Description

Technical Field

[0001] This application relates to the field of automotive image control technology, specifically to a 360° image opening / closing method, device, equipment, and storage medium. Background Technology

[0002] Currently, 360° panoramic imaging for automobiles is an important driver assistance technology that uses an in-vehicle display screen to view real-time images of the vehicle's surroundings in a 360° panoramic manner, with an ultra-wide field of view and seamless stitching. It helps drivers see blind spots around the vehicle and improves driving safety.

[0003] In related technologies, the common methods for activating and deactivating 360-degree automotive imaging systems mainly fall into two categories:

[0004] The first type of 360-degree camera system activates and deactivates when the vehicle turns, using a combination of turn signals, vehicle speed, and gear position. Specifically, when the driver moves the turn lever, triggering the turn signal, the 360-degree camera on the corresponding side of the vehicle activates (displaying the image of the turning side) when the vehicle speed is below a certain low setting (usually 10 km / h); then, when the vehicle speed exceeds a certain high setting (usually 25 km / h), the 360-degree camera on the corresponding side of the vehicle deactivates; if the vehicle does not reach the high setting, the 360-degree camera on the corresponding side of the vehicle deactivates when the vehicle is disengaged from Drive (D).

[0005] The second method involves manually controlling the 360-degree camera system to turn on and off while the vehicle is moving forward, based on the vehicle's speed. Specifically, while the vehicle is moving forward, the driver attempts to activate the 360-degree camera system via a button or voice command. When the vehicle speed is below a set high threshold, the 360-degree camera system activates (displaying a 360-degree view), and then the driver steers. Afterward, when the vehicle speed exceeds the set high threshold, the 360-degree camera system automatically deactivates. When the vehicle speed is below the set high threshold, the 360-degree camera system can also be deactivated manually or via voice command, or when the vehicle is shifted out of Drive (D) gear.

[0006] However, the first method of activating and deactivating the 360-degree camera system has the following drawbacks: ① It is speed-dependent, only triggering at extremely low speeds during cornering. If a turn signal is triggered, the 360-degree camera will not activate if the vehicle speed exceeds a certain set value (usually 25 km / h), failing to meet the imaging needs during high-speed cornering. ② After cornering, if the vehicle continues to travel at low speed, the 360-degree camera will only automatically deactivate after disengaging from Drive (D). This occupies the navigation, music, and video interfaces on the central control screen. Otherwise, the user must manually deactivate it, lacking flexibility and intelligence.

[0007] The second method of turning on and off the car 360-degree camera has the following drawbacks: the 360-degree camera cannot meet the user's need to view the 360-degree camera to supplement blind spots when the vehicle is traveling at a speed greater than a set high threshold and the user wants to change lanes. Summary of the Invention

[0008] This application provides a method, apparatus, device, and storage medium for opening and closing 360-degree images, which solves the problems of not being able to open 360-degree images under high-speed conditions and the 360-degree images not exiting in a timely manner.

[0009] In a first aspect, embodiments of this application provide a 360° image activation / deactivation method, the method comprising the following steps:

[0010] The steering lever triggers a steering signal;

[0011] After receiving the turn signal, the forward radar identifies the area ahead. If there is an obstacle, it calculates the distance between the vehicle and the obstacle. At any vehicle speed, if there is no obstacle in front or the distance between the vehicle and the obstacle is greater than the instantaneous speed distance, the 360-degree camera is activated.

[0012] After the vehicle completes a turn, if the maximum steering wheel rotation angle is less than the set small angle threshold and the radars on both sides detect no obstacles, the 360-degree camera will continue to operate for a first set time period and then automatically turn off. If the maximum steering wheel rotation angle is greater than the set large angle threshold and the radars on both sides detect no obstacles, the steering wheel will return to center and the 360-degree camera will automatically turn off.

[0013] In conjunction with the first aspect, in one implementation, when the steering wheel is straightened and the left and right side radars detect obstacles, the 360-degree camera continues to be activated until the left and right side radars detect no obstacles, at which point the 360-degree camera automatically turns off.

