[0015] In order to make the purpose, technical solutions and advantages of the present application more obvious, the example embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the example embodiments described herein. Based on the embodiments of the present application described in the present application, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present application.

[0016] First, refer to Figure 1 A method for measuring a touch screen according to an embodiment of the present application is described. The method is applied to a device for measuring a touch screen. The device for measuring a touch screen may be an ultrasonic imaging device, for example, the ultrasonic imaging device includes a touch display, and the touch display has a touch screen. Figure 1 FIG. 1 is a schematic flow chart of a method 100 for touch screen measurement according to an embodiment of the present application. Figure 1 As shown, the method 100 for touch screen measurement may include the following steps:

[0017] In step S110, a measurement instruction for a measurement object is received.

[0018] In an embodiment of the present application, when a user needs to measure a target object on the touch screen, a user can perform touch input through the touch screen or input a measurement instruction through other input devices (such as a mouse and keyboard, etc.) to trigger the display of a measurement cursor. Exemplarily, the measurement instruction may include a drag instruction, a long press instruction, a click instruction, etc., for the target object to be measured (measurement object).

[0019] In step S120, a measurement cursor is displayed on the touch screen based on the measurement instruction, wherein the measurement cursor includes a first icon representing a measurement focus, a second icon representing a first touch point, and a third icon representing a second touch point, and the first icon, the second icon, and the third icon are separated from each other.

[0020] In an embodiment of the present application, in response to receiving a measurement instruction in step S110, a measurement cursor is displayed on the touch screen in step S120. In an embodiment of the present application, the measurement cursor displayed on the touch screen includes a measurement focus and a touch point, wherein the measurement focus and the touch point are separated from each other, so that when the user's hand moves the measurement cursor to the target measurement position by touching the touch point, the measurement focus will not be blocked and cannot be accurately positioned because the measurement focus is not located, because the hand is located on the touch point, and the touch point and the measurement focus are not in the same position, and the user can clearly see the position of the measurement focus in the process of controlling the movement of the measurement cursor by the touch point, so that the measurement focus of the measurement cursor can be accurately moved to the target measurement position to achieve accurate measurement.

[0021] Furthermore, in an embodiment of the present application, the measurement cursor displayed on the touch screen includes two touch points, one of which is used to coarsely adjust the position of the measurement cursor, and the other is used to finely adjust the position of the measurement cursor. This allows the user to combine coarse adjustment and fine adjustment to further accurately move the measurement cursor, thereby achieving precise positioning of the measurement cursor and precise measurement of the measurement object.

[0022] In an embodiment of the present application, in order to distinguish from each other, the measurement focus included in the measurement cursor displayed in step S120 may be represented by a first icon, and the first touch point of the two touch points included in the measurement cursor displayed in step S120 for controlling the coarse adjustment of the measurement cursor position may be represented by a second icon, wherein the first icon has a first pattern, the second icon has a second pattern, and the first pattern and the second pattern may be different patterns. In one example, the first icon representing the measurement focus may be an icon with a cross pattern, and the second icon representing the first touch point may be an icon with a hand pattern. In another example, the first icon representing the measurement focus may be an icon with a cross pattern, and the second icon representing the first touch point may be an icon with an arrow pattern. In yet another example, the first icon representing the measurement focus may be an icon with an arrow pattern, and the second icon representing the first touch point may be an icon with a hand pattern. In other examples, the first icon representing the measurement focus and the second icon representing the first touch point may also be patterns of other shapes that can be distinguished from each other.

[0023] In an embodiment of the present application, the second touch point for controlling the fine adjustment of the position of the measurement cursor among the two touch points included in the measurement cursor displayed in step S120 may be represented by a third icon. In an embodiment of the present application, the third icon may include at least one direction icon, each direction icon represents the direction in which the measurement cursor is fine-tuned, and each direction icon can be touched by a user to fine-tune the position of the measurement cursor along the corresponding direction. In one example, the third icon representing the second touch point for controlling the fine adjustment of the position of the measurement cursor may include eight direction icons, namely, an upward direction icon, an upper left direction icon, an upper right direction icon, a downward direction icon, a lower left direction icon, a lower right direction icon, a left direction icon, and a right direction icon, based on which the position of the measurement cursor can be fine-tuned along eight directions through the eight direction icons. In another example, the third icon representing the second touch point for controlling the fine adjustment of the position of the measurement cursor may include four direction icons, namely, an upward direction icon, a downward direction icon, a left direction icon, and a right direction icon, based on which the position of the measurement cursor can be fine-tuned along four directions through the four direction icons.

[0024] In an embodiment of the present application, the aforementioned third icon (for example, four direction icons or eight direction icons) representing the second touch point for controlling fine adjustment of the measurement cursor position can be located around the second icon (that is, the icon representing the first touch point for controlling coarse adjustment of the measurement cursor position), or can also be located at other suitable positions, such as around the first icon representing the measurement focus.

[0025] In another embodiment of the present application, the aforementioned third icon representing the second touch point for controlling the fine adjustment of the measurement cursor position may also be a circular adjustment icon, and touching different positions of the circular adjustment icon indicates fine adjustment of the position of the measurement cursor in the corresponding direction. The circular adjustment icon can adjust the position of the measurement cursor in different directions with only one icon. In another embodiment of the present application, the aforementioned third icon representing the second touch point for controlling the fine adjustment of the measurement cursor position may also be a magnifying glass adjustment icon, and touching the magnifying glass adjustment icon can magnify the measurement cursor for display, thereby facilitating more precise adjustment of the position of the measurement cursor. In other embodiments, the third icon representing the second touch point for controlling the fine adjustment of the measurement cursor position may also include any other icons capable of fine-tuning the measurement cursor position, for example, the third icon of the second touch point for controlling the fine adjustment of the measurement cursor position may be displayed elsewhere on the screen (for example, not near the measurement focus of the measurement cursor and the first touch point), implemented with an independent button, and so on.

