Taking the horizontal moving component corresponding to the first motor and the vertical moving component corresponding to the second motor as an example, the horizontal moving component/vertical moving component of the touch operation may be first converted into the angle of the turntable rotation/the distance moved by the camera according to the setting relationship. Then, the angle of rotation of the first motor is calculated according to the angle of rotation of the turntable obtained by the conversion, and the angle of rotation of the second motor is calculated according to the distance of movement of the camera obtained by the conversion. Exemplarily, assuming that the horizontal movement component of the touch operation is x 1 , the vertical movement component is y 1 , the rotation of the turntable is x, and the curvature of the camera moving on the guide rail is y, then the relationship x=k 1 ×x 1 can be passed.

本实施例中，可以根据需要设定缩放增量的具体含义，例如，可以将触摸操作结束时刻和起始时刻触摸点距离的比值作为屏幕中所展示图像的缩放增量，也可以将触摸操作结束时刻和起始时刻触摸点的距离差与结束时刻(或起 始时刻)距离的比值作为屏幕中所展示图像的缩放增量，此处不作限制。可选的，可以将触摸操作结束时刻和起始时刻触摸点距离的比值作为屏幕中所展示图像的缩放增量，此时，示例性的，假设触摸操作起始时刻两触摸点的距离为a，触摸操作结束时刻两触摸点的距离为b，则此处触摸操作的缩放增量s＝b/a。In this embodiment, the specific meaning of the zoom increment may be set according to requirements. For example, the ratio of the touch operation end time and the start time touch point distance may be used as the zoom increment of the image displayed on the screen, or the touch operation may be performed. The difference between the end point and the start time touch point and the end time (or The ratio of the distance at the beginning is used as the scaling increment of the image displayed on the screen, and is not limited herein. Optionally, the ratio of the touch operation end time and the start time touch point distance may be used as a zoom increment of the image displayed on the screen. At this time, as an example, the distance between the two touch points at the start time of the touch operation is a. At the end of the touch operation, the distance between the two touch points is b, and the zoom increment of the touch operation here is s=b/a.
示例性的，在基于缩放增量调节触摸屏中所展示图像的大小时，可以首先基于缩放增量计算所展示图像的变换矩阵，并根据计算得到的变换矩阵确定变换后的图像的大小。例如，假设变换之前屏幕中所展示的图像为图像P0，变换之后屏幕中所展示的图像为图像P，图像P为图像P0在水平方向(X方向)移动距离m、竖直方向(Y方向)移动距离n、旋转角度0并放大a倍后得到的的图像，则可通过如下变换矩阵得到变换后的图像P：Exemplarily, when the size of the image displayed in the touch screen is adjusted based on the zoom increment, the transformation matrix of the displayed image may be first calculated based on the zoom increment, and the size of the transformed image is determined according to the calculated transformation matrix. For example, suppose that the image displayed on the screen before the transformation is the image P 0 , and the image displayed on the screen after the transformation is the image P, and the image P is the image P 0 moving in the horizontal direction (X direction) by the distance m and the vertical direction (Y) Direction) When the image is moved by the distance n, the rotation angle is 0, and the magnification is a, the transformed image P can be obtained by transforming the matrix as follows:
