Technical Field

[0001] The present disclosure relates to the field of vehicle control technology, and in particular to a vehicle boarding reminder processing method, device and medium. Background Art

[0002] During daily travel, drivers often judge whether passengers are on board based on the sound of the door opening and closing. After hearing the door closing sound, the driver assumes that the passengers are on board and drives away.

[0003] However, in many actual application scenarios, even if the sound of the door opening and closing occurs, it is possible that the passengers have not yet gotten on the vehicle. For example, the rear-seat passenger opens the door and finds that there are items on the seat on his side and cannot sit down, so he closes the door and intends to get in from the other side of the vehicle. In this driving situation, the driver hears the door opening and closing, and thus assumes that the rear-seat passengers are seated, resulting in the vehicle being driven away directly without the passengers being seated. Summary of the invention

[0004] In order to solve the above technical problems or at least partially solve the above technical problems, the present disclosure provides a method, device and medium for processing a boarding reminder.

[0005] An embodiment of the present disclosure provides a method for processing a boarding reminder, the method comprising: after the vehicle is started, identifying whether there is an opening and closing process of the rear door of the vehicle; if so, obtaining motion data of a person outside the vehicle within a preset range from the vehicle, and when the motion data of the person outside the vehicle is determined to be abnormal, sending a passenger left-behind reminder to the vehicle.

[0020] In order to solve the above problems, an embodiment of the present disclosure provides a method for processing a boarding reminder, which is introduced below in conjunction with a specific embodiment.

[0021] Figure 1 The present invention provides a flow chart of a method for processing a boarding reminder, which can be executed by a boarding reminder processing device, wherein the device can be implemented by software and / or hardware, and can generally be integrated into an electronic device. Figure 1 As shown, the method includes:

[0022] Step 101, after the vehicle is started, identifying whether the rear door of the vehicle is in the opening and closing process.

[0023] In one embodiment of the present disclosure, after the vehicle is started, it is identified whether the rear door of the vehicle is in the opening and closing process, that is, it is detected whether the user intends to get in the vehicle. That is, after the vehicle is started, the identification of the opening and closing process of the rear door is started.

[0024] It should be noted that in different application scenarios, the method of identifying whether the rear door of the vehicle is in the opening and closing process is different, and the specific implementation method may be a combination of one or more of the following examples, as follows:

[0025] In some possible embodiments, image information of the rear door is obtained, for example, by communicating with a preset monitoring system to obtain image information of the rear door taken by a monitoring camera, or by collecting image information of the rear door through a camera installed in the vehicle to extract image features of the image information. In this embodiment, it is identified whether the rear door is in the opening and closing process based on the image features. The camera installed in the vehicle can be installed at a position such as the B-pillar of the vehicle or the rearview mirror inside the vehicle.

[0026] For example, a plurality of continuous image features corresponding to a plurality of continuous frames of images are input into a pre-trained artificial intelligence model, and the artificial intelligence model determines whether the door is opened or closed based on the image features, because the image features of the door opening and closing are different. In this embodiment, since the opening and closing process includes two actions, after first recognizing that the door is opened based on the image features of the image information of the rear door, the image information of the door is continuously acquired. If the rear door is recognized to be closed based on the image features of the acquired image information of the rear door within a preset time period, it is determined that the rear door is in the opening and closing process.

[0027] In some possible embodiments, the sound information of the rear door is collected by a preset microphone, wherein the preset microphone can be pre-set in the vehicle, such as at the B-pillar of the vehicle, the rearview mirror inside the vehicle, etc., to extract the sound features of the sound information, and identify whether the rear door is in the opening and closing process according to the sound features. In this embodiment, the sound features can be input into a pre-trained artificial intelligence model, and the artificial intelligence model identifies the propagation direction and intensity difference of the sound through the sound features, and determines whether the door is opened and closed based on the propagation direction and intensity difference of the door opening and closing obtained in advance. Among them, since the opening and closing process includes opening and closing, which are two actions, therefore, after first identifying that the door is opened according to the sound features of the rear door, the sound information of the door is continuously obtained. If the rear door is identified to be closed according to the sound features of the sound information of the rear door obtained within the preset time, it is determined that the rear door is in the opening and closing process.

[0028] In some possible embodiments, the angle between the rear door and the vehicle body is identified according to a preset angle sensor, wherein the preset angle sensor may be arranged at the door hinge of the rear door. In this embodiment, the angle between the rear door and the vehicle body is identified according to the preset angle sensor, and whether the rear door is in the opening and closing process is identified according to the angle. When the angle is less than the preset angle threshold, it is determined that the rear door is closed, and when the angle is greater than the preset angle threshold, it is determined that the rear door is open.

[0029] Step 102, if yes, then obtain the motion data of the person outside the vehicle within a preset range from the vehicle, and when the motion data of the person outside the vehicle is determined to be abnormal, send a passenger left behind reminder to the vehicle.

[0030] After the rear door is opened and closed, that is, after the rear door is opened first and then closed, the motion data of the person outside the vehicle within the preset range of the vehicle is obtained, wherein the motion data includes at least one of body motion data, sound motion data, lip shape data, etc. The preset range can be set according to the scene requirements, and the purpose of setting the preset range is to avoid the problem of large computing power consumption when identifying the motion data of all people outside the vehicle around the vehicle.

