In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
It will be understood that the terms "comprises" and/or "comprising," when used in this specification and the appended claims, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
It should also be understood that the term "and/or" as used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.
Reference throughout this specification to "one embodiment" or "some embodiments," or the like, means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," or the like, in various places throughout this specification are not necessarily all referring to the same embodiment, but rather "one or more but not all embodiments" unless specifically stated otherwise.
The first embodiment is as follows:
at present, a user often uses the child telephone watch to record videos when wearing the child telephone watch, but in the recording process, if a shot main body is in a moving state, the user also needs to move an arm back and forth to align the shot main body, and the user moves the arm back and forth to cause picture shaking, so that the quality of the recorded videos is poor.
In order to solve the technical problem, an embodiment of the present application provides a video recording method, in which a wearable device adjusts a shooting angle of a camera on the wearable device according to a recording scene where the wearable device is currently located, and executes a recording action through the camera with the adjusted shooting angle, so as to obtain a recorded video.
Because the shooting angle of the camera of the wearable device can be automatically adjusted according to the recording scene of the wearable device and the video is recorded, the limb wearing the wearable device does not need to be moved back and forth by a user, the picture of the recorded video is prevented from shaking, and the quality of the recorded video is improved.
The following describes a video recording method provided in an embodiment of the present application with reference to the drawings.
Fig. 1 shows a flowchart of a video recording method provided in an embodiment of the present application, which is applied to a wearable device, and a shooting angle of a camera of the wearable device can be changed between an upper 180 degrees and a lower 180 degrees and a left 360 degrees and a right 360 degrees, for example, the camera can be directly controlled to rotate by a motor (e.g., a stepping motor) built in the camera, so as to ensure that the camera has each shooting angle, or the camera can be ensured to have each shooting angle by controlling the motor built in the camera and rotating a module (e.g., a dial plate of a child telephone watch) where the camera is located. 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 video recording method provided by the embodiment of the application is detailed as follows:
and step S11, if a video recording command is received, controlling the camera of the wearable device to execute a shooting action.
In this embodiment, the camera executes a shooting operation to obtain a shot image.
In this embodiment, the user can send a video recording command by directly pressing a key for recording a video in the wearable device.
In some embodiments, if the wearable device is equipped with a microphone, the video recording command can be spoken by voice. Specifically, the wearable device detects whether the voice is received through the microphone, recognizes the received voice through a voice recognition algorithm to obtain a voice recognition result, and judges whether a video recording 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 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 command to the wearable device through the mobile phone, for example, the user sends the video recording command to the wearable device by pressing a designated key of the mobile phone.
In some embodiments, if the lens of the camera in the wearable device faces upward (towards the sky) before the wearable device receives the video recording command, the camera is flipped up first and then the shooting action is performed. It should be noted that after the camera is turned up, the lens of the camera is usually not facing upward any more, but under the driving of the motor, the lens of the camera can also face upward to ensure that the camera has various shooting angles. In this embodiment, since the person to be recorded is not usually above the lens, the shooting operation is performed after the camera is turned up, and a more accurate image can be obtained.
And step S12, determining a recording scene through the image shot by the camera.
In this embodiment, scene characteristics of different recording scenes are preset. After the image is shot by the camera, the wearable device extracts the features contained in the image shot by the camera, compares the analyzed features with the preset scene features of each recording scene, and judges that the recording scene where the character to be recorded is located is the certain recording scene if the analyzed features are matched with the scene features of the certain recording scene.
For example, assume a basketball game scenario has scenario features including: the basketball game method comprises the steps that a basketball hoop, N (N is larger than 1) persons, target actions (such as running, dribbling, passing, shooting and the like) exist in the N persons, and if the characteristics contained in an image shot by a camera are analyzed to be matched with the scene characteristics of the listed basketball game scenes, the recorded scene where the character to be recorded is located is judged to be the basketball game scene.
And step S13, adjusting the shooting angle of the camera according to the recording scene.
In this embodiment, the shooting angle of wearing equipment to the camera according to recording the scene adjusts, for example, to recording scene 1, the motor control camera is with first speed from left to right translation, and to scene 2, the motor control camera is with second speed from the top down or from the bottom up rotation. In this embodiment, because the user often has different shooting requirements in different recording scenes, the shooting angle of the camera is correspondingly adjusted according to the difference in the recording scenes, and the accuracy of the recorded video can be improved.
And step S14, executing recording action according to the camera adjusted by the shooting angle to obtain a recorded video.
