Abstract

PROBLEM TO BE SOLVED: To improve the throughput of continuous working at a low cost. SOLUTION: Each of processing A1 to A3 measures the shape of a target, executes data processing and works a work in each processing. At the end of processing occupation time Ti of the processing A1, the working of the work is started and the measurement processing, data processing, etc., (processing A2) of a succeeding target are started. Consequently the processing occupation time Ti of the processing A2 is advanced in parallel with the working occupation time To of the processing A1. Since the working occupation time Ti of the processing A1 has been ended before the end of the processing occupation time Ti of the processing A2, the working of the work in the processing A2 can be instantaneously started by using the same working machine as that used for working the work in the processing A1 and the throughput can be improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS <1. Principle of the Invention> First, the principle of the present invention will be described. FIG. 1 is a conceptual diagram of the principle of realizing an improvement in throughput during continuous processing in the present invention. In FIG. 1, a broken line indicates a processing occupation time Ti required when generating processing data by performing measurement processing, data processing, and the like of a shape of an object, and a solid line processes a workpiece based on the processing data. Shows the machining occupation time To required for the above. Further, FIGS. 1A to 1C show a case where workpieces of workpieces for different objects are continuously generated.

In FIG. 1A, when the relationship between the processing occupation time Ti and the processing occupation time To is “Ti ≧ To”,
That is, the case where the processing occupation time To is shorter or equal to the processing occupation time Ti is shown.

In each of the processes A1, A2, and A3, the shape of the object is measured and data processing is performed, and a work is processed in each process. Then, at the time when the processing occupation time Ti in the processing A1 ends, the processing of the work is started, and the shape measurement processing, data processing, and the like (processing A2) of the subsequent target object are started. As a result, the processing occupation time Ti for the processing A2 advances in parallel with the processing occupation time To for the processing A1.
Since the processing occupation time To for the processing A1 has ended before the processing occupation time Ti for the processing A2 has ended, the processing A2 is processed by using the same processing machine that has processed the workpiece in the processing A1. Processing of the workpiece can be started immediately.

The processing occupation time T in the processing A2
At the time when i is finished, the processing of the workpiece is started, and the shape measurement processing, data processing, and the like (processing A3) for the subsequent target object are started.

Therefore, in the case of FIG. 1A, the processing system includes one modeling system for generating processing data by performing measurement processing and data processing of the shape of the object, and one processing system. The processing occupation time Ti and the processing occupation time T are configured such that the measurement of a subsequent object is started immediately after the modeling system sends the processing data to the processing machine.
o can proceed in parallel. For this reason, compared to the case where the subsequent object is measured after the end of the processing of the work as in the related art, efficient continuous processing is performed by the time in which the processing occupation time Ti and the processing occupation time To overlap. It is realized and the throughput is improved.

Next, in FIG. 1B, the processing occupation time Ti
And the relationship between the processing occupation time To and “To> Ti ≧ (To
/ 2) ".

In each of the processes B1, B2, B3, and B4, the shape of the object is measured and data processing is performed, and a work is processed in each process. And processing B1
When the processing occupation time Ti ends in, processing of the workpiece is started, and at the same time, shape measurement processing, data processing, and the like (processing B2) for the subsequent target object are started.
As a result, the processing occupation time Ti for the processing B2 advances in parallel with the processing occupation time To for the processing B1. When the processing occupation time Ti in the processing B2 ends, the shape measurement processing, data processing, and the like for the subsequent target object (processing B3) are started.

As described above, the processing occupation time Ti and the processing occupation time To are advanced in parallel, thereby enabling efficient processing and improving throughput.

Here, in order to maximize the throughput, it is preferable to immediately start machining the work when the processing occupation time Ti for the process B2 has expired. However, at that time, since the processing of the work in the process B1 has not been completed, the processing system is configured to include two processing machines, and the processing of the work in the processes B1 and B3 is performed by the first processing machine. , Processing B2
By processing the workpiece in B4 and B4 by the second processing machine, it is possible to maximize the throughput.

Next, in FIG. 1C, the processing occupation time Ti
And the relationship between the machining occupation time To and “(To / 2)> Ti”
≧ (To / 3) ”.

In each of the processes C1, C2, C3, and C4, the shape of the object is measured and data processing is performed, and a work is processed in each process. And processing C1
At the point in time when the processing occupation time Ti ends, the work processing is started, and at the same time, the shape measurement processing, data processing, and the like (processing C2) for the subsequent target object are started.
Therefore, the processing occupation time Ti for the processing C2 advances in parallel with the processing occupation time To for the processing C1. When the processing occupation time Ti in the processing C2 ends, the shape measurement processing, data processing, and the like (processing C3) for the subsequent target object are started.

In this case as well, the processing occupation time Ti and the processing occupation time To are advanced in parallel, thereby enabling efficient processing and improving the throughput.

When the throughput is to be maximized, it is preferable to immediately start machining the work when the processing occupation time Ti for the processes C2 and C3 is completed. However, at those times, since the processing of the workpiece in the process C1 has not been completed, the processing system is configured to include three processing machines, and the processing of the workpiece in the processes C1 and C4 is performed by the first processing machine. By performing the processing of the work in the processing C2 by the second processing machine and the processing of the work in the processing C3 by the third processing machine, the throughput can be improved to the maximum.

In general terms, the relationship between the processing occupation time Ti and the processing occupation time To is represented by "(To / (n-1))".
> Ti ≧ (To / n) ”, it is possible to maximize the throughput by constructing a processing system including n processing machines for one modeling system. Here, n is a natural number.

As described above, the present invention is based on the principle that data processing and the like and work processing are performed in parallel.
Thereby, the throughput is improved. Then, by configuring a processing system including a plurality of processing machines according to the relationship between the processing occupation time Ti and the processing occupation time To, the throughput can be improved to the maximum.

Hereinafter, as such a processing system, a processed product expressing the portrait of the person on the surface of the work is measured by measuring the shape of the head of the user's human body and cutting one side of the coin-shaped work. The detailed configuration of the generated three-dimensional model creation system will be described as an example.

<2. First Embodiment> First, a first embodiment will be described.