[0031] After acquiring the motion data, it is determined whether the motion data of the person outside the vehicle is abnormal based on the motion data. That is, in this embodiment, it is determined based on the motion data whether the person outside the vehicle is a left-behind passenger who wanted to get on the vehicle but failed to get on the vehicle. If the motion data of the person outside the vehicle is abnormal, it is considered that the corresponding person outside the vehicle is a left-behind passenger.

[0032] Furthermore, when the motion data of a person outside the vehicle is determined to be abnormal, a passenger-left-behind reminder is sent to the vehicle.

[0033] In one embodiment of the present disclosure, when the motion data of a person outside the vehicle is determined to be abnormal, a passenger left behind reminder is sent to the vehicle to remind the driver that there are passengers who have not yet boarded the vehicle, thereby preventing the driver from leaving the vehicle.

[0034] Among them, in some possible embodiments, when the motion data of the person outside the vehicle is determined to be abnormal, the vehicle can also be subjected to emergency braking to ensure the safety of the person outside the vehicle. Among them, before the emergency braking is performed, a braking reminder message can also be sent to the driver. If the driver does not receive a rejection operation of the braking reminder message within a preset time, the vehicle is subjected to emergency braking. In this embodiment, in order to further ensure that the emergency braking will not cause safety problems, when the motion data of the person outside the vehicle is determined to be abnormal, it is also necessary to determine that the current distance between the person outside the vehicle and the vehicle is less than the preset distance threshold before the vehicle is subjected to emergency braking. In other possible embodiments, when the motion data of the person outside the vehicle is determined to be abnormal, but the current distance between the person outside the vehicle and the vehicle is greater than the preset distance threshold, in order to avoid potential safety hazards, the vehicle is not subjected to emergency braking, and only a message is sent to the driver to remind the person outside the vehicle to get on the vehicle.

[0035] It should be noted that in different application scenarios, the methods for processing the boarding reminder in the vehicle are different, as shown below:

[0036] In one embodiment of the present disclosure, a message corresponding to the passenger left-behind reminder may be generated, and then the passenger left-behind reminder may be voice broadcasted in the vehicle.

[0037] Based on the above embodiment, after the vehicle is started, if it is detected that the door is opened, emergency braking is performed on the vehicle, for example, pulling up the vehicle handbrake.

[0038] The following is a description of the determination of whether the motion data of the person outside the vehicle is abnormal in the above step 102 in combination with a specific embodiment. The following different embodiments can be implemented separately or in combination with each other, as described below:

[0039] In one embodiment of the present disclosure, video stream information of people outside the vehicle within a preset range from the vehicle is obtained, wherein the video stream information includes multiple continuous video frames. For example, the video stream information of people outside the vehicle can be obtained through an external camera, and then, motion data is obtained based on the multiple continuous video frames.

[0040] For example, the joint point position set of the person outside the vehicle in each video frame can be identified, where Figure 2 The joint point position set of the person outside the vehicle at least includes knee joints, ankle joints, elbow joints, shoulder key nodes, hand joints, etc.

[0041] In this embodiment, a plurality of continuous joint point position sets corresponding to a plurality of continuous video frames are obtained as action data, so that the action type of the person outside the vehicle can be further determined based on the plurality of continuous joint point position sets. For example, the plurality of continuous joint point position sets can be input into a pre-trained deep learning model, and the action type of the person outside the vehicle is identified based on the deep learning model. In this embodiment, it is determined whether the action type belongs to a preset action type. When the action type belongs to the preset action type, the action data of the person outside the vehicle is determined to be abnormal. The preset action types may include: reaching out to open the door, chasing the vehicle, etc.

[0042] In this embodiment, if the preset action type is identified as a standing still action, multiple continuous video frames are continuously acquired according to the preset duration, and based on the continuously acquired multiple video frames, it is identified whether the person outside the vehicle continues to stay still. If the person continues to stay still, the action data of the person outside the vehicle is determined to be abnormal.

[0043] In one embodiment of the present disclosure, when the motion data includes sound data, the sound data can be collected through a preset microphone, and it is identified based on the sound data whether it contains preset keywords such as "I haven't gotten in the car yet" or "Don't drive". If it contains the preset keywords, the motion data of the person outside the car is determined to be abnormal.

[0044] In this embodiment, multiple consecutive video frames may be collected to obtain lip shape data, and the lip shape data and the sound data may be combined to determine whether the preset keywords are included.

[0045] In summary, the boarding reminder processing method of the disclosed embodiment identifies whether the rear door of the vehicle is in the process of opening and closing after the vehicle is started, and then obtains the motion data of the person outside the vehicle within a preset range of the vehicle after the opening and closing process occurs, determines whether the person outside the vehicle is abnormal based on the motion data, and sends a passenger left behind reminder to the vehicle when the motion data of the person outside the vehicle is determined to be abnormal. In this technical solution, the vehicle is prevented from leaving when the outside passengers have not boarded the vehicle, thus avoiding the problem of passengers being left behind.
