[0032] In order to make the purpose, technical solutions and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The described embodiments should not be regarded as limiting this application. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0033] In the following description, reference is made to “some embodiments”, which describes a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0034] In the following description, the terms "first\second\third" involved are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein are for the purpose of describing the embodiments of this application only and are not intended to limit this application.

[0036] To address the problems in the related art, embodiments of the present application provide a doorbell hanging up method. The method provided in embodiments of the present application can be implemented via a computer program. When executed, the computer program completes each step of the doorbell hanging up method provided in embodiments of the present application. In some embodiments, the computer program can be executed by a processor in a doorbell hanging up device. Figure 1 This is a schematic diagram of an implementation flow of the doorbell hang-up method provided in an embodiment of the present application. The method can be applied to a server, which can establish a communication connection between the doorbell and the target terminal. The server can also make a judgment based on the received information and control whether to initiate or end the door opening call based on the judgment result. Figure 1 As shown, the method includes:

[0037] Step S101 : In response to a pressing operation on a doorbell, video data currently captured by an image capture device is acquired, and a plurality of video frame images are acquired based on the video data.

[0038] Here, the doorbell is provided with a pressable module, and the pressing operation on the doorbell can be a pressing operation on the pressable module of the doorbell; the image acquisition device can be a camera, a video camera, etc., and the image acquisition device can be integrated with the doorbell or a monitoring device independent of the doorbell. The video data can be video data of the corridor outside the door, aisle, etc.

[0039] In an embodiment of the present application, after obtaining the currently collected video data, the server may capture video frame images from the video data according to a preset period. For example, if the preset period is 1 second, one image is captured every 1 second, thereby obtaining multiple video frame images. Alternatively, video frame images may be captured from the video image non-periodically. This embodiment of the present application does not limit the implementation method for obtaining multiple video frame images based on video data.

[0040] Step S102: When it is determined based on a plurality of video frame images within a preset time period that a call condition is met, a door opening call is initiated to a target terminal.

[0041] Here, the preset duration can be 1 second, 2 seconds, etc., and the preset duration can be a default value or a custom setting value. The video frame image within the preset duration includes at least one, and the number of video frame images within the preset duration is related to the preset duration and the video capture rule. For example, when the preset duration is 2 seconds and video data is captured at a 1-second periodicity, 2 video frame images can be captured within 2 seconds. In this case, there are 2 video frame images within the preset duration.

[0042] In this embodiment of the present application, the starting point of the preset duration is consistent with the starting point of the video data. That is, the multiple video frames within the preset duration are the video frames with earlier time points among the multiple video frames acquired in step S101. Here, the target terminal can be an indoor LCD display, a mobile phone, a smart wearable device, etc., which can identify the multiple video frames within the preset duration. When at least one video frame is identified as containing a human image, the call condition is considered to be met, and a door opening call is initiated to the target terminal.

[0043] In some embodiments, if it is recognized that no human image is contained in any video frame image, it is considered that the call condition is not met, and a door opening call is not initiated to the target terminal. When the doorbell is accidentally touched, a door opening call will not be initiated to the homeowner, thereby improving the intelligence of the call.

[0044] Step S103: performing image processing on the multiple video frame images to determine the state of the target object.

[0045] Here, the target object includes at least one of a door body and a human body, and the image processing may include: image feature extraction, image recognition, image detection, etc.

[0046] Among them, when the target object is a door body, each image feature of each video frame image can be extracted, and then the various difference information between each image feature and the reference feature can be determined, wherein the reference feature is a feature screen extracted from the reference image representing the closed door body; if there is difference information greater than the difference threshold, it indicates that the door body is not in a closed state, and the state of the door body is determined to be an open state; and when each difference information is less than or equal to the difference threshold, the state of the door body is determined to be a closed state.

[0047] When the target object is a human body, image recognition can be performed on each video frame image. When it is identified that none of the video frame images contain a human body image, it is determined that the human body is in a leaving state. When it is identified that at least one video frame image contains a human body image, the video frame image containing the human body image is determined as the target video frame image. The distance information of the human body from the image acquisition device in the target video frame image is determined. Then, the direction of movement of the human body is further judged in combination with the time information of the target video frame image and the determined distance information. When it is determined that the human body is moving away from the image acquisition device, it is considered that the human body is in a leaving state. When it is determined that the distance between the human body and the image acquisition device remains almost unchanged or is moving toward the image acquisition device, it is considered that the human body is in a present state.

