Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a spectacle frame, and a shape measuring device for measuring the shapes of a template and a demo lens (guard lens) following the shape of the spectacle frame.

[0002]

2. Description of the Related Art A spectacle lens maker receives an order from a spectacle store for a customized lens in order to provide a spectacle user with a spectacle lens that is as thin and light as possible.

As the data for manufacturing this custom lens, prescription data (for example, spherical power of a spectacle wearer,
Astigmatic power, astigmatic axis angle, interpupillary distance (PD), vertical displacement of the optical center with respect to the geometrical center (boxing center) of the eyeglass frame, and frame shape data (2 of eyeglass frame). Both dimensional shape data, frame PD (FPD), etc. are required.

Of these, the frame shape data is difficult to measure, and various methods for facilitating the measurement have been proposed and implemented. For example, a frame tracer or a digitizer dedicated to the frame shape measurement is prepared and the measurement is performed using this. As a document relating to the frame tracer, there is, for example, JP-A-61-267732.

In some cases, the spectacle lens maker classifies the frame in advance according to the shape pattern and size, and prepares the template for each classification. In this case, apply the spectacle frame to the template,
The size of which pattern was most suitable for the frame was visually determined and measured.

Various ordering data measured and digitized in this way are transmitted to an eyeglass lens maker through a telephone line from an ordering terminal installed in an ophthalmologist or an eyeglass store.

[0007]

However, the method using a frame tracer or a digitizer has a problem in terms of cost because it requires an expensive dedicated device, although the measurement accuracy is excellent. Further, a place for installing the device is also required. Therefore, it has been difficult to introduce these devices unless the store has a high order frequency of custom-ordered lenses or a large store.

In the method using the template, since the person visually makes the classification judgment, the error tends to be large unless the user is an expert. There is also a problem that the measurement takes time.

The present invention utilizes an existing ordering terminal to
It is an object of the present invention to provide a shape measuring device that is inexpensive and has good operability, does not require a dedicated installation place, and can perform measurement with necessary and sufficient accuracy (radius error is within about 2 mm). .

[0010]

The present invention has been made to achieve the above object, and in one aspect thereof, display means having a screen and an object for shape measurement are brought close to the screen. Holding means for holding in a state, designating means used for designating a position on the screen, and coordinates of a plurality of input points designated by the designating means by the designating means, and the input A shape measuring apparatus is provided, which comprises: a control unit that displays points on the screen.

The correction instruction means further comprises a storage means for storing the coordinates of the input point obtained by the control means, and a correction instruction means for receiving an instruction from the user to delete the desired input point. Receives a delete instruction,
It is preferable that the control means has a function of deleting the coordinate information of the input point instructed to be deleted from the storage means.

The control means further has a storage means for storing the coordinates of the input point obtained by the control means, and the control means obtains a complementary curve of the input point and displays the complementary curve on the screen. And output means for receiving an output instruction from the user and outputting the coordinates of the input point and / or the formula of the complementary curve stored in the storage means at the time of receiving the instruction. .
In this case, the storage means stores in advance classification information in which the shape and size of the target object are classified, and the control means compares the complementary curve with the classification information to obtain the complementary curve. Has a function to search the classification to which
The output means may output information indicating the classification discovered by the control means, instead of the coordinates of the input point and the formula of the complementary curve.

A tilt input means for inputting information for specifying the tilt of the object; and the control means for displaying the screen of the object based on the information input from the tilt input means. It is preferable to further have a function of obtaining the inclination of the object in parallel planes, and to have an output unit that receives an output instruction from the user and outputs the inclination obtained by the control unit.

[0014]

The object of shape measurement is held by the holding means in the vicinity of the display screen. Then, on the screen, the contour point of the object is designated as an input point. Then, the control means
The coordinates of the input point are obtained, and the input point is displayed on the screen. The coordinates are also stored in the storage means.

When the correction instruction means accepts the deletion instruction,
The control means erases the coordinate information of the input point instructed to be deleted from the storage means. Further, the control means obtains a complementary curve of the input point and displays the complementary curve on the screen.
Furthermore, based on the information input from the tilt input means,
The inclination of the object in a plane parallel to the screen of the object is obtained.

