[0043] Figure 6 This is a block diagram of an embodiment of a vehicle field of view expansion display device according to the present invention. Detailed Implementation
[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0045] To facilitate understanding of the embodiments of the present invention, further explanations and descriptions will be provided below with reference to the accompanying drawings and specific embodiments. These embodiments do not constitute a limitation on the embodiments of the present invention.
[0046] To facilitate understanding of this embodiment, the vehicle field of view extension display method provided by this invention will be described in detail below. The executing entity is the vehicle control center in the vehicle field of view assistance system, which can be understood as the vehicle controller, such as... Figure 1The diagram shown is a structural schematic of a vehicle vision assistance system. Figure 1 As shown, in addition to the vehicle control center 100 mentioned above, the vehicle vision assistance system also includes a vision acquisition device 101 and a vision display device 102 connected to the vehicle control center 100.
[0047] In actual use, the aforementioned field of view display device 102 is the vehicle control screen, which is generally installed on the right side of the driver's seat for easy viewing and operation by the driver.
[0048] The aforementioned field of vision acquisition device 101 is installed on the vehicle and located in the vehicle's blind spot. The blind spot can be understood as an area that the driver cannot observe through the rearview mirror or an area that frequently needs to be observed by moving the rearview mirror. The field of vision acquisition device can be installed in the aforementioned blind spot to acquire the field of vision image of the blind spot, and the field of vision image is displayed on the field of vision display device 102 through the vehicle control center 100 to eliminate the driver's blind spot.
[0049] For example, while driving, drivers need to check the rear of the vehicle using the rearview mirror. The small size of the rearview mirror results in a small reflected field of view, and its installation position inside the vehicle further reduces the effective field of view. Additionally, the rearview mirror needs to be manually adjusted to suit different driver positions and habits. To facilitate the driver's ability to check the rear of the vehicle, the aforementioned field-of-view acquisition device can be installed on the tailgate. Installing this device effectively expands the rear field of view. Furthermore, the pillars on both sides of the windshield are structural support components present in all vehicles. For the driver, these pillars obstruct the view. Therefore, the aforementioned field-of-view acquisition device can be placed on the upper side of the windshield to eliminate the blind spots caused by the pillars and expand the front field of view.
[0050] Other blind spots can also be eliminated by installing field of view acquisition devices, which will not be elaborated here. The specific installation location and number of field of view acquisition devices can be installed according to actual needs, and there are no restrictions here.
[0051] The following section will detail a method for expanding vehicle field of vision display in conjunction with a vehicle vision assistance system. (See also...) Figure 2 This is a flowchart illustrating an embodiment of a vehicle field-of-view expansion display method provided by an embodiment of the present invention. Figure 2 As shown, the process may include the following steps:
[0052] Step 201: Real-time acquisition of vehicle speed, system resource information, field of view display resolution of the field of view display device, and field of view images sent by the field of view acquisition device;
[0053] The aforementioned field-of-view acquisition device can be a camera to acquire video images, i.e., field-of-view images, in real time. In specific implementation, the field-of-view acquisition device is connected to the vehicle control center via LVDS (Low-Voltage Differential Signaling) hardwire, so that the field-of-view image is transmitted to the vehicle control center via the LVDS hardwire. The vehicle control center can then send the field-of-view image to the field-of-view display device for display. The driver can view the blind spot field of view through the field-of-view image displayed on the field-of-view display device.
[0054] In this embodiment, in order to facilitate the driver's view of blind spots, the field of vision image captured by the aforementioned field of vision acquisition device needs to be displayed continuously during driving to achieve the same requirement as checking the rearview mirror. Since this function is always on, it needs to occupy fixed system resources, which can easily squeeze out the resource usage of other functions in the system, resulting in the shutdown of other functions. This situation greatly reduces the driver's driving experience.
[0055] To solve the above problem, the display frame rate of the field of view image on the field of view display device can be adjusted to avoid the field of view image being displayed at a high display frame rate all the time, which would consume too many system resources.
[0056] In practical use, when the vehicle speed is low, the field of view image captured by the field of view acquisition device changes slowly, and a high display frame rate is not required. When the vehicle speed is high, the field of view image captured by the field of view acquisition device changes rapidly. If the display frame rate is low at this time, the displayed field of view image will appear blurry or stuttering. Therefore, the vehicle speed is a factor affecting the display frame rate.
