Description

  The present invention relates to a technique for determining the degree of deterioration of a film material.

  Conventionally, there has been a film material as a building material. A film material as a building material is widely used because it has advantages such as obtaining a curved surface that cannot be obtained by other building materials and easily obtaining translucency depending on the material. For example, there are many things that use membrane materials as building materials, such as the roof of a huge stadium as a stadium, an exposition pavilion, and a tent-type warehouse.

By the way, when these membrane materials are used for a long period of time, the strength naturally decreases due to aging. Since the film material is often used as an outer shell of a building or a structure (hereinafter referred to as “building or the like”), there is a demand for examining the current strength of the film material being used.
It is generally difficult to examine the current strength of film materials used in buildings and the like. It is easiest to actually measure the strength by cutting a part of the used film material, but this leads to a decrease in the strength of the film material, and repairs the part of the film material that has been cut off afterwards. Even if it is done, the beauty of the membrane material will be lost.
Therefore, it is preferable to measure the current strength of the membrane material non-destructively, but since the membrane material is a thin material, it is widely used to non-destructively inspect the strength of concrete frames, reinforcing bars, etc. It is difficult to apply existing ultrasonic and X-ray technology.
On the other hand, the film material has a characteristic that the degree of strength reduction tends to appear on the surface. Many of the film materials used in buildings and the like are formed of resin at least on one side (for example, formed by coating at least one side of a base material formed into a film with fibers with resin). It is known as an empirical rule that the current strengths of these film materials have a strong correlation with, for example, cracks generated in the resin forming the surface of the film material. Using such an empirical rule, the current strength of a film material used for a building or the like is visually determined. However, this judgment largely depends on the experience and skill of the person making the decision, and it is difficult to eliminate the subjectivity of the person making the decision, so that the accuracy and objectivity of the judgment result are ensured. Is difficult.

  This invention makes it the subject to provide the technique for determining the intensity | strength at the present time of the film | membrane material used for a building etc. nondestructively, ensuring accuracy and objectivity.

  The present invention for solving the above-described problems is roughly divided into the following first and second inventions.

  The first invention relates to a technique for determining a current strength of a film material using a parameter called a color on a determination target surface of the film material having a strong correlation with the strength of the film material.

The first invention of the present application is first embodied as a determination device as follows.
1st invention is a determination apparatus which determines the degree of deterioration of the intensity | strength of the film | membrane material in which at least one side was formed with resin.
And this determination apparatus is the basic image about the basic image obtained by imaging the determination object surface which is the surface formed of resin of the object film material for which the degree of strength deterioration is determined by a predetermined imaging device Information relating to the color assigned to all pixels located within an appropriate range in the basic image on which the basic image data is based from the basic image data received by the receiving means, and the receiving means for receiving the data The color information is a set of a plurality of color systems, color analysis means for generating set color information, and by actually measuring the same kind of film material as the target film material, From the obtained strength information, which is information about the strength of the film material, and image data about an image obtained by imaging the surface formed of the resin of the film material with a predetermined imaging device A plurality of color systems in which reference color information, which is information related to colors assigned to all pixels located within an appropriate range of the image on which the image data is based, is used by the color analysis means The color analysis unit generates a reference unit color information generated as a set for each of various recording strengths in a state in which the intensity information and the reference group color information are associated with each other. The set color information and the plurality of reference set color information recorded in the recording unit, the plurality of color information included in the set color information, and the plurality of the set information included in the reference set color information. The reference color information that is determined to be the same as the reference color information that is the closest to the reference color information or the same as the reference color information by comparing with the similarity to the reference color information As well as determining information When the reference color information that is closest to the color information is determined, the color information that can be determined to be the same as the color information using the intensity information associated with the reference color information And determining means for determining a determination result of the strength of the target film material using intensity information estimated to be associated with the set color information.
If this determination apparatus is explained conceptually, a basic image obtained by imaging a determination target surface, which is a surface formed of a resin of a target film material whose strength deterioration degree is determined, with a predetermined imaging device. (Or data obtained therefrom. This is basic image data) is a film material of the same type as that of the target film material recorded in the recording means, and an image pickup device that actually has a reduced strength. The strength of the target film material is determined by comparing with an image (or image data obtained therefrom) obtained by imaging. In the recording means, a plurality of pieces of intensity information relating to the actually measured values of the film material strength obtained from the film material whose strength has been reduced can be obtained by imaging an image whose strength has actually decreased due to aging deterioration with an imaging device. Are recorded in association with a plurality of images (or image data obtained from the images). In this determination apparatus, the determination means provided in the determination apparatus determines at least one similar to the basic image data, and determines the strength of the target film material from the strength information associated with the image. Yes.
As a result, this judgment device compares the basic image with the image actually obtained by imaging the film material with reduced strength without relying on humans, thus ensuring accuracy and objectivity. However, it is possible to determine the current strength of the film material used for a building or the like in a non-destructive manner.