In this embodiment, during and after the adjustment of the shooting angle of the camera, the camera will continue to perform the recording operation, and the recording of the video will not be stopped until the recording ending command is received, so as to obtain the recorded complete video.
In the embodiment of the application, after receiving a video recording command, the wearable device controls the camera to execute a shooting action, performs scene recognition according to an image obtained by the camera, adjusts the shooting angle of the camera according to the recognized recording scene, and executes the recording action according to the camera adjusted by the shooting angle to obtain a recorded video. Because wearing equipment can carry out the adjustment that corresponds to the shooting angle of camera according to the scene of recording that its discernment obtained, consequently, make the camera after the shooting angle adjustment more be fit for recording the scene of recording that wearing equipment is current to be located, thereby guarantee that wearing equipment records the video more accurate. In addition, because the video is recorded by adjusting the shooting angle of the camera, the user does not need to move the limb wearing the wearable device back and forth, so that the picture of the recorded video is prevented from shaking, the stability of the recorded video is improved, and the quality of the recorded video is improved.
Fig. 2 shows a flowchart of another video recording method provided in this embodiment of the present application, and in this embodiment, a ball game scene is taken as an example for description, and step S21, step S22, and step S25 are respectively the same as step S11, step S12, and step S14, and are not repeated here.
And step S21, if a video recording command is received, controlling the camera of the wearable device to execute a shooting action.
And step S22, determining a recording scene through the image shot by the camera.
Step S23, if the recorded scene is a ball game scene, selecting a corresponding camera control strategy according to the ball game scene, where the camera control strategy includes tracking balls and contacts of the balls.
In this embodiment, it is considered that in the ball game, players on the field need to run back and forth on the field, and win and loss of the ball game are related to the position of the ball. For example, assuming that the ball game is a basketball game, the win-or-loss of the basketball game is related to whether the basketball is thrown into the basket, that is, when the user watches the basketball game, the user usually focuses on the basketball, the ball sender and the ball receiver, and therefore, in the embodiment of the present application, the camera control strategy corresponding to the ball game scene is set to include the ball and the ball contact person, which is beneficial to more accurately controlling the shooting angle of the camera in the following process.
And step S24, adjusting the shooting angle of the camera according to the camera control strategy.
In this embodiment, in the process of performing the track shot on the ball and the ball contact person, if it is recognized that the ball contact person runs with the ball, the lens of the camera is controlled to be aligned with the ball contact person or aligned with the basketball. If the fact that a contact person of the ball is to pass is identified, the motion trail of the ball is determined, the moving direction and the distance of the ball are predicted according to the motion trail of the ball, and finally the shooting angle of the camera is adjusted according to the prediction result (the moving direction and the distance) so that the lens of the camera is aligned to the pre-judged direction where the ball is passed, and the ball after being passed can be locked quickly.
And step S25, executing recording action according to the camera adjusted by the shooting angle to obtain a recorded video.
In some embodiments, the ball or the contacter of the ball is kept in the center of the picture in the video recorded by the camera, so that the subsequent user can more clearly view the video of the ball or the contacter of the ball.
In the embodiment of the application, the camera control strategy corresponding to the ball game scene comprises the contact persons tracking balls and balls, and the wearable device adjusts the shooting angle of the camera according to the camera control strategy, so that the camera in the shooting angle adjustment and after the shooting angle adjustment can be ensured to be aligned to the contact persons of the balls or the balls in time, and the quality of the shot ball game video can be improved. Meanwhile, manual intervention is not needed, so that the convenience in recording the ball game video is greatly improved.
In some embodiments, the video recording method further includes:
and A1, predicting the action of the contacter in the process of recording the video.
In this embodiment, in the process of tracking a ball, if it is detected that the ball is in a hand of a player, each skeletal key point of the player in a plurality of adjacent image frames is obtained through a preset human skeletal key point detection algorithm, and an action to be performed by the player is predicted according to each obtained skeletal key point.
And A2, if the predicted action of the contacter is the target action, adjusting the shooting parameters of the camera.
In this embodiment, the shooting parameters include a magnification, and after the magnification of the camera is amplified, the proportion of the contact person in the picture is amplified, so that a user can conveniently view the action details of the contact person; on the contrary, the proportion of the contact person in the picture is reduced, but the shooting range is expanded, so that the user can conveniently check the actions of the competition personnel in a large range.
In some embodiments, if the predicted motion of the contact person is not the target motion, the shooting angle of the camera may be adjusted according to a camera control strategy without adjusting the shooting parameters of the camera. For example, if the predicted action of the contacter is a pass action, the orientation of the ball after passing is predicted, and the shooting angle of the camera is adjusted according to the predicted result, so that the lens of the camera is aligned with the predicted orientation of the ball after passing.
