With continued reference to fig. 2, a flow 200 of one embodiment of a method for transmitting information in accordance with the present disclosure is shown. The method for transmitting information comprises the following steps:
In this embodiment, the execution subject of the method for transmitting information (e.g., the terminal devices 101, 102, 103 shown in fig. 1) can receive the destination floor information transmitted by the user through the operation panel in the elevator car by a wired connection manner or a wireless connection manner. Thereafter, the execution body can acquire a video acquired by the image acquisition device (e.g., a camera) installed in the elevator car.
In practice, a camera can be installed in the elevator car of the elevator, and the camera can collect videos in the elevator car. For example, a camera may be mounted on top of an elevator car so that the camera may capture video of elevator occupants within the elevator car and send the captured video to the executive.
Generally, after a user has carried out an elevator car, destination floor information, which is floor information of a destination floor to which the user intends to go, is transmitted by using an operation panel in the elevator car. Generally, an operation panel in the elevator car is disposed at both sides of an entrance of the elevator car, and the operation panel may include a plurality of buttons, and the buttons may be marked with numbers corresponding to floors, door opening marks, door closing marks, or the like.
And 202, identifying the acquired video, and determining a target human body from the acquired video according to an identification result.
In this embodiment, the execution subject may recognize a video frame of the acquired video and determine the target human body from the acquired video according to the recognition result. As an example, the executing subject may first perform human detection on a video frame of the acquired video, resulting in at least one human frame. Then, the execution subject may recognize a target human body frame from the at least one human body frame, and use a human body corresponding to the target human body frame as a target human body. For example, after receiving the target floor information sent by the user through the operation panel in the elevator car, the execution main body may identify a human body frame closest to the operation panel in the acquired first video frame in the elevator car as a target human body frame, and use a human body corresponding to the target human body frame as the target human body. In general, the user closest to the operation panel at this time is the target user who transmits the target floor information, that is, the human body of the target user is the target human body.
In some optional implementations of this embodiment, the step 202 may specifically be performed as follows: and performing human behavior recognition based on the acquired video, and taking a human body operating the operation panel as a target human body.
In this implementation, the execution main body may perform human behavior recognition on a human body in the acquired video by using various behavior recognition methods, and use the human body operating the operation panel as a target human body. As an example, a conventional behavior recognition method, such as a template-based method, a probability statistics-based method, a semantic-based method, and the like, may be employed, and a human behavior recognition algorithm based on deep learning may also be employed.
And 203, responding to the situation that the target floor is reached after the first preset time length of the elevator car is predicted, and determining whether the time length that the target human body watches the floor display screen in the elevator car exceeds a second preset time length or not based on the acquired video.
In this embodiment, the executive agent may predict that the elevator car reaches the target floor after a first preset length of time. For example, the executive body can predict the time of the elevator car reaching each floor according to the information of the position, the running speed, the number of floors to be stopped midway and the like of the elevator car. If the executive agent predicts that the elevator car will reach the target floor after the first preset duration, the executive agent may further determine whether the duration that the target human is gazing at the floor display screen within the elevator car exceeds a second preset duration based on the acquired video. As an example, the executive may utilize existing eye tracking technology to determine whether the eyes of the target person are looking at the floor display within the elevator car. Here, the first preset time period and the second preset time period may be set according to actual needs, and are not limited herein.
In practice, for the convenience of elevator passengers, a floor display screen is often arranged in the elevator car and used for displaying the floor reached by the elevator car at the current time.
In some optional implementation manners of this embodiment, in step 203, based on the obtained video, it is determined whether a duration that the target human body gazes at the floor display screen in the elevator car exceeds a second preset duration, which may include the following:
firstly, for a video frame of an acquired video, identifying a face angle of a target human body in the video frame, and determining whether the face angle of the target human body in the video frame is within a preset angle range; and in response to determining that the face angle of the target human body in the video frame is within a preset angle range, marking the video frame as a target video frame.
In this implementation, when the execution subject predicts that the elevator car will reach the target floor after the first preset time period, for each video frame of the currently acquired video, the face angle of the target human body in the video frame may be identified in various manners, for example, a template-based method, a face set feature-based method, a deep learning-based method, and the like, so as to determine whether the face angle of the target human body in the video frame is within the preset angle range. And if the face angle of the target human body in the video frame is determined to be in a preset angle range, marking the video frame as a target video frame. Here, the preset angle range may be related to the installation position of the floor display screen in the elevator car. As an example, the preset angle range may be obtained by a technician based on statistics of the face angles of a plurality of users looking at the floor display screen in the elevator car.
Then, in response to determining that the number of frames of the target video frames in the acquired video continuously appears exceeds a preset frame number threshold, determining that the time length of the target human body watching the floor display screen in the elevator car exceeds a second preset time length.
In the implementation mode, the execution main body can count whether the number of continuous frames of the target video frames in the obtained video exceeds a preset frame number threshold value, and if the number of continuous frames of the target video frames in the obtained video exceeds the preset frame number threshold value, the duration that the target human body watches the floor display screen in the elevator car is determined to exceed a second preset duration. Here, the frame number threshold may be determined according to a second preset duration. For example, the frame number threshold may be a product of the second preset duration and the video frame rate of the acquired video.
And 204, in response to the fact that the time length that the target human body watches the floor display screen does not exceed the second preset time length and the fact that the elevator door is opened after the elevator car reaches the target floor, determining whether the target human body leaves the elevator car or not according to the human body tracking result aiming at the target human body.