[0014] In conjunction with the first aspect, in one implementation, when the maximum rotation angle of the steering wheel is less than a set small angle threshold and the left and right side radars detect obstacles, the 360-degree camera continues to be activated until the left and right side radars detect no obstacles, and then the 360-degree camera automatically turns off after a second set time period.

[0015] In conjunction with the first aspect, in one embodiment, the vehicle steering includes changing lanes left and right, turning left and right, and making a U-turn; the set small angle threshold is equal to 15°, and after the vehicle steering is completed, when the maximum rotation angle of the steering wheel is less than 15°, the vehicle steering is a lane change; the set large angle threshold is equal to 80°, and after the vehicle steering is completed, when the maximum rotation angle of the steering wheel is greater than 80°, the vehicle steering is a left or right turn or a U-turn.

[0016] In conjunction with the first aspect, in one implementation, when the left and right radars detect an obstacle for more than a third set time period, the left and right radars obtain information from the navigation system as to whether they have entered a congested section of road. If so, the automatic shutdown time of the 360-degree image is delayed to a fourth set time period.

[0017] Secondly, embodiments of this application provide a 360° image opening / closing device, comprising:

[0018] Steering signal receiving module, used to receive steering signals from steering levers;

[0019] The radar ranging module is used to receive feedback signals from the radars in front, behind, left, and right.

[0020] The steering wheel angle recognition module is used to identify the maximum steering angle of the steering wheel in a single turn.

[0021] Vehicle speed recognition module, used to obtain vehicle speed;

[0022] The on / off module is used to activate the 360-degree camera system when the steering signal receiving module acquires a steering signal, the radar ranging module determines that there is no obstacle ahead based on the feedback signal, or the distance between the vehicle and the obstacle ahead is greater than the instantaneous speed distance corresponding to the vehicle speed. It is also used to deactivate the 360-degree camera system after a first set time period when the maximum steering angle is less than a set small angle threshold and the radars on both sides detect no obstacles, after the vehicle has completed a turn. When the maximum steering angle is greater than a set large angle threshold and the radars on both sides detect no obstacles, the steering wheel is returned to center, and the on / off module deactivates the 360-degree camera system.

[0023] In conjunction with the second aspect, in one embodiment, the opening and closing module is further configured to keep the 360-degree image continuously on when the steering wheel is straightened and the left and right radars detect obstacles, until the radar ranging module determines that the left and right radars detect no obstacles, and then the opening and closing module closes the 360-degree image.

[0024] In conjunction with the second aspect, in one embodiment, the opening and closing module is further configured to continue to activate the 360-degree image when the maximum rotation angle of the steering wheel is less than a set small angle threshold and the left and right radars identify obstacles, until the radar ranging module determines that the left and right radars identify no obstacles based on the left and right radars, and then the opening and closing module deactivates the 360-degree image after a second set time interval.

[0025] Thirdly, this application provides a 360° image opening / closing device, which includes a processor, a memory, and a 360° image opening / closing program stored in the memory and executable by the processor. When the 360° image opening / closing program is executed by the processor, it implements the steps of the 360° image opening / closing method described above.

[0026] Fourthly, embodiments of this application provide a computer-readable storage medium storing a 360° image activation / deactivation program, wherein when the 360° image activation / deactivation program is executed by a processor, it implements the steps of the aforementioned 360° image activation / deactivation method.