Correspondingly, the step S25 includes:
and executing a recording action according to the camera with the adjusted shooting angle and the adjusted shooting parameters to obtain a recorded video.
In this embodiment, for example, if the shooting parameter includes a magnification, the video is recorded with the adjusted magnification, and a video with a corresponding magnification is obtained.
In the above-mentioned a1 to a2, since the magnification of the camera is adjusted according to the predicted movement of the contacter, the recorded video has different magnifications, that is, the user can view the video with different magnifications, thereby improving the user's experience.
In some embodiments, the ball game scenario is a basketball game scenario, and the a2 includes:
and a21, if the target motion is a pitching motion, reducing the magnification of the camera.
For example, the camera with the reduced magnification can shoot a basketball and a contact person at the same time.
And a22, if the target motion is taken as the basket-up motion, magnifying the magnification of the camera.
The above-mentioned upper basket is also called a take-out basket, that is, an action of directly delivering a ball to a basket by a player, and the shooting is an action of not directly delivering a ball to a basket by a player.
In the embodiment, in an actual viewing scene, when a player shoots a basketball, the spectator usually needs to move the sight line so as to track the basketball at a larger visual angle, and then can watch whether the shot basketball enters the basket or not in time; when the players play, the spectators usually want to be able to check the fine movements of the players, so the a21 and a22 select the zoom-out or zoom-in magnification of the camera according to whether the player plays the ball or plays the basket, that is, the ratio and position of the players on the picture are specifically adjusted, so as to ensure that the video more meeting the user's requirements is obtained, capture the details of the movements of the players in close-up, and enable the picture to have more impact force.
In some embodiments, the step S21 (step S11) includes:
and if a video recording command is received and the video recording command indicates that the current recording mode of the wearable device is a specified mode, controlling a camera of the wearable device to execute a shooting action.
In this embodiment, the recording mode of the wearable device has at least 2 modes: a designated mode and a non-designated mode. When a user needs to record a video, the video recording mode is selected first, and the wearable device executes corresponding actions according to the recording mode selected by the user. For example, when the recording mode selected by the user is the designated mode, the camera is controlled to execute the shooting action, so that the scene can be analyzed according to the shot images.
In some embodiments, the controlling the camera of the wearable device to perform a shooting action includes:
and controlling the camera of the wearable device to be turned up, and respectively executing shooting actions at least 2 different shooting angles.
In this embodiment, accessible motor drive camera is turned up to guarantee that this camera has better visual angle and treats the shooting main part and shoot.
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 the child telephone wristwatch includes a dial, a support plate, and a band, the dial being on the support plate, and both ends of the support plate being connected to the band. When the camera of this children's phone wrist-watch is not used, the both ends of this dial plate all contact with the both ends of layer board, and the screen of dial plate is parallel with the plane at layer board place, and when the dial plate turn-up back, only one end of this dial plate contacts with the one end of layer board, and the screen of dial plate no longer is parallel with the layer board.
In the present embodiment, since the photographing actions are performed at least 2 different photographing angles, respectively, at least 2 images can be obtained. Compared with the method for analyzing only one image, the method for analyzing the plurality of images can obtain a more accurate scene recognition result after the plurality of images are analyzed subsequently.
In some embodiments, the performing the shooting actions at least 2 different shooting angles respectively includes:
and controlling the camera to rotate from the left side of the basketball court to the right side of the basketball court, and shooting a plurality of images.
Correspondingly, step S22 includes:
the method comprises the steps of combining a plurality of shot images into a complete image, then confirming whether a basket exists in a scene or not through image semantic segmentation and an image classification algorithm of deep learning, confirming whether the number of people in a field is close to the number of people in a basketball game or not, and if the basket exists and the number of people in the field is close to the number of people in the basketball game, judging that the recorded scene is the basketball game scene. In order to further improve the accuracy of the obtained judgment result of the recorded scene, whether actions such as running, dribbling, passing, shooting and the like exist in the field personnel is identified through a human skeleton key point technology, and if the actions exist, the current recorded scene is considered as a basketball game scene.
In some embodiments, the video recording method further comprises:
and if a video recording command is received and the video recording command indicates that the current recording mode of the wearable device is a non-specified mode, directly recording the video.
In this embodiment, when the wearable device determines that the current recording mode is the non-specific mode, the video recording is directly performed without performing a shooting operation or recognizing a scene, so that the video recording can be quickly performed.
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.
