Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The flow diagrams depicted in the figures are merely illustrative and do not necessarily include all of the elements and operations/steps, nor do they necessarily have to be performed in the order depicted. For example, some operations/steps may be decomposed, combined or partially combined, so that the actual execution sequence may be changed according to the actual situation.
Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
With the rapid development of terminal technology, photographing terminals having a camera function, such as a mobile phone, a video camera, etc., have become very popular. At present, the shooting terminal is mainly controlled to shoot in a mode of manual key pressing of a user, and a photographer cannot shoot the terminal at a long distance in a contact control mode. In order to perform long-distance shooting, shooting can be performed by a selfie stick, but in practice, the shooting distance is limited. The imaging purpose can be achieved by setting the interval time of self-imaging, but it is not easy to grasp the optimum imaging time and to perform random control.
In view of this, the embodiment of the present application provides a scheme capable of controlling to perform shooting control remotely, which can recognize a gesture of a shot object, start a follow-up shooting mode if the gesture of the shot object is a preset gesture, use the shot object as a follow-up object, control a gesture of a pan-tilt according to position information of the follow-up object, and enable the follow-up object to be within a shooting range of a shooting terminal carried by the pan-tilt, thereby implementing shooting control remotely without contacting the shooting terminal or the pan-tilt, and enable the follow-up object to be within the shooting range of the shooting terminal carried by the pan-tilt, and the shooting process is not limited to a fixed composition.
The shooting control method provided by this embodiment may be implemented by software, or by a combination of software and hardware, or by hardware, where the related hardware may be composed of two or more physical entities, or may be composed of one physical entity. The application scene of the method relates to the cloud deck and the shooting terminal carried by the cloud deck, and the shooting range of the shooting terminal carried by the cloud deck can change along with the change of the posture of the cloud deck. The holder and the shooting terminal can be mutually independent equipment or an integrated machine integrated with the holder and the shooting terminal.
The shooting terminal is carried on the cloud platform, can communicate with the cloud platform for shoot. The shooting terminal can be a device with a shooting function, such as a smart phone, a smart learning machine, a tablet computer, a notebook computer, a Personal Digital Assistant (PDA), a camera, and a wearable device. The camera may be a quasi-professional camera, a consumer camera, or a consumer lens of the use of the camera, or the like.
The cloud platform can be the support equipment of installation, fixed shooting terminal, can be handheld cloud platform or fixed cloud platform. The cradle head can comprise an electronic speed regulator (called an electric regulator for short) and a motor, and the movement of the cradle head can be controlled through the electric regulator and the motor. The cradle head also can comprise a controller, and the controller is used for controlling the electric controller and the motor to control the motion of the cradle head. It is understood that the motor may be a dc motor or an ac motor. In addition, the motor may be a brushless motor, and may also be a brush motor, and the embodiment of the present application is not limited thereto. When the cloud platform is independent of the shooting terminal, the shooting terminal can control the posture of the cloud platform by sending a control command. When the holder and the shooting terminal are integrated machines, the controller of the holder can control the electric controller and the motor to realize the motion of the holder and the like.
For example, the pan/tilt head may be a three-axis pan/tilt head, that is, the pan/tilt head may rotate with the Yaw axis, Pitch axis, and Yaw axis of the pan/tilt head as axes, respectively. When the holder rotates by taking the Roll shaft as a rotating axis, the Roll angle of the holder changes, when the holder rotates by taking the Pitch shaft as the rotating axis, the Pitch angle of the holder changes, and when the holder rotates by taking the Yaw shaft as the rotating axis, the Yaw angle of the holder changes. When the cloud platform uses one or more in the Yaw axle, Pitch axle, the Yaw axle of cloud platform as the axis rotation, the rotation that the cloud platform was followed to the shooting terminal rotates for the shooting terminal can follow different shooting directions and shoot the angle and shoot following the object. For another example, the pan/tilt head may be a two-axis pan/tilt head, and the pan/tilt head may rotate on two rotation axes, i.e., pitch and roll, and the like.