Upon receiving an output instruction from the user, the output means outputs the coordinates of the input point stored in the storage means and / or the equation of the complementary curve, the slope and the like.
In this case, the classification information may be output instead of the complementary curve formula or the like.

[0017]

An embodiment of the present invention will be described with reference to the drawings.

The present embodiment is characterized in that the display of the ordering terminal, the mouse and the like are used as an input device for inputting the shape of the spectacle frame.

An external view of this embodiment is shown in FIG. 1, and a hardware diagram including the internal structure is shown in FIG. Ordering terminal 10
0 is an indicator 110, a keyboard 120, a mouse 13
0, etc. are included. The user can input various prescription data using the keyboard 120 or the like. The ordering terminal 100 has a built-in (or external) modem 200 and has a function of transmitting the input ordering data to the lens maker through a telephone line.

Internally, it comprises an arithmetic control circuit 101, a graphic display circuit 102, a mouse coordinate data & switch data input circuit 103, a key data input circuit 104, a communication control circuit 105 and the like. Has been done.

The arithmetic control circuit 101 realizes various functions by storing a program in a memory not shown in the figure and executing the program. For example, detection of mouse cursor coordinates, mouse 130
The switch operation can be detected. Also, points,
Display data such as lines, cursors, curves, and characters is processed, and the display 110 is displayed through the graphic display drive circuit 102.
It has a function to control the display. Further, the arithmetic control circuit 101 of the present embodiment has a program for measuring the frame shape in the memory. Further, the measurement data is also stored in the memory. The details of the program will be described later together with the operation description.

In addition to the above configuration, the ordering terminal 100 of this embodiment has a frame 21 of eyeglasses on the display screen of the display 110.
Frame fixing device 150 for fixing 0 and the like in close proximity
Is equipped with. In FIG. 1, the frame fixing device 1
By means of 50, the left and right temples (vines) of the frame are hung on the hanging string 151. The purpose of the frame fixing device 150 is to place the spectacle frame 210 as close as possible and stably to the display 110 to create a state with a small parallax. Therefore, for example, as shown in FIG. 3, an adhesive tape 250 is used to display the template 220 and the dummy lens 2 on the display 110.
You may make it stick 30 directly. In addition,
Trace the shape, copy the shape on a transparent film,
The transparent film may be attached to the display 110.

The display screen of the display 110 is shown in FIGS.
As shown in, an input reference frame 160 and a horizontal reference line 161 are displayed as an auxiliary display for installing a spectacle frame or the like.

The input reference frame 160 is for displaying the standard of the position where the rim of the frame 210 is installed. In general, the rim shapes on the left and right of the frame are almost symmetrical, so it is sufficient to measure the shape of the right or left piece. However, it goes without saying that it is possible to input both the left and right shapes.

The horizontal reference line 161 is a horizontal reference line when the frame 210 or the like is installed on the display 110. Also when the template 220 is installed, it is installed so that the horizontal line printed on the template 220 is substantially parallel to the horizontal reference line 161. However, the frame 210 or the like is not necessarily the horizontal reference line 1
Even if it is not installed parallel to 61, by pointing two horizontal reference points 164 at the time of inputting coordinates, the inclination angle of the frame or the like can be calculated and the coordinate data of the contour points can be corrected. The horizontal reference point 164 will be described later.

The cursor 163 is for inputting coordinates of a plurality of points on a contour line such as a frame. The cursor 163 is a mouse 130 or a keyboard 12
Move according to 0 operation. In this embodiment, the cursor 163 is formed in a cross shape to improve the accuracy of position input along the contour of the frame. It should be noted that, in areas other than the shape measurement area (that is, command menus, display fields, etc., which will be described below), the cursor changes into an arrow shape, as in a normal device.

In addition to the above, the display 110 is provided with command menus 190 to 1 for inputting commands during shape measurement.
95, and display fields 197, 198, 199 for displaying measurement data and input data are displayed. The function of each command shown in the command menu will be explained together with the operation explanation.

The ordering terminal 100 can be constructed by using a commercially available personal computer.

In the claims, the "input point" means a point for inputting the shape of the measurement object ("shape point").
And a point (“horizontal reference point”) for inputting the inclination of the measurement target.

Next, the shape measuring operation and the processing operation according to this embodiment will be described with reference to the flowcharts of FIGS. 6, 7 and 8. Here, for convenience of description, the operation performed by the user and the process executed by the ordering terminal 100 will be collectively described.

Before starting the measurement, the user fixes the frame 210 and the like with the frame fixing device 150.

When the apparatus is activated, the arithmetic control circuit 101
Automatically sets the operation mode to the shape point input mode and initializes the measurement target. In order to notify this, the "shape point input" 192 of the display 110 and the display of the initially set measurement object ("frame" 190, "template" 191) are surrounded by thick lines (step 601). In this embodiment, the frame is automatically selected as the initial setting of the measurement target, but the present invention is not limited to this, and the template may be automatically selected. Alternatively, the previously selected measurement target may be initialized.

After step 601, a standby state is entered while monitoring the input from the mouse 130 (step 602).
603). In this standby state, the user can perform operations such as selection of various commands or input of shape points.

If there is any input from the user in step 603, it is first determined whether or not the motion mode at that time is the shape point input mode (step 604). As a result, if it is the shape point input mode, then it is determined what the input indicates (steps 605 to 612).

When the input is the coordinate input in the shape measuring area (that is, when the user moves the cursor 163 and inputs the contour point at the desired position of the frame 210) (step 605). ), Arithmetic control circuit 101
Receives and stores this coordinate input via the input circuit 103, and displays the input point 170a indicating the coordinate point (step 613, see FIG. 9A). Then, after this, the process returns to steps 602 and 603 to enter the standby state again. The coordinates are input by operating the switch 131 of the mouse 130. The contour point to be input may be any point on the contour line inside the rim, but in order to perform more accurate measurement with a small number of input points, the maximum value inflection point and the minimum value inflection point of the radius change should be set. It is good to specify. Actually, it is preferable to input at least about 8 to 12 points. When the user repeats the coordinate input a desired number of times, input points 170a to 170h are displayed on the display 110 along the rim inner contour line of the frame (FIG. 9 (b)). (See (c)) When the input is the selection of the command "shape point addition / deletion" 193 by the mouse 130 (step 60)
6), the arithmetic control circuit 101 calculates a curve 180 (for example, a spline curve) that smoothly connects the input points input so far, and displays this on the display 110 (step 614, see FIG. 9D). ). Then, after that, the operation mode is switched to the shape point addition / deletion mode. After that, the process returns to steps 602 and 603, and the standby state is resumed. In this standby state, the user can
It is possible to compare 0 and the actual frame to confirm the compatibility between the two. If the two do not match each other, the input data can be corrected by the processing of FIG. 7 described later.

The input is the command "horizontal reference point input" 194.
If it is selected (step 607), a curve 180 (for example, a spline curve) that smoothly connects the input points input so far is calculated, and this is displayed on the display 110 (step 616, FIG. 9 (d)). Then, after that, the coordinate input by the mouse 130 is accepted twice, and the two points input at this time are set to the horizontal reference points A and B.
(Steps 617 and 618). Further, the inclination of the straight line connecting the horizontal reference point A and the horizontal reference point B is calculated and displayed in the inclination display area 198 (step 619). As the horizontal reference points A and B, it is most reliable and preferable in terms of accuracy to specify the positions 164a and b of the roots of temples on the left and right of the frame (see FIG. 10). This operation can be omitted if the frame is placed almost completely along the horizontal reference line 161. In this case, the arithmetic control circuit 101 handles the tilt angle as 0 °. After step 619, steps 602 and 603
Then, it returns to the standby state.

When the input is the selection of the command "end" 195 (step 608), the processing of FIG. 8 described later is executed.

When the input is selection of the measurement targets 190 and 191 (step 609), the measurement target is switched and the display of the new measurement target is surrounded by a thick line (step 620). After step 620,
Returning to steps 602 and 603, the standby state is again established. It should be noted that, depending on the change or selection of the measurement target performed here, the processing content of step 802 of FIG. 8 described later differs.

When the input is the operation of the button 131 with the cursor placed in the FPD data area 197 (step 610), the input of the FPD data from the keyboard 120 is performed. Is received and stored in the arithmetic control circuit 101, and the input data is stored in the FPD data area 19
7 is displayed (step 621). After step 621, the process returns to steps 602 and 603, and the standby state is resumed.

