Description

  The present invention relates to a position specification method for specifying a position in a screen displayed on a touch panel display by touch input.

  An image measuring machine is used as a measuring device which measures and evaluates a size and a shape of a work using an image obtained by imaging an object to be measured (hereinafter, referred to as "work"). The image measuring machine acquires edge information (such as position coordinates) of the measurement target figure included in the image of the imaged workpiece, and evaluates the shape and dimensions of the workpiece based on the edge information.

  By the way, in recent years, with the spread of touch panel displays, so-called touch interfaces have come to be widely used as intuitive and easy-to-use user interfaces that can be operated by touching displays etc. (See, for example, Patent Document 1).

  While the touch interface enables intuitive operation, it is difficult to accurately specify the position intended by the user when trying to specify a fine position in the display screen. That is, in a conventional input means such as a mouse, when specifying a position in the display screen, the cursor displayed on the screen is moved using the mouse etc., and the cursor is accurately positioned at the intended position Can be specified. On the other hand, in the touch interface, the center of gravity of the area in contact with the display is usually designated by a finger or a pen point. Since the center of gravity of this contact area is hidden from the user behind the finger or the pen tip, the user can not accurately know the position designated by the user, and the intended position is accurately determined. It is not easy to specify.

  Hereinafter, embodiments of the present invention will be described based on the drawings. In the following description, the same members are denoted by the same reference numerals, and the description of the members once described will be omitted as appropriate.

[Configuration of image measuring machine]
The image measuring device 1 shown in FIG. 1 includes a stage 100, a housing 110, and a computer system 140. The stage 100 is disposed such that the upper surface thereof coincides with the horizontal plane, and the work W is placed on the upper surface. The stage 100 can be moved in the X-axis direction and the Y-axis direction by rotating the handles 101 and 102. The housing 110 includes an optical system including an illumination device such as transmissive illumination and epi-illumination and an imaging device, and the housing 110 itself can be moved in the Z-axis direction together with the optical system and the imaging device by rotating the handle 112 Do.

  The computer system 140 controls the stage 100 and the housing 110 to acquire a captured image of the work W, and provides the user with an operation environment. The computer system 140 includes, for example, a computer main body 141, a keyboard 142, a mouse 143, and a touch panel display 144. The computer main body 141 controls operations of the stage 100 and the housing 110 by a circuit (hardware) such as a control board and a program (software) executed by the CPU. Further, the computer main body 141 performs processing of acquiring and calculating information of the work W based on the signals output from the stage 100 and the housing 110 and displaying the calculation result on the touch panel display 144. The keyboard 142 and the mouse 143 are input means for the computer main body 141. The touch panel display 144 functions as a display unit that displays an image output from the computer main body, and also functions as an input unit that detects an operation by a touch on the screen and inputs the operation to the computer main body 141.

  FIG. 2 is a functional block diagram of computer system 140. As functional blocks of the computer system 140, a central processing unit (CPU) 211, an interface 212, an output unit 213, an input unit 214, a main storage unit 215, and a sub storage unit 216 are provided.

  The CPU 211 controls each unit by executing various programs. The interface 212 takes in, for example, information sent from the stage 100 or the case 110 into the computer system 140, sends information from the computer system 140 to the stage 100 or the case 110, LAN (Local Area Network) or WAN for the computer system 140 It is a part that performs information input / output with an external device, which has a role of connecting to (Wide Area Network), etc.

  The output unit 213 outputs the result processed by the computer system 140. As the output unit 213, for example, a touch panel display 144 shown in FIG. 1, a printer or the like is used. The input unit 214 receives information from the operator. For the input unit 214, for example, the keyboard 142, the mouse 143, the touch panel display 144, etc. shown in FIG. 1 are used. Further, the input unit 214 includes a function of reading the information recorded on the recording medium MM.

  For example, a random access memory (RAM) is used for the main storage unit 215. As a part of the main storage unit 215, a part of the secondary storage unit 216 may be used. For the secondary storage unit 216, for example, a hard disk drive (HDD) or a solid state drive (SSD) is used. The secondary storage unit 216 may be an external storage device connected via a network.

〔Screen display〕
Next, the screen display displayed on the touch panel display 144 by the program (measurement application software) executed by the CPU 211 of the computer main body 141 will be described.

  FIG. 3 is a view showing an example of a display screen displayed on the touch panel display 144 by execution of a program. As shown in FIG. 3, the touch panel display 144 displays a main window MW. In addition, a plurality of windows (first window W1 to ninth window W9) are displayed in the main window MW. A menu and icons for various operations and settings are also displayed above the main window MW. In the present embodiment, an example in which eight windows are displayed is shown as an example, but window display other than eight can be performed as needed. Also, the layout of each window can be freely changed by the user's operation.