<2-1. Configuration of 3D model creation system>
FIG. 2 is a functional block diagram of the three-dimensional model creation system 1. The three-dimensional model creation system 1 measures the shape of the head of a human body, processes the obtained data to generate processing data necessary for cutting a workpiece, and a modeling system 10 for processing the workpiece. It is composed of a plurality of processing machines 21, 22, 23, 24 provided.

The modeling system 10 includes a photographing system 30, a data processing device 40, a display device 16 such as a CRT and a liquid crystal display, a storage device 43 such as a semiconductor memory and a magnetic disk, and an operation input device 44 such as a keyboard and a mouse. It is composed.

The photographing system 30 has a function of measuring the appearance (particularly, the shape of the head including the face) of the user who is the original object, and converting it into digital data (ie, converting it into data). A three-dimensional measurement device 34 that converts the shape information into data by the light projection method and outputs a three-dimensional distance image DS that is so-called three-dimensional shape data, and outputs a two-dimensional two-dimensional color image DC by converting the color information into data. 2
A three-dimensional imaging device 36 and a controller 38 are provided.

Here, the three-dimensional distance image DS is image data given as coordinate values in the XYZ rectangular coordinate system, and is measured from the measurement reference point in the three-dimensional measurement device 34 to the measurement point of the object (human head). It gives the distance information to. The three-dimensional measuring device 34 is a device that irradiates an object with illumination light and receives the reflected light to obtain information on the distance to the measurement point. However, when the reflected light cannot be received, measurement data is obtained. I can't. Therefore, the three-dimensional distance image DS also includes information of a valid flag indicating whether measurement data has been obtained.

On the other hand, the two-dimensional color image DC is two-dimensional image data composed of three primary color data of each pixel, that is, R (red), G (green), and B (blue).
For example, when the imaging system 30 is configured using the three-dimensional camera disclosed in Japanese Patent Application Laid-Open No. 9-145319, three-dimensional measurement and two-dimensional imaging can be performed from the same viewpoint, It is possible to extremely easily associate the DS with the two-dimensional color image DC.

In this embodiment, a two-dimensional color image D
C and the three-dimensional distance image DS are configured from pixel data of the same number of pixels, and pixels indicating the same index (coordinate value) are associated with each other. For this reason, when a region or a pixel is specified in one image, it is possible to specify a corresponding region or pixel in the other image.

Even when the three-dimensional measurement and the two-dimensional photographing are performed from different viewpoints, the viewpoint information is added to the three-dimensional distance image DS and the two-dimensional color image DC, respectively. Since the relative relationship between the coordinates of the result and the two-dimensional photographing result is known, the three-dimensional distance image D
The association with S and the two-dimensional color image DC can be performed without any trouble. The three-dimensional distance image DS and the two-dimensional color image DC are input to the data processing device 40.

As the three-dimensional measurement method, another method may be used instead of the slit light projection method.

The data processing device 40 has a three-dimensional distance image D
By taking in the S and the two-dimensional color image DC and performing various data processing such as image processing, each of the processing machines 21 to 21 is processed.
At 24, processing data necessary for processing a work is generated and stored in the storage device 43 with a predetermined file name.

A controller 42 is provided inside the data processing device 40. The controller 42
It is connected to a controller 38 in the photographing system 30, and receives control signals for photographing a color image and measuring a three-dimensional shape in the photographing system 30. Further, the controller 42 is connected to the operation input device 44 and the display device 16, performs an operation according to the input from the operation input device 44, and changes the display content on the display device 16.
Further, the controller 42 includes a plurality of processing machines 21 to 24.
Are connected so as to be able to communicate with each other.
4 by sending a command to each processing machine 2.
It is configured to instruct a machining operation in each of the processing machines 1 to 24 and to monitor a state of each of the processing machines 21 to 24.
That is, the controller 42 of the data processing device 40
It is configured to perform overall control and management of the three-dimensional model creation system 1.

Each of the processing machines 21 to 24 has a storage device 171 for storing characteristic data of the processing machine, and cuts a block-shaped or coin-shaped work formed of a material such as resin or metal. A processing device 172 for processing, a display device 173 for displaying a two-dimensional color image being processed by the processing machine and a state of the processing machine, supply of a work from a work mounting position to a processing position, and to an outlet of a processed product. Feeder 174 for transporting the material, the controller 1 for controlling each device inside the processing machine in response to a command from the controller 42 of the modeling system 10 and returning the status to the controller 42 of the modeling system 10
76, and an external output terminal 177. The processing device 172 accumulates a tool such as an end mill used for cutting the work, a sensor for detecting the origin position of the tool, and the like, and chips (dust) generated when the work is cut. And the like are provided, but these are not shown.

In the three-dimensional model creation system 1 having the above configuration, a plurality of processing machines 21 to 24 are connected to one modeling system 10. The controller 42 of the modeling system 10 transmits various commands to each of the processing machines 21 to 24 so that
To 24 are controlled.

Then, when starting the processing operation of the workpiece, the controller 42 transmits a command for starting the processing operation to the selected one of the processing machines 21 to 24. This command includes the modeling system 1
0 describes information relating to the file name of the processing data stored in the storage device 43 of No. 0. The processing data includes the processing device 172 and the material supply device 1 in each processing machine.
An operation sequence such as 74 is described, and by performing a processing operation based on this operation sequence, a processed product in which a target object is inlaid on the workpiece can be obtained.

In the processing machine that has received the command, the controller 176 returns one of the statuses of command acceptance, command error, and command rejection to the modeling system 10. The command acceptance is a status signal indicating that the command is normally received and an operation based on the content of the command is immediately executed. The command error is a status signal indicating that the received command is abnormal, for example, when the command content is not defined in the received command. Further, the command rejection is a status signal for indicating that the processing machine that has received the command cannot immediately execute the content of the command.

Then, the controller 176 of the processing machine that has transmitted the command acceptance accesses the storage device 43 in the modeling system 10, acquires the processing data of the file name specified by the command, and describes the described operation sequence. The processing operation of the work is started on the basis of.

When the operation indicated in the operation sequence is completed in the processing machine, the controller 176 transmits to the modeling system 10 an end status indicating that the operation corresponding to the command has been completed. The end status includes sensor information of various sensors attached to the processing machine, an operation end state, an error code, and the like. Therefore, the controller 42 of the modeling system 10
By analyzing the received end status, it is possible to determine whether the operation of the transmitted command content has been completed normally or abnormally, and to determine whether each processing machine 21
To 24 can be grasped.