When the input is the operation of the button 131 by placing the cursor on the rim depth data area 199b (step 611), the rim depth data from the keyboard 120 is input. The data input is received and stored in the arithmetic control circuit 101, and the input data is displayed in the rim depth data area 199b (step 622). Step 6
After 22, the process returns to steps 602 and 603, and again enters the standby state.

When the input is the operation of the button 131 with the cursor placed in the model number data area 199a (step 612), the model number data from the keyboard 120 is input.
A data input is accepted and stored in the arithmetic control circuit 101, and the input data is stored in the model number data area 199a.
(Step 623). After step 623, the process returns to steps 602 and 603, and the standby state is resumed.

If the input received in the shape point input mode is other than this, the input is treated as invalid and the process returns to steps 602 and 603 to enter the standby state again.

Next, the process of adding or deleting an input point once input will be described with reference to FIG. This processing is executed in step 604 of FIG. 6 when it is not the shape point input mode (that is, when it is the shape point addition / deletion mode).

First, it is determined what the input indicates (steps 702 to 704).

The input is the cursor 163 in the shape point measurement area.
When the button 131L is operated by pressing the button (that is, the user moves the cursor 163 and additionally inputs the contour point at the desired position of the frame 210) (step 702). ), Arithmetic control circuit 101
Receives and stores this coordinate input, and displays the input point 170J indicating the coordinate point (step 70).
5). Then, after that, a curve 180 (for example, a spline curve) that smoothly connects all the input points including the input point that is additionally input is calculated, and this is displayed on the display 110.
(Step 706, see FIG. 9E). Then, after that, the process returns to steps 602 and 603 in FIG. 6 to enter the standby state again.

The input is a cursor 163 in the shape point measurement area.
When the button 131R is operated by placing the button (step 703), the data and the display of the input point which is closest to the cursor 163 among the input points already input are deleted. (Step 707). After that, the process proceeds to step 706, a curve that smoothly connects the remaining input points is calculated, and this is displayed on the display 110. Then, the process returns to Steps 602 and 603 in FIG. 6 and enters the standby state again.

In addition to adding and deleting input points,
The input point that has already been input may be moved by dragging it with the mouse.

The input is the command "horizontal reference point input" 19
If it is the selection of 4 (step 704), the process proceeds to steps 617 to 619 of FIG. 6 to calculate the inclination and the like.

If the input is neither of the above, the process proceeds to step 608 in FIG.

Until a curve matching the frame is obtained,
The user can repeat the above-described processing of adding / deleting the input points as many times as necessary.

Next, regarding the processing at the end of the shape measurement,
This will be described with reference to FIG. This process is step 6 in FIG.
At 08, the command is executed when the command "end" 195 is selected.

First, it is determined whether or not there is uninput data (step 801). For example, the determination is made based on whether FPD data or the like is input, and whether at least three input points (shape points) are input.

If all the necessary data have been input, the process proceeds to step 802. Here, when the measurement target is a frame, the curve is corrected. The curve obtained by the above-described processing (FIGS. 6 and 7) shows the inner contour line of the frame. However, since the lens is fitted into the valley of the rim groove provided on the inner peripheral surface of the frame, what is actually required when ordering the lens is the shape of the valley position of the rim groove (see FIG. 11). Therefore, the above-mentioned input point and the curve connecting this input point are calculated in step 62 of FIG.
It is corrected so as to expand to the outer peripheral side by the depth of the rim input in 2 (see FIGS. 12 and 13 (a)). Generally, the depth of the rim groove is about 0.5 mm, and
It does not change so much from one to another. Therefore,
If 0.5 mm is designated as the initial setting value, it is considered that step 622 in FIG. 6 is not actually executed in many cases.

If the object to be measured is a dummy lens or a template, such correction of the rim groove is not necessary, and therefore the correction processing is not executed and the process directly proceeds to step 803.

In step 803, the process shown in FIG.
On the basis of the inclination data calculated in step 619, the inclination angle of the corrected input point (and the curve) is corrected (see FIG. 13B), and the process proceeds to step 804.