[0057] A field-of-view display device can be understood as a device that includes the vehicle control screen. Typically, the aforementioned field-of-view image occupies a small, fixed display area on the device. This area can be located in the lower left corner, upper right corner, or center of the device; no specific limitation is made here. When the display area is at its default size, it indicates that the driver is not paying much attention to blind spots, so the field-of-view image can be displayed at a lower frame rate. When the display area is enlarged to fill the screen, meaning the driver is paying more attention to blind spots, the field-of-view image can be displayed at a higher frame rate for easier viewing. The size of the display area can be represented by resolution; a higher resolution indicates a larger display area, and a lower resolution indicates a smaller display area. Therefore, the field-of-view display resolution is also a factor affecting the frame rate.
[0058] In practical use, the aforementioned field-of-view image can be moved, zoomed in, or zoomed out according to the driver's needs to satisfy the driver's viewing requirements. Specifically, it receives operation commands in response to touch operations on the field-of-view image; these operation commands include zoom-in commands, zoom-out commands, or drag commands; and performs corresponding operations on the field-of-view image according to the operation commands. For example, the field-of-view image can be freely dragged with a finger, and it can be zoomed to full screen by clicking, and returned to its original size by clicking again. The specific touch operations performed on the field-of-view image are not limited to the examples shown above, and are not limited here.
[0059] Since the display frame rate has a direct impact on the system resources of the vehicle control center, system resource information is also an influencing factor on the display frame rate. System resource information includes at least the following: CPU (Central Processing Unit) and memory, but may also include GPU (Graphics Processing Unit) and processing threads, etc., without limitation here; CPU, memory, and GPU here refer to the remaining unused system resources.
[0060] In this embodiment, the display frame rate of the field of view image can be adjusted and determined by acquiring three factors in real time: vehicle speed, system resource information, and field of view display resolution.
[0061] Step 202: Determine the display frame rate of the field of view image based on the vehicle speed, system resource information, and field of view display resolution;
[0062] Based on the vehicle speed, system resource information, and field of view display resolution obtained in step 201, the display frame rate of the field of view image is determined in real time to achieve the purpose of adjusting the display frame rate in real time.
[0063] Step 203: At the display frame rate, send the field of view image to the field of view display device for display.
[0064] After determining the display frame rate of the field of view image through step 202, the vehicle control center can obtain the display window on the field of view display device used to display the field of view image, bind the field of view image to the display window for rendering, and finally display the field of view image on the field of view display device through the GPU at the real-time determined display frame rate, so that the driver can view it.
[0065] This invention provides a vehicle field of vision expansion display method, applicable to the vehicle control center in a vehicle vision assistance system. The system further includes a field of vision acquisition device and a field of vision display device connected to the vehicle control center. The field of vision acquisition device is installed on the vehicle and located in the vehicle's blind spot. The method includes: acquiring in real-time the vehicle's speed, system resource information, the field of vision display resolution of the field of vision display device, and the field of vision image sent by the field of vision acquisition device; determining the display frame rate of the field of vision image based on the vehicle speed, system resource information, and field of vision display resolution; and sending the field of vision image to the field of vision display device for display at the specified frame rate. This invention utilizes a field of vision acquisition device to acquire a field of vision image at the blind spot location and then dynamically displays the image on the field of vision display device for the driver to view. This method of expanding the driver's field of vision by installing a field of vision acquisition device in the vehicle effectively eliminates blind spots, thereby ensuring safe driving.
[0066] In addition, the display frame rate of the field of view image can be dynamically adjusted based on the vehicle's speed, system resource information, and field of view display resolution. This ensures that the field of view image is displayed at the adjusted frame rate, effectively avoiding the problem of the field of view image being displayed at a high frame rate all the time, which would consume too many system resources and cause other functions to be disabled. This method of reducing system resource consumption by adjusting the display frame rate can greatly improve the driver's driving experience.
[0067] In one implementation, step 202 above can be specifically achieved through steps A1 to A2:
[0068] Step A1: Find the target specific display frame rate that matches the vehicle speed, system resource information, and field of view display resolution from the display frame rate lookup table;
[0069] Step A2: Determine the target-specific display frame rate as the display frame rate of the field-of-view image.
[0070] The display frame rate lookup table pre-stores multiple calibrated specific display frame rates, along with query information matching each specific display frame rate. The query information includes vehicle speed, system resource information, and field-of-view display resolution. For ease of understanding, taking system resource information including CPU and memory as an example, Table 1 shows an example of a display frame rate lookup table, as shown in Table 1:
[0071] Table 1
[0072]
[0073] It should be noted that Table 1 only shows an example of the correspondence between query information and a specific display frame rate. The specific correspondence between query information and a specific display frame rate can be set according to actual needs, and is not limited here.