In addition to the command for starting the machining operation, the controller 42 of the modeling system 10 transmits a command for transmitting or updating the characteristic data stored in the storage device 171 of each of the processing machines 21 to 24. I do. The details of the characteristic data will be described later.

Further, the controller 42 of the modeling system 10 periodically transmits a status return request command for returning only the end status to each of the processing machines 21 to 24, so that the processing of each of the processing machines 21 to 24 is performed. It is configured to periodically monitor the status.

Therefore, in the three-dimensional model creation system 1, the modeling system 10 is provided with the respective processing machines 21 to 24.
It only manages the state of each of the processing machines 21 to 24 by transmitting a command and receiving the status, and the operation control when processing the work in each of the processing machines 21 to 24 is performed by the controller 176 in each of the processing machines. It is configured to be up to you. In other words, when each of the processing machines 21 to 24 receives a command for starting a machining operation from the controller 42 of the modeling system 10, the machining operation of the workpiece is started without imposing a load on the modeling system 10.

Therefore, the modeling system 10 is responsible for measuring the object and generating the processing data in a series of operations such as measurement of the object, generation of processing data, and processing of the workpiece in the three-dimensional model creation system 1. The processing of the work can be realized so that the plurality of processing machines 21 to 24 are in charge.

When the controller 42 of the modeling system 10 sends a command for starting machining to each of the processing machines 21 to 24, the controller 42 sends a command to a subsequent person (object) in synchronization with the command sending. The next measurement operation and the data processing device 40 in all the photographing systems 30
The next data processing in is permitted. Here, the term “synchronization” means that the synchronization is performed when a command is transmitted, and includes a case where the command is transmitted simultaneously. By permitting the measurement operation and the data processing synchronized with the command transmission, the work processing and the next measurement operation and the data processing can be performed in parallel, and the pipeline as shown in FIG. Processing can be performed. As a result, the throughput is improved.

In FIG. 2, a plurality of processing machines 21 to 24 are shown.
Shows a configuration example connected to the modeling system 10. However, even when the number of processing machines is one, measurement processing and data processing in the modeling system 10 and processing in the processing machines can be performed in parallel. So you can
As a matter of course, the throughput can be improved as compared with the case where the next measurement operation is started after the processing is completed as in the related art.

As described above, considering the relationship between the processing occupation time Ti in the modeling system 10 and the processing occupation time To in the processing machine, a plurality of processing machines capable of maximizing the throughput are provided. If connected, the most efficient 3D model creation system 1
Is constructed.

In each of the processing machines 21 to 24, an external output terminal 177 is provided, and the external output terminal 177 is turned ON / OFF based on the operation sequence defined in the processing data acquired from the storage device 43. It is configured so that it can be turned off. For example, if a lamp is connected to the external output terminal 177, the lamp can be turned on and off based on the operation sequence defined in the processing data.

Therefore, by adding a control code for turning on / off the external output to the operation sequence defined in the processing data, it is possible to make a user or the like specify a processing machine to start the processing operation. it can. As a result, the user or the like can easily specify which of the plurality of processing machines 21 to 24 the work should be attached to.

<2-2. Detailed Operation of Modeling System 10> Next, the detailed operation of the modeling system 10 will be described. 3 to 5 are flowcharts showing the operation of the modeling system 10.

First, as shown in FIG. 3, when power is turned on to the three-dimensional model creation system 1, the process proceeds to step S1, and
The controller 42 of the modeling system 10 performs necessary preparations for appropriately operating each of the processing machines 21 to 24. Specifically, the controller 42 includes the processing device 172
In addition, a command for performing an initial operation such as a home return operation of the material supply device 174 is sequentially transmitted to each of the processing machines 21 to 24, and each of the processing machines 21 to 24 is prepared for operation. .

When the controller 42 receives a status indicating that the preparation operation has not been completed normally, the controller 42 displays the identification name of the processing machine, the operation name in which an error has occurred, and the like.
6 to notify the user or the like of the contents. Also,
The controller 42 excludes the processing machine for which the preparatory operation has not been completed normally from a target to which a command for starting the processing operation is transmitted. Thereby, even if there is a processing machine for which the preparation operation has not been completed normally, the three-dimensional model creation system 1 can be made operable.

Subsequently, the process proceeds to step S2, where the controller 42 of the modeling system 10 diagnoses the state of each of the connected processing machines 21 to 24. This diagnosis is a kind of monitoring operation by the modeling system 10, and is performed by acquiring characteristic data stored in the storage device 171 of each of the processing machines 21 to 24 and analyzing the contents.

The characteristic data includes tool consumption data,
It contains four types of data: chip volume data, processing machine wear data, processing machine model / identification name data.

The data for tool consumption is stored in each of the processing machines 21 to 24.
Data indicating the degree of wear of tools such as end mills provided in the processing device 172 of FIG. In general, the cutting edge of a tool is consumed when cutting a workpiece. As the wear of the cutting edge progresses, the surface properties of the processed product become rough, and in the worst case, the tool is damaged. Therefore, by managing the degree of tool wear with tool wear data,
An appropriate tool replacement time is notified to the user and the like. Specifically, a calculation is performed to increase the value indicating the degree of tool consumption according to the number of workpieces processed by the processing machine, and the degree of tool consumption is managed based on whether the value exceeds a predetermined threshold. I have to. However, it may be managed by the accumulated value of the cutting distance or the like.

Since the degree of wear of the tool varies depending on the material of the work, it is more preferable to set the weighting factor according to the material of the work to manage the degree of wear of the tool. For example, if the work material is plastic (ABS)
In the case of, the weighting factor is 1, and in the case of brass, the weighting factor is 5
Then, the above value is calculated.

The chip volume data is data indicating the amount of chips (dust) accumulated in the chip container provided in the processing device 172. As described above, a chip container is provided in the processing device 172, and maintenance for discarding chips before the chip container overflows is required. Therefore, by managing the amount of chips based on the chip volume data, an appropriate time of chip disposal is notified.
Specifically, a calculation is performed to increase the value indicating the amount of chips in accordance with the number of workpieces processed by the processing machine, and the disposal time of the chips is managed based on whether the value exceeds a predetermined threshold. I am trying to do it. However, the amount may be controlled by the amount of cutting by a tool, and in this case, the amount of chips can be controlled more accurately.