[0048] Step S104: When it is determined based on the state of the target object that a call termination condition is met, the door opening call is terminated.

[0049] In an embodiment of the present application, when the target object is a door, the call termination condition can be considered to be satisfied when the door is in an open state; when the target object is a human body, the call termination condition can also be considered to be satisfied when the human body is in a away state. Then, when the call termination condition is satisfied, either the door is already in an open state, indicating that the purpose of the door opening call has been achieved and there is no need to continue initiating the door opening call; or the human body is in a away state, indicating that the human body no longer needs to call the door and there is no need to continue initiating the door opening call. Based on this, an end instruction can be sent to the target terminal to cause the target terminal to stop the door opening call; when the target objects are a door and a human body, when the door is in an open state or the human body is in a away state, the call termination condition is considered to be satisfied, thereby terminating the door opening call to the target terminal.

[0050] In some embodiments, when the target object is a door, if the door is in a closed state, it can be considered that the call end condition is not met; when the target object is a human body, if the human body is in an existing state, it can also be considered that the call end condition is not met. Then, if the call end condition is not met, either the door is still in a closed state, indicating that the purpose of the door opening call has not been achieved and the door opening call still needs to be initiated; or the human body is still in an existing state, indicating that the human body still has a door opening call demand and the door opening call still needs to be initiated. In this case, it can also be determined based on the state of the target object that the call end condition is not met, and the door opening call is continued to be initiated to the target terminal even if the call end condition is not met; when the target objects are a door and a human body, if the door is in a closed state and the human body is in an existing state, it is considered that the call end condition is not met, and the door opening call is continued to be initiated to the target terminal.

[0051] An embodiment of the present application provides a doorbell hanging up method, which responds to a pressing operation on the doorbell, obtains video data currently collected by the image acquisition device, and intercepts and processes the video data to obtain multiple video frame images; then, intercepts multiple video frame images within a preset time length, and when the multiple video frame images within the preset time length meet the call conditions, initiates a door opening call to the target terminal. In this way, it is possible to automatically determine whether a call needs to be initiated to the target terminal based on the video frame images, thereby improving intelligence and automation; then, image processing is performed on the multiple video frame images, and the state of the target object is determined based on the image processing results, wherein the target object includes at least one of a door body and a human body; finally, when the target object meets the call end condition, the door opening call will be ended. In this way, during the call process, the state of the target object can be timely judged, and the door opening call can be automatically ended when the target state meets the call end condition, thereby avoiding disturbing the homeowner and realizing intelligent calling.

[0052] Based on the above embodiment, the embodiment of the present application further provides an interactive method for doorbell hang-up, which can be applied to the doorbell, server and target terminal, and can automatically end the call during the process of initiating the door opening call, such as Figure 2 As shown, the method includes:

[0053] In step S201, the doorbell sends the received pressing operation to the server.

[0054] Here, the doorbell and the server can establish a communication connection via wired or wireless communication, based on which the doorbell can send the received pressing operation to the server.

[0055] In step S202 , the server obtains the video data currently captured by the image capture device in response to the pressing operation on the doorbell, and obtains a plurality of video frame images based on the video data.

[0056] Here, the server can establish information interaction with the image acquisition device based on the received pressing operation and obtain the video data currently acquired by the image acquisition module, that is, the video data is the video data when the doorbell receives the pressing operation.

[0057] In step S203 , the server performs image recognition on each video frame image within a preset time length to obtain each second recognition result.

[0058] Here, each second recognition result can be used to indicate whether each video frame image within a preset time length contains a human body image.

[0059] In an embodiment of the present application, images can be recognized through methods such as neural networks, wavelet moments, fractal features, etc. to identify whether each video frame image contains a human body image.

[0060] In step S204 , the server determines whether each second recognition result indicates that at least one video frame image in each video frame image within a preset time length contains a human body image.

[0061] Here, if at least one video frame image contains a human image, it indicates that there is a visitor outside the door, that is, the visitor is waiting outside the door to open the door, and the process goes to step S206; if each video frame image does not contain a human image, it indicates that there is no visitor outside the door, and the doorbell pressing operation is a wrong operation, and the process goes to step S205.