The strength of the target membrane material It is adapted to determine the results. In this determination, for example, when determining the reference color combination information most similar to the color combination information, the intensity information associated with the determined reference color combination information is the same as the color combination information. When the combination color information obtained based on the reference combination color information that can be determined is determined, the intensity information that is estimated to be associated with the combination color information itself is used as the intensity information of the target film material. Alternatively, some correction may be performed on the intensity information, and the value after the correction may be used as the intensity information of the target film material. When determining the combination color information obtained based on the reference combination color information that can be determined to be the same as the combination color information, the combination color information different from the reference combination color information is obtained from the target film material. In some cases, it is determined that the color information is closest (or similar) to the combination color information. This is the combination color information that exists between the reference combination color information that is obtained from the same type of film material as the target film material and the closest reference combination color information in the intensity information. Can be obtained by calculation from the reference color combination information recorded in the recording means. The intensity information estimated to be associated with the set color information can be obtained by performing calculations using the reference set color information and the intensity information recorded in the recording means. Note that two or more reference color combination information is determined to be similar to the color combination information, and based on a plurality of pieces of intensity information associated with the plurality of reference color combination information (for example, taking an average, You may determine the intensity | strength information of an object film | membrane material by calculating | requiring a median value. The method of determining the intensity information as described above may also be performed in the case of the second invention described later.

The camera 200 corresponds to the imaging apparatus or imaging means of the present invention. In this embodiment, the camera 200 is a long and thin microscope as shown in FIG. As an example of such a microscope, SZ-7000 (trademark) of SCARA Co., Ltd. can be mentioned.
The camera 200 includes an elongated case 210 that can be held by hand. A hole 211 is opened at the tip of the case 210. With the hole 211 in contact with the imaging object, the camera 200 performs imaging. The case 210 is provided with a shutter button 212, and a still image can be taken by operating the shutter button 212.
In the case 210, although not shown, an image pickup device that is a CCD, for example, that performs image pickup, and an optical system that guides image light from the image pickup object to the image pickup device so that the image pickup object can be enlarged and imaged A light source that is, for example, an LED that irradiates the imaging object with illumination light through the hole 211 is incorporated. Since the optical system is focused on the hole 211 portion of the case 210, the camera 200 is an imaging target in a focused state simply by bringing the tip hole 211 into contact with the imaging target. Enlarged imaging of objects can be performed. In addition to being able to capture an enlarged image while suppressing camera shake, such a camera 200 captures only light from a built-in light source as illumination light, so that the imaging condition can be kept constant at a specified condition. Therefore, it is compatible with this determination system.
The camera 200 captures image data (basic image data in the present invention) by imaging a determination target surface, which is a surface formed of a resin of a film material (target film material) whose strength is to be determined, as will be described later. (Hereinafter referred to as basic image data).
In addition, as shown in the sectional view of FIG. 2 (A) and the exploded view of FIG. 2 (B), the target film material 300 in this embodiment is made by weaving fibers 310, which are polyester fibers, in this embodiment. In this embodiment, both surfaces of the substrate 311 formed in this way are covered with a resin 320 which is PVC (polyvinyl chloride). Note that other materials may be used for the fibers 310 and the resin 320, and the resin 320 may cover only one surface of the substrate 311. The determination target surface is the both surfaces of the target film material 300 because both surfaces of the target film material 300 of this embodiment are covered with the resin 320, but only one surface of the target film material 300 is covered with the resin 320. If not, only the surface covered with the resin 320 becomes the determination target surface.
The basic image data includes information about colors (that is, the basic image is a color image). In this embodiment, the basic image data is a basic image obtained by imaging the target film material 300 at one of two magnifications of 140 times and 40 times. The basic image data is 608 pixels wide and 464 pixels long. The size of the pixel. The range reflected in the basic image is approximately 2 mm (long side direction of the basic image) in the case of 140 times and approximately 6 mm in the case of 40 times. The magnification can be changed, for example, by exchanging an optical system built in the case 210. The basic image is picked up so that the vertical and horizontal directions match the direction of the fibers 310 that are passed vertically and horizontally. However, it is possible not to capture the basic image as such. In that case, the determination apparatus 100 performs correction so that the basic image is in such a direction.
For example, the camera 200 can be connected to the determination apparatus 100 via a USB cable 220 in a wired manner, and can transmit basic image data to the determination apparatus 100.
However, the camera 200 may be configured to send the basic image data to the determination apparatus 100 wirelessly, for example, by infrared rays. When the camera 200 includes a detachable recording medium such as a memory card, the basic image data may be sent to the determination apparatus 100 via the recording medium.
Note that the basic image data is not necessarily generated by the camera 200. When the camera 200 is a silver salt camera, basic image data may be generated by reading an image obtained by developing a film imaged by the camera with a scanner or the like and sent to the determination apparatus 100.

Next, the determination apparatus 100 will be described.
A computer serving as the determination apparatus 100 includes a disk drive. A recording medium R composed of a CD-ROM, a DVD-ROM, or the like is inserted into the disk drive, and a program recorded on the recording medium R can be read. The determination apparatus 100 is installed with the program according to the present invention through the above-described process, and has each function required for the determination apparatus 100 of the present invention. However, the above-described program does not necessarily have to be installed in the determination apparatus 100 via the recording medium R, and may be installed in the determination apparatus 100 by distribution via a network such as the Internet. Note that a part of the program (or a part of data necessary for executing the program) may be prevented from being installed in the determination apparatus 100. In that case, the determination apparatus 100 executes the following processing while reading out necessary data from the recording medium R inserted in the disk drive.
In addition, this program may be a program that can cause a computer to function as the determination apparatus 100 of the present invention alone, and in cooperation with an OS installed in the computer or other programs. The computer may have a function as the determination device 100 of the present invention.

The hardware configuration of the determination apparatus 100 is shown in FIG.
In this embodiment, the determination apparatus 100 is connected to a central processing unit (CPU) 111, a read only memory (ROM) 112, a hard disk drive (HDD) 113, a random access memory (RAM) 114, and an interface 115. And a bus 116.
The ROM 112 or the HDD 113 stores the OS, the above-described program according to the present invention, and predetermined data (this includes reference color combination information, reference form information, and intensity information described later). The CPU 111 controls the determination apparatus 100 as a whole, and executes processing to be described later based on programs and data stored in the ROM 112 or the HDD 113. The RAM 114 is used as a working storage area when the CPU 111 performs processing.
The interface 115 serves as a window for exchanging data between the determination apparatus 100 and the outside. The interface 115 is configured to receive an input from the input device 102. In addition, basic image data is received from the camera 200. To enable this, the interface 115 includes a connection terminal for receiving a connection terminal at the end of the USB cable 220. The interface 115 can also receive the program of the present invention from the disk drive. The interface 115 also sends display control data for displaying an image on the display 101 to the display 101. The display 101 that has received the display control data displays an image based on the display control data.

By executing the above-described program, the CPU 111 built in the determination apparatus 100 of the present invention forms the following functional blocks.
That is, as shown in FIG. 4, the data receiving unit 121, the data processing unit 122, and the data output unit 123 are formed inside the determination apparatus 100.

The data receiving unit 121 receives basic image data generated by being captured by the camera 200. The data receiving unit 121 in this embodiment receives basic image data via the USB cable 220 and the interface 115 that connect the camera 200 and the determination apparatus 100. The data receiving unit 121 is configured to receive an input from the input device 102 via the interface 115.
When the basic image data or the input from the input device 102 is received, the data receiving unit 121 analyzes the content and sends it to the data processing unit 122.