The data for processing machine consumption is stored in the material supply device 17.
4 and data indicating the degree of wear of movable parts other than tools in the processing apparatus 172. The movable parts other than the tools are also consumed by the processing operation in the processing machine, and thus require maintenance. Therefore, an appropriate maintenance time is notified by managing the degree of wear of these movable parts by the processing machine wear data. Specifically, a calculation is performed to increase the value indicating the amount of chips in accordance with the number of workpieces processed by the processing machine, and the maintenance time is managed based on whether the value exceeds a predetermined threshold. ing. However, it may be managed by the accumulated value of the cutting distance or the like, or the weighting coefficient may be different according to the material of the work like the data for tool consumption.

The processing machine model / identification name data is data for identifying a processing machine model and an individual. The controller 42 of the modeling system 10 holds a control code conversion correspondence table corresponding to the model of the processing machine, and the controller 42 specifies the model of each processing machine by acquiring the processing machine model / identification name data. Then, a control code corresponding to the model is transmitted as a command. Therefore, the processing machines 21 to 21 in the three-dimensional model creation system 1
Even when the 24 models are different, a command of a control code corresponding to each model can be transmitted, and the degree of freedom in combining the modeling system 10 and the processing machine increases.

The above characteristic data is stored in the controller 4.
2 can be obtained, and the state of each of the processing machines 21 to 24 can be diagnosed by performing arithmetic processing and analysis processing. Then, as a result of the analysis, when the tool is worn out or a chip disposal maintenance is required, the controller 42 displays the fact on the display device 16 of the modeling system 10.

FIG. 6 is a diagram showing an example of a screen displayed on the display device 16. The screen of the display device 16 is provided with a main display area RA and a processing machine state display area RB. The main display area RA includes an image frame display area RA1 and a guidance display area RA2. On the other hand, in the processing machine status display area RB, status display columns RB1, RB2, RB3, and RB4 for each processing machine corresponding to each of the processing machines 21 to 24 are provided, and below each of the status display columns RB1 to RB4. Displays an error code display field 211, a tool indicator 212 for warning of tool consumption, and a chip indicator 213 for warning of chip disposal time.

The tool indicator 212 and the chip indicator 213 are displayed in blue at the time of normal operation, are displayed in yellow when the warning level is 1, and are displayed in red when the warning level is 2. The warning level 1 and the warning level 2 are for giving different stepwise warnings according to the wear state of the tool or the amount of the chips, and the warning level 2 is a more severe warning.

If the diagnosis based on the characteristic data reveals that an error has occurred in any one of the processing machines, the controller 42 identifies the processing machine from the identification name or the like and identifies the corresponding processing machine. Status display columns RB1 to RB4
Is changed, and the error code is displayed in the error code display field 211. With this display,
Appropriate maintenance can be performed promptly when an error occurs.

The controller 4 of the modeling system 10
2 receives the status from one of the plurality of connected processing machines 21 to 24, calculates the characteristic data,
The analysis is performed, and if an error has occurred, the content is displayed as described above, and the calculation result is written to the storage device 171 of the processing machine from which the characteristic data is obtained. In response, a command for writing characteristic data is transmitted. Then, in response to this command, the controller 176 of the processing machine updates the characteristic data of its own storage device 171. By such processing, even if the processing machine is disconnected from the modeling system 10 due to, for example, a failure or maintenance, the latest characteristic data is recorded in the storage device 171 and appropriate maintenance can be performed. become.

Next, proceeding to step S3, the modeling system 10 measures the head of the human body and
An input / output process for transmitting a processing command to one of the printers 24 to 24 is performed. In this input / output processing, three processings of a main processing S31, a communication control processing S32, and a state display control processing S33 are performed, and the input / output processing (step S3) ) Is advanced.

In the main process S31, the measurement of the human head,
That is, processing data is created from input of data, and a processing machine that performs processing of a workpiece is selected based on the processing data. Note that the main process S31 is a process that is repeatedly performed while the three-dimensional model creation system 1 is constantly operating, and the main process S31 does not end unless a predetermined end operation is performed. Therefore, for example, when performing continuous machining of a workpiece, the main process S31 is repeatedly performed. This main processing S
Details of 31 will be described later.

In the communication control processing S32, a plurality of processing machines 2
Communication such as transmission of a command and reception of a status is performed with the communication devices 1 to 24.

In the state display control process S33, the respective processing machines 21 to 21 on the display device 16 of the modeling system 10 are processed.
The display indicating whether 24 is being processed or is on standby is updated.

FIG. 7 is a diagram showing an operation sequence of three processes of the main process S31, the communication control process S32, and the status display control process S33.

As shown in FIG. 7, in the main processing S31, when the processing up to the generation of the processing data is completed, in order to transmit the processing command to one processing machine, a plurality of processing machines 21 to 24 are transmitted. A request as to whether there is a processing machine in a standby state is given to the communication control processing S32 (S311).

In the communication control processing S32, each of the processing machines 21 to 21
By periodically transmitting a status return request command for returning only the end status to the H.24, it is periodically monitored whether the status of each of the processing machines 21 to 24 is being processed or is in a standby state. (S321),
In response to the request from the main process S31, a notification of the processing machine currently on standby is issued (S322).

In the main process S31, upon receiving the notification of the processing machine on standby, a processing machine selection screen is displayed on the display device 16 of the modeling system 10 to urge the user or the like to select a processing machine (S312). . At this time, in the screen shown in FIG. 6, the processing machine currently being processed in the processing machine status display area RB has a corresponding status display field R
By displaying B1 to RB4 in characteristic colors or the like, it indicates that selection is not possible. When one processing machine is selected, the main process S31 sends a request for transmitting a processing command to the selected processing machine to the communication control process S32 (S313). When the transmission request is completed, the main process S31 starts a process for measuring the next human head (object).

The communication control processing S32 includes a main processing S31
When there is a processing command transmission request from the
Then, a command for processing is transmitted to the selected processing machine among the four using an appropriate control code (S323). And
The communication control processing S32 transmits to the state display control processing S33 that the selected processing machine is processing.