In one example, the photographing control scheme may be applied to a photographing terminal, and the photographing control method may be implemented by photographing software in the photographing terminal, for example. As shown in fig. 1, the present application is an application scenario diagram of a shooting control method according to an exemplary embodiment. In this scenario, a camera terminal 110 (illustrated in fig. 1 as a smartphone) and a handheld pan/tilt head 120 are involved. The shooting control method can be executed by the shooting terminal 110, the shooting terminal 110 communicates with the handheld tripod head 120, and the posture of the tripod head can be controlled by sending a control instruction, so that the shooting range of the shooting terminal 110 can be changed along with the change of the posture of the handheld tripod head 120.
In another example, the shooting control method may also be applied to a pan/tilt head. The cradle head can be independent of the shooting terminal, the cradle head obtains a shooting image from the shooting terminal, the posture of the shot object is recognized, and if the posture of the shot object is a preset posture, the shooting terminal is controlled to start a follow-up shooting mode. The cloud platform also can constitute the all-in-one with the shooting terminal. The shooting control method is applied to the all-in-one machine. The all-in-one machine can comprise a processor, and the shooting control method can be realized by the processor.
The following describes an example of a shooting control method provided in the present application.
As shown in fig. 2A, fig. 2A is a flowchart of a photographing control method according to an exemplary embodiment shown in the present application, and the method may include the following steps 220 to 260:
in step 220, recognizing the gesture of the object;
in step 240, if the posture of the object is a preset posture, starting a follow-up shooting mode and determining that the object is a follow-up object;
in step 260, controlling the posture of the pan/tilt head according to the position information of the following object, so that the following object is in the shooting range of the shooting terminal carried by the pan/tilt head.
Wherein, the photographed object can be an object captured within a photographing range of the photographing terminal. Within the shooting range of the shooting terminal, there may be one subject or a plurality of subjects. In the case where a plurality of objects exist within the shooting range, the object to be shot may be an object at a specified position in the shot image, for example, an object in the middle area of the shot image. The object to be photographed may be any object, that is, each object in the photographing range is subjected to gesture recognition, and as long as a preset gesture is recognized, the follow-up photographing mode is started. It is understood that, in the case that a plurality of objects exist in the shooting range, the object to be shot may also be determined in other manners, for example, a specific object (an object having a control authority) may be used, so that shooting control can be realized only by realizing a posture of the specific object, and the like. The shooting may include taking a picture or taking a video, and the taking a video may be recording.
The posture may be a body posture, a gesture, or the like of the subject. The body posture may be a half-body posture or a full-body posture formed by one or more body parts; the gesture may be a gesture determined by a hand stroke. The preset posture may be a posture set in advance to instruct to start the follow-up photographing mode. The preset posture can be set by a software developer or can be set by a user independently. For example, the body posture may be a cross, a single foot standing, a hand lifting, a head shaking, a nodding, or the like. The gesture may be a "six" gesture, a bixin gesture, a "2" gesture (also known as a jersey gesture), an ok gesture, a like gesture, a palm open gesture, and the like, as well as gestures that stroke other numbers. As shown in fig. 2B, fig. 2B is a diagram illustrating several gestures according to an exemplary embodiment of the present application. It can be understood that the diagram only illustrates several gestures, and other gestures may be used in practice, which are not described herein. The preset posture may be one posture or a plurality of postures. In the case of a plurality of postures, each posture may be ordered or unordered. Taking a plurality of ordered gestures as an example, after the gesture of "3", the gesture of "2", and the gesture of "1" are sequentially recognized, the gesture of the photographic object is determined to be a preset gesture.
Regarding how to recognize the gesture, for example, a pre-trained gesture recognition model may be adopted for recognition, and the gesture recognition model may be obtained by training a neural network with a labeled training sample. It should be understood that, for recognizing the gesture, a recognition method in the related art may also be adopted, which is not limited herein.
In a case where the posture of the photographic subject is the preset posture, the follow-up photographing mode may be started, and the photographic subject may be determined as the follow-up subject.