  The data processing unit 122 determines the strength of the target film material based on the basic image data. After determining the strength of the target film material, the data processing unit 122 sends information about the determined strength to the data output unit 123 in order to display the information about the determined strength on the display 101. . The data output unit 123 generates display control data for displaying information on intensity on the display 101 based on the data, and sends the display control data to the display 101 via the interface 115. . The display 101 that has received this displays an image including information on the strength of the target film material.

More specifically, the data processing unit 122 is formed as shown in FIG.
The data processing unit 122 includes a control unit 122A, a color analysis unit 122B, a form analysis unit 122C, a determination unit 122D, and a recording unit 122E.

  The control unit 122A controls the entire processing for determining the strength of the target film material based on the basic image data. Under the control of the control unit 122A, the color analysis unit 122B, the form analysis unit 122C, and the determination unit 122D perform the following processing. For example, the determination apparatus 100 according to this embodiment can determine the strength of the target film material in three modes, but controls which mode determines the strength of the target film material. The unit 122A performs. The three modes executed by the determination apparatus 100 according to the present embodiment are modes for determining the current strength of the film material using only color combination information (described later) as information generated from the basic image data (hereinafter referred to as “color”). Mode ”), a mode for determining the current strength of the film material using only morphological information (described later) as information generated from the basic image data (hereinafter referred to as“ morphological mode ”), and a basic image. In this mode, the current strength of the film material is determined using both the combination color information and the form information as information generated from the data (hereinafter referred to as “color / form mode”). Which of the three modes is executed is determined by the control unit 122A according to the result of the input sent from the input device 102 via the data receiving unit 121. If it is determined that the color mode is to be executed, the control unit 122A determines that the color / morphology mode is to be sent to the color analysis unit 122B and the determination unit 122D, and if it is determined that the configuration mode is to be executed, to the shape analysis unit 122C and the determination unit 122D. When it is determined to execute, an instruction is sent to the color analysis unit 122B, the form analysis unit 122C, and the determination unit 122D that the process for performing the determination can be performed.

The color analysis unit 122B receives basic image data via the data reception unit 121, and generates color combination information based on the received basic image data.
When the color analysis unit 122B receives the above instruction from the control unit 122A, the color analysis unit 122B generates color combination information as follows.
In order to generate color combination information, an appropriate range in the basic image is first extracted. As described above, in this embodiment, the width of the determination target surface reflected in the basic image is about 2 mm when the magnification is 140 times and about 6 mm when the magnification is 40 times. In this embodiment, although not necessarily limited thereto, the entire range in the basic image is taken out. However, a part of the basic image having a width of 1 mm from the left side in the basic image may be set as an “appropriate range” to be extracted from the basic image.
Next, information (hereinafter referred to as “pixel value”) for determining the color displayed by the pixel assigned to all the pixels within the range is extracted. This pixel value extraction is performed for a plurality of color systems. In this embodiment, four color systems of RGB, HSV, XYZ, and L ^* a ^* b ^* are used. However, the number of color systems to be used is not necessarily four. A color system other than the color system may be used. Note that the color system to be used may be changed by an input from the input device 102 received via the interface 115 and the data receiving unit 121, for example. This input is received by, for example, the control unit 122A, and the control unit 122A that has received the input sends an instruction to use the color system to the color analysis unit 122B, and the color analysis unit 122B that has received the instruction receives the color specification. The system can be used.
Next, when the extraction of the pixel values assigned to all the pixels within the range is finished for the four color systems, the pixel values of each color system are statistically processed, and the following color index Is generated. Although not necessarily so, in this embodiment, there are a plurality of color indexes.
The color index used in this embodiment includes six types of pixel values: variance, mode value, average value, maximum value, minimum value, and median value. The color index is not limited to this, and may include others, or some of them may be lacking. In this way, a plurality of color indexes are generated for each of the four types of color systems. Note that the color index to be used may be changed by an input from the input device 102 received via the interface 115 and the data receiving unit 121, for example. This input is received, for example, by the control unit 122A, and the control unit 122A that has received the input sends an instruction to use the color index to the color analysis unit 122B, and the color index is received by the color analysis unit 122B that has received the instruction. Can be used.
The color information in the present invention is a collection of color indexes for a certain color system. In this embodiment, color information (that is, four types of color information) corresponding to each of the four color systems of RGB, HSV, XYZ, and L ^* a ^* b ^* is used. A set of the four types of color information is combined color information in the present invention.
In this embodiment, color combination information is generated as a set of four types of color information each including six types of color indexes. When the film material is deteriorated by use and its strength is reduced, the color of the surface of the film material is changed. Therefore, this color combination information has a correlation with the strength of the film material.
The color analysis unit 122B is configured to send the generated set color information (or data about it) to the determination unit 122D.

