JP6985157B2 - Image measuring machines, tool editing methods, and programs - Google Patents

Description

The present invention relates to an image measuring machine that edits an edge detection tool by an input operation on a touch panel display, a tool editing method, and a program.

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. 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.

In an image measuring machine that uses a touch panel display, as a method for facilitating editing such as enlargement / reduction / rotation of the edge detection tool displayed on the touch panel display, for example, editing handles are further displayed at the four corners of the edge detection tool. However, there is a method of editing by operating the touch panel display with a finger or the like on the editing handle. Another way to use the editing handle is to pull out the editing handle with a leader line so that multiple editing handles are not crowded together or the editing handle overlaps with the captured image, making it difficult to operate. Therefore, a technique for improving the operability of a desired editing handle is disclosed (see, for example, Patent Document 1).

In addition, as a method that does not use the editing handle, for example, by directly performing a gesture input operation such as pinch / unpinch on the edge detection tool displayed on the touch panel display, the edge detection tool can be reduced / enlarged. There are ways to make it possible.

Japanese Unexamined Patent Publication No. 2016-173703

The method of using the editing handle is difficult to operate intuitively because the procedure is not simple. In addition, the method of inputting gestures directly to the edge detection tool is, for example, when the edge detection tool is too large or too small for the size that is easy to input with a human finger, or when multiple edge detection tools are crowded. If so, it may not be easy to perform an input operation directly to the intended edge detection tool.

In view of such problems, it is an object of the present invention to provide an image measuring machine, a tool editing method, and a program in which the editing operation of the edge detection tool is intuitive, simple, and easy.

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. The tool editing gesture, which is an image measuring machine for measuring the edge detection tool displayed on the touch panel display in the selected state and is a gesture for editing the edge detection tool at an arbitrary position on the touch panel display in the selected state. It is provided with a control means for performing editing corresponding to the tool editing gesture to the edge detection tool by contact input.

In the tool editing method of the present invention, the measurement object is imaged, and the size and shape of the measurement object are measured by using an edge detection tool arranged by the user with respect to the captured image of the measurement object displayed on the touch panel display. This is a tool editing method for editing the edge detection tool when measuring, at a selection step in which the edge detection tool displayed on the touch panel display is selected, and at an arbitrary position on the touch panel display in the selected state. By touch-inputting a tool editing gesture, which is a gesture for editing the edge detection tool, an editing step of making an edit corresponding to the tool editing gesture to the edge detection tool is executed.

The tool editing gesture may be, for example, pinch and unpinch, and the edit corresponding to the pinch and unpinch may be the reduction and enlargement of the edge detection tool.

Further, the tool editing gesture may be, for example, rotation, and the editing corresponding to rotation may be rotation of the edge detection tool.

Further, the tool editing gesture may be, for example, a swipe performed in a state of simultaneous contact of two points, and the editing corresponding to the swipe performed in a state of simultaneous contact of two points may be translated in the direction of the swipe of the edge detection tool. ..

In the present invention, the edge detection tool may be selected by contact inputting a tool selection gesture, which is a gesture for selecting the edge detection tool, on the edge detection tool displayed on the touch panel display. Also, the tool selection gesture should be a tap.

The function of the control means may be realized by describing the function of the control means of the image measuring machine of the present invention in a program and executing the function by a computer.

[Configuration of image measuring machine]
FIG. 1 shows an example of the overall configuration of an image measuring machine. The image measuring machine 1 includes a stage 100, a housing 110, and a computer system 140. The upper surface of the stage 100 is arranged so as to coincide with the horizontal plane, and the object W to be measured is placed on the upper surface. The stage 100 can be moved at least in the X-axis direction and the Y-axis direction by rotating the handle 101 or 102. The housing 110 includes an optical system including a lighting device such as transmission lighting and epi-illumination and an image pickup element, and the housing 110 itself can be moved in the Z-axis direction together with the optical system and the image pickup element by rotating the handle 112. And.

The computer system 140 controls the stage 100 and the housing 110 to acquire a captured image of the measurement target W, and provides an operation environment to the user. The computer system 140 includes, for example, a computer body 141, a keyboard 142, a mouse 143, and a touch panel display 144. The computer main body 141 controls the operation 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 acquires and calculates the information of the measurement object W based on the signals output from the stage 100 and the housing 110, and performs a process of displaying the calculation result on the touch panel display 144. The keyboard 142 and the mouse 143 are input means for the computer body 141. The touch panel display 144 functions not only as a display means for displaying an image output by the computer main body, but also as an input means for detecting an operation due to contact with the screen and inputting the image to the computer main body 141.

