Description

Shooting control method and device and electronic equipment

Technical Field

The application belongs to the technical field of communication, and particularly relates to a shooting control method and device and electronic equipment.

Background

At present, in the prior art, when a user uses a mobile phone to shoot, the composition is performed by manually adjusting any angle such as a horizontal angle, a vertical angle, a rotation angle and the like of holding the mobile phone. When a user shoots a landscape with the horizon or shoots the appearance of a building group, the horizon is always required to be kept horizontal, and the vertical line is kept vertical, so that the occurrence of a picture which is askew and falls down is avoided, the shot object accords with the impression of human eyes, and the stable state is kept. Therefore, it is important that the mobile phone is placed horizontally for shooting and the picture is horizontally and vertically shot.

The user can also correct the composition angle through post-editing, for example, by using the horizontal axis, the central axis, and the center of the photo as the pivot through the picture editing software, and by stretching and deforming, the photo can be adjusted vertically, horizontally, and rotationally.

Therefore, the pictures taken by the mobile phone can only be horizontally and vertically arranged by elaborate composition arrangement at the early stage and correction means at the later stage. For an ordinary user, the shooting mode has high learning cost and use cost, namely, the user needs to spend a great deal of time and energy to search for a horizontal and vertical view angle, and excessive correction can cause pixel loss and blurring when the correction function is used at a later stage. In addition, for a mobile phone photographer to take a horizontal, flat and vertical picture, certain aesthetic bases, sharp observation power and certain shooting experience are required.

In addition, the imaging circle of the shift lens is larger than that of the traditional lens, and the lens can be deviated from the center by starting the translation function, so that the shot scene is changed. Such as a lens shift up or with a large imaging circle, the entire building can be photographed without tilting the camera, so that a non-distorted image can be photographed. However, the shift lens is very expensive and can only be used in digital single lens reflex.

Therefore, the existing method for shooting the photo or the video of the target object meeting the requirement of a certain direction has higher cost and cannot popularize the public users.

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 some, but not all, embodiments of the present application. 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 terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

Referring to fig. 1, an embodiment of the present invention provides a photographing control method, which may include:

step 101: and acquiring the rotation angle of the electronic equipment displaying the shooting picture in the first plane as a target rotation angle.

The first plane is a plane where a screen of the electronic device is located. For example, when the electronic device is rotated clockwise by X degrees in the first plane, the target rotation angle is-X degrees, and when the electronic device is rotated counterclockwise by X degrees in the first plane, the target rotation angle is + X degrees.

In addition, optionally, step 101 may be executed when it is detected that the shot picture belongs to a preset scene. For example, when it is detected that the captured picture belongs to a building scene, a street view, or a beach scene, the rotation angle of the electronic device displaying the captured picture in the first plane is acquired as the target rotation angle.

Step 102: and under the condition that at least one of the first straight line and the second straight line is detected in the shooting picture, controlling a camera of the electronic equipment to rotate in the first plane according to a third rotation angle of a third straight line, so that an included angle between the third straight line and the target direction is smaller than or equal to a first preset threshold value.

Here, the first rotation angle of the first straight line with respect to the first preset direction is: the first straight line rotates in the shooting picture according to a first target angle and then rotates by a rotation angle parallel to the first preset direction, and the first target angle is an included angle between the first straight line and the first preset direction;

the second rotation angle of the second straight line relative to the second preset direction is: and the second straight line rotates in the shooting picture according to a second target angle and then rotates by a rotation angle parallel to the second preset direction, and the second target angle is an included angle between the second straight line and the second preset direction.

In addition, when the rotation direction is counterclockwise, the sign of the rotation angle is "positive"; when the rotation angle is clockwise, the sign of the rotation angle is "negative". Therefore, the target rotation angle, the first rotation angle, the second rotation angle, and the third rotation angle have a "positive" sign when the rotation direction is counterclockwise, and have a "negative" sign when the rotation direction is clockwise.

Further, optionally, the first preset threshold may be 0 °, and the second preset threshold may be 0 °.

As can be seen from the above description, in the embodiment of the present application, if only the first straight line is detected in the shooting picture, the camera is controlled to rotate in the first plane according to the first rotation angle of the first straight line, so that the included angle between the first straight line and the first preset direction is smaller than or equal to the first preset threshold, that is, the camera is controlled to rotate in the first plane, so that the first straight line is parallel to the first preset direction as much as possible.