The morphological analysis unit 122C receives basic image data via the data receiving unit 121, and generates morphological information based on the received basic image data.
The morphological information includes the characteristics of the resin 320 of the target film material 300 shown in the basic image that is the basis of the basic image data, cracks generated in the resin 320, and the fibers 310 exposed from the resin 320. This is quantified information. The fibers 310 appear on the surface of the film material 300 due to wear of the resin 320 due to deterioration over time. The crack appears on the resin 320 on the target film material 300 due to deterioration over time. Since these have a strong correlation with the degree of decrease in the strength of the target film material, the form information has a strong correlation with the decrease in the strength of the film material.
When the form analysis unit 122C receives the above instruction from the control unit 122A, the form analysis unit 122C generates the form information as follows.

The morphological analysis unit 122 </ b> C recognizes the resin 320, cracks, and fibers 310 exposed from the resin 320 in the basic image, by performing region division processing on the basic image. The region division is performed by discriminating (clustering) what each pixel represents of the resin 320, the crack, and the fiber 310. Any clustering method may be used. Either a supervised discrimination method or an unsupervised discrimination method may be used. As the supervised discrimination method, for example, the K Nearest Neighbor Method or Decision tree can be used. As an unsupervised discrimination method, for example, the k-means method can be used.
In the case of using the K nearest neighbor determination rule, in order to cluster the pixel values of the pixels to be clustered, a number of known ones are known that each represents a resin 320, a crack, or a fiber 310. Are used. Pixel values are arranged in a predetermined coordinate space, and an appropriate number (for example, three) of pixel values close to the pixel value of the target pixel is selected from among known pixel values, and these are selected as resin 320, crack, Depending on which of the fibers 310 corresponds to, the target pixel is clustered into one of the resin 320, the crack, and the fiber 310. If the selected pixel does not concentrate on any of the resin 320, crack, and fiber 310, in this embodiment, the pixel corresponds to any of the resin 320, crack, or fiber 310 by majority vote. To decide.
The decision tree method is a method in which a plurality of conditions are set, a solution for whether or not these conditions are satisfied is obtained, and objects are clustered according to the combination of the solutions. In the case of this embodiment, the pixel value of each pixel is obtained by a plurality of color systems similarly to the case where the set color information is used, and three elements (for example, R, G, etc.) included in the plurality of color systems are obtained. , B), a combination of solutions to whether the pixel value of the pixel exceeds a predetermined threshold set based on past experience, the target pixel is a resin 320, a crack, and a fiber 310. Determine which of the following is true. In addition to or in place of these, appropriate conditions such as the sum or difference of pixel values when expressed in each color system can be used as the above-described plurality of conditions.
The k-means method is a method for clustering samples into a predetermined number of clusters, and is used recently in the field of data mining, etc., which is used when only the number of clusters is determined from the beginning. It is a technique. In this embodiment, the samples are clustered into three or more clusters. Although not necessarily limited to this, in this embodiment, three of resin 320, crack, and fiber 310 are selected as clusters. In this method, first, center samples corresponding to the number of clusters (three in this embodiment) are appropriately set in a predetermined virtual space where a large number of samples exist. Then, a large number of clusters are clustered into a central sample that is the closest to them. Next, in each cluster, the center position of the samples clustered in the cluster is obtained. And let it be a new central sample. This process is repeated until the central sample converges and stops moving. Thereby, each sample is clustered at once into a predetermined number of clusters. In this embodiment, the k-means method is executed using the pixel value of each pixel as a sample.
Clustering is performed by any one of the methods described above, and in this embodiment, image recognition of the basic image is performed and what is reflected in the basic image is grasped.
Next, in this embodiment, the morphological analyzer 122C divides the basic image. In this embodiment, the basic image is divided into a plurality of rectangular regions adjacent to each other in the vertical and horizontal directions with the intersection of the vertical fibers and the horizontal fibers appearing in the basic image as vertices, or in the vertical direction. This is done by dividing the basic image into a plurality of rectangular regions adjacent to each other in the vertical and horizontal directions, with the intersection at which the direction fibers and the horizontal fibers intersect. In this embodiment, the basic image is divided into a plurality of rectangular regions that are adjacent to each other in the vertical and horizontal directions around the intersection where the vertical fibers and the horizontal fibers intersect. In the case of performing such processing, how to obtain the intersection where the longitudinal fibers and the transverse fibers intersect will be described below.
In order to obtain the intersection where the longitudinal fibers and the transverse fibers intersect, first, the image is binarized. In the binarization, in a suitable range of image recognition (in this embodiment, this “appropriate range” is the entire basic image) of the basic image, the area and background recognized as fibers are black and white. Divide into In this embodiment, the basic image is converted into a binarized image in which the area recognized as the fiber is white and the background is black. In this embodiment, for the purpose of noise removal, the basic image converted into black and white is subjected to the shrinkage and expansion processing twice known for the purpose of hole filling and arc point removal in the binary image. I am doing so. By performing the contraction and expansion processing, the monochrome image changes as shown in FIG. Note that leveling processing may be performed between the contraction and expansion using, for example, a Gaussian function. As a result, noise can be further removed. Note that the image used for binarization need not be the basic image itself. For example, a basic image obtained by clustering each pixel into three using the k-means method (this corresponds to a ternary basic image) can be used for binarization. FIG. 6 is a diagram illustrating an example of an image when such clustering is performed and then leveling is performed using a Gaussian function.