[0062] Step S205: The server does not initiate a door opening call to the target terminal.

[0063] At this time, there is no visitor outside the door, and pressing the doorbell is an erroneous operation. In order not to disturb the homeowner, the server does not initiate a door opening call to the target terminal.

[0064] Step S206: The server determines that the call condition is met and initiates a door opening call to the target terminal.

[0065] At this time, there is a visitor outside the door, that is, the visitor is waiting outside the door to open the door, and the event needs to be notified to the homeowner through a door opening call. Then, the server initiates a door opening call to the target terminal.

[0066] Step S207: The target terminal initiates a door opening call.

[0067] Here, the target terminal can initiate a door opening call through ringing, vibration, etc., so that the homeowner knows the time when the visitor is outside the door and makes preliminary preparations for opening the door and making a call.

[0068] Step S208: The server obtains reference features.

[0069] Here, the reference features are features extracted from a reference image representing the door closed state. Before step S202, the server obtains a reference image of the door closed state in advance through an image acquisition device and performs feature extraction on the reference image to obtain the reference features.

[0070] In step S209 , the server extracts image features of each video frame image and determines each difference information between each image feature and a reference feature.

[0071] Here, feature extraction methods such as oriented gradient histogram and scale-invariant feature transform can be used to extract features of each video frame image, so as to obtain the image features of each video frame image; then, the absolute value of the difference between each image feature and the reference feature, the square of the difference or the Euclidean distance, etc. can be obtained respectively, and the absolute value of the difference, the square of the difference or the Euclidean distance can be determined as each difference information.

[0072] In step S210 , the server determines whether there is at least one difference information among the difference information that is greater than a difference threshold.

[0073] Here, the difference threshold can be a default value or a custom value. For example, the difference threshold can be 10, 15, etc.; if it is determined that the difference information is greater than the difference threshold, it indicates that the door body is not in a closed state, and the process goes to step S211, that is, it is determined that the door body is in an open state; if it is determined that the difference information is less than or equal to the difference threshold, it indicates that the door body is in a closed state, and the process goes to step S213 to continue to judge the state of the human body.

[0074] In step S211, the server determines that the door is in an open state.

[0075] At this time, the difference information is greater than the difference threshold, indicating that the door body is not in a closed state, and thus, the door body is in an open state.

[0076] In step S212, the server determines that the call termination condition is met and terminates the door opening call.

[0077] Here, when the door body is in the open state, the purpose of the door opening call has been achieved. Therefore, it is determined that the call end condition is met at this time, and the door opening call is ended.

[0078] In step S213 , the server performs image recognition on each video frame image to obtain each first recognition result.

[0079] Here, each first recognition result is used to indicate whether each video frame image contains a human body image. Image recognition can be performed on each video frame image using methods such as neural networks, wavelet moments, and fractal features to obtain each first recognition result for each video frame image.

[0080] In step S214 , the server determines whether each first recognition result indicates that each video frame image does not contain a human body image.

[0081] Here, if it is determined that each video frame image in each first recognition result does not contain a human image, it indicates that there is no visitor outside the door at this time, and the process goes to step S218; if it is determined that at least one video frame image in the first recognition result contains a human image, it indicates that there is still a visitor outside the door at this time, and the state of the human body is further determined, and the process goes to step S215.

[0082] In step S215 , the server determines the video frame image containing the human body image as the target video frame image.

[0083] Here, if there is a video frame image containing a human body image, then the video frame image containing the human body image is determined as a target video frame image, as the video frame image that needs to be further analyzed next.

[0084] In step S216 , the server determines the direction of movement of the human body based on the time information and distance information of each target video frame image.

[0085] Here, the information of each target video frame image includes the time information of the video frame image and the distance information of the human body from the image acquisition device. The server can obtain the time information and distance information from each target video frame image by reading the instruction. Furthermore, if the distance between the human body and the image acquisition device increases with time, the direction of human movement is determined to be moving away from the image acquisition device; if the distance between the human body and the image acquisition device remains essentially unchanged or increases with time, the direction of human movement is determined to be moving toward the image acquisition device.

[0086] In step S217, the server determines whether the human body is moving in a direction away from the image acquisition device.

