Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In one embodiment, as shown in fig. 1, a method for controlling a shooting device is provided, and the embodiment is described as being applied to a shooting system integrated with a control module, and it is understood that the method can also be applied to a control platform, and the control platform is connected with the shooting device and controls the shooting device to carry out shooting operation. In this embodiment, the method includes the steps of:
and 102, responding to touch operation, and acquiring a first touch coordinate and a second touch coordinate.
Specifically, the shooting system listens for a touch operation in real time, where the touch operation refers to an operation of performing touch on a touch screen corresponding to the shooting system, and the touch screen may specifically be a display screen, a virtual screen, or the like, and this embodiment is not specifically limited here. For example, the touch operation may specifically refer to a single finger of the user touching the corresponding touch screen. For another example, the touch operation may specifically refer to a user touching the corresponding touch screen with two fingers. The first touch coordinate is a coordinate acquired when the touch operation is intercepted. The second touch coordinate is determined after the user performs the touch operation for the first time and slides on the corresponding touch screen. For example, when a user clicks any screen position on the corresponding touch screen with a finger and slides a distance on the corresponding touch screen with the finger, the first touch coordinate represents the screen position clicked by the user, and the second touch coordinate represents the screen position where the finger stays after the user slides a distance from the screen position clicked by the user.
Further, when the touch operation is intercepted, the shooting system acquires a first touch coordinate of the user clicking the corresponding touch screen at the moment, continues intercepting the sliding of the user finger on the corresponding touch screen, and acquires a second touch coordinate of the finger staying at the moment when the finger sliding is suspended. For example, when the user continues to listen to the sliding of the finger on the corresponding touch screen, the shooting system may obtain the dwell time of the finger of the user at each position on the corresponding touch screen, and when the dwell time reaches a preset dwell time threshold, the shooting system may position the corresponding dwell position as the second touch coordinate, where the preset dwell time threshold may be set as needed.
And 104, when the control mode is zoom according to the first touch coordinate and the second touch coordinate, determining the coordinate of the center point of the target display picture according to the first touch coordinate.
Zooming refers to making a shot object look closer or farther, zooming includes both zooming in and zooming out, zooming in can make the shot object view closer, and zooming out can capture a wider space. The target display picture is a picture to be displayed on the corresponding touch screen, the target display picture corresponds to a picture collected and output by the shooting system, and the coordinate of the center point of the target display picture is the coordinate of the center point of the target display picture.
Specifically, after the first touch coordinate and the second touch coordinate are obtained, the shooting system determines the corresponding control mode according to the number of the coordinate points in the first touch coordinate and the second touch coordinate, and when the number of the coordinate points in the first touch coordinate and the number of the coordinate points in the second touch coordinate are both two, that is, when the user operates the corresponding touch screen by using two fingers, the shooting system determines that the control mode is zooming. After the control mode is determined to be zooming, the shooting system needs to determine the center point coordinate of the target display picture, which corresponds to the center point of the area that the user wants to zoom (zoom in or zoom out), according to the first touch coordinate.
And 106, moving the current display picture until the center point corresponding to the current display picture reaches the center point coordinate of the target display picture, and zooming according to the first touch coordinate and the second touch coordinate.
Specifically, a current display picture is displayed on a touch screen corresponding to the shooting system, after a target display picture central point coordinate is determined, the shooting system acquires a central point corresponding to the current display picture, and determines how to rotate the shooting system if the central point corresponding to the current display picture is moved to the target display picture central point coordinate according to the target display picture central point coordinate and the central point corresponding to the current display picture, and the central point corresponding to the current display picture is moved to the target display picture central point coordinate by performing corresponding rotation.
Specifically, the shooting system determines whether the specific zooming mode is zooming-in or zooming-out according to the coordinate point in the first touch coordinate and the coordinate point in the second touch coordinate, further determines a zooming multiple according to the coordinate point after determining the specific zooming mode, and zooms according to the specific zooming mode and the zooming multiple. When the zoom factor is determined according to the coordinate point, the shooting system determines the coordinate distance according to the coordinate point, and determines the zoom factor according to the corresponding relationship between the preset coordinate distance and the unit zoom factor, wherein the corresponding relationship between the coordinate distance and the unit zoom factor can be set automatically as required, for example, the corresponding relationship between the coordinate distance and the unit zoom factor can be specifically amplified by 1 time when every 20 pixels are added.
And step 108, acquiring the zoomed acquisition picture, and acquiring a real-time display picture according to the zoomed acquisition picture.
The real-time display frame refers to a display frame displayed on the corresponding touch screen in real time.