In the state display control process S33, upon receiving from the communication control process S32 that the selected processing machine is processing, the selected one of the status display columns RB1 to RB4 on the display device 16 of the modeling system 10 is selected. An indication that processing is currently being performed is displayed in a column corresponding to the processing machine.

Then, when the communication control processing S32 receives the end status from the processing machine which is being processed (S32
4), it is determined whether or not the processing has been completed normally. If the processing has been completed normally, the state display control processing S33 is notified that the processing of the workpiece has been completed.

In the state display control processing S33, when the completion of the processing of the workpiece is received from the communication control processing S32, the state display of the processing machine is updated from the processing being performed to the standby state (S332). At this time, if abnormal termination has occurred, an error code is displayed in the error code display field 211.

Further, the communication control process S32 receives the end status from the processing machine which was performing the processing (S32
4) Acquire characteristic data from the processing machine and perform processing machine diagnosis (S325). This processing machine diagnosis is performed in step S2.
When there is an abnormality, the state is transmitted to the state display control processing S33 to display the contents of the abnormality.

Here, when the state display control processing S33 displays that the selected processing machine is under processing, simply displaying “under processing” does not affect the state of the processing machine with respect to the workpiece. It is unknown whether any processing has been performed. For this reason, when each of the processing machines 21 to 24 is processing,
It is more preferable that a user or the like can grasp what kind of processing is performed by each processing machine.

Therefore, in this embodiment, when the state display control processing S33 displays that the selected processing machine is processing, the image is taken in the main processing S31 and the internal processing of the data processing apparatus 40 is performed. The two-dimensional color image DC stored in the memory is displayed in the corresponding processing machine column among the status display columns RB1 to RB4. On the other hand, when the processing machine in the state display sections RB1 to RB4 is on standby, the above-described image display is not performed.

FIG. 8 is a diagram showing a display example of such a screen. In the screen example of FIG. 8, the first processing machine (that is, the processing machine 21) is in the process of processing, and the other second to fourth processing machines (that is, the processing machines 22 to 24) are in a standby state.
Then, the processing machine 21 can easily grasp what kind of processing is being performed by the two-dimensional color image displayed in the state display section RB1.

As described above, each of the processing machines 21 to 24 is also provided with the display device 173, and the display device 173 is also configured to display a two-dimensional color image that is currently being processed. ing.

Specifically, the two-dimensional color image DC obtained in the main process S31 is held in the internal memory of the data processing device 40, and the modeling system 10
Of the storage device 43 with a predetermined file name. The storage device 43 provides an environment in which the controller 176 of each of the processing machines 21 to 24 can freely access by a network sharing function or the like. When the modeling system 10 sends a command for starting a processing operation to a specific processing machine, the processing machine stores the information in the storage device 43 by adding information on the file name of the two-dimensional color image. It is possible to acquire the two-dimensional color image DC that has been performed. Therefore, the processing machine acquires the two-dimensional color image specified by the command and displays the image on the display device 173, whereby the color image of the human head to be processed can be displayed on the processing machine side. It is possible to easily understand what kind of processing is being performed by the processing machine.

Here, the modeling system 10
Display device 16 and display device 173 of each of the processing machines 21 to 24
Although an example in which a two-dimensional color image is displayed on both of them is shown, displaying on either one also makes it easy to grasp the processing content of the processing machine.

The input / output processing in step S3 is performed as described above. Then, when the end of the repeated main process (S31) is instructed, the process exits this input / output process and proceeds to step S4.

At step S4, each of the processing machines 21 to 2 is again
The diagnosis of No. 4 is performed. The processing performed in step S4 is the same as the diagnosis processing shown in step S2. If there is an abnormality as a result of the diagnosis, the content is displayed on the display device 16 of the modeling system 10 to prompt maintenance.

Then, the process proceeds to step S5, and as a termination process, after preparing for power-off in the data processing device 40, power-off is performed.

<2-3. Details of Main Processing S31> Next, details of the above-described main processing S31 will be described. FIGS. 4 and 5 are flowcharts showing the main processing in the modeling system 10 in detail.

As shown in FIG. 4, in the main processing S31,
First, a two-dimensional image is displayed (step S10).
1). Here, a real-time two-dimensional captured image is displayed to position the human head. In the real-time two-dimensional captured image, the image frames are displayed so as to overlap each other so that only the shape of the work whose head shape such as a face is cut is visible. FIG. 9 is a diagram showing a display screen at this time. As shown in FIG. 9, an image frame 231 corresponding to the outer size of the work is displayed in the image frame display field RA1 of the main display area RA on the screen of the display device 16, and a two-dimensional captured image is displayed inside the circular window. Is displayed.

Then, the process proceeds to step S102, in which it is determined whether or not a photographing operation has been performed. If the photographing operation has been performed, a two-dimensional color image DC is photographed by the two-dimensional photographing device 36 (step S103). ). The resulting two-dimensional color image DC is transferred from the imaging system 30 of the modeling system 10 to the internal memory of the data processing device 40. At this time, the image in the image frame 231 displayed in the image frame display field RA1 shown in FIG. 9 is no longer a real-time two-dimensional captured image, and the two-dimensional color image DC obtained by the shooting operation is stored in the image frame 231. Is displayed.

Then, the three-dimensional distance image DS is measured by the three-dimensional measuring device 34 (step S104).
The three-dimensional distance image DS obtained as a result is also transferred to the internal memory of the data processing device 40 as in the case of the two-dimensional color image DC.

Next, the process proceeds to step S105, where various editing processes such as image frame position adjustment, image frame size adjustment, background region editing, skin region editing, and the like are performed. The details of this editing process are shown in the flowchart of FIG.

As shown in FIG. 5, the editing process (step S
In 105), first, a confirmation image is displayed (step S201). In the display of the confirmation image, for example, a two-dimensional binary image is created in which pixels for which the three-dimensional measurement of the three-dimensional distance image DS is normally performed are set to “white” and pixels for which the three-dimensional measurement is not performed normally are set to “black”. Then, this is displayed on the display device 16.

FIG. 10 is a diagram showing a display screen at this time. As shown in FIG. 10, a confirmation image 251 indicating whether or not the three-dimensional measurement has been normally performed is displayed in a guidance display field RA2 on the screen of the display device 16, and is displayed at a lower right position of the guidance display field RA2. Displays a re-photographing button 252 for re-photographing.