The following shooting mode is a mode in which the following subject is subjected to following shooting. In one example, initiating the follow-up shot mode includes: a tracking service for tracking the following object is started, but a photographing operation is not performed. That is, only the tracking operation is triggered, and the photographing operation (photographing operation/image capturing operation) is not triggered. For example, the follow-up photographing mode may be a mode in a photographing or photographing service as opposed to a normal photographing mode. In the follow-up photographing mode, capturing of an image is started, and a follow-up subject is tracked from the captured image, but a photographing operation is not triggered. After the following shooting mode is started, if shooting or photographing is needed, corresponding shooting operation or photographing operation is executed when a shooting instruction or a photographing instruction is obtained. The shooting instruction or the photographing instruction can be triggered in a contact mode or in other postures different from the preset posture. And the camera shooting operation is triggered in the following shooting mode, so that the following object can be automatically recorded and shot. Under following the shooting mode, even if the user has changed the shooting position, because the cloud platform can adjust the shooting scope of shooing the terminal, make follow the object in the shooting scope at the shooting terminal that the cloud platform bore, consequently, before triggering the operation of shooing, need not the position that the terminal was shot in user's manual adjustment.
For example, the posture of the subject is recognized, and if the posture of the subject is a predetermined posture, the follow-up shooting mode is started. Continuously recognizing the posture of the shot object in the following shooting mode, and if the posture of the shot object is a preset shooting posture, executing shooting operation; the method is equivalent to remotely controlling the photographing by using the photographing gesture instead of touching a photographing button or key. Continuously recognizing the posture of the shot object in the following shooting mode, and if the posture of the shot object is a preset shooting posture, executing shooting operation; the method is equivalent to remotely controlling the shooting by utilizing the shooting gesture instead of touching a shooting button or a key. Taking a specific scene as an example, the user places the cradle head carrying the smart phone at a certain fixed position, and the user returns to the viewing area. In practical application, the user hardly ensures that the area that it got back to is exactly the region of finding a view, perhaps the user can change the region of finding a view, and this application is before shooing, even the user carries out certain extent's removal, because the cloud platform also can adjust automatically, make the camera shoot towards the user all the time, then the user can trigger the operation of shooing through the gesture of shooing, need not that the user gets back to the cloud platform and places the area and adjust the region of finding a view through contacting the button or the button on cell-phone or the cloud platform, the scene of shooing has greatly been richened.
It should be understood that the preset posture, the photographing posture and the photographing posture are different postures to trigger different operations by the different postures.
In some scenarios, since the tracking operation and the shooting operation need to be triggered separately, a problem of low operation efficiency may occur, and for this reason, in another example, the starting of the follow-up shooting mode includes: a photographing operation is performed and a tracking service for tracking the following object is started. That is, not only the tracking operation but also the photographing operation is triggered. Taking the shooting operation as an example of the image capturing operation, starting the follow-up shooting mode may refer to: and starting the camera shooting function and tracking the following object in the camera shooting process. In this embodiment, after making the preset gesture, the user can quickly control the shooting terminal to perform the track recording. Taking the photographing operation as the photographing operation, starting the follow-up photographing mode may refer to: and starting a tracking service for tracking the following object, and triggering one-time photographing operation or executing the photographing operation according to a preset frequency. In this embodiment, the user can quickly control the shooting terminal to perform tracking shooting after making the preset gesture.
In some scenarios, after the user makes a preset gesture, the user may not know whether the device side has successfully recognized and when to perform the corresponding operation, and for this reason, in one example, a delay mechanism and a feedback mechanism may be configured. As shown in fig. 2C, if the posture of the object is a preset posture, the starting of the follow-up shooting mode may include:
s241, when the posture of the shot object is a preset posture, counting down, and starting a following shooting mode when counting down is finished; and reminding is carried out in the countdown process and/or at the end of countdown, wherein the reminding carried out in the countdown process is different from the reminding carried out at the end of countdown.
The countdown time can be a fixed value, and can also be configured by a user, so that flexible configuration is realized. For example, the countdown may be 10s, or 5s, etc.
