2. Description of the Related Art As a measuring device for measuring the surface properties of an object to be measured, a manual measuring device for performing a manual measurement and an automatic measuring device for performing an automatic measurement are used. In the measurement data processing and the automatic measurement processing, a measurement part program created in advance is used.

[0003] There are roughly two methods for creating the measurement part program. One of them is a so-called playback method. For example, an object to be measured is actually placed on a three-dimensional measuring machine, and measurement is performed while operating a joystick to store those measurement procedures. To convert to a measurement part program. Another way is
CAT (Computer Aided Testin
g) A method of automatically generating a measurement part program by the system. This is CAD (Computer)
A three-dimensional model of the device under test is created from the Aided Design data, and a measurement part program is automatically or manually generated for the model.

In order to edit the measurement part program created in this way, a method is known in which a model is generated in virtual space from the measurement part program by a solid modeler, and the measurement part program is edited using the model. (See JP-A-10-300457).

[0005]

However, since a symbol language is used in the measurement part program as shown in FIG. 6, if it is desired to confirm the contents of this program during actual measurement, the measurement part program You need to know the meaning of the symbol and the grammar of the command. Furthermore, the symbols and grammar may be different for each type of measuring machine, and learning them requires a great deal of labor. Therefore, even with an automatic measuring machine, there is a problem that it is difficult to master the automatic measuring machine until the user learns the measurement part program and masters it. In addition, it is difficult to understand the contents of the measurement part program, which may cause a measurement error of the measured object.

The present invention has been made in order to solve such a problem, and it is an object of the present invention to provide a method of displaying the contents of a measurement part program in a manner that is easy to understand even if the user is not accustomed to the symbols and grammar. Aim.

[0007]

In order to achieve the above object, the present invention provides a method for displaying a measurement part program for measuring a surface property of an object to be measured, comprising: an input step of inputting a measurement part program; An analysis step of analyzing the syntax of the measurement part program; a conversion step of converting individual instructions of the measurement part program into natural language instructions; and converting the instructions into the natural language instructions based on the analysis result in the analysis step. A display step of displaying the measured part program. As a result, the contents of the measurement part program are displayed in a natural language, so that the user can easily understand the symbols and grammar of the measurement part program even if they are not familiar with them.

In the method for displaying a measurement part program, the analysis step includes a development step for developing the contents of the measurement part program, a subroutine indentation step for indenting a subroutine part in a development result in the development step, It is characterized by having. As a result, the subroutine is displayed indented, so that the nesting relationship of the subroutines can be easily understood.

Further, in this method of displaying a measurement part program, the subroutine indentation step is characterized in that contents of a subroutine called after the second time are deleted from the expansion result. Thus, when the same subroutine is called at a different location, 1
The subroutine contents are expanded and displayed at the call location for the first time, and only the subroutine name is displayed for the second and subsequent times. Therefore, even if the instruction is expanded in a natural language, the redundancy on the display can be eliminated.

In the method of displaying a measurement part program, the analyzing step further determines whether each command of the expanded result is a main measurement command or an auxiliary command, and the command determined as the auxiliary command is: An auxiliary instruction indentation step for indenting the immediately preceding main instruction is provided. As a result, auxiliary commands such as movement control and lighting control are distinguished from the main measurement commands mainly for measurement and the like, and the auxiliary commands are displayed indented with respect to the main measurement commands. Becomes even easier to understand.

Further, in the method of displaying a measurement part program, the conversion step corresponds to a figure conversion step of converting individual instructions of the measurement part program into corresponding symbolic figures, and corresponds to individual instructions of the measurement part program. A character string conversion step of converting the character string to

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a flowchart illustrating a method for displaying a measurement part program according to an embodiment of the present invention.

In FIG. 1, the process starts at S10. In the input step of S20, a measurement part program created by a CAD system or the like is input.
Each instruction line of the input measurement part program includes S3
In the serial number assigning step of 0, a series of line numbers are assigned, and an area for storing the natural language program is secured. In this state, the storage area of the natural language program is empty.

Next, in a development step of S40, a main routine (a main program for calling a subroutine) in the measurement part program is analyzed for each instruction, and the instruction is expanded and copied to a natural language program area together with a line number. I do. FIG. 2 is a flowchart showing the details. First, expansion processing is started in S40, and in the instruction analysis step of S41, after the instruction to be analyzed is copied (expanded copy) to the natural language program area together with the line number in the area next to the instruction storage area copied last time. Is parsed. Next, in S42, it is determined whether or not the instruction is a branch instruction such as a subroutine call instruction or a jump instruction. If the instruction is a branch instruction, a search is made in the measurement part program in a branch destination search step in S43. , The call destination and the jump destination are detected, and the instruction analysis is continued in the instruction analysis step of S41 for the instruction of the detected destination.