In step 804, the Y-coordinates of the upper and lower ends of the frame shape and the X-coordinates of the left and right ends of the frame shape are obtained from the equation of the curve connecting the corrected input points, and these geometric centers (so-called "") are calculated. Boxing center ") seek. Further, the coordinates of the input point after various corrections described above are converted into coordinate values with the boxing center as the origin. Further, the frame shape on the side that was not actually measured is calculated based on the data obtained by the processing so far (see FIG. 13D). This is possible because, in general, the shape of the spectacle frame is symmetrical on the right and left sides.

Finally, the obtained various data are output as a measurement result on the display screen (step 805), and the process is terminated.

In step 801, if uninput data remains, a display for confirmation is displayed on the display 110 (step 806). In this state, when "end" 195 is selected again, the processing is forcibly ended as it is. When the coordinate input is performed in a portion other than "end" 195, the process returns to steps 602 and 603 in FIG. 6 and waits for the input again.

By the processing shown in FIGS. 6, 7 and 8,
After obtaining the frame shape data and the like, it is transmitted to the lens manufacturer as ordering data together with other prescription data and the like.
Considering the communication cost, it is better that the length of data to be transmitted is shorter. Therefore, the operation control circuit 101 has a frame in advance.
The most similar shape pattern is obtained by storing the frame shape pattern and the classification data in which the size is classified and comparing the frame shape data obtained by the measurement with the classification data. Search for the pattern etc. and find the number of the pattern found,
Alternatively, only the size number may be transmitted as the shape data.

In the above description, the cursor 16 is used.
The movement of 3 and the selection of the command menu were performed mainly by using the mouse. However, it is not always necessary to use the mouse 130, and it is also possible to use the keyboard 120 or the like.

Next, another example of the frame fixing device 150 will be described with reference to FIGS. 14, 15 and 16.

In the example of FIG. 14, the lower part of the frame or template is
This is an example in which the lower backing plate 153 installed horizontally is supported so as not to fall, and is pressed and fixed to the display device 110 by the pressing cord 156. The lower backing plate 153 has an elongated plate shape, and its length is substantially equal to the lateral length of the display 110. Further, since the frame is curved, if only one side of the frame is pressed against the display screen, the display on the other side may rise from the surface and fall from the lower contact plate 153. In order to prevent such a problem, the width of the portion that supports the non-pressed side of the frame is wide. The lower backing plate stopper 1 is provided on both left and right ends of the lower backing plate 153.
54 is attached, and by fixing this to stopper receivers 155 provided on the left and right of the display 110, the lower contact plate 153 can be fixed at a predetermined height position of the display 110. The press cord 156 is made of a material having a high elasticity (for example, a rubber cord), and is stretched in the vertical direction by stopper receivers 155 provided above and below the display 110.

The example shown in FIG. 15 is an example in which the bottom part of the frame is supported by the horizontal pressing cord 157 instead of the lower end part of the frame. The point of using the presser cord 156 together is the same as the example of FIG. In this example, the frame is less likely to drop than in the example of FIG.

The example of FIG. 16 is similar to the example of FIG. 15 in that it supports the temple portion of the frame, but the structure for supporting is different. In this example, the flare receiving arm 158 extending from the upper portion of the display unit 110 is used to move the frame.
It supports the vine of the mu. This temple receiving arm is attached to an arm rotation supporting base 159 installed on the upper part of the display 110, and when not necessary, the temple receiving arm is provided.
It is possible to raise the bar upwards. Presser cord 15
The point that 6 is used together is the same as the example of FIG.

As described above, according to the above-described embodiment, it is possible to easily and accurately measure the shape of the frame or the like by using the information equipment such as the ordering terminal which has been widely introduced. As a result, there is no need to newly introduce a large-scale dedicated device or the like, which is advantageous in terms of cost. Also,
Easy to install in small stores. Furthermore, the influence of the skill of the measurer is small.

Further, in order to display the input point and the curve obtained by connecting the input points with the frame or the like superimposed,
It is possible to visually and easily confirm whether or not input is possible.

The shape measurement by the device of the present invention is not limited to spectacle frames and the like, but can be used to measure the shape of any object.