In this embodiment, if it is determined that the time period for which the target human body gazes at the floor display screen does not exceed the second preset time period, and at the same time, it is determined that the elevator car has reached the target floor and the elevator door has been opened, the execution main body may determine whether the target human body leaves the elevator car according to the human body tracking result for the target human body. As an example, the execution subject, after determining the target human body, may track the target human body based on the acquired video to determine whether the target human body leaves the elevator car. For example, when tracking a target human body, if the target human body disappears from a video, it can be determined that the target human body has left the elevator car.
In some optional implementations of the present embodiment, the human tracking result may include the presence and absence of the target human. And step 204, determining whether the target human body leaves the elevator car according to the human body tracking result aiming at the target human body, wherein the method specifically comprises the following steps:
1) and in response to determining that the human tracking result is that the target human exists, determining that the target human does not leave the elevator car.
In this implementation, the execution subject may determine that the target human body does not leave the elevator car if it is determined that the human body tracking result is that the target human body exists.
2) And in response to determining that the human tracking result is that the target human disappears, determining that the target human has left the elevator car.
In this implementation, the execution subject may determine that the target human body has left the elevator car if it is determined that the human body tracking result is that the target human body disappears.
And step 205, responding to the fact that the target human body does not leave the elevator car, and sending prompt information.
In this embodiment, if it is determined that the target human body does not leave the elevator car, the execution main body may send a prompt message to the playback device in the elevator car for the playback device to present. If it is determined that the target human body has left the elevator car, the execution subject may determine not to send the prompt message to the playback device within the elevator car.
Here, the prompt information may be information in a voice form. Taking the playing device as an example of a loudspeaker, the execution main body can send voice prompt information to the loudspeaker, and the voice prompt information is played by the loudspeaker to prompt that a target human body elevator car in the elevator car reaches a target floor. As an example, the playback device may play the voice guidance information multiple times in succession.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the method for transmitting information according to the present embodiment. In the application scenario of fig. 3, after the user enters the elevator car, the destination floor information "12" is transmitted to the terminal device 301 through the operation panel in the elevator car. In response to receiving the destination floor information "12" transmitted by the user, the terminal device 301 may acquire the video within the elevator car. After that, the terminal device 301 may recognize the acquired video and determine the target human body a from the acquired video according to the recognition result. In response to predicting the elevator car to reach the target floor 12 after the first preset duration "2 minutes", the terminal device 301 may determine whether the duration that the target human body a gazes at the floor display screen in the elevator car exceeds the second preset duration "1 second" based on the acquired video. If it is determined that the time length that the target human body A gazes at the floor display screen does not exceed the second preset time length of 1 second, and it is determined that the elevator door is opened after the elevator car reaches the target floor of 12 floors, the terminal device 301 may determine whether the target human body A leaves the elevator car according to the human body tracking result for the target human body A. If it is determined that the target human body a does not leave the elevator car, the terminal device 301 may send a voice prompt message "you are good, floor 12 has been reached" to a speaker in the elevator car.
The method provided by the embodiment of the disclosure realizes that the prompt message is sent when the target human body watching floor display screen does not exceed the second preset time and does not leave at the target floor, so as to prompt that the target human body elevator car reaches the target floor.
With further reference to fig. 4, a flow 400 of yet another embodiment of a method for transmitting information is shown. The process 400 of the method for transmitting information includes the steps of:
and step 401, in response to receiving the target floor information sent by the user through the operation panel in the elevator car, acquiring a video in the elevator car.
In this embodiment, step 401 is similar to step 201 of the embodiment shown in fig. 2, and is not described here again.
And 402, identifying the acquired video, and determining a target human body from the acquired video according to an identification result.
In this embodiment, step 402 is similar to step 202 of the embodiment shown in fig. 2, and is not described herein again.
And 403, in response to the fact that the target floor is reached after the first preset time length of the elevator car is predicted, determining whether the time length that the target human body watches the floor display screen in the elevator car exceeds a second preset time length or not based on the acquired video.
In this embodiment, step 403 is similar to step 203 of the embodiment shown in fig. 2, and is not described herein again.
And step 404, in response to the fact that the time length that the target human body watches the floor display screen does not exceed the second preset time length and the fact that the elevator door is opened after the elevator car reaches the target floor, determining whether the target human body leaves the elevator car according to the human body tracking result aiming at the target human body.
In this embodiment, step 404 is similar to step 204 of the embodiment shown in fig. 2, and is not described here again.
In this embodiment, step 405 is similar to step 205 of the embodiment shown in fig. 2, and is not described herein again.
And step 406, in response to the fact that the time length that the target human body gazes at the floor display screen exceeds a second preset time length and the fact that the elevator door is opened after the elevator car reaches the target floor, determining not to send prompt information.
In this embodiment, if it is determined that the time period during which the target human body gazes at the floor display screen in the elevator car exceeds the second preset time period while it is determined that the elevator car has reached the target floor and the elevator door has been opened, the execution main body may determine not to send the prompt message. That is, in the case where it is determined that the target human body has viewed the floor display screen, no prompt message is sent regardless of whether the target human body has left the elevator at the target floor.
As can be seen from fig. 4, compared with the embodiment corresponding to fig. 2, the flow 400 of the method for sending information in the present embodiment highlights a step of not sending the prompt message in case that the target human body has looked at the floor display for more than the second preset time period. Therefore, the scheme described by the embodiment can send the prompt message more specifically, and unnecessary disturbance to passengers in the elevator car is reduced.