If only the second straight line is detected in the shot picture, the camera is controlled to rotate in the first plane according to the second rotation angle of the second straight line, so that the included angle between the second straight line and the second preset direction is smaller than or equal to the first preset threshold value, namely, the camera is controlled to rotate in the first plane, so that the second straight line is parallel to the second preset direction as far as possible.

If the first straight line and the second straight line are detected in the shooting picture at the same time, selecting one straight line from the first straight line and the second straight line, and controlling the camera to rotate in the first plane according to the rotation angle of the selected straight line so that the included angle between the selected straight line and the direction corresponding to the selected straight line is smaller than or equal to a first preset threshold value.

In addition, if the included angle between the third straight line and the target direction is smaller than or equal to the first preset threshold, for example, the included angle is 0, then the rotation is not performed.

That is, when the third straight line is the first straight line, if the absolute value of the first rotation angle of the first straight line relative to the first preset direction is smaller than or equal to the first preset threshold, for example, the absolute value of the first rotation angle is 0, then the third straight line does not rotate; when the third straight line is the second straight line, if the absolute value of the second rotation angle of the second straight line relative to the second preset direction is smaller than or equal to the first preset threshold, for example, the absolute value of the second rotation angle is 0, the second straight line does not rotate.

The absolute value of the difference between the first rotation angle and the target rotation angle is smaller than or equal to a second preset threshold value, and the signs of the difference are opposite, which indicates that the deflection of the first straight line in the shooting picture relative to the first preset direction is caused by the rotation of the electronic equipment in the first plane; similarly, the absolute value of the difference between the second rotation angle and the target rotation angle is smaller than or equal to a second preset threshold and has opposite signs, which indicates that the deflection of the second straight line in the shooting picture relative to the second preset direction is caused by the rotation of the electronic device in the first plane. Therefore, in the embodiment of the application, when at least one of the first straight line and the second straight line is detected in the captured image, the camera of the electronic device may be controlled to rotate in the first plane to compensate for the rotation angle of the electronic device in the first plane, so that the first straight line in the captured image is parallel to the first preset direction as much as possible, or the second straight line in the captured image is parallel to the second preset direction as much as possible.

Therefore, when a photo or a video with a target object meeting a certain direction requirement is shot, whether the rotation angle of the electronic device can automatically detect whether the deviation of the shot object in the shot picture from the expected direction occurs or not (namely, whether the deviation of the shot object in the shot picture from the expected direction is caused by the rotation of the electronic device) can be detected, so that the compensation can be performed through the rotation of the camera, the user does not need to manually rotate the electronic device or perform the post correction processing, and the user does not need to have professional shooting experience.

Optionally, when the first straight line and the second straight line are detected in the shooting picture, the third straight line is one of the first straight line and the second straight line, which has the longest length.

Wherein, the direction of the longest straight line in first straight line and the second straight line can be more accurate the direction of representing the target object orientation of being shot, consequently selects the longest straight line in first straight line and the second straight line to according to the rotation angle of this straight line of electing, the control camera rotates, compensation electronic equipment's that can be more accurate rotation, and then further promote the shooting effect.

In addition, the first straight line includes a plurality of straight lines having an absolute value of a difference between a magnitude of the rotation angle with respect to the first preset direction and a magnitude of the target rotation angle smaller than or equal to a second preset threshold value and having opposite signs, and the second straight line includes a plurality of straight lines having an absolute value of a difference between a magnitude of the rotation angle with respect to the second preset direction and a magnitude of the target rotation angle smaller than or equal to the second preset threshold value and having opposite signs.

Optionally, the process of detecting the first straight line in the captured picture includes:

detecting a straight line in the shooting picture as a candidate straight line;

and selecting a straight line with an included angle with the first preset direction smaller than a third preset threshold value from the candidate straight lines to serve as the first straight line.