Specifically, after zooming, the shooting system obtains a zoomed acquisition image, and outputs the zoomed acquisition image to the corresponding touch screen, so as to display a real-time display image on the corresponding touch screen.
The method for controlling the shooting equipment acquires the first touch coordinate and the second touch coordinate by responding to the touch operation, determines the coordinate of the central point of the target display picture according to the first touch coordinate when the control mode is zooming according to the first touch coordinate and the second touch coordinate, moves the current display picture until the central point corresponding to the current display picture reaches the coordinate of the central point of the target display picture, zooms according to the first touch coordinate and the second touch coordinate, acquires the zoomed acquisition picture, acquires the real-time display picture according to the zoomed acquisition picture, and realizes the zooming control by touching and sliding the first touch coordinate and the second touch coordinate obtained by the real-time display picture in the whole process, thereby solving the problem of inconvenient control operation by using a mouse in the prior art, in addition, no additional hardware device is needed, the cost can be saved.
In one embodiment, further comprising:
when the number of the coordinate points in the first touch coordinate and the number of the coordinate points in the second touch coordinate are both two, determining that the control mode is zooming;
and when the number of the coordinate points in the first touch coordinate and the number of the coordinate points in the second touch coordinate are both less than two, determining that the control mode is rotation.
Specifically, according to the operation habit, the correspondence between the touch screen mode and the control mode is preset, and when the touch screen mode is one-finger touch, the control mode can be regarded as rotation, and when the touch screen mode is two-finger touch, the control mode can be regarded as zooming. The shooting system can determine whether the touch screen mode of the user is single-finger touch or double-finger touch through the number of coordinate points in the first touch coordinate and the second touch coordinate, when the number of the coordinate points in the first touch coordinate and the second touch coordinate is less than two, the touch screen mode is represented as single-finger touch, the shooting system can determine that the control mode is rotation, when the number of the coordinate points in the first touch coordinate and the number of the coordinate points in the second touch coordinate are two, the touch screen mode is represented as double-finger touch, and the shooting system can determine that the control mode is zooming.
In this embodiment, the determination of the control mode can be realized according to the number of coordinate points in the first touch coordinate and the number of coordinate points in the second touch coordinate.
In one embodiment, when the number of coordinate points in the first touch coordinate and the number of coordinate points in the second touch coordinate are both less than two, after determining that the control manner is rotation, the method further includes:
rotating according to the first touch coordinate and the second touch coordinate;
and acquiring a rotated acquisition picture, and acquiring a real-time display picture according to the rotated acquisition picture.
Specifically, after the control mode is determined to be rotation, the shooting system can determine whether the specific rotation direction is leftward rotation, rightward rotation, upward rotation or downward rotation according to the first touch coordinate and the coordinate point in the second touch coordinate, rotate according to the specific rotation mode, acquire a rotated rotation acquisition picture after the rotation is completed, and obtain a real-time display picture according to the rotation acquisition picture.
Further, when multiple rotations need to be performed, a user can continuously slide on the corresponding touch screen by using a single finger, when the shooting system monitors a touch operation, new first touch coordinates and second touch coordinates can be obtained, and a new specific rotation direction is determined again according to the new first touch coordinates and the new second touch coordinates. When the shooting system rotates for many times, the speed of the shooting system rotating is in positive correlation with the speed of the finger sliding on the corresponding touch screen, the faster the finger slides on the corresponding touch screen, the faster the shooting system rotates, and the slower the finger slides on the corresponding touch screen, the slower the shooting system rotates. In this embodiment, the single rotation angle at which the photographing system rotates can be set by itself as required.
In this embodiment, by rotating according to the first touch coordinate and the second touch coordinate, a rotated rotation acquisition picture can be obtained after the rotation is completed, and a real-time display picture can be obtained according to the rotation acquisition picture.
In one embodiment, rotating according to the first touch coordinate and the second touch coordinate includes:
calculating a coordinate point difference value between coordinate points corresponding to the same coordinate axis in the first touch coordinate and the second touch coordinate;
and comparing coordinate point difference values corresponding to different coordinate axes, and rotating according to a comparison result.
Specifically, according to a preset coordinate system and a coordinate origin, the shooting system can determine coordinate information of a coordinate point in a first touch coordinate and coordinate information of a coordinate point in a second touch coordinate, and further can determine a specific rotation direction by calculating a coordinate point difference between coordinate points corresponding to the same coordinate axis in the first touch coordinate and the second touch coordinate and comparing the coordinate point difference corresponding to different coordinate points, and rotate according to the specific rotation direction.