  In the first window W1, the image WG of the work W captured by the image measuring device 1 is displayed. For example, the user performs an operation of selecting an icon with the mouse 143 or narrowing or widening the contact position by two fingers with respect to the display area of the first window W1 on the touch panel display 144 (so-called pinch out / pinch in) The image WG of the work W can be scaled up / down by Further, the position of the image WG of the work W displayed in the first window W1 can be adjusted by an operation (so-called swipe) of sliding a finger in a state of touching the display area of the first window W1 in the touch panel display 144.

  In the second window W2, icons of tools selectable by the user are displayed. The tool icon is provided corresponding to the designation method for designating the measurement point from the image WG of the workpiece W.

  In the third window W3, icons of functions selectable by the user are displayed. The icon of the function is provided for each measurement method. As a measurement method, for example, a method of measuring the coordinates of one point, a method of measuring the length of a straight line, a method of measuring a circle, a method of measuring an ellipse, a method of measuring a square hole, a long hole Methods, methods of measuring pitch, methods of measuring the intersection of two lines, etc. may be mentioned.

  In the fourth window W4, guidance representing an operation procedure related to measurement and a pattern G corresponding to the operation step are displayed.

  In the fifth window W5, various sliders for controlling the illumination to be applied to the work W are displayed. The user can apply desired illumination to the work W by operating the slider.

  In the sixth window W6, XY coordinate values of the stage 100 are displayed. The XY coordinate values displayed in the sixth window W6 are the coordinate in the X-axis direction and the coordinate in the Y-axis direction of the stage 100 with respect to a predetermined origin.

  The seventh window W7 displays the tolerance determination result. That is, in the seventh window W7, when the measurement method capable of determining the tolerance is selected, the result is displayed.

  The eighth window W8 displays the measurement result. That is, in the eighth window W8, when a measurement method for obtaining a measurement result by a predetermined calculation is selected, the measurement result is displayed. The details of the display of the tolerance determination result of the seventh window W7 and the measurement result of the eighth window W8 are not shown.

[Position specification processing]
Subsequently, a position designation process realized by a program executed by the computer system 140 will be described. FIG. 4 shows a flowchart of position designation processing. The positioning process is initiated in response to selecting a function and a tool. In this example, the case where the coordinate measurement of one point is selected as the function and the manual position specification tool is selected as the measurement point specification method will be described as an example. FIG. 5 shows an example of an initial screen of the first window W1 before the start of position specification processing. When the process is started, the computer system 140 continuously acquires the touch position on the touch panel display 144 to recognize various touch operations.

  When the computer system 140 starts the process, the computer system 140 determines whether or not the enlargement instruction operation by the user has been detected (step S100). The “magnification instructing operation” is a predetermined operation performed to magnify and display the periphery of a position to be designated by the user. In this example, an operation in which the user taps a desired position in the first window W1 is referred to as "magnification instructing operation".

  If the computer system 140 does not detect the enlargement instruction operation (Step S100; No), the process returns to Step S100, and Step S100 is repeated until the enlargement instruction operation is detected. That is, the computer system 140 will wait for the user to tap in the first window W1. As shown in FIG. 6, when the user taps the vicinity of the position to be designated in the first window W1, the computer system 140 detects this as an enlargement instruction operation (step S100; Yes). Then, as shown in FIG. 7, the computer system 140 enlarges and displays the periphery of the position at which the enlargement instruction operation has been performed (that is, the position tapped by the user) in the ninth window W9 that is an enlargement screen ( Step S110). In the present example, the ninth window W9 is displayed as a so-called pop-up window that is newly displayed automatically when the enlargement instruction operation is detected. The size, display position, and the like of the ninth window W9 are set in advance, and the center of the enlarged screen is a position at which the enlargement instruction operation is detected. Further, it is assumed that the enlargement ratio (ratio of the scale of the initial screen to the enlargement screen) at the time of displaying in the ninth window W9 is also set in advance.

  Subsequently, computer system 140 determines whether or not a position designation operation has been detected (step S120). The “position designation operation” is a predetermined operation performed to designate a position desired by the user in the enlarged screen. In this example, an operation in which the user taps a position to be designated in the ninth window W9 is a position designation operation.

  When the computer system 140 does not detect the position designation operation (Step S120; No), the process returns to Step S120, and Step S120 is repeated until the position designation operation is detected. That is, the computer system 140 waits for the user to tap in the ninth window W9. As shown in FIG. 8, when the user taps a position to be designated in the ninth window W9, the computer system 140 detects this as a position designation operation (step S120: Yes). Then, the computer system 140 acquires the position at which the position specification operation has been performed (that is, the position tapped by the user) as the specified position (step S130).

