The secondary spherical display device of the in-vehicle display module is used to display image information outside the vehicle from a horizontal angle of the vehicle.

[0008] The off-vehicle monitoring system provided by the embodiment of the present invention uses multiple groups of monitoring devices arranged around the outside of the vehicle to monitor the outside environment of the vehicle in all directions, that is, the first camera is used to collect image information of all directions outside the vehicle, the radar is used to collect the distance of foreign objects around the vehicle, and the main spherical display device of the in-vehicle display module is used to display the image information of all directions outside the vehicle from a bird's-eye view directly above the vehicle, so that the driver can intuitively see the bird's-eye view around the vehicle, which helps to avoid blind spots and dead angles. The secondary spherical display device of the in-vehicle display module displays the image information of the outside of the vehicle from the horizontal angle of the vehicle, so that the driver can pay attention to the details of the outside of the vehicle, further improving driving safety and driving experience, and is suitable for a variety of driving scenarios.

[0009] In an optional embodiment, the main spherical display device and the auxiliary spherical display device both include a spherical display screen, a base and fixing ribs, and the fixing ribs are used to connect the base and the spherical display screen to fix the spherical display screen on the base.

[0014] The adjustment module is used to adjust the angle of the spherical display screen based on the driver's eye position so that the driver's line of sight is located at a bird's-eye view angle directly above the vehicle.

[0015] The off-vehicle monitoring system provided by the embodiment of the present invention can collect the driver's image information in real time by using the second camera to determine the driver's eye position, and then use the adjustment module to automatically adjust the angle of the spherical display screen based on the driver's eye position, ensuring that the driver's line of sight is always located at a bird's-eye view angle directly above the vehicle, so that the driver can always see the best bird's-eye view panoramic image, avoiding visual fatigue and misjudgment caused by improper viewing angle, helping the driver to fully understand the environment around the vehicle, reducing blind spots and dead angles, and improving driving safety. In addition, the adjustment process does not require the driver to manually adjust the display screen angle, thereby improving the degree of intelligence.

[0022] When the first camera of the vehicle exterior monitoring module does not recognize that a foreign object is present outside the vehicle, a radar belonging to the same monitoring device group as the first camera is turned off.

[0023] The off-vehicle monitoring system provided by the embodiment of the present invention saves energy and extends the life of the equipment by activating the radar in the same group as the first camera only when the first camera recognizes the presence of a foreign object outside the vehicle. When the first camera does not recognize the foreign object, the radar will automatically shut down, further reducing energy consumption and improving the overall efficiency of the system.

[0024] In an optional embodiment, the system further includes a data processing module;

[0025] When the first camera of the vehicle exterior monitoring module identifies that a foreign object is present outside the vehicle, the data processing module is used to mark the foreign object in the image information of all directions outside the vehicle collected by the first camera.

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0039] Traditional vehicle-mounted monitoring systems usually only focus on a single direction. This one-way monitoring method has obvious limitations and cannot fully cover the environment around the vehicle, especially in complex traffic environments, where accidents often occur in areas outside the driver's sight. The off-vehicle monitoring system provided by the embodiment of the present invention uses multiple sets of monitoring devices arranged around the outside of the vehicle to monitor the outside environment of the vehicle in all directions, that is, the first camera collects image information from all directions outside the vehicle, and the radar collects the distance of foreign objects around the vehicle. The main spherical display device of the in-vehicle display module displays image information from all directions outside the vehicle from a bird's-eye view directly above the vehicle, so that the driver can intuitively see the bird's-eye view around the vehicle, which helps to avoid blind spots and dead angles. The secondary spherical display device displays the image information of the outside of the vehicle from the horizontal angle of the vehicle, so that the driver can pay attention to the details of the outside of the vehicle, further improving driving safety and driving experience, and is suitable for a variety of driving scenarios.