[0087] Here, when the direction of movement of the human body is moving away from the image acquisition device, step S218 is entered, which indicates that the state of the human body is leaving; if the human body does not move or the direction of movement is moving towards the image acquisition device, step S206 is returned to, that is, the door opening call is continued to be initiated to the target terminal.

[0088] In step S218, the server determines that the human body is in the away state.

[0089] At this time, it is determined that there is no human image outside the door or the human body is leaving, that is, there is no visitor outside the door or the visitor is leaving, then, the state of the human body is determined to be the leaving state, indicating that the visitor has given up the visit, then, it can return to step S212, that is, determine that the call end condition is met at this time, and end the door opening call.

[0090] Through the above steps S201 to S218, the doorbell sends the received pressing operation to the server. In response to the pressing operation, the server obtains the video data currently collected by the image acquisition device and intercepts the video data into multiple video frame images. Next, the server performs image recognition on the video frame images within a preset time period. If the recognition result indicates that at least one video frame image contains a human image, the server determines that the call condition is met and initiates a door opening call to the target terminal. Then, during the call process, the server also obtains a reference feature indicating that the door is in a closed state, extracts the image features of each video frame image, and determines the difference information between each image feature and the reference feature. If the difference information is greater than the difference threshold, it is determined that the door is in an open state, and the call end condition is determined to be met, and the door opening call is terminated. If the difference information is less than or equal to the difference threshold, it is determined that the door is in a closed state, and further identifies whether the video frame image contains a human image. If the video frame image does not contain a human image or the human body is away from the image acquisition device, it is determined that the human body is in a leaving state, and the call end condition is determined to be met, and the door opening call is terminated. If the video frame image contains a human image, the door opening call is continued to be initiated to the target terminal. Therefore, before initiating the door opening call, it is possible to intelligently determine whether to initiate the door opening call based on whether the human body is in the away state, and not initiate the door opening call to the target terminal when the human body is in the away state; in addition, during the call process, it is also possible to continue to intelligently determine whether to continue to initiate the door opening call based on whether the door body is in the open state and whether the human body is in the away state, and the door opening call can be ended when the door body is in the open state or the human body is in the away state, thereby avoiding disturbing the homeowner and realizing intelligent calling.

[0091] Based on the above embodiment, the embodiment of the present application provides another doorbell hang-up interaction method, which can be applied to the doorbell, the server and the target terminal, and can automatically end the call during the call, such as Figure 3 As shown, the method includes:

[0092] Step S301: The target terminal sends a call permission instruction to the server.

[0093] Here, the call permission instruction may be a pressing instruction for “answer” or a voice “answer” instruction; then, the target terminal sends the call permission instruction to the server through the established communication connection.

[0094] Step S302: The server establishes a call connection between the doorbell and the target terminal.

[0095] Here, the server can establish a call connection between the doorbell and the target terminal by enabling the communication pin between the doorbell and the target terminal, so that the doorbell and the target terminal can conduct an audio and video call based on the call connection.

[0096] Step S303: The doorbell collects target video data through an image acquisition device during the call.

[0097] Here, the doorbell is provided with an image acquisition device. During a call, the doorbell can control the image acquisition device to acquire video data of the actual situation outside the door. Here, the video of the actual situation outside the door is recorded as target video data.

[0098] Step S304: The doorbell sends the target video data to the server.

[0099] Here, based on the existing communication connection between the doorbell and the server, the doorbell sends the collected target video data to the server.

[0100] In step S305, the server determines whether the door body is in an open state based on the target video data until a preset number of determinations is reached, and obtains each determination result.

[0101] Here, in order to ensure the accuracy of the judgment result, the target video data will be judged multiple times, that is, a preset number of judgments will be performed, wherein the preset number of judgments can be 5, 6, 7, etc.

[0102] In the embodiment of the present application, taking a judgment process as an example, the server has obtained the target video data through the above steps. Then, the server can intercept the video frame image corresponding to the target video data, extract the features of the target image, and then obtain the target difference information between the target image feature and the reference feature. When the target difference information is less than or equal to the difference threshold, the door is judged to be in the closed state; when the difference information is greater than the difference threshold, the door is judged to be in the open state. In this way, a judgment is completed and a judgment result is obtained. According to a similar judgment method, the judgment process is performed a preset number of times to obtain each judgment result.