If it is determined in S42 that the instruction is not a branch instruction, it is determined in S44 whether the instruction is a return instruction from a subroutine. If it is determined that the instruction is a return instruction, a return destination is searched for and detected in a return destination search step of S45. Specifically, the sequence number N is acquired by tracing each instruction copied to the natural language program area to the subroutine call instruction. Next, if an instruction of the measurement part program whose serial number is N + 1 is searched, the instruction is a target to be analyzed next. In FIG. 2, after the return destination is searched in this way, the process returns to the instruction analysis step of S41, and the instruction analysis is continued.

If it is determined in S44 that the received instruction is not a return instruction, it is determined in S46 whether the received instruction is an end instruction for ending the main routine. If the instruction is not the end instruction, the process returns to the instruction analysis step of S41, and the instruction analysis is continued in the same manner. If it is an end instruction,
In S47, the expansion processing ends. In this way,
In the natural language program area, as a result of a call or a jump, an expanded sequence of measurement part program instructions is created.

Next, in the subroutine indentation step of S50, the nested structure of the instruction sequence of the measurement part program in the natural language program area is analyzed from the top. As a result of this analysis, the instructions in the subroutine are subjected to one-step indentation with respect to the instructions in the main routine. However, the contents of the subroutine where the same subroutine is called the second and subsequent times are deleted from the instruction sequence of the measurement part program in the natural language program area, and only the subroutine call instruction including the subroutine name is left. Indentation is similarly performed when a subroutine is further called within the subroutine.
In this case, two-step indentation is performed for the main routine. However, indentation processing is not performed on instructions following the jump destination of the jump instruction.

Next, in the auxiliary command indentation step of S60, individual instructions of the measurement part program developed in the natural language program area are main measurement instructions such as point measurement and line measurement, or movement control and lighting control. The command determined to be the auxiliary command is further indented from the immediately preceding main measurement command.
In this way, the analysis step is constituted by the steps from the expansion step of S40 to the indentation step of the auxiliary command of S60.

Next, in the figure conversion step of S70, each instruction of the measurement part program developed in the natural language program area is converted into a corresponding symbol figure (so-called icon). Further, in the character string conversion step of S80, the individual commands are converted into corresponding character strings. These icons and character strings are stored in addition to individual instruction lines of the expanded measurement part program.
In this way, the instruction sequence of the measurement part program developed in the natural language program area is from S90 to S110.
Is displayed on the CRT screen as shown in the natural language program display window 1 in FIG.

First, in the indentation hierarchy display step of S90, a nested structure of indentation, which is a skeleton of program display, is displayed by a plurality of vertical lines. In the right window of FIG. 3, this indentation structure is indicated by three vertical lines, and the leftmost vertical line is the first level,
The instructions of the main routine are displayed by being connected to the leftmost line. The middle vertical line on the right side is the level of the second stage, and among the instructions constituting the subroutine, the main measurement instruction is displayed in combination with the middle vertical line. The rightmost vertical line is connected to an instruction to be indented one more step. For example, an auxiliary instruction in a subroutine is connected here.

Next, in the graphic display step of S100,
The icon converted in the graphic conversion step of S70 is displayed so as to be connected to the vertical line according to the indentation level. Further, in the character string display step of S110, the character string converted in the character string conversion step of S80 is displayed in a form according to the icon. In this way, the measurement part program is displayed in the form of a natural language.

On the other hand, in the measurement part program display step of S120, the program (program before being converted into natural language) input in the input step of S20 is converted into the measurement part program display window 2 of FIG.
To be displayed. However, when it is not necessary, it is possible to select not to display the measurement part program and not to display the measurement part program display window 2.

In the display selection step of S130, one or a plurality of instructions are selected for the natural language program (right window in FIG. 3). In particular,
Click and select the instruction you want to select with the mouse or the like. As a result, the selected natural language program instruction is highlighted. At this time, if both the measurement part program and the natural language program are displayed at the same time, in the selection corresponding instruction display step of S140,
The measurement part program corresponding to the selected natural language program is highlighted. Specifically, a search is made for a measurement part program having a serial number that matches the serial number of the instruction selected for display in the natural language program display window 1, and as a result, the searched instruction is displayed in the measurement part program display window 2. , Highlighting is performed. FIG. 3 or FIG. 4 shows the state highlighted in this manner.

In the edit selection step of S150,
The command of the natural language program to be edited is selected in the same manner as in the display selection step of S130. At this time, S130
The difference between the selection methods of S150 and S150 is that the selection is made by a single click of the mouse in the display selection step of S130, but the selection is made by a double click of the mouse in the edit selection step of S150. The result of the selection is highlighted as shown in the right window of FIG.

When an instruction of the natural language program is selected in the edit selection step of S150, the edit window 3 is displayed in the edit step of S160.
(See FIG. 5) In the editing window 3, various arguments (instruction execution conditions) of the instruction selected and edited are displayed. Therefore, necessary arguments are edited in the editing window 3, and an "OK" button is clicked. By clicking on with a mouse, various arguments of the measurement part program can be edited.