[0100] By referring to the confirmation image 251, the user can judge whether or not a part necessary for processing the work can be normally measured three-dimensionally.
When it is determined that the three-dimensional measurement has not been performed normally, the operation of pressing the re-photographing button 252 by operating the operation input device 44 such as a mouse is performed.
The processing can be returned to the display of the two-dimensional image (step S101) shown in FIG.

The display of the confirmation image (step S2)
When performing 01), it may be possible to indicate whether or not a user or the like as a subject has moved during shooting. When obtaining the three-dimensional distance image DS with the three-dimensional measuring device 34, the subject needs to be stationary for a certain period of time (for example, about 0.6 seconds) due to light scanning or the like. If the subject moves during this time, accurate three-dimensional shape measurement cannot be performed.

Therefore, it is more preferable to display an image for confirming whether or not the user is stationary at the time of photographing. Specifically, a two-dimensional color image DC
Out of the pixels forming the three-dimensional distance image DS, only the pixels where the three-dimensional measurement data exists are extracted, and the extracted pixels are not displayed while displaying an image based on the two-dimensional color image DC. By performing image display by texture mapping, such as displaying a pixel with a predetermined color,
It can be determined whether or not the dimensional distance image DS has been obtained. As another method, two-dimensional color images are photographed twice before and after three-dimensional measurement (step S104), and three-dimensional measurement is performed by displaying a difference image between the two two-dimensional color images. At this time, it can be determined whether or not the subject has moved.

Further, in generating the processing data, the modeling system 10 does not faithfully reproduce the shape of the subject, but performs a compression process in the depth direction when cutting the work. This three-dimensional measuring device 3
4 corresponds to the depth direction when the subject is three-dimensionally measured,
As a processing method at the time of performing the compression processing, there are a method of compressing all the valid three-dimensional measurement data in accordance with the cuttable depth of the work, a method of cutting off the data at a preset depth, There is.

However, when the shape of the human head is to be measured by the three-dimensional measurement device 34, the neck, shoulder, etc.
It may be input as a part of the three-dimensional distance image DS. In particular, when a profile is input, the shoulder is on the near side of the face and the neck is on the back of the face. For this reason, when the above-described compression method is adopted, the compression is performed in consideration of the distance information of the shoulder, the neck, and the like, so that the unevenness of the face portion becomes thin, and the expressiveness to the processed product is reduced. Can occur.

In order to solve this problem, the processing of steps S202 and S204 described below is performed. In these processes, the user or the like adjusts the position and size of the image frame corresponding to the size of the work to prevent the subject's shoulder or neck from entering the processing target, or to adjust the subject's shoulder or neck or the like. Dare setting is performed as a background area.

Therefore, when performing these processes,
Since it is preferable for the user to recognize information indicating the measured depth of the three-dimensional distance image DS (that is, distance information), not only the two-dimensional binary image is displayed as the confirmation image 251 in step S201, but also the measurement is performed. Preferably, the added depth information (distance information) is added. For example, when three-dimensionally measuring the human head of the user, the near side near the three-dimensional measuring device 34 is set to “red” and the far side is set to “blue”, and color information is associated with the confirmation image 251. When displayed, it becomes easy to recognize what shape is measured by the confirmation image 251.

Next, the process proceeds to step S202, where a contour cutting operation is performed. This contour cutting operation is to allow the user or the like to adjust the position of the image frame 231 and the size of the image frame 231 in the image frame display field RA1 displayed on the display device 16. FIG. 11 is a diagram showing a screen display example when this operation is performed. FIG. 11A shows a size adjustment operation, and FIG. 11B shows a position adjustment operation.

The circular window of the image frame 231 corresponds to the shape and size of the work, and the contents displayed inside the circular window are to be processed. And FIG.
As shown in (a), size adjustment buttons 231a are provided at the four corners of the image frame 231. The mouse pointer 232 is moved to any one of them, and a predetermined click operation and drag operation are performed. Thereby, the size of the image frame 231 for the two-dimensional color image can be adjusted.

As shown in FIG. 11B, the mouse pointer 232 is moved to the size adjustment button 231 of the image frame 231.
By performing a predetermined click operation and drag operation in accordance with a position other than “a”, the position of the image frame 231 with respect to the two-dimensional color image can be adjusted.

As described above, the user or the like easily adjusts the position and the size of the image frame 231 to easily grasp the state in which the shape of the human head is cut (worked state) on the work. be able to. Note that the operation of size adjustment is equivalent to inputting a reduction ratio or an enlargement ratio on a plane perpendicular to the depth direction when scaling the three-dimensional distance image DS in a later calculation process.

Next, the process proceeds to step S203, where a background area is displayed. The background region can be specified by measuring the color components of a background film (blue back) provided on the background side of the human head when inputting a two-dimensional color image. That is, by comparing the previously measured color components (R, G, B values) of the blue background with the color components (R, G, B values) of each pixel of the two-dimensional color image DC, 2
The background area can be estimated from the two-dimensional color image DC. Then, in order to make the estimated background area visible to a user or the like, a two-dimensional color image obtained by performing special processing on the estimated background area is displayed in the image frame 231.
As the special processing, for example, predetermined R, G, and B values for offset are added to and subtracted from R, G, and B values of pixels estimated to be a background area in a two-dimensional color image obtained from the imaging system 30. Is done. Such special processing is performed to indicate to the user or the like whether or not the modeling system 10 accurately recognizes the background area.

In the modeling system 10, any one of addition and subtraction of R, G, and B values for offset can be performed, and addition or subtraction can be selectively selected on the screen of the display device 16. A radio button is displayed, and the user or the like specifies one of them. However, a plurality of types of offset R, G, and B values may be prepared, and a radio button may be set for each of them, so that the offset R, G, and B values can be selected alternatively. You may be comprised so that a user etc. may directly input R, G, B value for offset.

The reason why a plurality of types of processing are prepared as special processing is that the color distribution of a subject (such as a human head) varies depending on the person.
That is, since the color distribution of the subject is indefinite, it is difficult to distinguish the region estimated as the background region from the other regions depending on the color distribution of the subject when the offset R, G, and B values are set to only one. This is because there are cases. However, if it is configured so that a plurality of types of special processing can be performed, when it is difficult to distinguish the area estimated as the background area from the other areas, the mode of the special processing is changed to another one. There is an advantage that it is possible to distinguish.