[0026] In an embodiment of the present application, adjustment of the measurement cursor position based on the second touch point for controlling fine-tuning of the measurement cursor position may include pixel-level adjustment, that is, when the user moves the measurement cursor by touching the second touch point, the step size of each movement may be a distance of one pixel, which can achieve very precise position adjustment.

[0027] Combine the following Figure 2 and Figure 3 An exemplary schematic diagram of a measurement cursor and its operation displayed by a method for touch screen measurement according to an embodiment of the present application is described. Figure 2 A schematic diagram showing an example of a measuring cursor provided in a method for touch screen measurement according to an embodiment of the present application is shown, Figure 3 A schematic diagram showing the operation of an example of a measurement cursor provided in a method for touch screen measurement according to an embodiment of the present application is shown.

[0028] like Figure 2 As shown, the measurement cursor includes a cross-shaped pattern icon indicating the measurement focus, a hand-shaped pattern icon indicating a first touch point for controlling the coarse adjustment of the measurement cursor position, and a direction icon including up, down, left and back directions indicating a second touch point for controlling the fine adjustment of the measurement cursor position. Figure 2 In the example shown, the icon representing the measurement focus is designed as a cross pattern, the icon representing the first touch point for controlling the coarse adjustment of the measurement cursor position is designed as a hand pattern, and the icon representing the second touch point for controlling the fine adjustment of the measurement cursor position is designed to include four direction icons, and the four direction icons are located around the hand pattern icon. It should be understood that such pattern design and its position design are merely exemplary.

[0029] like Figure 2 As shown in the figure, the cross-shaped pattern icon representing the measurement focus, the hand-shaped icon representing the first touch point for controlling the coarse adjustment of the measurement cursor position, and the direction icon representing the second touch point for controlling the fine adjustment of the measurement cursor position are separated from each other. The cross-shaped pattern icon representing the measurement focus is located in the upper left corner, the hand-shaped icon representing the first touch point for controlling the coarse adjustment of the measurement cursor position is located in the middle of the measurement cursor, and the direction icon representing the second touch point for controlling the fine adjustment of the measurement cursor position is located around the first touch point. Since the touch points and the measurement focus are separated from each other, when the user's hand moves the measurement cursor to the target measurement position by touching the hand-shaped icon representing the first touch point or the direction icon representing the second touch point, the measurement focus will not be blocked and cannot be accurately positioned. Figure 3As shown, because the hand is located on the hand-shaped icon representing the first touch point or on the direction icon representing the second touch point, the touch point and the measurement focus are not located at the same position. The user can clearly see the position of the measurement focus during the process of controlling the movement of the measurement cursor by the touch point, thereby being able to accurately move the measurement focus of the measurement cursor to the target measurement position to achieve accurate measurement, as described above. In addition, Figure 3 As shown, when a user touches a hand icon representing a first touch point or a direction icon representing a second touch point, it is not necessary to touch the icon itself, but it is possible to touch the icon by touching a small sensing area near the icon, such as Figure 3 The rectangular area around the four direction icons shown can be touched to realize touch control of the direction icons, which can further improve the user experience.

[0030] Based on the above-mentioned measurement cursor, the measurement focus of the measurement cursor can be moved to the target measurement position according to a user instruction, as will be described in subsequent steps of the method 100 for touch screen measurement according to an embodiment of the present application.

[0031] In step S130 , a first touch control instruction for the second icon is received, and the measuring cursor is moved based on the first touch control instruction.

[0032] In the embodiment of the present application, generally the user first quickly adjusts the position of the measurement cursor by touching the second icon representing the first touch point used to control the coarse adjustment of the measurement cursor position, and thus can drag the measurement cursor (the measurement focus in) to the desired target measurement position (near) through the first touch instruction, i.e., the instruction to move the measurement cursor by touching the second icon. It should be understood that the term "first touch instruction" here is named so only to distinguish it from the "second touch instruction" to be described below, and has no other limiting meaning.

[0033] In step S140 , a second touch control instruction for the third icon is received, and the measurement cursor is fine-tuned based on the second touch control instruction so that the first icon moves to a target measurement position.

[0034] In an embodiment of the present application, after a general user quickly adjusts the position of the measurement cursor by touching the second icon representing the first touch point used to control the coarse adjustment of the measurement cursor position, the user can finely adjust the position of the measurement cursor by touching (for example, clicking) the third icon representing the second touch point used to control the coarse adjustment of the measurement cursor position. Therefore, the measurement cursor (the measurement focus in the measurement cursor) can be accurately moved to the desired target measurement position by the second touch instruction, that is, the instruction to touch the third icon to slightly move the measurement cursor, thereby achieving accurate measurement of the target measurement position.

[0035] It should be understood that in the embodiment of the present application, at least one of step S130 and step S140 may not be necessary, because the measurement cursor (the measurement focus in) provided on the display screen may fall exactly at the target measurement position without moving, and accurate measurement can be performed directly at the target measurement position. In addition, the measurement cursor may also be displayed at the initial position of the system default or user-defined, and after receiving the measurement instruction for the measurement object, the measurement cursor may be automatically moved from the initial position to a position near the measurement object for display.

[0036] Based on the above description, the method, device and storage medium for touch screen measurement according to the embodiments of the present application provide a measurement cursor in which the touch point and the measurement focus are separated from each other, so that the touch of the hand during operation will not block the measurement focus, which is conducive to achieving precise positioning; in addition, the measurement cursor includes two touch points, which can respectively support coarse adjustment and fine adjustment of the measurement cursor position movement, thereby achieving precise adjustment of the measurement cursor position and improving measurement accuracy.
