[0032] Example 1
[0033] Figure 1 The flowchart of an electronic rearview mirror control method provided in Embodiment 1 of the present invention is applicable to situations where the vehicle rearview mirror is automatically adjusted in real time based on the image captured by the rearview mirror and the current driving status of the vehicle. The method can be executed by an electronic rearview mirror control device, which can be implemented in hardware and / or software and can be configured in an electronic device.
[0034] like Figure 1 As shown, the electronic rearview mirror control method provided in this embodiment may include:
[0035] S110: Obtain current vehicle driving status information and rearview mirror images collected by the electronic rearview mirror.
[0036] In this embodiment, the vehicle driving status information can reflect whether the vehicle is currently driving normally, reversing, or parked. For example, vehicle gear information and vehicle driving direction information; the rearview mirror image is an image collected by the electronic rearview mirror that can reflect the situation around the vehicle. For example, it includes images of the vehicle wheels and the road near the vehicle.
[0037] Specifically, information such as vehicle gear position and driving direction can be collected to reflect the vehicle's driving status. This information can be analyzed to determine whether the vehicle is in reverse, driving normally, or parked. For example, if the vehicle is currently in reverse gear and moving in reverse direction, the analysis will show that the vehicle is currently in reverse. Additionally, rearview mirror images of the vehicle's surroundings can be acquired. The image acquisition period of the electronic rearview mirror can be set, for example, 60 frames per second.
[0038] S120. When the rearview mirror image and the current vehicle driving status information meet the trigger adjustment conditions, determine the standard visual area of the electronic rearview mirror.
[0039] In this embodiment, the standard visual area can be pre-set or input by the user, which is the range of viewing angles that the electronic rearview mirror should have when the vehicle is in a certain driving state.
[0040] Specifically, the system can analyze the images of the vehicle's surroundings captured by the electronic rearview mirror and the current vehicle driving status information to determine whether the rearview mirror image and the current vehicle driving status information meet the trigger adjustment conditions for rearview mirror adjustment, and whether the vehicle currently needs to adjust the electronic rearview mirror viewing angle. When the trigger adjustment conditions are met, the standard visual area of the electronic rearview mirror corresponding to the current vehicle driving status is determined.
[0041] S130. Adjust the visual area of the electronic rearview mirror to the standard visual area.
[0042] Specifically, when it is determined that the viewing angle of the electronic rearview mirror needs to be adjusted, a control adjustment method can be used to adjust the visual area of the electronic rearview mirror until it is adjusted to the standard visual area of the vehicle under the current state. For example, PID control is used to realize multi-loop positive and negative feedback control to adjust the viewing angle of the rearview mirror during the automatic control process, and PLC control, which introduces microelectronics technology, computer technology, automatic control technology and communication technology on the basis of traditional sequential controller, establishes a flexible remote control system to adjust the viewing angle of the rearview mirror.
[0043] The technical solution provided by this invention obtains the current vehicle driving status information and the rearview mirror image collected by the electronic rearview mirror. When the rearview mirror image and the current vehicle driving status information meet the trigger adjustment conditions, the standard visual area of the electronic rearview mirror is determined and the visual area of the electronic rearview mirror is adjusted to the standard visual area. This realizes the rapid determination of the standard visual area of the current vehicle driving status and the real-time automatic adjustment of the electronic rearview mirror, thereby improving the safety of the vehicle driving process.
[0044] Based on the above embodiments, obtaining current vehicle driving status information includes at least one of the following:
[0045] Collect the vehicle's current gear information as the vehicle's current driving status information;
[0046] Collect the vehicle's direction of motion as current vehicle driving status information;
[0047] The vehicle's speed is collected as information about the vehicle's current driving status.
[0048] Specifically, when acquiring current vehicle driving status information, a gear information sensor can be used to collect information such as the vehicle's current parking gear, reverse gear, and drive gear; a direction information sensor can be used to collect information such as the vehicle's forward and reverse movement direction; and a speed information sensor can be used to collect information such as the vehicle's specific speed. At least one of these information can be used as the current vehicle driving status information. For example, collecting information such as the vehicle's current gear being reverse and its movement direction being forward can be used as the current vehicle driving status information.
[0049] Example 2
[0050] Figure 2 This is a flowchart of another electronic rearview mirror control method provided in Embodiment 2 of the present invention. This embodiment is further optimized and expanded based on the above embodiments.
[0051] like Figure 2 As shown, another electronic rearview mirror control method provided in this embodiment may include:
[0052] S210: Obtain current vehicle driving status information and rearview mirror images collected by the electronic rearview mirror.
[0053] S220. Identify the target object image within the rearview mirror image and determine the acquisition angle within the rearview mirror image according to the target object image.
[0054] In this embodiment, the target identification image can be an image of an object with different positions and angles within the image captured by the rearview mirror. The object can be located at different positions around the vehicle and can only be captured by the rearview mirror at different angles. For example, the target identification image can be an image of the sky, the ground, and the wheels.
[0055] Specifically, after acquiring the rearview mirror image, the target object in the image and its proportion or position in the image captured by the rearview mirror can be analyzed and identified to determine the main viewing angle of the current vehicle. For example, when the target image is the sky and the ground, the proportion of the sky and the ground in the rearview mirror image can be analyzed to determine the acquisition angle of the electronic rearview mirror.
[0056] S230. Determine the current vehicle status based on the current vehicle driving status information, wherein the current vehicle status includes at least one of parking, reversing, or normal driving.
[0057] Specifically, the current vehicle status can be determined by analyzing the obtained current vehicle gear position information, direction of movement, and other driving status information. The current vehicle status can be at least one of parking, reversing, or normal driving. For example, if the obtained current vehicle driving status information is that the vehicle is in reverse gear, the current vehicle status is determined to be reversing. If the obtained current vehicle driving status information is that the vehicle is in drive gear and the direction of movement is forward, the current vehicle status is determined to be normal driving.
[0058] S240. When the correspondence between the current vehicle status and the acquisition viewpoint does not belong to the preset correspondence, determine that the trigger adjustment condition is met, and search for the standard visual area stored in the preset strategy set that is associated with the current vehicle status.
[0059] In this embodiment, the preset correspondence can be a one-to-one correspondence between the acquisition viewpoint and the current vehicle state, pre-set according to the actual situation. For example, when the acquisition viewpoint is the wheel viewpoint, the corresponding current vehicle state is reversing; when the acquisition viewpoint is the sky-to-ground ratio viewpoint, the corresponding current vehicle state is normal driving. The preset strategy set can be a standard visual area corresponding to different vehicle states, pre-set according to the actual situation. This may include the standard visual area of the wheel viewpoint corresponding to the current vehicle state of reversing, the standard visual area of the sky-to-ground ratio viewpoint corresponding to the current vehicle state of normal driving, and the standard visual area of the sky-to-ground ratio viewpoint corresponding to the current vehicle state of parking, etc. Specifically, the acquired rearview mirror image and the current vehicle driving state information can be analyzed to obtain the acquisition viewpoint and the current vehicle state. It can be analyzed whether it is a preset correspondence. If it is not a preset correspondence, it means that the current acquisition viewpoint cannot meet the required viewing range under the current vehicle state. In this case, the conditions for electronic rearview mirror adjustment are met, and the corresponding standard visual area in the strategy set, which is the required viewing range under the current vehicle state, is found according to the current vehicle state.
[0060] S250, a rotary motor that controls the electronic rearview mirror for progressively rotating electronic rearview mirrors.
[0061] In this embodiment, the rotary motor can be a rotating electromagnet operating based on the principle of electromagnetic induction. One rotary motor can be installed near the vehicle body on each of the left and right rearview mirror folding rods. The rotary motors control the rotation of the folding rods, supporting both coarse and fine adjustments to the rearview mirror viewing angle. Specifically, when adjusting the electronic rearview mirror viewing angle, adjustments can be made using the rotary motors installed near the vehicle body. The rotary motors control the rotation of the folding rods by a certain angle, supporting both coarse and fine adjustments. The electronic rearview mirror camera is fixed to the rotary motor shaft to achieve viewing angle adjustment.
[0062] S260: Real-time acquisition of images of the electronic rearview mirror during its rotation.
[0063] Specifically, during the adjustment of the electronic rearview mirror's viewing angle, a camera fixed on the rotating motor shaft continues to capture images of objects around the vehicle, including the sky, the ground, and the wheels. As the rotating motor controls the folding rod to rotate, the camera's shooting angle also changes, capturing images of the vehicle's surroundings during the process of adjusting the rearview mirror's visual area to the standard visual area.
[0064] S270. The adjustment is completed when the visual area of the image during the rotation process is consistent with the preset standard visual area of the current vehicle driving status information.
[0065] Specifically, the real-time visual area of the electronic rearview mirror during the rotation process can be obtained by analyzing objects such as the sky, the ground, and the wheels in the image and their proportion or position in the image. When the visual area is consistent with the standard visual area set according to the current vehicle driving status information, that is, when the current visual area meets the viewing angle range required under the current vehicle status, the adjustment of the electronic rearview mirror is stopped.
[0066] The technical solution provided by this invention acquires current vehicle driving status information and rearview mirror images captured by an electronic rearview mirror. It analyzes the electronic rearview mirror's acquisition angle and the current vehicle status to determine if they correspond to a preset relationship. If not, it searches for a standard visual area associated with the current vehicle status within a preset strategy set and gradually rotates the electronic rearview mirror using a rotary motor to adjust its acquisition angle. During this process, it acquires images of the rotation process in real time to analyze the real-time acquisition angle of the electronic rearview mirror and determine if it matches the standard visual area of the current vehicle status. When the visual area of the rotation process image matches the preset standard visual area of the current vehicle driving status information, the adjustment is completed. This achieves rapid determination of the standard visual area of the current vehicle driving status and real-time automatic adjustment of the electronic rearview mirror. It realizes real-time automatic adjustment of the electronic rearview mirror based on a rotary motor, which is relatively easy to implement, cost-effective, and widely applicable, thus improving vehicle driving safety.
[0067] Based on the above embodiments, the preset correspondence includes at least one of the following:
[0068] When the data collection perspective is the air-to-space ratio perspective, the current vehicle status is normal driving;
[0069] When the camera is viewed from the wheel perspective, the current vehicle is in reverse.
[0070] In this embodiment, the sky-to-ground ratio viewing angle can be the image captured by the electronic rearview mirror. When the target recognition image consists of the sky and the ground, the electronic rearview mirror acquisition viewing angle is determined by analyzing the proportions of the sky and the ground in the rearview mirror image. For example, see [link to example]. Figure 6 When the target recognition image consists of sky 01 and earth 02, and the ratio of sky 01 to earth 02 in the image is 6:4, then the current electronic rearview mirror's acquisition perspective is the sky-to-sky ratio perspective. The wheel perspective can be the image acquired by the electronic rearview mirror. When the target recognition image is a wheel, the acquisition perspective is determined by whether the wheel appears completely in the acquisition position in the rearview mirror image. For an example, see [link to example]. Figure 7 When the target image is wheel 102, and wheel 102 appears completely at the acquisition position 101 in the image, then the current acquisition angle of the electronic rearview mirror is the wheel angle.
[0071] Specifically, there is a pre-set one-to-one correspondence between the viewing angle collected by the electronic rearview mirror and the current driving status of the vehicle. The current vehicle status can be obtained by analyzing the current viewing angle of the rearview mirror. This one-to-one correspondence may include at least one of the following: when the viewing angle is the sky-to-ground ratio view, the current vehicle status is normal driving; when the viewing angle is the wheel view, the current vehicle status is reversing. For example, when the viewing angle is the sky-to-ground ratio view, the current vehicle status is determined to be normal driving according to the preset correspondence.
[0072] Based on the above embodiments, the rearview mirror image or the rotation process image is processed by a preset image feature extraction model for image acceleration, wherein the preset image feature extraction model includes at least a convolutional neural network model.
[0073] In this embodiment, image acceleration processing can be an image processing method that extracts features from an image based on a deep learning model; the convolutional neural network model can be a feedforward neural network, whose artificial neurons can respond to a portion of the surrounding units within the coverage area. It is the most widely used network structure in the field of image processing and can accelerate the recognition of target images in rearview mirror images and rotation process images.
[0074] Specifically, in order to more quickly identify and extract the image features of the target object in the image or rotation process image captured by the electronic rearview mirror, a preset image feature extraction model can be used to speed up the image feature extraction. The preset image feature extraction model can include at least a convolutional neural network model, or other deep learning models, such as neural network models, restricted Boltzmann machines, etc.
[0075] Based on the above embodiments, the acquisition angle is determined according to the target object image within the rearview mirror image, including:
[0076] When the target recognition image consists of the sky and the ground, the acquisition angle is determined according to the proportion of the sky and the ground occupying the rearview mirror image, respectively.
[0077] When the target image is a wheel, the acquisition angle is determined according to the position of the wheel in the rearview mirror image.