[0074] For example, a vehicle speed of 70, CPU usage of 60, memory usage of 55, and a field of view display resolution of 4K correspond to the vehicle speed [60-79], CPU usage [60%-79%], memory usage [55-74], and field of view display resolution [2K / 4K] in the query information. Therefore, the determined display frame rate of the field of view image is 50, that is, the field of view image is displayed on the field of view display device at 50 frames per second.
[0075] Drivers don't always pay attention to and check blind spots in all driving scenarios. Therefore, to further conserve system resources, a hardware button can be added to turn the field of vision image on and off, controlling whether it's displayed on the display device. Figure 3 As shown, the aforementioned vehicle vision assistance system also includes a first function button 300 connected to the vehicle control center 100. The first function button 300 is installed on the vehicle's steering wheel so that the driver can manually control whether the vision image is displayed by clicking it.
[0076] In actual use, the first function button can also be a touchable function control that achieves the above functions. This function control is deployed on the vehicle control screen of the vision display device. The form of the first function button is not limited here, as long as it can achieve the above functions.
[0077] Based on the aforementioned first function button. Figure 4 A flowchart illustrating an embodiment of another vehicle field-of-view display method is shown. For example... Figure 4 As shown, the process may include the following steps:
[0078] Step 401: Real-time acquisition of vehicle speed, system resource information, field of view display resolution of the field of view display device, and field of view images sent by the field of view acquisition device;
[0079] Step 402: Determine the display frame rate of the field of view image based on the vehicle speed, system resource information, and field of view display resolution;
[0080] The processes of steps 401 to 402 above can be referred to steps 201 to 202, and are not limited here.
[0081] Step 403: Receive the control command corresponding to the control operation on the first function button;
[0082] Step 404: Determine whether the control command is a display command;
[0083] Since the on / off state of the aforementioned field of view image display is integrated into the first function button, the driver's operation of the first function button can generate a control command to turn on the field of view image display, or it can generate a control command to turn off the field of view image display based on the control operation. The control operation corresponding to turning on the field of view image display is a single-click operation, that is, the driver clicks the first function button once to turn on the field of view image display. The control operation corresponding to turning off the field of view image display is a multi-click operation, that is, the driver clicks the first function button two or three times to turn off the field of view image display. Since the control commands are different depending on the control operation, the vehicle control center needs to determine whether the control command is a display command, that is, a command for the field of view display device to display the field of view image, after receiving the control command. If the control command is determined to be a display command, step 405 is executed; if the control command is determined not to be a display command, the field of view image is not displayed on the field of view display device.
[0084] In this embodiment, the above control operations are not limited and can be set according to actual needs.
[0085] Step 405: If it is determined that the control command is a display command, the field of view image is sent to the field of view display device for display at the display frame rate.
[0086] The vehicle field of view expansion display method provided in this application embodiment can control the display or non-display of the field of view image of the blind spot collected by the field of view acquisition device on the field of view display device according to the driver's needs by controlling the operation of the first function button, thereby meeting the driver's needs.
[0087] In practical use, different driving postures during vehicle operation result in varying blind spots for the driver. In this embodiment, the blind spots can be eliminated by adjusting the direction and angle of the vision acquisition device. Specifically, the vehicle vision assistance system also includes an adjustment device connected to the vehicle control center. The vision acquisition device is mounted on the vehicle via the adjustment device, meaning the vehicle control center adjusts the direction and angle of the vision acquisition device by driving the adjustment device to rotate. Based on the above description, Figure 5 A flowchart illustrating an embodiment of another vehicle field-of-view display method is shown. For example... Figure 5 As shown, the process may include the following steps:
[0088] Step 501: Obtain the steering angle information of the vehicle's steering wheel;
[0089] Steering angle information includes the steering direction information of the steering wheel and the steering wheel rotation angle information.
[0090] Step 502: Determine the adjustment direction angle information of the field of view acquisition device based on the steering angle information;
[0091] Similarly, the adjustment direction and angle information includes adjustment direction information and adjustment angle information.
[0092] The specific process for determining the adjustment direction angle information is as follows: search the direction angle lookup table for target-specific adjustment direction angle information that matches the steering angle information; and determine the target-specific adjustment direction angle information as the adjustment direction angle information of the field of view acquisition device.
[0093] The direction angle lookup table stores multiple different specific adjustment direction angles, as well as the specific steering angle information corresponding to each specific adjustment direction angle. For ease of understanding, an example of the direction angle lookup table is shown in Table 2:
[0094] Table 2
[0095]
[0096] It should be noted that Table 2 only shows an example of the correspondence between specific steering angle information and specific adjustment direction angle information. The specific correspondence between specific steering angle information and specific adjustment direction angle information can be set according to actual needs, and is not limited here.
