Description

The present invention relates to an image measuring machine and a program capable of executing a command by touching a command input button displayed on a touch panel display.

An image measuring machine is used as a measuring device for measuring and evaluating the size and shape of a measuring object by using an image obtained by imaging the measuring object. The image measuring machine acquires edge information (positional coordinates, etc.) of the measurement target figure included in the captured image of the measurement target, and evaluates the shape and dimensions of the measurement target based on the edge information.

The edge information is often acquired by using an edge detection tool arranged in the captured image by the user's operation. The edge detection tool specifies the position and range to scan the edge according to the shape of the measurement target part, and various shapes according to the shape of the measurement target are provided as a function of the image measuring machine. .. For example, a rectangular shape suitable for edge detection of a straight line portion of an image, a circular shape suitable for edge detection of a circular image, and the like are typical.

In recent years, with the spread of touch panel displays, so-called touch interfaces have come to be widely used as user interfaces that can be operated by touching the display and are intuitively easy to use, and are also applied to image measuring machines (). For example, see Patent Document 1). In the touch interface, gesture input is adopted. For example, instead of clicking a button with a mouse, a command is input by touching the button with a finger or a touch pen.

By the way, in image measurement, in order to appropriately image the part of the object to be measured to be measured by the imaging means, the object to be measured is placed on a stage that can be moved in a two-dimensional or three-dimensional direction, and the image is taken by moving the stage. Adjust the position of the object to be measured with respect to the means. As a method of inputting a command to move the stage, for example, a button for moving the stage in a two-dimensional direction is displayed by superimposing it on the captured image of the measurement object displayed on the display, and each time the button is clicked. There is a method of moving the stage in a predetermined step (see, for example, Patent Document 2).

The conventional command input button exemplified in Patent Document 2 and the like is displayed at a fixed position on the display. Therefore, as a result of the user arranging the edge detection tool at an arbitrary position of the captured image of the object to be measured, there may be a case where the edge detection tool is arranged in the vicinity of the command input button. In such a case, especially when the display is a touch panel touch panel display, if an attempt is made to perform a touch input operation on either the edge detection tool or the command input button, the touch is erroneously detected on the other side, which is unintended. There is a risk of causing it to operate.

In view of such problems, it is an object of the present invention to provide an image measuring device and a program capable of avoiding false detection of touch input.

The image measuring machine of the present invention captures an image of the object to be measured, and uses an edge detection tool arranged by the user with respect to the captured image of the object to be measured displayed on the touch panel display, and the dimensions and shape of the object to be measured. It is an image measuring machine for measuring a predetermined command, and further includes a control means for controlling the display of a button for inputting a predetermined command on the touch panel display, and the control means detects an edge when the button is displayed on the touch panel display. Check if the tool is already placed, and if so, display the button at a position more than a predetermined threshold away from the position where the edge detection tool is placed.

When displaying the button on the touch panel display, the control means may check whether or not the edge detection tool is already arranged, and if not, display the button at a predetermined position on the touch panel display.

The control means may display the button on the touch panel display when a predetermined input operation is performed by the user or when the captured image is displayed on the touch panel display.

The control means is that when the button is displayed on the touch panel display and the edge detection tool is newly placed or the position where the edge detection tool has already been placed is changed, the display position of the button is changed by the edge detection tool. It may be changed to a position separated from the new arrangement position by a predetermined threshold value or more.

The control means may change the display position of the button to a predetermined position when the edge detection tool is deleted while both the button and the edge detection tool are displayed on the touch panel display.

The function of the control means may be realized by describing the function of the control means in a program and executing the function by a computer.

FIG. 3 is a diagram showing an example of a main window MW displayed on the touch panel display 144 by executing an image display program. In the main window MW, a plurality of windows are displayed as needed, including a work window WW in which the captured image WG of the captured object W is displayed.

〔Screen display〕
Next, the screen display displayed on the touch panel display 144 by the control program executed by the CPU 211 of the computer main body 141 will be described. In the following, a case of outputting a command for moving the stage 100 in response to an input operation to the button is illustrated, but the same can be applied to a case of outputting an operation command for each component of the housing 110.

The executed control program controls the display of the button for inputting a predetermined command on the touch panel display 144. The given command is optional. For example, FIG. 3 shows a case where a predetermined command is a motor drive command for moving the stage 100 in the ± X direction, the ± Y direction, and the ± Z direction, respectively, and the control executed at this time is shown. The program superimposes the captured image WG on the work window WW, and inputs the drive command of the motor for moving the stage 100 in each of the ± X direction, the ± Y direction, and the ± Z direction. Button BX, Button BY, And button BZ are displayed. To be precise, the button BX, the button BY, and the button BZ are divided into two buttons for inputting commands for moving the stage in the positive direction and the negative direction, respectively, as shown in FIG.

The executed control program may display the buttons BX, BY, and BZ, for example, when the captured image WG is displayed on the work window WW, or may not be displayed initially and is predetermined by the user. It may be displayed when the input operation of is performed. In this case, the predetermined input operation by the user is arbitrary. For example, the hamburger button BH as shown in FIG. 4 is displayed at the same time when the captured image WG is displayed, and the touch input operation is performed on the hamburger button BH. Taking the opportunity of what has been done, the buttons BX, BY, and BZ are displayed as shown in FIG.

When displaying the button on the work window WW, the executed control program scans the work window WW to confirm whether or not the edge detection tool T has already been placed on the captured image WG by the user.

Then, as shown in FIG. 4, if the edge detection tool T is not arranged, the buttons BX, BY, and BZ are displayed at arbitrary positions on the work window WW. The arbitrary position may be determined according to some rule, may be determined at random, or may be a predetermined position specified in advance. The method of determining the predetermined position is arbitrary, and may be, for example, a convenient position, specifically, a position where the edge detection tool T is difficult to be arranged (for example, a position shown in FIG. 3), or the user's dominant arm. It may be decided in consideration.

On the other hand, as shown in FIG. 5, when the edge detection tool T is already arranged, the buttons BX, BY, and BZ are separated from the arrangement position of the edge detection tool T by a predetermined threshold value or more as shown in FIG. Display at the position. The display position is arbitrary as long as it is separated from the arrangement position of the edge detection tool T by a predetermined threshold value or more, and may be determined according to some rule, for example, or may be determined randomly.

The executed control program is such that the buttons BX, BY, and BZ are displayed on the work window WW as shown in FIG. 3, and the edge detection tool T uses the buttons BX, BY as shown in FIG. 7, for example. , And when newly placed at a position that does not have a space between the buttons BX, BY, and BZ above a predetermined threshold, or between the buttons BX, BY, and BZ from another position that has already been placed. When the placement position is changed to a position that does not have a space between the buttons BX, BY, and BZ, the display position of the button BX, BY, and BZ is changed to a new placement position of the edge detection tool T (shown in FIG. 7), for example, as shown in FIG. It may be changed to a position separated from the position) by a predetermined threshold value or more.

In the executed control program, when the button BX, BY, and BZ and the edge detection tool T are both displayed as shown in FIG. 6, for example, and the edge detection tool T is deleted, the button BX, The display positions of BY and BZ may be changed to predetermined positions specified in advance. The method of determining the predetermined position is arbitrary, and may be, for example, a convenient position, specifically, a position where the edge detection tool T is difficult to be arranged (for example, a position shown in FIG. 3), or the user's dominant arm. It may be decided in consideration.

According to the image measuring machine of the present invention described above, when a button for inputting a predetermined command is displayed on the touch panel display, the button is displayed at a predetermined threshold interval between the touch panel display and the image measuring device, so that the command is input.