[0040] In this embodiment, a vehicle external monitoring system is provided. Figure 1 is a schematic diagram of an off-vehicle monitoring system according to an embodiment of the present invention. Figure 1As shown, the system includes an outside-vehicle monitoring module and an inside-vehicle display module; the outside-vehicle monitoring module includes multiple groups of monitoring devices, which are arranged around the outside of the vehicle, and any group of monitoring devices includes a first camera and a radar, the first camera is used to collect image information outside the vehicle, and the radar is used to collect the distance of foreign objects around the vehicle; the inside-vehicle display module includes a main spherical display device and a secondary spherical display device, which are arranged on the instrument panel frame inside the vehicle; the outside-vehicle monitoring module is used to collect image information in all directions outside the vehicle and the distance of foreign objects around the vehicle, the main spherical display device of the inside-vehicle display module is used to display image information in all directions outside the vehicle from a bird's-eye view angle directly above the vehicle, and the secondary spherical display device of the inside-vehicle display module is used to display image information outside the vehicle from a horizontal angle of the vehicle.

[0041] Specifically, the vehicle exterior monitoring module includes multiple groups of monitoring devices, which are arranged in multiple areas outside the vehicle to collect image information from all directions outside the vehicle and realize all-round monitoring of the vehicle exterior. The vehicle exterior is divided into the front area, the left area, the right area, the rear area and the roof area. One or more groups of monitoring devices can be arranged in each area, and each group of monitoring devices includes one or more first cameras and a radar. Figure 2 is a schematic diagram of a monitoring device according to an embodiment of the present invention. Figure 2 As shown, taking the area in front of the vehicle and the area on the left side of the vehicle as examples, it is assumed that a group of monitoring devices are respectively set in these two areas to collect image information of the corresponding areas. Figure 3 is a schematic diagram of an in-vehicle display module according to an embodiment of the present invention, such as Figure 3As shown, the main sphere display device and the secondary sphere display device in the in-vehicle display module are both arranged on the instrument panel frame inside the vehicle, specifically on the right side of the steering wheel, with the main sphere display device in front and the secondary sphere display device in the back. Among them, the main sphere display device is used to display the image information of all directions outside the vehicle collected by the external monitoring module, and is displayed from a bird's-eye view angle directly above the vehicle, so that the driver can observe the bird's-eye panoramic image of the outside of the vehicle in the car. The secondary sphere display device is a supplementary display of the main sphere display device. When any first camera recognizes that there is a foreign object outside the vehicle, the foreign object can be a human body, other living things or other objects, etc. The secondary sphere display device displays the external image information of the vehicle collected by the first camera from a horizontal angle based on the distance between the foreign object and the vehicle, so that the driver can intuitively observe the details of the outside of the vehicle. Optionally, it is assumed that the display range of the main sphere display device and the secondary sphere display device is 5 meters, that is, the image information within 5 meters from the vehicle is selected from the image information collected by the first camera for display. The display range is only an example and is not limited. By using multiple sets of monitoring devices installed around the outside of the vehicle to monitor the external environment in all directions, and using the main spherical display device of the in-vehicle display module to display image information of all directions outside the vehicle from a bird's-eye view directly above the vehicle, it helps to avoid blind spots and dead angles. The secondary spherical display device of the in-vehicle display module displays image information outside the vehicle from the horizontal angle of the vehicle, so that the driver can pay attention to the details outside the vehicle, further improving driving safety and driving experience.

[0042] In some optional embodiments, the main spherical display device and the auxiliary spherical display device both include a spherical display screen, a base and fixing ribs, and the fixing ribs are used to connect the base and the spherical display screen to fix the spherical display screen on the base.

[0043] Specifically, Figure 4 is a schematic diagram of a main sphere display device according to an embodiment of the present invention. Figure 4 As shown, the spherical display screen of the main spherical display device is fixed on the base through fixing ribs. The base can be circular or in other shapes, which is not limited in the embodiment of the present invention. Figure 4 The design of the base and the fixing ribs makes it easy to install and disassemble the main sphere display device and the auxiliary sphere display device, and is convenient for daily maintenance and replacement.

[0044] In some optional embodiments, the main sphere display device also includes a second camera and an adjustment module; the spherical display screen of the main sphere display device is used to display image information in all directions outside the vehicle from a bird's-eye view directly above the vehicle; the second camera is used to collect image information of the driver to determine the driver's eye position; the adjustment module is used to adjust the angle of the spherical display screen based on the driver's eye position so that the driver's line of sight is located at a bird's-eye view directly above the vehicle.