[0027] The beneficial effects of the technical solutions provided in this application include at least the following:

[0028] 1. The 360-degree camera activation / deactivation method of this application only requires receiving a turn signal and confirming a safe turning distance (no obstacles ahead or a distance greater than the instantaneous vehicle speed distance) to activate the 360-degree camera. This method is not affected by vehicle speed and can be activated at any speed, solving the problem of existing technologies failing to activate the 360-degree camera to compensate for blind spots at high speeds. Simultaneously, when the maximum steering wheel rotation angle is less than a set small angle threshold, indicating a lane change, if the left and right radars detect no obstacles, the 360-degree camera continues to operate for a first set time period before automatically deactivating. The 360-degree camera of this application… The opening and closing method, which shuts off the 360-degree camera according to a first set time period, solves the problem that the 360-degree camera cannot exit in time if the vehicle is at a low speed after a lane change. When the maximum steering wheel rotation angle is greater than the set large angle threshold, it indicates that the vehicle is turning left or right or making a U-turn. If the radars on both sides detect no obstacles, the steering wheel is straightened and the 360-degree camera automatically shuts off. The 360-degree camera opening and closing method of this application uses the straightening of the steering wheel as the condition for shutting off the 360-degree camera, which solves the problem that the 360-degree camera cannot exit in time after turning left or right or making a U-turn. The 360-degree camera opening and closing method of this application, through reasonable design, exits the 360-degree camera in time, avoids occupying the central control screen for a long time, and is more intelligent and flexible.

[0029] 2. In the 360° camera opening and closing device of this application, after receiving a turning signal, the turning signal receiving module confirms that there is a safe turning distance (no obstacles ahead or the distance to the obstacle is greater than the instantaneous vehicle speed distance), and then activates the 360° camera. The 360° camera opening and closing device is not affected by vehicle speed and can be activated at any vehicle speed. At the same time, the steering wheel angle recognition module identifies the maximum steering angle of the steering wheel in a single turn. Based on different maximum steering angles, the opening and closing module adopts different strategies to close the 360° camera. When the maximum steering wheel rotation angle is less than a set small angle threshold, it indicates that the vehicle is changing lanes. If the left and right radars identify no obstacles at this time, the 360° camera continues to be activated for a first set time period, and then the opening and closing module closes the 360° camera. The 360° camera opening and closing method of this application closes according to the first set time period, which solves the problem that the 360° camera cannot exit in time if the vehicle is at a low speed after changing lanes. When the maximum rotation angle of the steering wheel is greater than the set large angle threshold, it indicates that the vehicle is turning left or right or making a U-turn. At this time, if the radars on both sides identify no obstacles, the steering wheel returns to center and the opening and closing module shuts down the 360-degree image. The 360-degree image opening and closing device of this application uses the steering wheel returning to center as the condition for shutting down the 360-degree image, which solves the problem of not being able to exit in time after turning left or right or making a U-turn.

[0038] To make the purpose, technical solution, and advantages of this application clearer, the following will be described in conjunction with the appendix. Figure 1 The embodiments of this application will be described in further detail.

[0039] In a first aspect, embodiments of this application provide a 360° image activation / deactivation method.

[0040] In one embodiment, reference is made to Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the 360° image activation / deactivation method of this application. Figure 1 As shown, the 360 ​​image activation / deactivation methods include:

[0041] S1. The steering lever triggers a steering signal.

[0042] S2. After receiving the turn signal, the forward radar identifies the area ahead. If there is an obstacle, it calculates the distance between the vehicle and the obstacle. At any vehicle speed, if there is no obstacle ahead or the distance between the vehicle and the obstacle is greater than the instantaneous speed distance, the 360-degree camera is activated.

[0043] The instantaneous speed distance is the distance between vehicles measured in km / h, expressed in meters. For example, if the instantaneous speed is 10 km / h, the instantaneous speed distance is 10 meters. The instantaneous speed distance is used as a benchmark to determine whether a safe turning distance is possible.

[0044] It's worth noting that the 360-degree camera can be activated at any vehicle speed, provided there is a safe turning distance. Unlike existing technologies, which cannot activate the 360-degree camera at high speeds, this solves the problem of the 360-degree camera not being able to be activated under high-speed conditions.