When the background area is displayed on the display device 16 in this manner, the process proceeds to step S204.

In step S204, an editing operation of the background area is performed. FIG. 12 is a diagram showing a display screen of the display device 16 at this time. As shown in FIG. 12, when the display processing of the background area in step S203 is completed, a two-dimensional color image having the background area subjected to special processing is displayed inside the image frame 231. This background area can be further added by a mouse operation of a user or the like, or can be changed from the background area to another area. A specific operation will be described. Move the mouse pointer 233 to the image frame 231.
By performing a predetermined click operation and drag operation in accordance with a position other than the middle background area, a pixel in the movement locus of the mouse pointer 233 is newly designated as a background area. Further, the mouse pointer 233 is positioned at a position in the background area in the image frame 231, and a predetermined click operation and drag operation are performed.
The pixel in the movement locus of No. 3 is designated as a region other than the background region. At this time, the region to be edited is only the two-dimensional color image displayed inside the circular window of the image frame 231, and the image frame 231 itself is not to be edited.

Note that a change button 253 for changing the size of the mouse pointer 233 is provided in the guidance display field RA2, and by selecting one of the change buttons 253, the image frame 23 is displayed.
The size of the mouse pointer 233 displayed in 1 is changed.

By specifying a part such as a neck or a shoulder as a background area when editing the background area, the above-described problem in the depth direction can be solved.

When the editing process of the background area is completed, three areas of the two-dimensional color image DC, that is, the image frame area, the background area, and the other areas can be distinguished. Then, each area is stored in an internal memory in the data processing device 40 in a state where predetermined identification data is added.

Next, the flow advances to step S205 to display a skin area. For example, a user or the like performs a predetermined mouse operation to specify a skin portion from the two-dimensional color image in the image frame 231. At this time, the part that has already been determined as the background area is excluded from the designation target.

The modeling system 10 can estimate the skin area by analyzing the color components of the designated skin portion and extracting all the pixels similar to the color components. At this time, the portion that has already been determined as the background region is excluded from the estimation target of the skin region.

Then, as in the case of step S203, a predetermined offset R and R are added to the portion of the two-dimensional color image displayed in the image frame 231 which is estimated as the skin region.
The display of the skin area is performed by adjusting the G and B values.
With this display, it is possible to easily grasp which part in the two-dimensional color image is recognized as the skin area.

Next, the flow advances to step S206 to perform an editing operation on the skin area. The operation performed here is the same as the editing operation of the background area described in step S204.
That is, by performing a predetermined mouse operation, an area other than the skin area is specified as a skin area, and a portion estimated as the skin area is specified as an area other than the skin area. However, an area already determined as a background area is not to be edited. When the editing process of the skin area is completed, four areas of the image frame area, the background area, the skin area, and the other areas can be distinguished in the two-dimensional color image DC. Then, each area is stored in an internal memory in the data processing device 40 in a state where predetermined identification data is added.

Next, the flow advances to step S207 to display other areas. For example, a user or the like performs a predetermined mouse operation to specify a part such as a hair ornament from a two-dimensional color image in the image frame 231. At this time, a part that has already been determined as a background area and a skin area is excluded from the designation target.

The modeling system 10 can estimate a region such as a hair ornament by analyzing the color components of the designated hair ornament or the like and extracting all pixels similar to the color component. At this time, a portion that has already been determined as a background region or a skin region is excluded from estimation targets for other regions.

Then, as in the case of step S203, predetermined offset R, G, and B values are assigned to portions of the two-dimensional color image displayed in the image frame 231 which are estimated to be areas such as hair ornaments. By adding or subtracting, an area such as a hair ornament is displayed. With this display, it is possible to easily grasp which part in the two-dimensional color image is recognized as an area such as a hair ornament.

Then, the flow advances to step S208 to perform an editing operation on other areas such as hair ornaments. The operation performed here is the same as the editing operation of the background area described in step S204. In other words, by performing a predetermined mouse operation, an area other than the area such as the hair ornament can be newly designated as the area such as the hair ornament, or a portion estimated as the area such as the hair ornament can be designated as the hair ornament or the like. It is specified as an area other than the area. However, an area that has already been determined as a background area or a skin area is not to be edited. When the editing process of the other areas such as the hair ornaments is completed, in the two-dimensional color image DC, five areas including an image frame area, a background area, a skin area, an area such as a hair ornament, and other areas are set. This means that the areas can be distinguished. Then, each area is stored in an internal memory in the data processing device 40 in a state where predetermined identification data is added.

When the processing up to this point is completed, the editing processing (step S105) is completed, and the process proceeds to step S106 shown in FIG.

In step S106, two-dimensional hair data is extracted. By the above-mentioned editing process (step S105), the two-dimensional color image is divided into five regions: an image frame region, a background region, a skin region, a region such as a hair ornament, and other regions. . Therefore, the areas recognized as other areas can be considered to be equivalent to the hair area. Therefore, in the extraction of the two-dimensional hair data, the pixels included in the hair region are extracted from the pixels constituting the two-dimensional color image, and a filtering process in a predetermined frequency region is performed in order to reproduce the flow shape of the hair. The normalization process is performed to generate a two-dimensional gray image of the hair region.

Next, the flow advances to step S107 to generate a three-dimensional head shape. The three-dimensional head shape is divided into a skin area, a hair area, and a hair ornament area excluding the background area in the two-dimensional color image.

It is considered that most of the skin area and the hair decoration area are included as effective measurement data in the three-dimensional distance image DS, but if they are not included as effective measurement data, other areas are considered. The shape interpolation is performed by using the effective measurement data portion of.

On the other hand, it is considered that most of the hair area is not included as effective measurement data in the three-dimensional distance image DS, and thus the shape data of the hair area is restored by calculation. That is, a three-dimensional hair shape that smoothly connects to the skin region is generated from the three-dimensional distance image DS of the skin region, and a predetermined offset is applied to the three-dimensional hair shape in order to reflect the swelling of the hair portion on the skin region. give. Then, the gray component of the two-dimensional gray image of the hair region is converted into a height component (a component in the depth direction). And 2
By superimposing the height component obtained from the three-dimensional gray image on the offset three-dimensional hair shape, three-dimensional shape data of the hair region can be obtained. Then, by applying the three-dimensional shape data to the hair region of the three-dimensional distance image DS, a complete three-dimensional shape model is obtained.