More specifically, a search is made for a measurement part program having a serial number that matches the serial number of the instruction selected and edited in the natural language program display window 1. As a result, the arguments of the searched instruction are edited in the edit window 3. To be displayed. The edit window 3 is displayed in various display formats according to the type of the argument, and these can be selected by a selection tag. In the editing window 3 in FIG. 5, selection is possible by "position", "edge", "scanning", "detection method", and "filter". When the argument is corrected in the editing window 3, the argument of the instruction of the corresponding measurement part program is rewritten.

As a result of the editing selection in S150, the instruction in the corresponding measurement part program window is also changed in S14.
Highlighting is performed in the same manner as in the selection corresponding instruction display step of 0. In this embodiment, various arguments accompanying the measurement part program are not displayed in the display of the natural language program, but it is also possible to select to display the arguments in the natural language program as needed.

In S170, it is determined whether or not to end the series of processes for displaying a natural language program. If the process is not to be ended, the processes in steps S120 to S160 are repeated. To end the process,
When the natural language program display window 1 and the measurement part program display window 2 are deleted, and the arguments are rewritten in the editing step of S160,
The serial number assigned in S30 is deleted from the updated measurement part program, and stored and stored in the storage area. After that, in S180, all the processing ends.

Although the present invention has been described with reference to the preferred embodiments, the present invention is not limited to these embodiments, and can be modified without departing from the spirit of the present invention. For example, in the expansion step of S40, all the measurement part programs are expanded according to the execution order, and thereafter, from the subroutine indentation processing of S50 to the character string display processing of S110, the measurement is executed instead. From the subroutine indentation processing to the character string display processing can be executed for each instruction while developing the part program. By doing so, the results are displayed one by one according to the natural language conversion, so that the operator can easily grasp the conversion status.

In the graphic conversion step of S70,
Various figures (icons) may be stored separately, and the stored icons may be separately and freely edited by the operator. Further, in this graphic conversion, instead of embedding the graphic itself in the natural language program, an icon number registered separately is embedded, and in the graphic display step of S100, an actual icon image is searched from the icon number, Thereby, a natural language program display may be performed. In this way, a uniform icon display independent of the model of the measuring instrument or the like can be displayed, so that the operator can more easily understand the contents of the measurement part program.

Further, in the character string conversion step of S80, various character strings may be separately stored, and the stored character strings may be separately and freely edited by the operator. Further, in this character string conversion, instead of embedding the character string itself in the natural language program, a character string number registered separately is embedded, and in the character string display step of S110, the actual character string May be searched, and thereby a natural language program display may be performed. In this way, natural language display in an arbitrary language such as the native language can be performed, so that the operator can more easily understand the contents of the measurement part program.

In the subroutine indentation step of S50, the contents of the subroutine where the same subroutine is called from the second time onward may not be deleted from the instruction sequence of the measurement part program in the natural language program area.

Further, in displaying a natural language program,
A compression / expansion mark is provided at the first line of the instruction that follows the instruction to be indented.
The compression display and the expansion display may be alternately displayed. For example, in the display of the natural language program of FIG. 3, a negative sign surrounded by a square is displayed so as to divide a vertical line indicating an indentation structure. Indicates that the indentation command to be displayed is expanded and displayed on the screen. When the negative sign surrounded by the square is clicked with the mouse, a sign is displayed surrounded by the square, and the indentation instruction depending on the following is omitted on the screen, and the entire display amount is compressed. In this way, for example, the contents of the subroutine can be freely switched between expanded / compressed display, so that the operator can easily understand the entire program.

In the developing step of S40, an error check of the measurement part program structure may be performed. For example, when a return instruction is detected during main routine development or an end instruction is detected during subroutine development, an error message may be displayed and the processing may be stopped or interrupted. Further, the nested structure of the program is distinguished by indentation and is displayed by a vertical line. Alternatively, the nested structure may be displayed by color. For example, the first stage instruction may be displayed in black, and the second stage (contents of the first subroutine) may be displayed in blue. This makes it easier to discriminate, and prevents the need for a large display area due to a large indentation when the nested structure has multiple stages.

A natural language program display window 1
And the measurement part program display window 2 need not necessarily be displayed on the same display device, but may be displayed individually on different display devices. Further, the display of the measurement part program display window 2 may be omitted by displaying each instruction of the measurement part program together with the end or the head of the corresponding natural language program. They are,
An optimum display mode may be appropriately selected depending on the size of the display device to be used.

[0040]

According to the present invention, icons and natural language can be displayed even if the user is not familiar with the symbols and grammar of the measurement part program, so that the contents of the measurement part program can be easily understood. In other words, it is possible to prevent a measurement error of the object to be measured.