[0103] In some embodiments, a door closer may be provided on the door. Still taking a single determination process as an example, the door closer can be in two states: closed and open. The server can directly read the state of the door closer. When the door closer is read as closed, the server determines that the door is in the closed state; when the door closer is read as open, the server determines that the door is in the open state. This completes a single determination, resulting in a single determination result. This determination process is repeated a predetermined number of times using a similar determination method to obtain each determination result.

[0104] In step S306, the server determines the number of times the door is in the open state in each judgment result.

[0105] Here, taking the preset number of determinations as 5 as an example, if the 5 determination results are all that the door is in the open state, the number of determinations determined by the server is 5.

[0106] Step S307: The server determines whether the number of times reaches a threshold.

[0107] Here, the number of times threshold is less than or equal to the preset number of times. Assuming the number of times threshold is 5, continuing with the above example, the number of times is also 5, indicating that the number of times is equal to the number of times threshold, that is, the number of times reaches the number of times threshold, and then proceeds to step S308; assuming the number of times threshold is 5, the number of times determined by the server is 3, indicating that the number of times is less than the number of times threshold, that is, the number of times does not reach the number of times threshold, and then proceeds to step S310.

[0108] Step S308: The server determines that the door is in an open state.

[0109] Here, when the number of times reaches the number threshold, it indicates that the door is in an open state.

[0110] Step S309: The server determines that the call termination condition is met and terminates the call connection.

[0111] Here, the purpose of the call connection is to open the door. When it is determined that the door is in an open state, it indicates that the purpose of the call connection has been achieved. Then, the call connection can be automatically ended, thereby improving the intelligence and automation level of the call.

[0112] Step S310: The server determines that the call termination condition is not met and maintains the call connection.

[0113] Here, when it is determined that the door is in a closed state, it indicates that the purpose of the call connection has not been achieved, so it is determined that the call termination condition is not met at this time, and the call connection is still maintained.

[0114] In some embodiments, the call connection can also be ended by:

[0115] Based on the call permission instruction sent by the target terminal, the server establishes a call connection between the doorbell and the target terminal. The server then obtains audio information from the call. The doorbell and the target terminal may be equipped with a sound collection device that can collect the audio of the call between the visitor and the homeowner and transmit the collected audio to the server. Finally, the server determines whether the audio information contains a preset target closing phrase and, if so, terminates the call. The preset target closing phrase may be phrases such as "goodbye," "see you later," or "come in," and generally appears at the end of the call. The server can use pattern matching to match the audio information with the target closing phrase to determine whether the audio information contains the target closing phrase. If so, the server terminates the call if it does. If not, the server continues the call, thereby intelligently terminating the call.

[0116] Through steps S301 to S310, the target terminal sends a call permission instruction to the server, and the server establishes a call connection between the doorbell and the target terminal based on the call permission instruction; then, during the call, the doorbell collects target video data through the image acquisition device and sends the target video data to the server; then, the server judges whether the door body is in an open state based on the received target video data, wherein the judgment is performed a preset number of times to obtain each judgment result; the server continues to determine the number of times that the door body is in an open state in each judgment result; finally, when the server judges that the number reaches the number threshold, it determines that the door body is in an open state and ends the call connection, so that the state of the door body can be accurately identified through multiple judgment results, and when it is determined that the door body is in an open state, the call connection is automatically ended, thereby improving the intelligence and automation level of the call.

[0117] Based on the above embodiment, the embodiment of the present application further provides a method for hanging up a smart doorbell, which is applied to a smart doorbell system and can realize audio and video calls. The audio and video call architecture 400 is as follows: Figure 4As shown, it includes three parts: communication terminal 401, communication platform 402 and artificial intelligence (AI) capability platform 403. Among them, communication terminal 401 can be a smart doorbell 4011 or a speaker, mobile phone 4012, etc. By linking the smart doorbell with terminals such as speakers and mobile phones, users can view the door situation in real time and have real-time conversations with visitors remotely. The communication platform 402 adopts a signaling and media separation strategy. The signaling module 4021 mainly handles call logic such as calling, talking, and hanging up, and the media module 4022 mainly processes audio and video stream data. The AI ​​capability platform mainly processes the video stream during calls or conversations and returns the results. Here, human detection 4031 can detect whether there is a person in the video stream through a deep learning algorithm, and open / close door detection 4032 can detect whether the door is opened through an image processing algorithm. The image processing algorithm can compare video images over a period of time. If the image difference exceeds a threshold, it is considered that the door is opened, that is, the door has been moved during the period.