[0097] The corresponding adjustment direction angle information can be obtained by looking up the steering wheel steering angle information in Table 2.
[0098] Step 503: Generate adjustment instructions corresponding to the adjustment direction and angle information;
[0099] Step 504: Send the adjustment command to the adjustment device to drive the adjustment device to move the field of view acquisition device to the direction angle corresponding to the adjustment direction angle information;
[0100] The aforementioned adjustment device is a rotatable device. In actual use, in addition to using the adjustment device to drive the field of view acquisition device to rotate, an angle-adjustable field of view acquisition device can also be used to achieve the same result, which will not be described in detail here.
[0101] In practical use, in addition to determining the adjustment direction angle based on the steering wheel's steering angle information, a second function button connected to the vehicle control center can be installed on the steering wheel to facilitate driver control operations as needed. This second function button can include directional buttons for up, down, left, and right. The direction information is determined by controlling these buttons, and the adjustment angle is determined by the number of times the buttons are pressed. For example, each press adjusts the angle by 5 degrees, and two presses adjust it by 10 degrees. The specific number of presses and the adjustment angle can be set according to requirements and are not limited here.
[0102] The aforementioned second function button can also be a touch-sensitive function control deployed on the vehicle control screen of the field of view display device, so that the adjustment direction angle information can be determined by touching the function control. The form of the second function button is not limited here, as long as it can achieve the above-mentioned function.
[0103] In step 505 below, the field of vision image acquired by the vehicle control center is acquired by the field of vision acquisition device under the direction angle corresponding to the adjusted direction angle information. This method of adjusting the direction angle of the field of vision acquisition device in real time can effectively eliminate the problem of blind spots that cause safety hazards to driving under different driving postures of the vehicle, and ensure the driver's safe driving.
[0104] Step 505: Real-time acquisition of vehicle speed, system resource information, field of view display resolution of the field of view display device, and field of view images sent by the field of view acquisition device;
[0105] Step 506: Determine the display frame rate of the field of view image based on the vehicle speed, system resource information, and field of view display resolution;
[0106] Step 507: At the display frame rate, send the field of view image to the field of view display device for display.
[0107] The processes of steps 505 to 507 above can be referred to the processes of steps 201 to 203, and will not be repeated here.
[0108] See Figure 6 This is a block diagram illustrating an embodiment of a vehicle field of view extension display device provided by the present invention. The device is suitable for a vehicle control center within a vehicle vision assistance system. The vehicle vision assistance system also includes a field of view acquisition device and a field of view display device connected to the vehicle control center. The field of view acquisition device is installed on the vehicle and located in the vehicle's blind spot. Figure 6 As shown, the device may include:
[0109] The acquisition module 601 is used to acquire in real time the vehicle's driving speed, system resource information, field of view display resolution of the field of view display device, and field of view images sent by the field of view acquisition device;
[0110] The determination module 602 is used to determine the display frame rate of the field of view image based on the vehicle speed, system resource information and field of view display resolution;
[0111] Display module 603 is used to send the field of view image to the field of view display device for display at the display frame rate.
[0112] This invention provides a vehicle field of vision extension display device, which is applicable to the vehicle control center in a vehicle vision assistance system. The vehicle vision assistance system also includes a field of vision acquisition device and a field of vision display device connected to the vehicle control center. The field of vision acquisition device is installed on the vehicle and located in the vehicle's blind spot. The device includes: real-time acquisition of the vehicle's speed, system resource information, the field of vision display resolution of the field of vision display device, and the field of vision image sent by the field of vision acquisition device; determining the display frame rate of the field of vision image based on the vehicle speed, system resource information, and field of vision display resolution; and sending the field of vision image to the field of vision display device for display at the specified frame rate. This invention utilizes the field of vision acquisition device to acquire field of vision images from the blind spot location and then dynamically displays these images on the field of vision display device for the driver to view. This method of expanding the driver's field of vision by installing a field of vision acquisition device in the vehicle effectively eliminates the driver's blind spot, thereby ensuring safe driving.
[0113] In addition, the display frame rate of the field of view image can be dynamically adjusted based on the vehicle's speed, system resource information, and field of view display resolution. This ensures that the field of view image is displayed at the adjusted frame rate, effectively avoiding the problem of the field of view image being displayed at a high frame rate all the time, which would consume too many system resources and cause other functions to be disabled. This method of reducing system resource consumption by adjusting the display frame rate can greatly improve the driver's driving experience.