[0045] Specifically, since the spherical display screen of the main spherical display device provides the driver with a bird's-eye view of the outside of the vehicle, and the driver may observe the spherical display screen of the main spherical display device at different angles due to different heights or different driving postures, etc., thus having different visual experiences. Therefore, the driver's image information can be continuously collected through the second camera of the main spherical display device to determine the position of the driver's eyes. The adjustment module adjusts the angle of the spherical display screen by adjusting the angle of the base, so that the driver can have a perspective of looking down on the vehicle from directly above the vehicle no matter where he is, thereby improving the visual experience and avoiding visual fatigue and misjudgment caused by improper perspective, helping the driver to fully understand the environment around the vehicle, reducing blind spots and dead angles, and improving driving safety. In addition, the adjustment process does not require the driver to manually adjust the angle of the display screen, thereby improving the degree of intelligence.

[0046] In some optional embodiments, the spherical display screen includes multiple screen layers, the screen layers include a character layer, an environment layer and other individual layers; the character layer is used to display character images in image information in all directions outside the vehicle; the environment layer is used to display environment images in image information in all directions outside the vehicle; and the other individual layers are used to display other images except characters and environments in image information in all directions outside the vehicle.

[0047] Specifically, refer to Figure 4As shown, the spherical display screen is composed of multiple transparent circular flat OLED (Organic Light-Emitting Diode) screens, each of which constitutes a screen layer, and provides a three-dimensional visual effect for the driver through multiple screen layers. After any first camera of the vehicle exterior monitoring module collects image information of any area, the first camera identifies the environment, people and other individuals in the image information of the area, so as to display them on different screen layers of the spherical display screen. Optionally, other individuals are other living beings or other objects other than the environment and people in the image information. Assume that the first screen layer of the spherical display screen is the environment layer, the second screen layer is the person layer, the third screen layer is the other individual layer, the fourth screen layer is the person layer, the fifth screen layer is the other individual layer, and the sixth screen layer is the environment layer. If the first camera recognizes a person, it is initially displayed on the second screen layer of the spherical display screen, and as the person moves, it is displayed on the fourth screen layer of the spherical display screen, and as the person continues to move, it continues to be displayed on the next screen layer belonging to the person layer, until the vehicle exterior monitoring module cannot collect the image information of the person. Through layered display of multiple different types of screen layers, a three-dimensional dynamic display of the vehicle's external image information is achieved.

[0048] In some optional embodiments, when any first camera of the external monitoring module recognizes the presence of foreign objects outside the vehicle, the radar of the monitoring device belonging to the same group as the first camera is activated; when the first camera of the external monitoring module does not recognize the presence of foreign objects outside the vehicle, the radar of the monitoring device belonging to the same group as the first camera is turned off.

[0049] Specifically, when the vehicle is started, the vehicle exterior monitoring module will automatically start, but only the first camera will be started, and whether the radar is started depends on the image information of the vehicle exterior collected by the first camera. Assume that two groups of monitoring devices are set in the front area of ​​the vehicle: monitoring device A and monitoring device B, each monitoring device includes a first camera and a radar. If the first camera in monitoring device B identifies a foreign object from the collected image information, the radar of monitoring device B is started at this time, and the distance between the foreign object and the vehicle is continuously collected. When the first camera in monitoring device B does not identify the foreign object from the collected image information, it indicates that the foreign object may have left the image acquisition range of the first camera of monitoring device B at this time, and the radar of monitoring device B is turned off at this time. If the foreign object enters the image acquisition range of the first camera in monitoring device C in the right side area of ​​the vehicle at this time, the radar in monitoring device C is turned on or off accordingly with reference to the above process. By starting the radar in the same group as the first camera only when the first camera identifies the presence of a foreign object outside the vehicle, energy is saved and the life of the equipment is extended, and when the first camera does not identify the foreign object, the radar is automatically turned off, further reducing energy consumption and improving the overall efficiency of the system.

[0050] In some optional embodiments, the system also includes a data processing module; when the first camera of the external vehicle monitoring module identifies the presence of foreign objects outside the vehicle, the data processing module is used to mark the foreign objects in the image information of all directions outside the vehicle collected by the first camera.