Then, the process proceeds to a step S108, where a scaling process is performed. The three-dimensional shape model generated in the three-dimensional hair shape generation process (step S107) has the same size as the human head. Therefore, in the scaling process (step S108), the three-dimensional shape model is scaled (enlarged / reduced) so as to be adapted to the size of the work.

First, planar enlargement / reduction will be described. The above-mentioned image frame 231 corresponds to the size of the work to be processed, and since the size of the work is known, the size of the three-dimensional shape model and the size of the two-dimensional color image displayed in the image frame 231. From this, the enlargement / reduction ratio can be determined. Then, by scaling the three-dimensional shape model based on the determined enlargement / reduction ratio, a model suitable for the size of the work can be generated.

On the other hand, in the depth direction, first, the same enlargement / reduction ratio as the planar enlargement / reduction ratio is set. Then, thereafter, a method of compressing / enlarging to a certain work cutting depth (depth dimension) for all the pixels of the three-dimensional shape model, and a set depth (depth dimension) of the three-dimensional shape model And two methods of compressing / expanding to a certain cutting depth of the work after cutting by the cutting can be selected.

After the scaling is performed so that the three-dimensional shape model fits the size of the work, the process proceeds to step S109, and processing data is generated from the scaled three-dimensional shape model. When the processing data is generated, a file name is given to the processing data and stored in the storage device 43.

Next, the flow advances to step S110 to select a processing machine. In this step S110, as shown in FIG. 7, the main process S31, the communication control process S32, and the state display control process S33 function, and the main process S31 obtains information of the machine that can be machined and displays it on the display device. 16
And prompt the user to select a processing machine.
Then, when a processing machine is selected, a request is made to the communication control processing S32 to send a processing command to the selected processing machine.

When the processing up to this point is completed, the main processing S31 determines whether or not there is a termination instruction from the operation input device 44 (step S111). If there is no termination instruction, the processing from step S201 is repeated. By doing so, the next human head measurement process starts. Therefore, in this case, the modeling system 10 can start the next processing before the processing of the workpieces in the processing machines 21 to 24 is completed, and the modeling system 10 and the plurality of processing machines 21 to 24 can operate in parallel. Processing has been realized.

On the other hand, if there is an end instruction in step S111, the main process S31 ends, and the process proceeds to step S4 shown in FIG.

<3. Second Embodiment> Next, a second embodiment will be described. FIG. 13 is a functional block diagram of a three-dimensional model creation system 1a according to the second embodiment. The same members as those in the three-dimensional model creation system 1 shown in FIG. 2 are denoted by the same reference numerals, and description thereof will be omitted.

The three-dimensional model creation system 1a differs from the three-dimensional model creation system 1 in the first embodiment in that the modeling system 10a and the photographing system 30a are configured as separate blocks.

The photographing system 30a includes a three-dimensional measuring device 34, a two-dimensional photographing device 36, and a controller 38 having the same configuration as in the first embodiment, and further includes a display device 31, a photographing trigger switch 32, and the like. The storage device 39 is provided.

The modeling system 10a includes a display device 16, a data processing device 40, a storage device 43, and an operation input device 44. The data processing device 40 is provided with a controller 42.

In the three-dimensional model creation system 1a, the real-time two-dimensional captured image displayed at the time of shooting is performed on the display device 31 in the shooting system 30a. Then, when a user or the like presses a shooting trigger switch 32 provided in the shooting system 30a, the input of the two-dimensional color image DC and the three-dimensional distance image DS is performed. 2 obtained in the photographing system 30a
The three-dimensional color image DC and the three-dimensional distance image DS are sequentially stored in the storage device 39 in the imaging system 30a. Therefore, the photographing system 30a performs steps S101 to S104 of the main process S31 shown in FIG.
Is performed independently of the modeling system 10a.

Further, in this embodiment, the modeling system 10a is configured to handle the processing of steps S105 to S111 of the main processing S31 shown in FIG. And the modeling system 10a
Acquires a set of two-dimensional color image DC and three-dimensional distance image DS, and performs a series of processes from editing to generation of processing data (steps S105 to S11).
When 1) is completed, a trigger signal is sent to the imaging system 30a.

The controller 38 of the photographing system 30a
Is configured to transfer the next set of two-dimensional color images DC and three-dimensional distance images DS stored in the storage device 39 to the modeling system 10a upon receiving this trigger signal.

As a result, the modeling system 10a repeats a series of processes (steps S105 to S111) from the next editing to the generation of processing data.

The operation of each of the processing machines 21 to 24 in parallel with the data processing in the modeling system 10a is the same as that described in the first embodiment.

Therefore, when the configuration of the three-dimensional model creating system 1a as in this embodiment is adopted, two mechanical units such as a modeling system and each processing machine are pipeline-processed as in the first embodiment. It is no longer, the imaging system 30a and the modeling system 1
0a and three mechanical units such as the respective processing machines 21 to 24 are pipeline processed.

That is, in the first embodiment, while performing data processing for generating processing data in the modeling system 10, it is not possible to start the next measurement operation for the following person. However, in this embodiment, even while the modeling system 10a is performing the data processing for generating the processing data, it is possible to start the next measurement operation for the following person. It becomes.

As a result, the three-dimensional model creation system 1a
More efficient processing than the contents described in the first embodiment can be performed, and even when the head shape of the customer is continuously measured, the waiting time for the measurement given to the customer is reduced. It becomes possible.

<4. Modifications> Although the embodiments of the present invention have been described above, the present invention is not limited to the contents described in each of the above embodiments.

For example, in the above embodiment, a configuration example in which a plurality of processing machines are connected to the modeling system has been described, but the number of processing machines may be one. Even in this case, by performing measurement of the target object and / or generation of the processing data during the processing of the workpiece, the modeling system and the processing machine can be processed in parallel, and the throughput is higher than that of the conventional system. Is improved.

In the above embodiment, the three-dimensional model creation system in the case where the object is a human head has been described. However, the present invention is not limited to this, and the object may be another object. Good.
