The following describes a tracking shooting method provided in an embodiment of the present application with reference to the drawings.
Fig. 1 shows a flowchart of a tracking shooting method provided in an embodiment of the present application, and the method is applied to a wearable device. In this embodiment, the shooting angle of the camera of the wearable device can be changed between up and down 180 degrees and left and right 360 degrees. Because this camera has each shooting angle, consequently for the shooting scope of this camera is wider, thereby makes wearing equipment keep flat and also can realize omnidirectional shooting on the desktop. The tracking shooting method of the embodiment of the application is detailed as follows:
in step S11, if a video recording start command is received, the subject to be photographed is determined.
In this embodiment, if the wearable device is equipped with a microphone, the wearable device may detect whether a voice is received through the microphone, recognize the received voice through a voice recognition algorithm to obtain a voice recognition result, and determine whether a video recording start command is received according to the voice recognition result. For example, assuming that the wearable device recognizes that the voice includes information of "record video", it is determined that a video start recording command is received.
In some embodiments, if the wearable device establishes a connection (e.g., a bluetooth connection) with another terminal device (e.g., a mobile phone), the user may send a video recording start command to the wearable device through the mobile phone, for example, the user sends the video recording start command to the wearable device by pressing a designated key of the mobile phone.
It should be noted that the user who issues the video recording start command and the subject to be photographed may be the same user. For example, after the user places the wearable device on a desktop, a certain distance is kept between the wearable device and the user, and then a video recording start command is sent out through voice.
And step S12, controlling a lens of a camera of the wearable device to face the subject.
In this embodiment, after receiving a video recording start command, the wearable device controls the camera of the wearable device to rotate through a motor built in the wearable device, so that the lens of the rotated camera faces the subject to be photographed (that is, the photographing direction of the camera is the direction in which the subject to be photographed is located), and thus, the subject to be photographed can be photographed through the camera subsequently.
And step S13, tracking and shooting the subject to be shot to obtain a recorded video.
In this embodiment, the subject to be photographed may be tracked and photographed by a preset target tracking algorithm to obtain a recorded video.
In the embodiment of the application, after the wearable device receives the video recording starting command, the main body to be shot is determined, the lens of the camera of the wearable device is controlled to face the main body to be shot, and the determined main body to be shot is tracked and shot through the camera, so that the recorded video is obtained. When the video is recorded, the camera is not required to be manually controlled by a user to align to the main body to be shot, and the camera can track and shoot the main body to be shot, so that the operation of the user is greatly reduced, the operation time of the user is not required to be consumed, and the good experience of the user is improved.
In some embodiments, if the video recording start command is issued by voice, the determining of the subject to be photographed in step S11 includes:
and determining the subject which sends the voice as the subject to be shot.
In this embodiment, a plurality of microphones may be provided on the wearable device, the plurality of microphones forming a microphone array. Through the microphone array and the sound source positioning algorithm, the specific direction of the main body emitting the voice relative to the wearable device is identified, and the main body is determined as the main body to be shot.
It should be noted that the number of subjects to be photographed may be 1, 2, 3, or the like, for example, when there are a plurality of subjects which utter voice, there are a plurality of determined subjects to be photographed; for example, a subject who utters a voice and a subject whose distance from the subject who utters the voice is a preset range are both determined as subjects to be photographed, and the like.
In some embodiments, considering that the wearable device is a personal article, which is generally only used by a limited number of users, in order to prevent others from activating the wearable device at will, before the subject who utters the voice is determined as the subject to be photographed, the method includes:
and identifying whether the user who utters the voice is a legal user.
The determining of the subject who utters the voice as the subject to be photographed includes:
and if the user is the legal user, determining the main body which sends the voice as the main body to be shot.
In this embodiment, one or more legal users are set on the wearable device in advance, after receiving a voice, the voice feature of the voice is extracted, the voice feature is compared with the voice feature of the legal user, if the voice feature is the same as the voice feature of the legal user, the user who sent the voice is determined to be a legal user, and otherwise, the user who sent the voice is determined to be an illegal user. Because different users have different sound characteristics, whether the user who utters the voice is a legal user can be accurately identified through the sound characteristics.
In this embodiment, if the wearable device determines that the user who uttered the voice is an illegal user, the wearable device does not respond to the voice, for example, the subject who uttered the voice is not determined as the subject to be photographed. Because wearing equipment just can confirm the main part of pronunciation as waiting to shoot the main part after the user who discerns out pronunciation is legal user, consequently, can avoid this wearing equipment false response illegal user to improve the degree of accuracy that this wearing equipment responded.
In some embodiments, if the video recording start command is issued to the wearable device through the terminal device, the determining of the subject to be photographed in step S11 includes:
if the connection between the terminal device and the wearable device is bluetooth connection, the wearable device may determine the location of the terminal device through an Angle of Departure (AOD) or Angle of Arrival (AOA), and determine the subject at the location of the terminal device as the subject to be photographed.
In this embodiment, since the terminal device can send a video recording start command, and the subject to be photographed can be determined by AOD or AOA, the flexibility of determining the subject to be photographed is improved.
In some embodiments, the number of the cameras of the wearable device is greater than 1, and there are at least 2 cameras with different resolutions in each of the cameras, and the controlling the camera of the wearable device to be flipped up and to be directed to the subject to be photographed includes:
and controlling the camera with the highest resolution in the wearable device to turn up, and enabling the lens of the camera with the highest resolution to face the subject to be shot.
In this embodiment, assume that the wearable device has 2 cameras, which are a front camera and a rear camera, respectively, and the resolution of the rear camera is higher than that of the front camera, then the subject to be shot is shot through the rear camera (i.e. the camera with the highest resolution) to obtain a video with higher resolution.
In this embodiment, the camera can be driven by the motor to be turned up, so that the camera can be ensured to have a better visual angle to shoot a subject.
Of course, if the wearable device is a child telephone watch, and the camera of the child telephone watch is integrated with the dial plate, the motor can control the camera on the dial plate to turn up by controlling the dial plate to turn up. It should be noted that, when the camera of the child telephone watch is not used, both ends of the dial of the child telephone watch are respectively connected with both ends of the watchband, and after the dial is turned up, only one end of the dial is connected with one end of the watchband, and the other end of the dial is not connected with any object.
In some embodiments, after the step of controlling the camera with the highest resolution in the wearable device to be turned up and directing the lens of the camera with the highest resolution to the subject to be photographed, the method includes:
outputting prompt information, wherein the prompt information comprises: information that the subject to be photographed has been locked.
In this embodiment, the output prompt information includes the information that the subject to be photographed is locked, so that a user (such as the subject to be photographed) can timely know whether the wearable device is ready to photograph, thereby facilitating recording of a more accurate video.
In some embodiments, the number of subjects to be photographed may be 1, 2, 3, or the like. Correspondingly, the prompt message may be: 1 subject to be photographed has been locked, 2 subjects to be photographed has been locked, and 3 subjects to be photographed has been locked, etc.
In some embodiments, the step S13 includes:
and A1, tracking and shooting the subject to be shot.
And A2, stopping recording if a video recording stopping command is received, and obtaining a recorded video.
In the above-mentioned a2, the video stop recording command is issued in a similar manner to the video start recording command. For example, the video recording stop command may be issued by voice — when the wearable device determines that the received voice includes information indicating that video recording is to be stopped, the wearable device determines that the video recording stop command is received. For example, the video recording stop command may be issued by a terminal device that establishes a connection (e.g., a bluetooth connection) with the wearable device.
In this embodiment, because the wearable device can stop recording when receiving the video recording stop command, the timeliness of stopping recording the video can be improved, and the accuracy of the obtained video is improved.
In some embodiments, before the step a1, the method further comprises:
and detecting whether the subject to be shot is completely included in the recorded picture.
Correspondingly, the step a1 includes:
and tracking and shooting the subject to be shot if the subject to be shot is completely included in the recorded picture.
In this embodiment, if the subject to be photographed is a person, the accurate position of the face of the person to be photographed can be found through a neural network face recognition algorithm, the face of the subject to be photographed is locked, and then the lens direction of the camera is finely adjusted through the motor and the picture proportion of the camera is adjusted, so that the subject to be photographed is completely included in the recorded picture, and the quality of a subsequently obtained video is improved.
Further, in order to achieve a better recording effect, the subject to be photographed is always kept at the center of the picture.
In some embodiments, after obtaining the recorded video, the method further comprises:
and B1, adjusting the dial of the wearable device, so that the adjusted screen of the dial faces the subject to be shot.
And B2, automatically playing back the recorded video.
In the above-described B1 and B2, since the screen on the control dial is directed toward the subject to be photographed, the user can easily view the played back video from the screen without changing the orientation.
In some embodiments, if the camera with the highest resolution is disposed on the back side of the dial (the front side of the dial is provided with the screen), after the video is recorded by using the camera with the highest resolution, the dial needs to be rotated by the motor, and the recorded video is automatically played back until the screen on the front side of the dial faces the subject to be photographed, so that convenience of viewing the recorded video by a user can be greatly improved. For example, assuming that a subject to be photographed issues a video recording stop command through voice, the child telephone watch recognizes the orientation of the subject (or a subject whose sound characteristics satisfy conditions) that utters the voice with respect to the wearable device through the array microphone, adjusts the angle of the dial plate so that the front of the adjusted dial plate faces the subject to be photographed determined according to the voice, and finally automatically plays back the recorded video.
In some embodiments, the tracking shooting method further includes:
if the automatic playback of the recorded video is finished, or if a playback stopping instruction is received, the dial plate of the wearable device is adjusted again, so that the screen of the dial plate which is adjusted again is restored to the state when the video is not recorded.
In this embodiment, because when playback video, the dial plate still is in the turn-up state, and this dial plate still has one end to link together with the watchband promptly, consequently, when no longer needing the playback, through motor adjustment dial plate for the both ends of this dial plate link together with the both ends of watchband again, can reduce user's operational load, thereby improve user's good experience.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
