Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 invention.
Referring to fig. 1, fig. 1 is a flowchart of a shooting method according to an embodiment of the present invention, where the shooting method according to the embodiment of the present invention is applied to an electronic device, the electronic device includes a rotatable camera, and the camera is freely rotatable relative to a housing of the electronic device, as shown in fig. 1, the shooting method includes the following steps:
In this step, the photographic subject may be a distant photographic subject, and the first image may be a telephoto photographic image with respect to the photographic subject, that is, the first image may be an image that is perfectly aligned with the photographic subject.
The electronic equipment comprises a camera which can be used for long-focus shooting, and the camera can freely rotate relative to a shell of the electronic equipment. In the actual shooting process, the camera needs to be turned on first, and the camera for telephoto shooting is started, so that the lens magnification can be gradually enlarged and positioned near a target distant view (shooting object) in a shooting preview interface in a two-finger sliding mode, and an image collected by the camera can be as shown in fig. 2.
When a user holds the electronic device to shoot a long shot, the shot object moves out of the preview interface due to shaking of the user. Moreover, in the long-focus shooting process, due to the fact that the long-focus magnification is too high, the electronic device slightly shakes to reflect that huge movement can occur on the preview interface, and the shooting object part moves out of the preview interface.
The judgment basis that the spatial attitude information of the electronic device changes within the first duration can be judged based on the rotation range of the camera. Namely, the spatial position of the electronic equipment is changed, so that the shooting object partially moves out of the preview interface, and the shooting object is restored to the position in the preview interface before shaking by rotating the camera. If the variation range of the spatial position of the electronic equipment is large, the shooting object cannot be restored to the position of the shooting object in the preview interface before shaking only by rotating the camera, the current shooting is finished, and the user executes the alignment operation again.
If the spatial attitude information of the electronic equipment changes within the first time length, namely the camera can be rotated to restore the shooting object to the position of the shooting object in the preview interface before shaking, the angle change amount and the displacement change amount of the electronic equipment within the first time length are determined.
The angle variation of the electronic equipment can be obtained through calculation according to data acquired by a gyroscope of the electronic equipment; the displacement variation of the electronic equipment can be calculated through data collected by an accelerometer of the electronic equipment. The angle variation and the displacement variation of the electronic equipment in the first time length can be acquired through external auxiliary equipment, for example, the space position variation information of the electronic equipment is acquired through the external auxiliary equipment, and the acquired space position variation information is sent to the electronic equipment through communication modes such as Bluetooth and WiFi, so that the electronic equipment calculates the angle variation and the displacement variation based on the space position variation information.
And 102, determining the rotation angle of the camera based on the angle variation and the displacement variation.
In the step, as the camera is a part of the electronic equipment, the camera moves along with the electronic equipment under the condition that the spatial position of the electronic equipment is changed; therefore, the angle variation and the displacement variation of the electronic device are the angle variation and the displacement variation of the camera.
The rotation angle of the camera can be calculated through the angle variation and the displacement variation, so that after the camera rotates according to the rotation angle, the shooting object can be restored to the position of the shooting object in the preview interface before shaking (before the position of the electronic device is not changed).
In the process of calculating the rotation angle, a first rotation angle of the camera can be calculated firstly based on the angle variation; then, calculating a second rotation angle of the camera based on the displacement variation; because the three-dimensional coordinate system can be established under the condition that the spatial position of the electronic device changes, the first rotation angle and the second rotation angle are both spatial angles, namely vector angles (for example, an angle in an X direction, an angle in a Y direction, and an angle in a Z direction); and the rotation angle may be a vector sum of the first rotation angle and the second rotation angle.
In the process of calculating the second rotation angle, the second rotation angle can be calculated based on the relative distance change between the electronic equipment and the shooting object. For example, the relative distance between the electronic device and the shooting object may be acquired, and then the second rotation angle of the camera may be calculated based on the acquired displacement variation and based on the relative distance and the displacement variation.