For example, the preset coordinate system may be an XOY coordinate system, the origin of coordinates may be any point on the touch screen, the coordinate information of the coordinate point in the first touch coordinate may be (X1, Y1), the coordinate information of the coordinate point in the second touch coordinate may be (X2, Y2), and the photographing system may determine a specific rotation direction by calculating coordinate point differences (i.e., X1-X2, Y1-Y2) between coordinate points (X1 and X2, Y1 and Y2) corresponding to the same coordinate axis, and comparing the coordinate point differences (i.e., X1-X2 and Y1-Y2) corresponding to different coordinate axes, so as to rotate according to the specific rotation direction. Note that, for the convenience of calculation, an absolute value may be calculated here when the coordinate point difference is calculated.
Further, the specific rotation direction in this embodiment is exemplified to determine the left rotation direction and the right rotation direction with respect to the corresponding touch screen, and the end of the corresponding touch screen close to the ground is taken as the downward rotation direction, and the end of the corresponding touch screen far from the ground is taken as the upward rotation direction. When the absolute values of X1-X2 are less than the absolute values of Y1-Y2 and the absolute values of Y1-Y2 are greater than the trigger rotation threshold, the specific rotation direction is determined to be upward rotation. When the absolute value of X1-X2 is less than the absolute value of Y1-Y2 and the absolute value of Y2-Y1 is greater than the trigger rotation threshold, the specific rotation direction is determined to be downward rotation. And when the absolute value of X1-X2 is greater than the absolute value of Y1-Y2 and X1-X2 is greater than a trigger rotation threshold value, determining that the specific rotation direction is a left rotation, and when the absolute value of X1-X2 is greater than the absolute value of Y1-Y2 and X2-X1 is greater than a trigger rotation threshold value, determining that the specific rotation direction is a right rotation, wherein the trigger rotation threshold value is a trigger condition for generating a rotation instruction and can be set by self as required.
In this embodiment, by calculating a coordinate point difference between coordinate points corresponding to the same coordinate axis in the first touch coordinate and the second touch coordinate, coordinate point differences corresponding to different coordinate axes are compared, and rotation can be performed according to the comparison result.
In one embodiment, determining the coordinates of the center point of the target display screen according to the first touch coordinates comprises:
and calculating a coordinate center point between different coordinate points in the first touch coordinate to obtain a coordinate of the center point of the target display picture.
Specifically, after the control mode is determined to be zoom, the shooting system needs to adjust a center point of a display screen corresponding to the touch screen, and determine a new center point of the display screen, that is, a target display screen center point, at this time, the first touch coordinate includes two coordinate points (X1, Y1) and (X2, Y2), and the terminal calculates a coordinate center point coordinate between the two coordinate points, and uses the coordinate center point coordinate as the target display screen center point coordinate. For example, the coordinate center point coordinate (X, Y) is calculated by X ═ X1+ X2)/2 and Y ═ Y1+ Y2)/2.
In this embodiment, the coordinate of the center point of the target display screen can be obtained according to the coordinate center point by calculating the coordinate center point between different coordinate points in the first touch coordinate.
In one embodiment, moving the current display until the center point corresponding to the current display reaches the center point coordinates of the target display comprises:
acquiring a central point corresponding to a current display picture and a corresponding relation between picture pixels and a rotation angle;
determining an offset pixel point according to a center point corresponding to the current display picture and the coordinates of the center point of the target display picture;
determining a to-be-rotated angle corresponding to a central point corresponding to the current display picture according to the offset pixel point, the corresponding relation between the picture pixel and the rotation angle and a preset pixel transformation coefficient, wherein the pixel transformation coefficient is used for expressing the corresponding relation between the pixel point in the current display picture and the pixel point in the picture pixel;
and rotating according to the angle to be rotated, and moving the current display picture.
The corresponding relationship between the picture pixel and the rotation angle refers to a corresponding relationship between a unit pixel distance in a picture shot by a shooting system and the rotation angle of the shooting system, that is, each pixel corresponds to how many rotation angles, and the corresponding relationship between the picture pixel and the rotation angle can be obtained through a pre-test, for example, the corresponding relationship between the picture pixel and the rotation angle can be obtained through testing how many degrees the picture shot by the shooting system needs to rotate from the leftmost side to the rightmost side and how many degrees the picture needs to rotate from the uppermost side to the lowermost side, and then according to the rotation angle obtained through the test and the pixel size corresponding to the picture shot by the shooting system.