Regarding the feedback mechanism, the reminding can be performed in the countdown process, or the reminding can be performed at the end of the countdown, or even the reminding can be performed in both stages. For the purpose of distinction, the reminder made during the countdown is different from the reminder made at the end of the countdown. The manner of the reminder may be varied, including, but not limited to, displaying one or more of a reminder, an audible reminder, and a flashing reminder, for example. And displaying the reminding, wherein the reminding can be realized by displaying reminding information through a terminal screen. The reminder information may be text, images, video, etc. The sound reminding can be realized by playing a prompt tone. The alert tone may be a ring tone, music, voice, etc. The flash light reminding can be realized by flashing the flash light once or for multiple times.
In some application scenarios, the shooting terminal includes a front camera and a rear camera, and the screen is often located on the same terminal side as the front camera, or the screen is shot by using the front camera or the rear camera under different shooting requirements, for example, a closer picture is often shot by using the front camera, a farther picture is often shot by using the rear camera, and the like. The front camera shooting mode and the rear camera shooting mode are different in reminding mode.
For example, in a case where the terminal side where the front camera is located includes a screen and the terminal side where the rear camera is located does not include a screen, if it is recognized that the current image capturing mode is the front image capturing mode, the reminding mode may include displaying a reminder, and if it is recognized that the current image capturing mode is the rear image capturing mode, the reminding mode may not include displaying a reminder.
For example, the user can be reminded in a reciprocal number manner, and for example, the user can be reminded of successful identification in a text or image manner. As shown in fig. 2D, fig. 2D is a schematic diagram of an interface for displaying a reminder according to an exemplary embodiment of the present application. In the schematic diagram, the preset gesture may be a gesture in which five fingers are opened, and after the gesture is recognized, the user may be reminded of the success of gesture recognition through "recognized" on the screen, and a tracked object and the like may also be reminded in a manner of a character frame and the like.
In some scenes, the screen may not be seen in consideration of the situation that the distance is too far or the rear camera shoots, and therefore, the reminding mode can be a voice reminding mode. The alert means may be a flashing light alert for this reason, taking into account the possible fact that the ambient noise is too loud to mask the audible alert. It can be understood that the plurality of reminding modes can be combined to achieve reminding in a plurality of modes. For example, in the case where the posture of the subject is a preset posture, a countdown is entered, a first alert tone and a flashing light are played during the countdown, and a second alert tone is played at the end of the countdown, thereby enabling the user to determine whether or not the recognition is successful and when to start the follow-up photographing mode according to the prompt while distinguishing the countdown period from the countdown end according to different prompt manners. For the photographing and the image capturing, different second warning sounds may be used for distinguishing, for example, when the countdown is finished, the photographing is started by "clicking" indication. When the countdown is finished, start of image capturing is instructed by a "bite" or the like.
When the posture of the subject is a preset posture, the subject may be determined as a following subject so as to follow-up-shoot the following subject. The position information of the following object can be determined by the shot image, and correspondingly, before the position information of the following object, the method further comprises the following steps: position information of the following object is determined from the photographed image of the following object. The photographed image of the following object may be an image photographed by a photographing terminal. The position information of the following object may be determined by the position of the following object in the captured image.
And controlling the posture of the holder so that the following object is in the shooting range of the shooting terminal borne by the holder. For example, controlling the attitude of the pan/tilt head may include, but is not limited to: and adjusting the rotation angle and/or the rotation speed of the holder. Specifically, controlling the attitude of the pan/tilt head may include, but is not limited to: and adjusting one or more parameters of yaw angle, pitch angle, roll angle, yaw rotating speed, pitch rotating speed and roll rotating speed of the cradle head. For example, the rotation angle may be determined by the position of the following object in the captured image, and the rotation speed may be determined by the moving speed of the following object. It can be understood that how to control the posture of the pan/tilt head according to the position information of the following object, so that the following object can also be taken in the shooting range of the shooting terminal carried by the pan/tilt head in other manners in the related art, which are not described herein in detail.