[0051] Specifically, when any first camera of the vehicle exterior monitoring module identifies a foreign object outside the vehicle, the data processing module can mark the foreign object in the form of color, a marking frame, etc., so that the driver pays special attention to the foreign object, helps the driver to discover potential dangers in time, and take measures in advance to avoid accidents. Optionally, other marking methods can also be used, and the embodiments of the present invention are not limited to this.

[0052] In some optional embodiments, when the radar of the external monitoring module detects that the distance between any foreign object and the vehicle is less than a preset threshold, the spherical display screen of the secondary spherical display device is used to display the movement of the foreign object from a horizontal angle; when the radar of the external monitoring module does not detect that the distance between any foreign object and the vehicle is less than a preset threshold, the spherical display screen of the secondary spherical display device is used to display image information of the right side of the vehicle from the horizontal direction of the vehicle.

[0053] Specifically, since the main spherical display device displays a panoramic image of the outside of the vehicle from a bird's-eye view directly above the vehicle, the secondary spherical display device only needs to perform a supplementary display to enable the driver to better understand the environment outside the vehicle. When the first camera recognizes that there is a foreign object outside the vehicle, the radar automatically turns on and continuously collects the distance between the foreign object and the vehicle, and the data processing module also marks the foreign object. Therefore, when the radar detects that the distance between the foreign object and the vehicle is less than a preset threshold, the spherical display screen of the secondary spherical display device will display the movement of the marked foreign object from a horizontal angle, helping the driver to understand the potential dangers in real time and take timely measures to avoid collisions. If the radar detects that the distance between the foreign object and the vehicle is not less than the preset threshold, that is, there may be no risk of collision at this time, and the movement of the foreign object will not continue to be displayed. Taking into account the blind spot that may appear on the right side of the vehicle when overtaking, turning, parking, etc., when the distance between the above-mentioned foreign object and the vehicle is not less than the preset threshold and if all the first cameras do not identify the foreign object, the spherical display screen of the secondary spherical display device will display the image information of the right side of the vehicle, helping the driver to better understand the environment on the right side of the vehicle, reduce blind spots, and further improve driving safety.

[0054] In some optional embodiments, the system further includes a display control switch, and the display control switch is used to control the display of the in-vehicle display module.

[0055] Specifically, since the in-vehicle display module will automatically turn on when the vehicle is started, if the driver does not need to observe the overhead panoramic view outside the vehicle, a display control switch can be set so that the driver can manually control whether the in-vehicle display module is displayed, thereby improving operational convenience and saving energy.

[0056] In some optional embodiments, Figure 5 is a working flow chart of the vehicle exterior monitoring system according to an embodiment of the present invention. Figure 5 As shown, after the vehicle is started, all the first cameras of the external monitoring module are started to collect image information from all directions outside the vehicle. The main spherical display device of the in-vehicle display module displays image information from all directions outside the vehicle from a bird's-eye view directly above the vehicle. At the same time, the main spherical display device determines the position of the driver's eyes according to the second camera, thereby adaptively adjusting the spherical display screen. The secondary spherical display device of the in-vehicle display module displays image information on the right side of the vehicle. If any of the first cameras recognizes that there is a foreign object outside the vehicle, the radar belonging to the same monitoring device group as the first camera is started to collect the distance between the foreign object and the vehicle. It is determined whether the distance is less than a preset threshold. If so, the secondary spherical display device of the in-vehicle display module switches from the image information on the right side of the vehicle to displaying the movement of the foreign object from a horizontal angle.

[0057] The off-vehicle monitoring system provided by the embodiment of the present invention uses multiple groups of monitoring devices arranged around the outside of the vehicle to monitor the outside environment of the vehicle in all directions, that is, the first camera is used to collect image information of all directions outside the vehicle, the radar is used to collect the distance of foreign objects around the vehicle, and the main spherical display device of the in-vehicle display module is used to display the image information of all directions outside the vehicle from a bird's-eye view directly above the vehicle, so that the driver can intuitively see the bird's-eye view around the vehicle, which helps to avoid blind spots and dead angles. The secondary spherical display device of the in-vehicle display module displays the image information of the outside of the vehicle from the horizontal angle of the vehicle, so that the driver can pay attention to the details of the outside of the vehicle, further improving driving safety and driving experience, and is suitable for a variety of driving scenarios.
