Description

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

  An image measuring machine is used as a measuring device that measures and evaluates the size and shape of a measurement object using an image obtained by imaging the measurement object. The image measuring machine acquires edge information (such as position coordinates) 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 acquisition of edge information is often performed using an edge detection tool arranged in a captured image by a user operation. The edge detection tool is to specify the position and the 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, rectangular ones suitable for edge detection of linear portions of an image, and circular ones suitable for edge detection of circular images are representative.

  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 displays and are intuitively easy to use, and are also applied to image measuring machines ( For example, refer to Patent Document 1). In the touch interface, input by gesture is adopted, and 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, at the time of image measurement, in order to appropriately image the portion of the measurement object to be measured by the imaging means, the measurement object is mounted on a stage movable in two or three dimensions and imaged by moving the stage Adjust the position of the measurement object relative to the means. As a method of inputting a command for moving the stage, for example, a button for moving the stage in a two-dimensional direction is displayed superimposed on the captured image of the measurement object displayed on the display, each time the button is clicked once 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 predetermined 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 measurement object, there may occur a case where the user is arranged in the vicinity of the command input button. In such a case, particularly when the display is a touch panel display of a touch interface, when trying to perform a touch input operation to either the edge detection tool or the command input button, the touch is falsely detected in the other, which is unintended. There is a risk of making it work.

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 measurement object 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 shows 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 net measurement object. An image display program and a control program describing the function of the control means of the present invention are stored in these storage units, and these programs are read and executed by the CPU to realize functions such as the control means. .

  FIG. 3 is a view showing an example of the main window MW displayed on the touch panel display 144 by execution of the image display program. In the main window MW, a plurality of windows as needed, including a work window WW in which a captured image WG of the measured object W captured 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 addition, although the case where the command which moves the stage 100 with respect to the input operation to a button is output is illustrated below, it is applicable similarly also when outputting the operation command with respect to each component of the housing | casing 110.

  The executed control program controls the display on the touch panel display 144 of buttons for inputting a predetermined command. The predetermined command is optional. For example, FIG. 3 shows a case where a predetermined command is a drive command of a motor for moving the stage 100 in the ± X direction, ± Y direction, and ± Z direction, respectively. The program is a button BX for inputting a motor drive command for moving the stage 100 in the ± X direction, ± Y direction, and ± Z direction by superimposing on the work window WW on the captured image WG, and the button BY, And the button BZ is displayed. To be precise, as shown in FIG. 3, 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.

  The executed control program may display the buttons BX, BY, and BZ, for example, in response to the display of the captured image WG in the work window WW, or may not be displayed initially but may be predetermined by the user. It may be displayed when the input operation of is performed. In this case, a predetermined input operation by the user is optional. For example, a hamburger button BH as shown in FIG. 4 is simultaneously displayed when displaying the captured image WG, and a touch input operation is performed on the hamburger button BH. In response to the execution, buttons BX, BY, and BZ are displayed as shown in FIG.

  When displaying a button in the work window WW, the executed control program scans the work window WW to confirm whether the edge detection tool T has already been arranged in 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 an arbitrary position of the work window WW. The arbitrary position may be determined according to some rule, determined randomly, 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 disposed (for example, the position shown in FIG. 3). You may consider and decide.

  On the other hand, as shown in FIG. 5, when the edge detection tool T is already arranged, as shown in FIG. 6, the buttons BX, BY and BZ are separated from the arrangement position of the edge detection tool T by a predetermined threshold or more. Display on 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 or more, and for example, it may be determined according to some rule and may be determined randomly.

  For example, as shown in FIG. 7, the edge detection tool T has buttons BX and BY in the state where the buttons BX, BY and BZ are displayed in the work window WW as shown in FIG. , And BZ when it is newly arranged at a position not having a predetermined threshold or more, or from another position which has already been arranged, to a predetermined threshold or more between buttons BX, BY, and BZ. The display positions of the buttons BX, BY, and BZ are displayed, for example, as shown in FIG. The position may be changed to a position separated from the position by a predetermined threshold or more.

  When the edge detection tool T is deleted while the buttons BX, BY, and BZ and the edge detection tool T are displayed, for example, as shown in FIG. 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 disposed (for example, the position shown in FIG. 3). You may consider and decide.

  According to the image measuring machine of the present invention described above, when displaying a button for inputting a predetermined command on the touch panel display, the command is input in order to display with a predetermined threshold interval with the edge detection tool. False detection of touch input to each of the button and the edge detection tool can be avoided.