[0118] In some embodiments, the communication platform and the AI ​​capability platform may be integrated into the same server or into different servers.

[0119] In the actual use of the smart doorbell, the hang-up method provided in the embodiment of the present application can realize the following three hang-up processes: the first is that when the smart doorbell initiates a door opening call, it can automatically end the door opening call; the second is that when the communication platform initiates a door opening call to the called terminal, it can automatically end the door opening call; the third is that during the call between the caller and the called party, the call is automatically hung up.

[0120] The first one is that when the smart doorbell initiates a door opening call, it can automatically end the door opening call. In the embodiment of the present application, the first hang-up process is as follows: Figure 5 As shown:

[0121] Step S501, start.

[0122] Step S502: The visitor presses the smart doorbell button.

[0123] Here, the smart doorbell is able to detect the action of pressing itself.

[0124] Step S503: The audio and video call process is activated, and the smart doorbell initiates the call.

[0125] After the user presses the smart doorbell, the smart doorbell can activate its own audio and video call process based on the pressing operation, prepare for subsequent audio and video calls, and the smart doorbell also initiates a door opening call to the communication platform.

[0126] Step S504: The communication platform receives a call request.

[0127] Here, after receiving the door opening call request, the communication platform does not send it to the device first, but continues to execute the following step S505.

[0128] In step S505, the communication platform captures the video images within a preset time period and sends them to the artificial intelligence capability platform.

[0129] Here, the preset duration can be 1 second, 2 seconds, etc. The communication platform can capture the video image within 1 second and send it to the AI ​​capability platform.

[0130] Step S506: The artificial intelligence capability platform returns the detection result.

[0131] Here, the AI ​​capability platform uses intelligent algorithms to detect whether there is someone at the door and returns the result to the communication platform.

[0132] In step S507, the communication platform determines whether there is anyone within the monitoring range based on the detection result.

[0133] The communication platform determines whether there is someone at the door based on the results returned by the AI ​​capability platform. If there is no one at the door, the call is stopped and the process goes to step S509. Otherwise, if there is someone at the door, the communication platform initiates a door opening call to the target terminal and the process goes to step S508.

[0134] Step S508: initiate a door opening call.

[0135] Step S509: Stop the door opening call.

[0136] Step S510, end.

[0137] Through the above steps S501 to S510, when a visitor presses the smart doorbell, the smart doorbell initiates a door-opening call to the communication platform. After receiving the door-opening call request, the communication platform does not send it to the target device first. Instead, it captures a video image within a preset time period and sends it to the AI ​​capability platform. Next, the AI ​​capability platform uses an intelligent algorithm to detect whether there is someone at the door and returns the detection result to the communication platform. The communication platform then determines whether there is someone at the door based on the returned detection result. If there is no one at the door, the call stops. If there is someone at the door, the communication platform initiates a door-opening call to the target terminal. Through human body detection technology, it analyzes whether there is someone at the door. If there is no one at the door, the smart doorbell stops initiating the call, thus avoiding the problem of initiating a door-opening call and disturbing the homeowner if someone accidentally presses the smart doorbell.

[0138] The second type is that the communication platform initiates a door opening call to the called terminal, and the door opening call automatically hangs up the process. In the embodiment of the present application, the second hang-up process is as follows: Figure 6 As shown:

[0139] Step S601, start.

[0140] Step S602: The communication platform initiates a door opening call to the target terminal.

[0141] Here, the target terminal can be a mobile phone or device bound to the user.

[0142] Step S603: Determine whether the user answers the call.

[0143] If the user has answered the door opening call, the process proceeds to step S604; if the user has not answered the door opening call, the process proceeds to step S605.

[0144] Step S604: Enter the call process.

[0145] Step S605: During the door opening call process, the communication platform captures an image at a set time interval and sends it to the artificial intelligence capability platform.

[0146] Here, the set duration can be 1 second, 2 seconds, etc. Taking 1 second as an example, the communication platform captures a picture every 1 second and sends it to the AI ​​capability platform, so that the AI ​​capability platform can detect the image.

[0147] Step S606: The artificial intelligence capability platform returns the detection results.