And 103, controlling the camera to rotate according to the rotation angle, and outputting a second image acquired by the rotated camera.
In this step, the second image is an image obtained by rotating the camera, and the position of the photographic subject in the second image is the same as the position of the photographic subject in the first image, that is, after the camera is rotated by the rotation angle, the photographic subject can be returned to the position of the preview interface before shaking (before the position of the electronic device is not changed).
In the shooting process of the shooting object, the collected first image can be stored in a buffer queue all the time, so that the subsequently collected image frame can be compared with the first image, and the first image is the image frame completely aligned with the shooting object.
Therefore, under the condition that the electronic equipment shakes to cause the spatial posture of the electronic equipment to change, the shooting angle of the camera can be changed by rotating the camera, so that the shot object is restored to the position of the shot object in the preview interface before shaking, the preview interface of the shot object is restored, the spatial position of the electronic equipment is adjusted again to align the shot object, the shooting angle of the camera can be adjusted by controlling the rotation of the camera, the automatic alignment of the shot object is realized, the shooting operation of a user is effectively simplified, and the shooting effect of long-focus shooting can be improved.
The first time length may be a time length required for generating one frame of image, a time length required for shaking once by a user, or a time length customized by the user.
For example, when each frame of image is generated, the electronic device may calculate, based on angular acceleration data collected by a gyroscope of the electronic device and linear acceleration data collected by an accelerometer of the electronic device, and an elapsed time of the frame of image, an angle rotated by the electronic device and a displacement generated during a period of generating the frame of image, that is, an angle change amount and a displacement change amount of the electronic device in the first time period.
Whether the numerical values of the angle variation and the displacement variation are within a reasonable threshold range or not can be judged, if the numerical values exceed the reasonable threshold range, for example, if the camera cannot be rotated to restore the shooting object to the position of the shooting object in the preview interface before shaking, the camera is abandoned to be rotated, and the user is reminded to perform the alignment operation again; and if the distance is within a reasonable threshold value range, determining the rotation angle of the camera, and controlling the camera to rotate according to the rotation angle so as to restore the position of the shooting object in the preview interface before shaking.
Optionally, according to the rotation angle, controlling the camera to rotate, and outputting a second image acquired by the camera after rotation, includes: receiving a first input for the photographic subject in a photographic preview interface; responding to the first input, and controlling the camera to rotate according to the rotation angle; and outputting a second image collected by the camera after the camera rotates.
In this embodiment, the first input may be a click operation or a press operation on a photographic subject in the photographic preview interface, and is used to trigger the camera to rotate and output a second image acquired by the rotated camera, where a position of the photographic subject in the second image is the same as a position of the photographic subject in the first image. This can realize automatic shooting of the photographic subject.
In the process of determining the rotation angle, a three-dimensional coordinate system (an X direction, a Y direction, and a Z direction) can be established, the Z direction is a direction in which the camera faces the photographic subject, that is, a direction in which a connection line between the camera and the photographic subject is located, and a plane formed by the X direction and the Y direction is a plane perpendicular to the Z direction.