The offset pixel points are used for representing pixel point distances between a center point corresponding to the current display picture and a center point of the target display picture, and the pixel point distances refer to the number of pixel points which are different. The pixel transformation coefficient is used for expressing the corresponding relation between the pixel points in the current display picture and the pixel points in the picture pixels, namely the unit pixel points in the current display picture correspond to the pixel points in the picture pixels.
Specifically, the shooting system can obtain a central point corresponding to a current display picture and a corresponding relation between picture pixels and a rotation angle, determine offset pixel points between the central point corresponding to the current display picture and a central point of a target display picture according to the central point corresponding to the current display picture and coordinates of the central point of the target display picture, calculate corresponding offset pixel points in the picture pixels according to the offset pixel points and a preset pixel transformation coefficient, finally calculate a to-be-rotated angle according to the corresponding offset pixel points and the corresponding relation between the picture pixels and the rotation angle, rotate according to the to-be-rotated angle, and move the current display picture until the central point corresponding to the current display picture reaches the coordinates of the central point of the target display picture.
In this embodiment, the offset pixel point is determined according to the center point corresponding to the current display picture and the coordinates of the center point of the target display picture by acquiring the center point corresponding to the current display picture and the corresponding relationship between the picture pixel and the rotation angle, and the to-be-rotated angle corresponding to the center point corresponding to the current display picture can be determined according to the offset pixel point, the corresponding relationship between the picture pixel and the rotation angle, and the preset pixel transformation coefficient, so that the to-be-rotated angle is rotated according to the to-be-rotated angle.

when any coaxial coordinate point difference value in the second coordinate point difference value is larger than the corresponding coaxial coordinate point difference value in the first coordinate point difference value and the coaxial coordinate point difference value reaches a preset zooming triggering condition, amplifying a shot picture;
and when any coaxial coordinate point difference value in the second coordinate point difference value is not larger than the corresponding coaxial coordinate point difference value in the first coordinate point difference value and the coaxial coordinate point difference value reaches a preset zooming triggering condition, reducing the shot picture.
Specifically, according to a preset coordinate system and a coordinate origin, the photographing system can determine coordinate information of a coordinate point in a first touch coordinate and coordinate information of a coordinate point in a second touch coordinate, when the control mode is determined to be zooming, the photographing system indicates that a user operates the corresponding touch screen by using two fingers, the photographing system can determine a specific zooming mode by calculating a first coordinate point difference value between different coordinate points in the first touch coordinate, calculating a second coordinate point difference value between different coordinate points in the second touch coordinate, and comparing the first coordinate point difference value and a coaxial coordinate point difference value corresponding to the same coordinate axis in the second coordinate point difference value, when any coaxial coordinate point difference value exists in the second coordinate point difference value, the coaxial coordinate point difference value is greater than the corresponding coaxial coordinate point difference value in the first coordinate point difference value, and the coaxial coordinate point difference value reaches a preset zooming trigger condition, and when any coaxial coordinate point difference value in the second coordinate point difference value is not greater than the corresponding coaxial coordinate point difference value in the first coordinate point difference value and the coaxial coordinate point difference value reaches a preset zooming triggering condition, the shooting system reduces the shooting picture.
For example, the preset coordinate system may be an XOY coordinate system, the origin of coordinates may be any point on the touch screen, the coordinate information of the coordinate points in the first touch coordinates may be (X1, Y1) and (X2, Y2), the coordinate information of the coordinate points in the second touch coordinates may be (X3, Y3) and (X4, Y4), the photographing system calculates a first coordinate point difference value between different coordinate points in the first touch coordinates (X2-X1 and Y2-Y1), and calculating a second coordinate point difference value (X4-X3, Y4-Y3) between different coordinate points in the second touch coordinate, and comparing coaxial coordinate point difference values (X2-X1 and X4-X3, Y2-Y1 and Y4-Y3) corresponding to the same coordinate axis in the first coordinate point difference value and the second coordinate point difference value, thereby determining a specific zoom mode.
Further, the process of determining the specific zooming manner may specifically be: and when the X4-X3 is larger than the X2-X1 and the difference value between the X4-X3 and the X2-X1 reaches the preset zooming trigger condition, or the Y4-Y3 is larger than the Y2-Y1 and the difference value between the Y4-Y3 and the Y2-Y1 reaches the preset zooming trigger condition, determining that the specific zooming mode is zooming-up, and zooming-up the shot picture. And when the X4-X3 is not more than X2-X1 and the difference value between X4-X3 and X2-X1 reaches the preset zooming trigger condition, or Y4-Y3 is not more than Y2-Y1 and the difference value between Y4-Y3 and Y2-Y1 reaches the preset zooming trigger condition, determining that the specific zooming mode is zooming out, and zooming out the shooting picture.