  Subsequently, the computer system 140 closes the ninth window W9 and, at the position of the first window W1 corresponding to the designated position in the ninth window W9, marks M (for example, x (cross) mark shown in FIG. ) Is displayed (step S140). End the process.

  According to the procedure described above, it is possible to realize the position designation method and program suitable for the operation on the touch panel display 144. In particular, accurate position specification can be performed by touch input with a finger or a stylus pen.

  Although the embodiment has been described above, the present invention is not limited to this example. For example, the position designation method and program described above are not limited to the image measurement device application, and can be applied to various applications involving an operation of designating a position in the screen.

  In the above embodiment, the operation of tapping near the position to be designated in the first window W1 has been described as the enlargement instruction operation, but the enlargement instruction operation is not limited to this. For example, an operation (so-called long press) in which a user keeps touching a predetermined time (for example, about 1 second to 2 seconds) near a position to be designated may be used as the enlargement instruction operation. By setting the long press as the enlargement instruction operation, the computer system 140 is not detected as the enlargement instruction operation when the user unintentionally touches the screen lightly, and thus unnecessary processing and operation are performed. Can be suppressed.

  Further, a so-called slide operation of moving the contact position in the vicinity of the position to be designated by a predetermined distance or more may be used as the enlargement instruction operation. By setting the slide operation as the enlargement instruction operation, the computer system 140 does not detect the enlargement instruction operation when the user unintentionally touches the screen lightly, and thus unnecessary processing and operation are performed. Can be suppressed.

  In addition, an operation of sliding the contact position in a predetermined pattern such as characters near the position to be designated may be used as the enlargement instruction operation. The predetermined pattern may be Z-shaped initial of Zoom. By setting the operation of sliding the contact position in such a predetermined pattern as the enlargement instruction operation, the computer system 140 detects the enlargement instruction operation as if the user unintentionally touched the screen lightly. Since it is lose | eliminated, it can suppress that an unnecessary process and operation are performed.

  When the operation accompanied by the sliding of the contact position is used as the enlargement instruction operation, it is preferable to determine the range and the enlargement ratio to be displayed on the enlargement screen based on the start point and the end point of the slide. For example, assuming that the right direction in the screen is the x-axis positive direction and the upper direction is the y-axis positive direction, and the coordinates of the slide start point are (x1, y1) and the end point coordinates are (x2, y2), the start point A rectangular range having four points of the end point, (x1, y2), and (x2, y1) as vertices may be displayed as the enlarged screen. Alternatively, the size of the enlarged screen may be fixed, and the enlarged screen may be displayed at an enlargement ratio at which the height or width of the rectangle having the above four points as vertices corresponds to the height or width of the fixed size enlarged screen. The center of the enlarged screen may be the center of the slide start and end points ((x1 + x2) / 2, (y1 + y2) / 2).

  In the above embodiment, the operation of tapping a desired position in the enlarged screen (the ninth window W9) has been described as a position designating operation, but the position designating operation is not limited to this, and during the second window W2 The operation suitable for the tool that can be selected by the icon may be taken as the position specification operation according to each tool.

  In the above embodiment, the ninth window W9 displayed as the enlarged screen is superimposed on the first window W1 and is displayed smaller than the first window in FIG. 7 and the like. The display method is not limited to this. In the configuration in which the enlarged screen is displayed as the pop-up window as in the above embodiment, the pop-up window may be displayed at a position not overlapping the first window W1 or may be displayed larger than the first window W1. Also, the enlarged screen may be displayed by a method other than the pop-up window. For example, any existing window from the first window W1 to the eighth window W8 may be temporarily used as the enlarged screen. Further, the enlarged screen may be displayed on the entire screen of the touch panel display 144.

  Further, in the above embodiment, the operation of tapping the position to be designated in the enlarged screen (the ninth window W9) has been described as the position designation operation, but the position designation operation is not limited to this. For example, an operation (a long press or release of a finger or the like after a slide) in which the contact is ended after continuing the contact for a predetermined time or more may be used as the position designation operation. In this case, it may be acquired as the designated position when the contact is ended (that is, the position at which the contact was last). At this time, instead of the position where the contact is detected, a predetermined relative position (for example, a position 2 cm above the contact position) based on the position where the contact is detected is acquired as the designated position. It is also good. When the position where the contact is detected and the position to be acquired as the designated position are different as described above, the cursor is displayed at the relative position on the enlarged screen with respect to the contact position so that the user can visually recognize that position.