[0078] Specifically, the acquisition angle can be determined based on the proportion of the target object within the rearview mirror image. This can include determining the acquisition angle according to the proportion of the sky and the ground occupying the rearview mirror image, respectively, when the target image consists of the sky and the ground. For an example, see [link to example]. Figure 6When the target recognition image consists of sky 01 and earth 02, and the ratio of sky 01 to earth 02 in the image is 6:4, then the current electronic rearview mirror's acquisition perspective is the sky-to-sky ratio perspective. The wheel perspective can be the image acquired by the electronic rearview mirror. When the target recognition image is a wheel, the acquisition perspective is determined by whether the wheel appears completely in the acquisition position in the rearview mirror image. For an example, see [link to example]. Figure 7 When the target image is wheel 102, and wheel 102 appears completely at the acquisition position 101 in the image, then the current acquisition angle of the electronic rearview mirror is the wheel angle.
[0079] Example 3
[0080] Figure 3 This is a flowchart of another electronic rearview mirror control method provided in Embodiment 2 of the present invention. This embodiment is further optimized and expanded based on the above embodiments.
[0081] like Figure 3 As shown, another electronic rearview mirror control method provided in this embodiment may include:
[0082] S310, rearview mirror image acquisition.
[0083] Specifically, it can collect information from the left / right rearview mirrors, and can collect data at a set number of frames per second, for example, at 60 frames per second.
[0084] S320, Gear information collection.
[0085] Specifically, it can collect and analyze the vehicle's current gear status information. For example, it can collect whether the vehicle is currently in reverse gear and analyze whether the vehicle is reversing.
[0086] S330, image acceleration processing, to obtain air-to-sky ratio viewpoint features and wheel viewpoint features.
[0087] Specifically, deep learning models can be used to accelerate the processing of image information from the left / right rearview mirrors of a vehicle, and obtain the sky-to-sky ratio and wheel perspective features. For example, a convolutional neural network model can be used to accelerate the processing of image information from the left / right rearview mirrors of a vehicle, analyze the proportion or position of the sky, ground, wheels, etc. in the rearview mirror image, and obtain the sky-to-sky ratio and wheel perspective features.
[0088] S340: Determine if the vehicle is currently in reverse gear and adjust the rearview mirror angle adjustment mode.
[0089] Specifically, the gear position information can be used to determine if the vehicle is in a non-reverse gear, and the angle adjustment mode can be switched to the air-to-sky ratio view mode; if the gear position information is used to determine if the vehicle is in reverse gear, the angle adjustment mode can be switched to the wheel view mode.
[0090] S350: The rearview mirror angle is adjusted using PID control according to the target's viewing angle relative to the airspace.
[0091] In this embodiment, the target for the air-to-space ratio viewing angle can be a pre-set or user-inputted range of the electronic rearview mirror's field of view when the vehicle is in a non-reverse gear; PID regulation is a basic regulation method of control system in classical control theory. It is a linear regulation law with proportional, integral and derivative actions, which can stably adjust the angle of the rotating motor.
[0092] Specifically, the sky-to-sky ratio viewing angle features obtained from image acceleration processing can be adjusted using PID control according to the default settings or the sky-to-sky ratio viewing angle target input by the customer, so that the sky-to-sky ratio viewing angle features obtained from image acceleration processing are consistent with the target.
[0093] S360: Adjusts the rearview mirror angle using PID control based on the target's perspective from the wheel.
[0094] In this embodiment, the target wheel view can be a pre-set or user-inputted range of the electronic rearview mirror's field of view when the vehicle is in reverse gear.
[0095] Specifically, the wheel view features obtained from image acceleration processing can be used to adjust the angle of the rotary motor using PID control, based on the default settings or the wheel view target input by the customer, so that the wheel view features obtained from image acceleration processing are consistent with the target.
[0096] The technical solution provided by this invention obtains the current vehicle gear information and the rearview mirror image captured by the electronic rearview mirror, performs image acceleration processing on the rearview mirror image to obtain the air-to-sky ratio angle feature and wheel angle feature, determines whether the vehicle is in reverse gear based on the gear information, adjusts the rearview mirror angle adjustment mode, and performs PID adjustment of the rearview mirror angle according to the air-to-sky ratio angle target / vehicle angle target. This achieves rapid matching between the current vehicle gear and the rearview mirror angle adjustment mode and real-time automatic adjustment of the electronic rearview mirror, thereby improving the safety of vehicle driving.