Wherein, based on the angular acceleration data collected by the gyroscope of the electronic device, the angle variation of the electronic device can be calculated, and the components of the calculated angle variation in the three directions of XYZ are expressed as (theta)x，θy，θz) Since the camera moves along with the electronic device, the camera needs to be controlled to rotate by a first rotation angle (-theta) in order to correct the angular deviation caused by the camera itselfx，-θy，-θz)。
Wherein, based on the linear acceleration data collected by the accelerometer of the electronic device, the displacement variation of the electronic device can be calculated, and the components of the calculated displacement variation in the three directions of XYZ are represented as (d)x，dy，dz) Because the camera is far away from the shooting object, the electronic deviceThe distance change in the Z direction caused by the spare space position change can be ignored, so the displacement change quantity of the camera can be represented by d (d ═ d)x，dy0), in order to correct the displacement variation of the camera caused by the spatial position variation of the electronic device, as shown in FIG. 3, an angle α required for the rotation of the camera is arctan (d/L), where L represents the distance from the camera to the shooting object, and the size of L can be obtained from a depth map obtained by the bronze drum double-shot algorithm or the depth learning algorithmx/L)，arctan(dy/L)，0)。
Vector addition is carried out on the first rotating angle and the second rotating angle, and then the rotating angle (-theta) of the camera can be obtainedx+arctan(dx/L)，-θy+arctan(dy/L)，-θz)。
Optionally, after the electronic device calculates the rotation angle of the camera, the camera may be controlled to rotate rapidly according to the rotation angle, so that the image area acquired by the camera is consistent with the image area acquired by the electronic device before shaking, and the acquired image is displayed on a preview interface. As shown in fig. 4, the rightmost image is an image acquired by the camera after the electronic device shakes; after the camera is controlled to rotate rapidly according to the rotation angle, the image acquisition visual angle is cut back to the original shooting area, namely as shown by the middle image; the captured image will be displayed on the preview interface as shown in the leftmost image.
After the camera is rotated and is switched back to the original shooting area, the operation of a user for the shooting button can be received, and shooting is carried out so as to obtain a long-range image of a shooting object.
Optionally, under the condition that the spatial posture information of the electronic device changes within a first time period, acquiring an angle variation and a displacement variation of the electronic device within the first time period includes: acquiring change information of the space attitude information of the electronic equipment within a first time period; and under the condition that the change information meets a preset condition, acquiring the angle change and the displacement change of the electronic equipment in the first time length.
In the embodiment, when the spatial attitude information of the electronic device changes, the shooting object part moves out of the preview interface; if the camera is rotated to restore the shooting object to the position of the shooting object in the preview interface before shaking, the change information meets the preset condition.
If the spatial position variation range of the electronic equipment is large, the shooting object cannot be restored to the position of the shooting object in the preview interface before shaking only by rotating the camera, the current shooting is finished, and the user executes the alignment operation again.
Therefore, the camera can be effectively prevented from being rotated inefficiently, and the shooting experience of a user is improved.
Optionally, the obtaining of the angle variation and the displacement variation of the electronic device in the first time period includes: acquiring a first position of the shooting object in a current preview image; determining an offset amount of the electronic device relative to the photographic subject based on the first position and a second position of the photographic subject in the first image; and calculating the angle variation and the displacement variation of the electronic equipment in the first time length based on the offset.
In this embodiment, the offset of the electronic device relative to the photographic object in the first time period can be calculated by the first position of the photographic object in the current preview image and the second position of the photographic object in the first image and based on the depth information of the photographic object, and further, the angle variation and the displacement variation of the electronic device in the first time period can be obtained. By adopting the mode, the accuracy of angle variation and displacement variation can be improved, the accuracy of the rotation angle is further improved, and the long-focus shooting effect of the shooting object is improved.
In the shooting method provided by the embodiment of the invention, in the process of acquiring a first image of a shooting object through the camera, and under the condition that the spatial attitude information of the electronic equipment is changed within a first time length, the angle change and the displacement change of the electronic equipment within the first time length are acquired; determining a rotation angle of the camera based on the angle variation and the displacement variation; controlling the camera to rotate according to the rotation angle, and outputting a second image acquired by the rotated camera; wherein the position of the photographic subject in the second image is the same as the position of the photographic subject in the first image. Therefore, the camera is rotated to change the shooting angle of the camera, so that the shooting object can be restored to the position of the shooting object in the preview interface before shaking, the spatial position of the electronic equipment is adjusted again relative to the shooting object, the shooting object can be aligned, the shooting angle of the camera can be adjusted by controlling the rotation of the camera, the automatic alignment of the shooting object is realized, the shooting operation of a user is effectively simplified, and the shooting effect of long-focus shooting can be improved.