In the process of continuously shooting the following object, there may be a situation that the following object is lost, and the reason for the loss includes various reasons, for example, the following object is shielded by a certain object, the following object quickly leaves a shooting range, the following object leaves all shooting ranges that can be shot by a shooting terminal, and the like, the loss of the following object may be intentional or accidental, and considering that an adverse effect caused by collecting more materials is smaller than an adverse effect caused by missing collecting materials, or a user desires to replace the following object, for this reason, in an embodiment, a new following object may be determined after the current following object disappears. For example, after controlling the attitude of the pan/tilt head so that the following object is within the shooting range of the shooting terminal carried by the pan/tilt head, the method further includes:
and when the following object is not in the shooting range of the shooting terminal or an instruction of replacing the following object is received, selecting another shot object from the shooting range as a new following object to carry out following shooting.
The instruction to replace the following object may be triggered by a user contact, a gesture for instructing switching of the object, or the like. When only one shot object exists in the shooting range, the shot object is directly used as a new following object, and when a plurality of shot objects exist in the shooting range, one of the shot objects can be selected as the new following object according to a preset strategy. For example, the object to be photographed in the middle area is selected as a new following object, and for example, an object having a control authority in the photographing range is selected as a new following object.
By taking one application scenario as an example, the following shooting of the object a can be realized after the gesture of the object a is recognized as the preset gesture; after the object A leaves the shooting range, if the object B exists in the shooting range, the object B can be subjected to follow-up shooting; after the object a leaves the shooting range, if a plurality of objects exist in the shooting range, the object in the middle area of the screen can be selected as a new follow-up object to perform follow-up shooting.
In the embodiment, the following object can be replaced by various means, more shooting requirements can be met, and user experience is improved.
In some application scenarios, before or during image capturing or photographing, it is further desirable to adjust the shooting parameters, and for this purpose, a gesture for instructing adjustment of the shooting parameters may be configured in advance, and accordingly, after the gesture of the object to be captured is recognized, the method further includes:
if the posture of the object is a preset parameter adjustment posture, performing shooting parameter adjustment operation corresponding to the parameter adjustment posture, where the shooting parameters include but are not limited to: one or more of a focal length, an aperture size, a shutter speed, sensitivity, a photometric mode, and the like. Different shooting parameters correspond to different parameter adjustment postures. It will be appreciated that the shooting parameters may also include the number of pictures taken, the exposure time at the time of shooting, and the like.
In the embodiment, the shooting parameters of the shooting terminal can be remotely controlled through the parameter adjusting posture, so that the condition that an operator needs to be close to the shooting terminal to adjust the shooting parameters is avoided.
In some application scenarios, there may be a need for ordinary shooting, and for this reason, in one embodiment, a shooting gesture for indicating shooting or a shooting gesture for indicating shooting may be configured in advance, and after the recognizing the gesture of the object to be shot, the method further includes: if the posture of the shot object is a preset shooting posture, executing shooting operation; and if the posture of the shot object is a preset shooting posture, executing shooting operation.
In the embodiment, different operations are indicated by different gestures, and the remote control shooting terminal can perform operations such as tracking shooting, fixed shooting and fixed shooting.
The various technical features in the above embodiments can be arbitrarily combined, so long as there is no conflict or contradiction between the combinations of the features, but the combination is limited by the space and is not described one by one, and therefore, any combination of the various technical features in the above embodiments also belongs to the scope disclosed in the present specification.
One of the combinations is exemplified below.
A photographing control method may include:
the posture of the subject is recognized.
If the posture of the shot object is a preset posture (can be called as a tracking posture), counting down, and when the counting down is finished, executing the shooting operation, starting a tracking service for tracking a following object, and determining that the shot object is the following object; and controlling the posture of the cradle head according to the position information of the following object, so that the following object is in the shooting range of a shooting terminal carried by the cradle head.
And if the posture of the object to be shot is a shooting posture, counting down, and executing the shooting operation when the counting down is finished.
The embodiment can solve the problem that the shooting angle of the shooting terminal cannot be adjusted again when a user does not hold the shooting terminal (the shooting terminal is away from the shooting terminal), and the purpose that the using scene of the handheld cloud deck is expanded to a non-handheld scene is achieved.
Taking the method as an example, the shooting software can identify the appointed gesture (such as a gesture) through the front/rear camera, and after the identification is successful, the shooting software automatically identifies the user and sends an instruction to the holder, so that the holder can be controlled by the user at a longer distance without contacting a mobile phone or holding the holder by hand.