Next, the following processing is performed on each of the portions that are collectively whitened in the binarized image. FIG. 7 shows an example of a fiber region (fiber region F) in the binarized basic image. For this fiber region, the length in the longitudinal direction (Y coordinate direction) of the fiber region F is determined at each location in the lateral direction (X coordinate direction). FIG. 7 conceptually illustrates a state in which the processing for obtaining the length in the longitudinal direction of the fiber region F is performed only at three locations Y ₁ , Y ₂ , and Y ₃ , but this is actually illustrated in the X coordinate direction. Do in all positions. In this embodiment, the structure of the film material 300 that is the target film material is as shown in FIG. 2, and the thickness of the resin 320 that covers the portion where the fibers 310 that run vertically and horizontally overlap each other is as follows. It is thinner than the part. Therefore, it can be expected that the fibers 310 are exposed on the surface of the target film material 300 in a portion where the fibers 310 overlap. Utilizing this fact, in this embodiment, a portion of the fiber region F having the longest length in the longitudinal direction is determined as a portion overlapping the warp warp. Similarly, the part with the longest length in the horizontal direction in a certain fiber region F is determined as the part overlapping the weft yarn of the warp. In Figure 7, the vertical length of the fiber areas F is long in a portion of the Y _2, where coordinates determined that it overlapping portions the weft warp. Such a process is performed on each fiber region F. In the fiber region F, the coordinates of the portion of the weft yarn that overlaps the warp yarn or the coordinates of the portion of the warp yarn that overlaps the weft yarn are corrected, and the object reflected in the basic image is corrected. The intersection of the fibers running in the vertical and horizontal directions in the membrane material 300 is determined. Then, the binarized basic image is divided into rectangular regions centered on the intersection determined as described above. An example of the divided basic image after binarization is shown in FIG. The broken lines in FIG. 8 indicate positions where it is determined that there are fibers running in the vertical and horizontal directions. The solid line in FIG. 8 is a boundary line that divides the basic image into a rectangle centered at the intersection of fibers running vertically and horizontally. A range surrounded by the boundary line is a rectangular area.
Next, the shape analysis unit 122C quantifies the characteristics of the resin 320, cracks, and fibers 310 shown in the basic image. This quantification may or may not be performed from a basic image divided into rectangular regions. For the basic image divided into rectangular areas, the basic image before binarization is simply applied with the rectangular area as shown in FIG. 8, and the basic image after binarization. Both of those shown in FIG. 8 in which a rectangular area is applied are included.
In this embodiment, the parameters used for quantifying the form of the target film material 300 are as follows. The following parameters are not necessarily all used, and parameters other than the following parameters may be used. Which parameter is used can be made variable by input from the input device 102.
The parameters for the fiber can be as follows.
1. Average value of the area of the fiber regions (regions where the fibers are reflected) included in each of the plurality of rectangular regions 2. Standard deviation of the area of the fiber regions included in each of the plurality of rectangular regions 3. Among the plurality of rectangular regions, the area of the largest one of the fiber regions included therein 4. The average value of the lengths in the vertical direction and the average value of the lengths in the horizontal direction of the plurality of fiber regions At least one of the plurality of fiber regions having the maximum length in the longitudinal direction and at least one of the maximum values having the maximum length in the horizontal direction 6. Of the plurality of rectangular regions Number of things including fiber regions The parameters for cracks and resin can be as follows.
7. Number of cracks included in a reference range (for example, a range including all rectangular regions) which is a predetermined range of the basic image / all crack regions shown in the reference range (regions where cracks are shown) ) And the sum of the areas of all the resin areas (areas where the resin is reflected) 8. Sum of the areas of all the crack areas included in the reference range / all the crack areas reflected in the reference range In this embodiment, among the parameters 1 to 8, it is 1, 2, 3 and 6 that the basic image divided into rectangular regions must be used in this embodiment. .
In addition, the length in the vertical direction and the length in the horizontal direction of the fiber region in the parameters 4 and 5 ignore the frame of the rectangular region, and the fiber region in the portion where it is determined that there is a fiber in the basic image. Measured as length in the vertical or horizontal direction. For example, the lateral length of the fiber region is measured as t ₃ to t ₆ in FIG. In addition, when the wear of the resin is large and the adjacent fiber regions that were separate at the beginning (period when the wear of the resin is not large) are connected to each other (for example, t ₄ and t _{5 in} FIG. And the length of the whole connected fiber region is determined as the length of the fiber region.
In this way, morphological information is generated.
The morphological analysis unit 122C sends the generated morphological information (or data about it) to the determination unit 122D.