[0148] Here, the AI ​​capability platform uses intelligent algorithms to detect the status of the door, which can be open or closed, and whether there is someone at the door, and returns the results to the communication platform.

[0149] Step S607: The communication platform determines whether the door is opened.

[0150] If it is determined that the door is open, go to step S608; if it is determined that the door is not open, go to step S609.

[0151] Step S608: Stop the door opening call.

[0152] In step S609, the communication platform determines whether there is anyone within the monitoring range.

[0153] If there is someone within the monitoring range, the process returns to step S602 and continues to initiate a door opening call to the target terminal; if there is no one within the monitoring range, the process proceeds to step S610.

[0154] Step S610: Whether it is determined for a preset number of consecutive times that there is no one within the monitoring range.

[0155] Here, the preset number of times can be 5 times, 6 times, etc. Taking the preset number of times as an example, if it is judged that there is no one within the monitoring range for 5 consecutive times, return to step S608, that is, stop the door opening call; if there is at least 1 time that it is judged that there is someone within the monitoring range, return to step S602 and continue to initiate the door opening call to the target terminal.

[0156] Step S611, end.

[0157] Through steps S601 to S611, the communication platform initiates a door-opening call to the target terminal, then determines whether the user answers the call on the target terminal. If the user answers the call, the call proceeds. If the user does not answer the call, the call continues, capturing an image at set intervals during the call to determine whether the door is open and whether there is someone at the door. If the door is open, the call is terminated. If the door is closed, the platform repeatedly determines whether there is no one within the monitoring range. If the multiple determinations indicate that no one is within the monitoring range, the call is terminated. Using human detection technology, the platform analyzes whether there is someone at the door. If no one is at the door, the smart doorbell terminates the door-opening call. This means that if a visitor leaves the door due to the homeowner's lack of response during the call, the call can be stopped without disturbing the homeowner. Furthermore, using door open / close detection technology, the platform analyzes whether the door is open. If the door is open, the call is terminated. If the homeowner opens the door without answering the call, the call is automatically terminated.

[0158] The third type is a process in which the call is automatically hung up during the call between the calling party and the called party. In the embodiment of the present application, the third hang-up process is as follows: Figure 7 As shown:

[0159] Step S701, start.

[0160] Step S702: The homeowner is talking to the visitor.

[0161] Step S703: During the process, the communication platform captures an image at a set time interval and sends it to the artificial intelligence capability platform.

[0162] Here, the set time length can be 1 second, 2 seconds, etc. Taking 1 second as an example, the communication platform captures a picture every 1 second and sends it to the AI ​​capability platform, so that the AI ​​capability platform can detect the image.

[0163] Step S704: The artificial intelligence capability platform returns the detection results.

[0164] Here, the AI ​​capability platform uses intelligent algorithms to detect the status of the door, which can be open or closed, and whether there is someone at the door, and returns the results to the communication platform.

[0165] Step S705: The communication platform determines whether the door is opened.

[0166] If it is determined that the door is open, go to step S706; if it is determined that the door is not open, return to step S702.

[0167] Step S706: Determine whether the door is opened for a preset number of consecutive times.

[0168] Here, in order to avoid errors caused by this judgment result, a preset number of judgments is performed, wherein the preset number of times can be 5 times, 6 times, etc. Taking the preset number of times as an example, if the door is judged to be open for 5 consecutive times, it means that the purpose of the call has been achieved, the visitor can enter the room or building, and the process goes to step S707; if there is at least 1 judgment that the door is not opened and is still in a closed state, the process returns to step S702.

[0169] Step S707: Stop the call.

[0170] Step S708, end.

[0171] Through the above steps S701 to S708, during the conversation between the homeowner and the visitor, the communication platform captures an image at a set time interval and sends it to the AI ​​capability platform; then, the AI ​​capability platform detects the image and returns the detection result to the communication platform; then, the communication platform determines whether the door is open based on the detection result. If the door is not open, the conversation between the homeowner and the visitor continues; if the door is open, it continues to determine whether the door is open multiple times, and stops the conversation when multiple judgments indicate that the door is open. Through the open / closed door detection technology, it analyzes whether the door is open. If the door is open, the call is stopped. During the call, the homeowner goes directly to the door to open it. At this time, there is no need to continue the call, and the call can be automatically stopped, thereby improving the automation level of the call and improving the user experience.