[0045] S3. After the vehicle completes a turn, the system first identifies the maximum steering wheel rotation angle. If the maximum steering wheel rotation angle is less than the set small angle threshold, it indicates the vehicle is changing lanes. If the left and right side radars detect no obstacles, the 360-degree camera will remain on for a first set time period and then automatically turn off. If the maximum steering wheel rotation angle is greater than the set large angle threshold, it indicates the vehicle is turning left or right or making a U-turn. If the left and right side radars detect no obstacles, the steering wheel will return to center, and the 360-degree camera will automatically turn off. Returning the steering wheel to center means returning it to zero degrees.

[0046] The small-angle threshold is set based on the steering wheel angle in actual lane-changing scenarios. The large-angle threshold is set based on the steering wheel angle in actual left / right turns and U-turns.

[0047] When changing lanes, if the steering wheel angle is small, less than the set small angle threshold, the 360-degree camera will automatically turn off after the lane change is completed and the camera has been on for a first set period of time. When turning left or right or making a U-turn, if the steering wheel angle is large, greater than the set large angle threshold, the steering wheel will return to center and the 360-degree camera will automatically turn off.

[0048] Specifically, when the 360-degree camera is activated, the activation range is the same as that of a regular 360-degree camera. That is, when driving straight, the full-range camera is activated; when turning, the corresponding side camera is activated (left-side camera for left turns, right-side camera for right turns).

[0049] The 360-degree camera activation and deactivation method of this application only needs to confirm a safe turning distance (no obstacles in front or the distance to the obstacle is greater than the instantaneous vehicle speed distance) after receiving a turning signal to activate the 360-degree camera. The 360-degree camera activation and deactivation method of this application is not affected by vehicle speed and can be activated at any vehicle speed, which solves the problem that the existing technology cannot activate the 360-degree camera to supplement blind spots at high speeds.

[0050] Meanwhile, when the maximum steering wheel rotation angle is less than the set small angle threshold, it indicates that the vehicle is changing lanes. If the left and right radars identify no obstacles at this time, the 360-degree image will continue to be turned on for the first set time period and then automatically turn off. The 360-degree image activation and deactivation method of this application turns off according to the first set time period, which solves the problem that the 360-degree image cannot be deactivated in time if the vehicle is at a low speed after changing lanes.

[0051] When the maximum rotation angle of the steering wheel is greater than the set large angle threshold, it indicates that the vehicle is turning left or right or making a U-turn. If the radars on both sides detect no obstacles, the steering wheel returns to center and the 360-degree camera automatically turns off. The 360-degree camera activation and deactivation method of this application uses the steering wheel returning to center as the condition for turning off the 360-degree camera, which solves the problem of not being able to exit in time after turning left or right or making a U-turn.

[0052] The 360° camera activation / deactivation method of this application, through reasonable design, allows for timely exit of the 360° camera, avoiding prolonged occupation of the central control screen, making it more intelligent and flexible.

[0053] Furthermore, in one embodiment, when the steering wheel is straightened and the radars on both sides detect obstacles, the 360-degree camera remains on until the radars on both sides detect no obstacles, at which point the 360-degree camera automatically turns off.

[0054] It is worth noting that obstacles on the left and right sides will prolong the opening time; however, obstacles in front will not prolong the time. This is because the front is not a blind spot, so there is no need to use the 360-degree camera to supplement the field of vision, and it is also to avoid occupying the central control screen when there is a risk of collision.

[0055] In this embodiment, when the steering wheel is straightened during left and right turns and U-turns, but the radars on both sides detect obstacles, the 360-degree camera's activation time is appropriately extended until the radars on both sides detect no obstacles, at which point the 360-degree camera automatically turns off. This extends the time needed to supplement the field of vision and further ensures steering safety.

[0056] Furthermore, in one embodiment, when the maximum rotation angle of the steering wheel is less than a set small angle threshold and the radars on both sides detect obstacles, i.e., in a scenario where there are obstacles after changing lanes, the 360-degree camera continues to be turned on until the radars on both sides detect no obstacles. After that, the 360-degree camera automatically turns off after a second set time interval.