FIG. 2 shows a functional block diagram of the computer system 140. As functional blocks of the computer system 140, a CPU (Central Processing Unit) 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 part by executing various programs. The interface 212, for example, takes in information sent from the stage 100 or the housing 110 into the computer system 140, sends information from the computer system 140 to the stage 100 or the housing 110, and connects the computer system 140 to a LAN (Local Area Network) or WAN. It is a part that inputs and outputs information to and from external devices, such as connecting to (Wide Area Network).

The output unit 213 outputs the result processed by the computer system 140. As the output unit 213, for example, the 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, and the like 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 the main storage unit 215, for example, a RAM (Random Access Memory) is used. As a part of the main storage unit 215, a part of the sub storage unit 216 may be used. For the sub-storage unit 216, for example, an HDD (Hard disk drive) or SSD (Solid State Drive) is used. The sub-storage unit 216 may be an external storage device connected via a net measurement object. An image display program and a control program in which the functions of the control means in the present invention are described are stored in these storage units, and the functions of the control means and the like are realized by reading and executing these programs by the CPU. ..

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. Note that FIG. 3 shows a state in which the rectangular edge detection tool T arranged in advance by the input operation by the user is superimposed and displayed on the captured image WG.

[Editing the edge detection tool by executing the control program]
The control program executed by the CPU 211 of the computer main body 141 is a gesture for the user to select the edge detection tool T for the edge detection tool T displayed on the touch panel display 144 as shown in FIG. When a certain tool selection gesture is contact-input and a signal output from the touch panel display 144 is detected based on the tool selection gesture, the edge detection tool T is selected (selection step).

When a plurality of edge detection tools T are arranged, the user selects one of the edge detection tools T, contacts and inputs a tool selection gesture to the edge detection tool T, and uses the edge detection tool. In the selected state, the editing target is specified to the edge detection tool T.

As the tool selection gesture, any gesture such as tap, double tap, or long tap may be adopted. Further, it is desirable that the selected state of the edge detection tool T can be visually recognized, and it is preferable that the selection state can be recognized by any expression such as changing the color of the edge detection tool or adding the display of the editing handle. FIG. 5 is an example in which the display of “□” indicating the editing handle H is added to the four corners of the rectangular edge detection tool to make it recognizable.

Further, in the control program executed by the CPU 211, a tool editing gesture, which is a gesture for editing the edge detection tool T at an arbitrary position on the touch panel display 144, is touch-input by the user in the selected state of the edge detection tool T. When the signal output from the touch panel display 144 is detected based on the tool edit gesture, the edge detection tool T is edited according to the tool edit gesture and reflected in the display of the edge detection tool T on the touch panel display 144 (edit step). ..

Tool editing gestures include pinch (operation to narrow the distance between two contact positions), unpinch (operation to increase the distance between two contact positions), rotate (operation to change the angle of a straight line connecting two contact positions), and Any gesture different from the tool selection gesture, such as a swipe (operation to move the contact position) performed in the state of simultaneous contact of two points, may be adopted. However, it is desirable to adopt a gesture suitable for the editing mode of the edge detection tool T so that the input can be intuitively performed. For example, the edits corresponding to pinch and unpinch are reduced and enlarged, and the edits corresponding to rotate are rotated. Further, the editing corresponding to the swipe performed in the state of simultaneous contact of two points is defined as translation in the swipe direction. It is also preferable that the edge detection tool T can be deleted by the tool editing gesture. As a tool editing gesture corresponding to the deletion of the edge detection tool T, for example, an operation in which the tool moves out of the frame of the work window WW by a swipe performed in a state of simultaneous contact of two points, and two points at a speed equal to or higher than a predetermined threshold value. It is advisable to assign a swipe operation or the like performed in a simultaneous contact state. FIG. 6 is an example in which unpinch is adopted for editing in which the edge detection tool T is enlarged horizontally.

The input position of the tool editing gesture may not be an arbitrary position on the touch panel display 144, but may be within a specific area in consideration of the display position and operability of the captured image WG.

The correspondence between the tool selection gesture and the selected state and the correspondence between the tool editing gesture and the editing mode may be stored in the sub-storage unit 216 and referred to when the control program is executed, or the control program itself. You may write it in.

In the selected state of the edge detection tool T, it may be editable only by inputting the tool edit gesture, or it may be editable by the edit handle.

An image measuring machine equipped with a control means whose function is realized by executing a control program in which a tool editing method including the above selection step and an editing step is written is executed by a CPU, and an intuition according to the editing mode of the edge detection tool. It is possible to input a specific gesture and edit with a small number of steps. In addition, regardless of the size and density of the edge detection tool, it is possible to reliably perform an editing operation on the selected edge detection tool.
