart of a vehicle alerting method provided in an embodiment of this application. Referring to Figure 17, this method can be used in a processor in a vehicle, which also includes a camera and a first display screen. The method may include the following steps:

[0129] Step 101: Receive the original image, which includes a first region and a second region located outside the first region.

[0130] The original image can be an image captured by a camera on the vehicle.

[0131] Step 102: Identify the target vehicle in the original image.

[0132] Step 103: In response to the recognition that a target vehicle image exists in the second region of the original image, generate a first alert message.

[0133] Step 104: Control the first display screen to display the first display interface. The first display interface includes a first display area and a second display area. The content displayed in the first display area is obtained based on the first area of ​​the original image. The second display area is used to display the first reminder information.

[0134] In summary, this application provides a vehicle alert method. By performing target vehicle identification on the original image, it monitors environmental changes in the external area of ​​the current vehicle in real time. When a target vehicle image is identified in a cropped second area of ​​the original image, i.e., when a distant target vehicle exists in the surrounding area of ​​the current vehicle, a first alert message is generated to remind the driver, and the second display area of ​​the first display screen is controlled to display the first alert message. Thus, by promptly alerting the driver when a target vehicle that may affect the driving status of the current vehicle exists in the surrounding area, the driver's safety while driving the current vehicle can be improved.

[0135] Figure 18 is a flowchart of another vehicle alerting method provided in an embodiment of this application. Referring to Figure 18, this method can be used in a processor in a vehicle, which also includes a camera and a first display screen. The method may include the following steps:

[0136] Step 201: Receive the original image.

[0137] The original image can be an image captured by a camera on the vehicle. The original image includes a first region and a second region located outside the first region. The original image sent by the camera to the processor is the actual captured image. The processor can perform cropping processing on the received original image. The first region of the original image is the area retained after cropping, and the second region of the original image is the area cropped out after cropping.

[0138] Step 202: Perform target vehicle identification on the first region of the original image.

[0139] Target vehicle identification of the original image can be divided into two parts: target vehicle identification of a first region of the original image and target vehicle identification of a second region of the original image. That is, target vehicle identification can be performed on the first region and the second region of the original image respectively.

[0140] Step 203: In response to the recognition that a target vehicle image exists in the first region, obtain the driving data of the target vehicle.

[0141] The driving data includes the target vehicle's speed and distance relative to other vehicles.

[0142] If a target vehicle image is identified in the first region, step 204 can be executed; if no target vehicle image is identified in the first region, step 207 can be executed.

[0143] Step 204: When the driving data exceeds the preset driving data range, a second reminder message is generated.

[0144] The second reminder message includes a second text message. For example, the second reminder message may be text such as: "Target vehicle is 10 meters behind", "Beware of rear-end collision!", "Large vehicle 10 meters away", etc.

[0145] When the target vehicle's speed relative to the current vehicle is greater than or equal to a preset relative speed, and the distance between the target vehicle and the current vehicle is less than or equal to a preset distance, it is considered that there may be a risk of rear-end collision with the target vehicle. At this time, the processor can generate and issue a second warning message. The display screen can receive the second warning message sent by the processor and display it in the third display area of ​​the second display interface, so that the driver is aware that there is a risk of rear-end collision with the target vehicle behind the current vehicle.

[0146] Step 205: Control the first display screen to display the second display interface. The second display interface includes a first display area and a third display area. The third display area is used to display the second text information.

[0147] Optionally, the second reminder information may also include a first marked image, which is an image of the target vehicle in a first region of the original image after being marked; the processor is also used to control the first display area of ​​the second display interface to display the first marked image.

[0148] In one optional implementation, the first display area may include a warning area and a danger area. The first area of ​​the original image includes a first sub-area and a second sub-area. The display content of the warning area is obtained based on the first sub-area of ​​the original image, and the display content of the danger area is obtained based on the second sub-area of ​​the original image. The distance between the actual area corresponding to the first sub-area of ​​the original image and the vehicle is greater than the distance between the actual area corresponding to the second sub-area of ​​the original image and the vehicle.

[0149] In response to the identification of a target vehicle image in a first region of the original image, the display position of the target vehicle image in the first display area is obtained; when the target vehicle image is displayed in the prompt area, first background color information is sent to the first display screen, and the prompt area of ​​the first display screen is controlled to display the first background color; when the target vehicle image is displayed in the danger zone, second background color information is sent to the first display screen, and the danger zone of the first display screen is controlled to display the second background color. The first background color and the second background color can be different background colors; for example, the first background color is green, and the second background color is red.