[0057] Preferably, the second set time period is 5 seconds. After the left and right radars identify no obstacles, the 360-degree image automatically turns off after a 5-second delay.

[0058] In this embodiment, when the radars on both sides detect obstacles in a lane change scenario, the activation time of the 360-degree image is appropriately extended until the radars on both sides detect no obstacles. Then, the activation time is extended by a second set time period, and the 360-degree image is automatically turned off. This setting is designed for lane change scenarios with obstacles on both sides, which can extend the supplementary field of view and further ensure steering safety.

[0059] Specifically, the radars on both the left and right sides identify whether there are obstacles. Based on the pre-set left and right safety distances, they determine whether an obstacle is an obstacle. If the obstacle is within the left and right safety distances, it is identified as an obstacle, and the 360-degree image display time is appropriately extended to supplement the field of view. If the obstacle is outside the left and right safety distances, it is not identified as an obstacle. Among them, vehicles traveling side by side in the middle of adjacent lanes are not identified as obstacles.

[0060] Furthermore, in one embodiment, vehicle steering includes changing lanes left and right, turning left and right, and making a U-turn.

[0061] The small angle threshold is set to 15°. When the maximum rotation angle of the steering wheel is less than the set small angle threshold, the vehicle will turn to change lanes to the left or right.

[0062] The maximum steering angle threshold is set to 80°. When the maximum steering wheel rotation angle is greater than the set maximum steering angle threshold, the vehicle will turn left or right or make a U-turn.

[0063] Specifically, when changing lanes, the steering wheel rotation angle is generally between 3 and 10 degrees. More specifically, the steering wheel rotation angle varies depending on the vehicle speed. When the speed is higher, the steering wheel rotation should be smaller, usually between 3 and 5 degrees; while when the speed is lower, the steering wheel rotation can be appropriately increased, generally between 5 and 10 degrees.

[0064] When making a U-turn, the steering wheel usually needs to be rotated more than 90 degrees and adjusted to half a turn so that the front of the car is aligned with the center of the road.

[0065] When a vehicle turns left or right, the steering wheel rotation angle varies depending on factors such as the turning radius and vehicle speed. However, the rotation angles for left and right turns are usually similar, generally between 90 and 180 degrees. Small radius turns: On narrow roads or when a quick U-turn is needed, the steering wheel may need to rotate close to 180 degrees or more. Large radius turns: When turning on wide roads or highways, the steering wheel rotation angle may only need to be around 90 degrees.

[0066] Furthermore, in one embodiment, when the left and right radars detect an obstacle for more than a third set time period, the left and right radars obtain information from the navigation system as to whether they have entered a congested section. If so, the automatic shutdown time of the 360-degree image is delayed to a fourth set time period.

[0067] Preferably, the fourth set time period is 30 seconds. When the left and right radars obtain information from the navigation system that the vehicle has entered a congested section of road, the time for the 360-degree image to automatically turn off is delayed by 30 seconds.

[0068] In this embodiment, the left and right radars obtain information from the navigation system that the vehicle has entered a congested section of road, and the time for the 360-degree image to automatically turn off is delayed, which can adapt to the road scene and supplement the field of vision for a long time.

[0069] Secondly, embodiments of this application also provide a 360° image opening and closing device.

[0070] In one embodiment, reference is made to Figure 2 , Figure 2 This is a functional module diagram of an embodiment of the 360° image opening and closing device of this application. Figure 2 As shown, the 360-degree image opening and closing device includes:

[0071] Steering signal receiving module, used to receive steering signals from steering levers;

[0072] The radar ranging module is used to receive feedback signals from the radars in front, behind, left, and right; the feedback signals include whether there are obstacles, and if so, the distance to the obstacles.

