Description

The present invention relates to an image measuring machine and a program for touch-inputting commands from a touch panel display.

An image measuring device is used as a measuring device for measuring and evaluating the dimensions and shape of a measuring object by using an image obtained by imaging the object to be measured. 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.

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 a display or the like, and are also applied to image measuring machines. (See, for example, Patent Document 1).

In the input operation on the touch interface, command input is realized by using various gestures such as tap, double tap, long tap, flick, swipe, rotate, etc., which have different finger movements and contact states on the touch interface. Gestures are often done with one finger.

When a touch interface is used to input commands to an image measuring machine, some commands used in the image measuring machine involve physical movement or movement of the device such as stage movement or focus due to command execution. be. If a gesture performed with one finger is assigned to such a command input, the command is erroneously input due to an unintended contact with the touch panel display, and in the worst case, the measurement object and the device come into contact with each other. There is a risk of accidents.

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 with external devices, such as connecting to (Wide Area Network).