In the embodiment of the application, a hough transform method may be adopted to detect a straight line in a shot picture. The Hough Transform (Hough Transform) is a method for detecting simple geometric shapes such as straight lines and circles in image processing. The prototype of the hough transform is as follows:

void HoughLines(InputArray image,OutputArray lines,double rho,double theta,int threshold,double srn＝0,double stn＝0)；

the input of the Hough transform is a binary contour image which is often a result image obtained by edge detection; the output is an array containing a plurality of Vec2f points, each element in the array being a binary floating point data pair < rou, theta >, rou representing the distance of the line from the origin of coordinates, theta representing the angle. Since the hough transform is actually an exhaustive algorithm, rho represents the step size of the distance and theta represents the step size of the angle.

Therefore, when the picture of the captured picture in step 101 is input using the prototype of the hough transform, a plurality of straight lines in the captured picture can be output.

In addition, according to the subject and the shooting habit in shooting, a type of photo which intentionally uses oblique lines to break the smoothness of the picture, such as diagonal line composition and vanishing line composition, needs to be removed. Namely, the embodiment of the application is only used for meeting the situation that the shot object deviates from the expected direction in the shot picture due to the fact that the common user is not stable in the handheld electronic equipment and does not have aesthetic awareness of shooting. Therefore, in the embodiment of the present application, after the straight lines in the captured picture are detected, straight lines with an inclination angle meeting a certain requirement (for example, an included angle between the straight lines and the first preset direction is required to be less than 10 degrees, that is, a rotation angle relative to the first preset direction is required to be within a range of negative 10 degrees and positive 10 degrees) need to be selected from the straight lines, so that the rotation of the electronic device is prevented from being compensated by using the camera in a scene of diagonal composition or vanishing line composition, that is, false capturing of the scene of diagonal composition and vanishing line composition is avoided.

Optionally, before selecting a straight line, of which an included angle with the first preset direction is smaller than a third preset threshold, from the candidate straight lines, to serve as the first straight line, the method further includes:

and eliminating straight lines with the length smaller than a first preset length from the candidate straight lines.

Therefore, in the embodiment of the application, after the candidate straight lines in the shooting picture are detected, the straight lines with the length smaller than the first preset length can be removed, so that the straight lines with the included angle with the first preset direction smaller than the third preset threshold value are selected from the remaining straight lines to be used as the first straight lines. That is, the candidate straight line whose length is greater than or equal to the first preset length and whose included angle with the first preset direction is smaller than the third preset threshold may be used as the first straight line.

The direction of the candidate straight line with the longer length can more accurately represent the direction of the shot target object, therefore, the candidate straight line with the length larger than or equal to the first preset length and the included angle with the first preset direction smaller than the third preset threshold value is selected as the first straight line, and when the camera is controlled to rotate according to the first rotating angle of the first straight line, the rotation of the electronic equipment can be more accurately compensated, and the shooting effect is further improved.

In addition, OpenCV provides a function HoughLinesP. OpenCV is a cross-platform computer vision and machine learning software library based on berkeley software suite (BSD) licensing. The HoughLinesP function is as follows:

void HoughLinesP(InputArray image,OutputArray lines,double rho,double theta,int threshold,double minLineLength＝0,double maxLineGap＝0)；

the output of HoughLinesP is a Vector of Vec4 i. That is, each element of the Vector represents a straight line and is composed of a 4-element floating point array, one set of the first two points and one set of the last two points represent the starting point and the ending point of the straight line in the image. From this, it can be seen that the length of the candidate straight line detected in the above-described captured image can be calculated by using the HoughLinesP function.

Optionally, the process of detecting the second straight line in the shot picture includes:

detecting a straight line in the shooting picture as a candidate straight line;

and selecting a straight line with an included angle with the second preset direction smaller than a third preset threshold value from the candidate straight lines to serve as the second straight line.

Optionally, before selecting a straight line, of which an included angle with the second preset direction is smaller than a third preset threshold, from the candidate straight lines to serve as the second straight line, the method further includes:

Therefore, the process of detecting the second straight line in the shot picture is similar to the process of detecting the first straight line in the shot picture, and is not described in detail here.

Optionally, a pan-tilt gyroscope is arranged inside the electronic device, and the pan-tilt gyroscope is fixedly connected with the camera;

the controlling the camera of the electronic device to rotate in the first plane according to the third rotation angle of the third straight line includes:

and controlling the holder gyroscope to rotate in the first plane according to the third rotation angle.

And controlling the holder gyroscope to rotate according to a third rotation angle in the first plane, namely controlling the holder gyroscope to rotate according to the third rotation angle and the rotation direction of the third rotation angle in the first plane.