[0073] The steering wheel angle recognition module is used to identify the maximum steering angle of the steering wheel in a single turn; where a single turn refers to the process from zero degrees back to zero degrees, the steering wheel angle recognition module identifies the maximum steering angle in this process;

[0074] Vehicle speed recognition module, used to obtain vehicle speed;

[0075] The opening and closing module is used to activate the 360-degree camera system when the steering signal receiving module acquires a steering signal, the radar ranging module determines that there is no obstacle ahead based on the feedback signal, or the distance between the vehicle and the obstacle ahead is greater than the instantaneous speed distance corresponding to the vehicle speed. Specifically, the 360-degree camera system can be activated at any vehicle speed, as long as there is a safe distance for steering. Unlike existing technologies, which cannot activate the 360-degree camera system at high speeds, this solves the problem of the inability to activate the 360-degree camera system under high-speed conditions.

[0076] The opening and closing module is also used to, after the vehicle has completed a turn, when the maximum turning angle is less than a set small angle threshold and the radars on both sides detect no obstacles, it indicates that the vehicle is changing lanes and there are no obstacles on the left and right sides. After the 360-degree camera continues to be on for a first set time period, the opening and closing module turns off the 360-degree camera. When the maximum turning angle is greater than a set large angle threshold and the radars on both sides detect no obstacles, it indicates that the vehicle is turning left or right or making a U-turn and there are no obstacles on the left and right sides. The steering wheel is returned to center and the opening and closing module turns off the 360-degree camera.

[0077] The 360° camera opening and closing device of this application, after receiving the turning signal, confirms that there is a safe distance for turning (no obstacles in front or the distance between the camera and the obstacle is greater than the instantaneous vehicle speed distance), and then activates the 360° camera. The 360° camera opening and closing device is not affected by the vehicle speed image and can activate the 360° camera at any vehicle speed.

[0078] Simultaneously, the steering wheel angle recognition module identifies the maximum steering angle of a single turn. Based on different maximum steering angles, the opening and closing module employs different strategies to shut down the 360-degree camera. When the maximum steering wheel rotation angle is less than a set small angle threshold, it indicates that the vehicle is changing lanes. If the left and right radars detect no obstacles, the 360-degree camera continues to operate for a first set time period before the opening and closing module shuts it down. This application's 360-degree camera opening and closing method shuts down the camera according to the first set time period, solving the problem that the 360-degree camera cannot exit in time if the vehicle is at a low speed after a lane change. When the maximum steering wheel rotation angle is greater than a set large angle threshold, it indicates that the vehicle is turning left or right or making a U-turn. If the left and right radars detect no obstacles, the steering wheel returns to center, and the opening and closing module shuts down the 360-degree camera. This application's 360-degree camera opening and closing device uses steering wheel centering as the condition for shutting down the 360-degree camera, solving the problem that the camera cannot exit in time after turning left or right or making a U-turn.

[0079] Furthermore, in one embodiment, the opening and closing module is also used to keep the 360-degree image on when the steering wheel is straightened and the left and right radars identify obstacles, until the radar ranging module determines that the left and right radars identify no obstacles, and then the opening and closing module closes the 360-degree image.

[0080] In this embodiment, when the steering wheel is straightened during left and right turns and U-turns, but the radars on both sides detect obstacles, the 360-degree camera's activation time is appropriately extended until the radars on both sides detect no obstacles. The 360-degree camera is then deactivated by the on / off module, which extends the supplementary field of view and further ensures steering safety.

[0081] Furthermore, in one embodiment, the opening and closing module is also used to keep the 360-degree image on when the maximum rotation angle of the steering wheel is less than a set small angle threshold and the left and right radars identify obstacles, until the radar ranging module determines that the left and right radars identify no obstacles based on the left and right radars, and then the opening and closing module closes the 360-degree image after a second set time interval.

[0082] In this embodiment, when the radars on both sides detect obstacles in a lane change scenario, the activation time of the 360-degree image is appropriately extended until the radars on both sides detect no obstacles. Then, the activation time is extended by a second set time period, and the 360-degree image is turned off by the on / off module.