[0150] Step 206: Perform target vehicle identification on the second region of the original image.

[0151] Target vehicle identification in the second region of the original image can be performed in the following two ways:

[0152] Method 1: Due to the higher risk factor of large vehicles, a first alert message can be generated immediately upon detecting the presence of a large vehicle in the second region of the original image, thus promptly alerting the driver. Referring to Figure 19, step 206 of Method 1 may include the following sub-steps:

[0153] Sub-step 2061: Perform vehicle detection on the second region of the original image.

[0154] Sub-step 2062: In response to detecting the vehicle image to be identified in the second region of the original image, obtain the category information of the vehicle to be identified corresponding to the vehicle image to be identified.

[0155] Sub-step 2063: If the vehicle to be identified belongs to the preset category of large vehicles, the image of the vehicle to be identified is determined as the target vehicle image.

[0156] Sub-step 2064: If the category of the vehicle to be identified does not belong to the preset large vehicle category, then the target vehicle is not identified in the second region of the original image.

[0157] After substep 2064, substep 2061 can be executed.

[0158] Method 2: When a vehicle image to be identified is detected in the first region of the original image, it indicates that a vehicle exists in the core region that is relatively close to the current vehicle. If a vehicle also exists in the surrounding region that is relatively far from the current vehicle, since the vehicles in the surrounding region are located on the side of the core region that is far away from the current vehicle, the vehicles in the surrounding region will not directly affect the driving status of the current vehicle, and there is no need to detect the vehicles in the surrounding region.

[0159] When the image of the vehicle to be identified is not detected in the first region of the original image, it indicates that there are no other vehicles in the core region closer to the current vehicle. If there are vehicles in the surrounding region farther away from the current vehicle, these vehicles will directly affect the driving state of the current vehicle. Therefore, vehicles in the surrounding region can be detected, and the driving data of the vehicle to be identified can be obtained. If, based on the driving data of the vehicle to be identified, it is estimated that the image of the vehicle to be identified can be located in the first region of the original image within the first time period, it indicates that the vehicle to be identified may affect the driving state of the current vehicle, and the image of the vehicle to be identified can be identified as the target vehicle image. Please refer to Figure 20. Method 2 of step 206 may include the following sub-steps:

[0160] Sub-step 2065: Perform vehicle detection on the first region of the original image.

[0161] Sub-step 2066: In response to the absence of a vehicle image to be identified in the first region of the original image, vehicle detection is performed in the second region of the original image.

[0162] Sub-step 2067: In response to detecting the image of the vehicle to be identified in the second region of the original image, obtain the driving data of the vehicle to be identified corresponding to the image of the vehicle to be identified.

[0163] Sub-step 2068: Based on the driving data of the vehicle to be identified, estimate the first time it takes for the image of the vehicle to be identified to move from its current position in the original image to the first region of the original image.

[0164] Sub-step 2069: If the first duration is less than the preset time, then the image of the vehicle to be identified is determined as the target vehicle image.

[0165] If the first duration exceeds the preset time, it can be assumed that the target vehicle was not identified in the second region of the original image.

[0166] It should be noted that sub-step 2065 and step 202 can be executed selectively. That is, after executing step 202, step 2066 can be executed directly.

[0167] In one optional implementation, after identifying the vehicle image to be recognized as the target vehicle image, the system continues to receive the original image sent by the camera; the position of the target vehicle image in the original image is obtained; in response to at least a portion of the target vehicle image being located in a first region of the original image, a third alert message is generated, the third alert message including a second marker image, the second marker image being an image of the target vehicle image in the first region of the original image after being marked; the system controls the first display screen to display a third display interface, the third display interface including a first display area, the first display area of ​​the third display interface being used to display the second marker image. The second marker image can be an image of the target vehicle image in the first region of the original image that is highlighted, or it can be obtained by highlighting the entire display area corresponding to the lane where the target vehicle image is located. At this time, the second display area of ​​the first display screen may not display the first alert message.

[0168] Step 207: If the target vehicle image is not identified in the second region of the original image, control the first display screen to display the third display interface, which includes the first display area.

[0169] The size of the first display interface is the same as the size of the first display area in the third display interface. The size of the first display area in the first display screen can be enlarged or reduced according to different situations. For example, when no target vehicle image is detected in the second area of ​​the original image, it means that there is no target vehicle behind the current vehicle. In this case, only the first display area can be displayed on the first display screen. That is, the display content displayed on the first display screen is obtained only from the first area of ​​the original image, so as to improve the driver's viewing experience of the first display screen.