Therefore, in the embodiment of the application, the inside cloud platform gyroscope that is provided with of electronic equipment, and this cloud platform gyroscope and camera fixed connection, consequently, the rotation angle that cloud platform gyroscope can real-time detection electronic equipment, and cloud platform gyroscope still can drive the camera and rotate together to change and shoot the angle. Therefore, in the embodiment of the application, the camera can be driven to rotate according to the third rotation angle in the first plane through the holder gyroscope.

Optionally, before controlling the camera of the electronic device to rotate in the first plane according to the third rotation angle of the third straight line, the method further includes:

displaying the third straight line in the shooting picture;

executing a preset prompting operation, wherein the preset prompting operation is used for instructing a user to execute a preset operation on the third straight line displayed in the shooting picture;

and under the condition of receiving the preset operation, controlling the camera to rotate in the first plane according to a third rotation angle of the third straight line.

Therefore, in the embodiment of the application, after the third straight line in the shooting picture is determined, the third straight line may be displayed in the shooting picture, and the user is prompted to perform a preset operation on the displayed third straight line so as to trigger the step of "controlling the camera of the electronic device to rotate in the first plane according to the third rotation angle of the third straight line". For example, after the third straight line is displayed, the user may be prompted to click on the third straight line, so as to trigger the change of the shooting angle of the camera, so that the third straight line is parallel to the target direction as much as possible.

Optionally, before the step of acquiring the rotation angle of the electronic device displaying the shooting picture in the first plane, the method further includes:

receiving an adjustment operation on a shooting angle;

and responding to the adjustment operation, and controlling the camera to rotate according to a fourth rotation angle indicated by the adjustment operation.

Therefore, in the embodiment of the present application, the shooting angle can be changed through the operation of the user before the step 101, so that the shooting at a specific angle is realized, more shooting modes are provided for the user, and further more shooting requirements can be met.

Optionally, the controlling the camera to rotate according to the fourth rotation angle indicated by the adjustment operation includes:

controlling the camera to rotate in a target plane according to the fourth rotation angle;

wherein the target plane is the first plane or a second plane perpendicular to the first plane;

when the target plane is the first plane, after the camera is controlled to rotate in the target plane according to the fourth rotation angle, the method further includes:

and respectively rotating the first preset direction and the second preset direction in the shooting picture according to the fourth rotation angle.

Therefore, the shooting at a specific angle that can be realized in the embodiment of the present application includes two cases of the camera rotating in the first plane and the camera rotating in the second plane, where the camera rotating in the first plane corresponds to: shooting in an inclined mode; the camera rotates in the second plane, and then corresponds to: and carrying out elevation angle or depression angle shooting.

When the camera rotates in the first plane, namely when the camera is obliquely shot, after the camera is controlled to rotate in the first plane according to the fourth rotation angle, the first preset direction and the second preset direction can be synchronously adjusted, so that the adjusted first preset direction and the adjusted second preset direction are matched with the changed shooting angle, and a user can shoot a picture or a video at a specific angle without rotating the electronic equipment.

In addition, when the camera rotates in the second plane, that is, when the camera performs the elevation angle or depression angle shooting, after the camera is controlled to rotate in the first plane according to the fourth rotation angle, the first preset direction and the second preset direction do not need to be synchronously adjusted, that is, the first preset direction and the second preset direction are kept unchanged.

Specifically, the following target scenes are exemplified as an application scene in which the shooting angle, the first preset direction and the second preset direction are rotated according to the fourth rotation angle:

for example, the first preset direction is a horizontal direction, the second preset direction is a vertical direction, and a pencil needs to be photographed in a certain photographing scene, but the pencil is placed at an angle of 45 degrees with the horizontal direction, at this time, a user may change the first preset direction to rotate the pencil counterclockwise by 45 degrees in a photographing picture, change the second preset direction to rotate the pencil counterclockwise by 45 degrees in the photographing picture, and control the camera to rotate counterclockwise by 45 degrees in the first plane to change a photographing angle of the camera, and then execute the step 101 and the step 102, so that a picture or a video of the pencil parallel to the horizontal direction in the photographing picture can be photographed without rotating the electronic device.

Optionally, after controlling the camera to rotate in the target plane according to the fourth rotation angle, the method further includes:

when the electronic equipment is detected to rotate and return in the direction opposite to the rotating direction of the fourth rotating angle in the target plane, controlling the camera to rotate in the target plane according to the magnitude of the fourth rotating angle and the direction opposite to the rotating direction of the fourth rotating angle;

wherein, when the target plane is the first plane, the method further comprises:

and under the condition that the electronic equipment is detected to rotate and recover along the direction opposite to the rotation direction of the fourth rotation angle in the target plane, respectively controlling the first preset direction and the second preset direction, and rotating according to the size of the fourth rotation angle and the direction opposite to the rotation direction of the fourth rotation angle in the shooting picture.

For example, after the shooting angle of the camera is fixed to be 45 degrees in the first plane in the counterclockwise direction in the horizontal direction, if the user rotates the handheld electronic device in the first plane in the counterclockwise direction (i.e., in the clockwise direction) at the first moment and then resumes the rotation in the video shooting process, the camera is controlled to rotate 45 degrees in the first plane in the clockwise direction from the current angle, the first preset direction is controlled to resume the horizontal direction, and the second preset direction is controlled to resume the vertical direction, so as to resume the shooting at the normal angle.

Or, in the process of controlling the camera to perform elevation shooting in other scenes, if the user rotates the handheld electronic device in the second plane in the opposite direction of the elevation at the first moment and then restores the angle, the camera is controlled to perform flat angle shooting, that is, shooting at a normal angle is restored.

Therefore, in the embodiment of the application, in the process of shooting at the specific angle, the user can also restore to the normal shooting angle by rotating the electronic equipment, and the operation process is simple and convenient.

Optionally, after the camera is controlled to rotate in the target plane according to the magnitude of the fourth rotation angle and a direction opposite to the rotation direction of the fourth rotation angle, the method further includes:

under the condition that the electronic equipment is detected to rotate and recover along the rotation direction of the fourth rotation angle in the target plane, controlling the camera to rotate according to the fourth rotation angle in the target plane;

and under the condition that the electronic equipment is detected to rotate and recover along the rotation direction of the fourth rotation angle in the target plane, respectively controlling the first preset direction and the second preset direction, and rotating according to the fourth rotation angle in the shooting picture.

For example, after the first time in the target scene, the user rotates the handheld electronic device in the counterclockwise direction in the first plane at the second time and then resumes the rotation, the camera is controlled to rotate counterclockwise by 45 degrees in the first plane from the current angle, the first preset direction is controlled to resume the direction after rotating counterclockwise by 45 degrees in the horizontal direction, and the second preset direction is controlled to resume the direction after rotating counterclockwise by 45 degrees in the vertical direction, so as to resume the shooting at the specific angle.

Or, in the process of controlling the camera to shoot at the elevation angle in other scenes, if the user rotates the handheld electronic device in the second plane in the opposite direction of the elevation angle at the first moment and then restores, the camera is controlled to shoot at the flat angle; and then, if the user rotates the handheld electronic equipment in the second plane to the direction of the elevation angle at the second moment and recovers, controlling the camera to shoot the elevation angle again.

Therefore, in the embodiment of the application, after the shooting at the specific angle is performed, if the shooting is recovered to the normal shooting, the electronic device can be further rotated to enter the specific angle again for shooting, and the operation process is simple and convenient.

Optionally, before receiving the operation of adjusting the shooting angle, the method further includes:

displaying a preset indication mark in the shooting picture;

the receiving of the adjustment operation of the shooting angle comprises:

and receiving a dragging operation of the preset indication mark, wherein a rotation angle of the dragging operation is the fourth rotation angle.

Therefore, the preset indication mark can be displayed in the shooting picture, so that a user can modify the shooting angle by dragging the preset indication mark, wherein the rotating angle of the dragged preset indication mark is the fourth rotating angle which needs to be rotated to control the camera to shoot at a specific angle.

In addition, the specific camera rotates in the first plane or the second plane according to the fourth rotation angle, and the camera may default to rotate in one of the first plane or the second plane; the user can also select the first plane and the second plane by himself, for example, options of the first plane and the second plane are provided in the photographing setting interface, so that the user can select the first plane and the second plane by himself.

Optionally, the receiving an operation of adjusting a shooting angle includes:

receiving an operation of inputting the fourth rotation angle in the electronic device as the adjustment operation.