[0170] Step 208: If a target vehicle image is detected in the second region of the original image, a first alert message is generated.

[0171] The first reminder information includes at least one of target image information or first text information. The target image information includes an image of the target vehicle, and the first text information includes at least one of vehicle information and distance information of the target vehicle.

[0172] Step 209: Control the first display screen to display the first display interface. The first display interface includes a first display area and a second display area. The content displayed in the first display area is obtained based on the first area of ​​the original image. The second display area is used to display the first reminder information.

[0173] The camera is used to capture real-time images of the external area of ​​the current vehicle and sends the captured raw images to the processor, enabling the processor to monitor environmental changes in the external area of ​​the vehicle in real time. Target vehicle identification can be performed on the raw images to determine if at least one target vehicle exists in the external area of ​​a vehicle not displayed on the first display screen (i.e., the actual area corresponding to the second area of ​​the raw image). In this case, although the target vehicle image is not displayed in the first display area of ​​the first display screen, the target vehicle is already within the camera's field of view, and the target vehicle may affect the current vehicle's driving status. At this time, the processor can generate and issue a first alert message. The display screen can receive the first alert message sent by the processor and display it in the second display area of ​​the first display interface, so that the driver is aware that a target vehicle exists in the external area of ​​the current vehicle and that the target vehicle may affect the current vehicle. For example, after seeing the first alert message displayed on the first display screen, the driver can promptly know that a target vehicle exists in the external area of ​​the vehicle and take precautions against the target vehicle.

[0174] In an optional embodiment, the vehicle may further include a second display screen, the size of which is larger than the size of the display area of ​​the first display screen. After generating the first reminder information, the second display screen is controlled to display a fourth display interface, which includes a fourth display area and a fifth display area. The content displayed in the fourth display area is obtained based on the first area of ​​the original image, and the fifth display area is used to display the first reminder information. The first reminder information includes a third marked image, which is an image of the target vehicle image in the second area of ​​the original image after marking it.

[0175] In one optional implementation, the first display area may include a warning area and a danger area. The first area of ​​the original image includes a first sub-area and a second sub-area. The content displayed in the warning area is obtained based on the first sub-area of ​​the original image, and the content displayed in the danger area is obtained based on the second sub-area of ​​the original image. The distance between the actual area corresponding to the first sub-area of ​​the original image and the current vehicle is greater than the distance between the actual area corresponding to the second sub-area of ​​the original image and the current vehicle. That is, a portion of the actual area captured in the original image can be divided into multiple sub-areas, and these sub-areas can be arranged in a direction away from the current vehicle. For example, the actual area corresponding to the first sub-area is located on the side of the actual area corresponding to the second sub-area that is away from the current vehicle.

[0176] In other words, the first display area can be divided into multiple sub-areas (e.g., warning area and danger area) according to the distance between the target vehicle and the current vehicle corresponding to the target vehicle image displayed in the first display area.

[0177] In one optional implementation, in response to identifying the presence of a target vehicle image in a first region of the original image, the display position of the target vehicle image in the first display area is obtained; when the target vehicle image is displayed in the prompt area of ​​the first display screen, first background color information is sent to the first display screen, and the prompt area of ​​the first display screen is controlled to display the first background color. When the target vehicle image is displayed in a danger zone, second background color information is sent to the first display screen, and the danger zone of the first display screen is controlled to display the second background color. The first display screen can display the first background color in the prompt area according to the first background color information, and the first display screen can also display the second background color in the danger zone according to the second background color information. The first background color and the second background color are different colors; for example, the first background color is green, and the second background color is red.

[0178] Optionally, when the first display area displays multiple lanes simultaneously, only the background color of the lane where the target vehicle image is located can be adjusted.

[0179] In summary, this application provides a vehicle alert method. By performing target vehicle identification on the original image, it monitors environmental changes in the external area of ​​the current vehicle in real time. When a target vehicle image is identified in a cropped second area of ​​the original image, i.e., when a distant target vehicle exists in the surrounding area of ​​the current vehicle, a first alert message is generated to remind the driver, and the second display area of ​​the first display screen is controlled to display the first alert message. Thus, by promptly alerting the driver when a target vehicle that may affect the driving status of the current vehicle exists in the surrounding area, the driver's safety while driving the current vehicle can be improved.