Therefore, the user can input a specific rotation angle in the electronic equipment to control the camera to shoot at a specific angle. Here, the rotation angle input by the user includes an angle size and a rotation direction.

As described above, the specific implementation of the shooting control method according to the embodiment of the present application can be as shown in fig. 2, which is described in detail below.

Step 201: using AI scene recognition technology, it is recognized whether the current shooting scene is a building, a street view, or a beach, if yes, step 202 is executed.

Step 202: straight lines in the captured picture are detected as candidate straight lines.

Step 203: selecting a straight line Lx and a straight line Ly from the candidate straight lines, and recording a first rotation angle of the Lx relative to the horizontal direction and a second rotation angle of the Ly relative to the vertical direction;

among the candidate straight lines, a straight line which forms an included angle with the horizontal direction of less than 10 degrees and has a length of more than or equal to one half of the length of the X axis in the shooting picture is marked as Lx; the straight line which has an included angle with the vertical direction smaller than 10 degrees and has the length larger than or equal to one half of the length of the Y axis in the shooting picture is marked as Ly;

in addition, the range of the first rotation angle of Lx with respect to the horizontal direction, and the range of the second rotation angle of Ly with respect to the vertical direction may be as shown in fig. 3;

step 204: a holder gyroscope arranged in the electronic equipment judges the rotation angle of the electronic equipment in a first plane where a screen of the electronic equipment is located, and the rotation angle is recorded as a target rotation angle;

step 205: comparing the target rotation angle with the first rotation angle and the second rotation angle, selecting L1, and displaying L1 as a yellow straight line in the shooting picture, wherein the yellow straight line is named L2;

selecting a rotation angle with the same size and opposite sign as the target rotation angle from the first rotation angle and the second rotation angle, and if the rotation angle and the second rotation angle are both the same size and opposite sign as the target rotation angle, selecting one of Lx and Ly with longer length as L1; if one of the first rotation angle and the second rotation angle is equal to the target rotation angle in magnitude and opposite in sign, the straight line to which the rotation angle belongs is L1;

here, if the angle of L1 is zero, the flow ends;

for example, if the rotation angle of the electronic device with respect to the horizontal direction on the photographing screen Lx shown in fig. 4 is-3 °, the target rotation angle of the electronic device is +3 °, the Lx is named L1, and L2 is displayed on the photographing screen;

step 206: displaying a prompt on the shooting picture to prompt the user to click the straight line L2;

step 207: after the user clicks the L2, the pan-tilt gyroscope rotates, wherein the angle at which the user can see that the image is taken changes in the image taken, i.e., the straight line L2 rotates to 0 °. Wherein, the change of the shooting picture before and after the rotation of the tripod head gyroscope is shown in fig. 5.

step H1: dragging the crossed straight line displayed in the shooting picture by a user to rotate, and displaying the real-time angle in the picture; the user can continue to rotate to a required angle or directly input the required angle into the electronic equipment, the shooting angle of the picture is fixed (for example, inclined shooting, elevation shooting or depression shooting) according to the requirement of the user, and the shooting angle of the picture can be anchored through automatic adjustment of a tripod head gyroscope and recorded as special angle shooting;

if the step H1 is present before the step 203, after the step 207, the following step H2 may be further included:

step H2: in the video shooting process, if the user holds the electronic equipment to rotate in the opposite direction of a specific angle at the first moment and then recovers, the normal shooting is recovered; after the normal shooting is resumed, if the user rotates the handheld electronic device in the direction of the specific angle at the second moment and then resumes, the easy-specific-angle shooting is continued.

Therefore, the shooting control method of the embodiment of the application can realize the shooting method for assisting the user in quickly shooting the horizontal and vertical picture, and has the advantages that the angle calculation of the straight line recognition of the image algorithm and the rotation angle detection of the electronic equipment by the pan-tilt gyroscope are combined, wherein the correlation is that when the angle of a certain straight line Lx or Ly is recognized to be capable of offsetting with the rotation angle of the electronic equipment, a horizontal or vertical picture of a certain line can be shot through the rotation of the electronic equipment, and therefore the non-horizontal or non-vertical line in the shot picture is rotated to be horizontal, vertical or to a specific inclination angle through the rotation of the pan-tilt gyroscope.