The determination unit 122D performs the following processing based on the above instruction received from the control unit 122A.
When the color mode is executed, the determination unit 122D compares the combination color information received from the color analysis unit 122B with the reference combination color information (or data thereof) read from the recording unit 122E, so that the target film The current strength of the material 300 is determined.
When the configuration mode is executed, the determination unit 122D compares the configuration information received from the configuration analysis unit 122C with the reference configuration information (or data thereof) read from the recording unit 122E, so that the target film material 300 Determine the current strength of.
When the color / form mode is executed, the determination unit 122D reads the combination color information received from the color analysis unit 122B and the form information received from the form analysis unit 122C from the recording unit 122E. And the intensity | strength in the present time of the object film | membrane material 300 is determined by comparing with reference | standard form information (or those data).
The data recorded in the recording unit 122E is the following data for a plurality of types of film materials that are scheduled to be subjected to strength determination by the determination device 100.
The recording unit 122E has a determination device based on strength information about the strength of the film material obtained by actually measuring the film material whose strength has actually dropped as a sample, and an image obtained by imaging the sample. The combination color information generated through the same process as that for creating the combination color information from the basic image 100 and the reference combination color information that is the same kind of information are recorded in a state of being associated with each other. The reference color combination information includes color information (reference color information in the present invention) corresponding to all the color information that can be included in the color combination information (that is, all that may be used to create color information). And data on all color indexes that can be included in the set color information.
In the recording unit 112E, the same kind of information as the morphological information generated through the same process as the determination device 100 creates the morphological information from the basic image from the image obtained by imaging the film material whose strength has actually decreased with the sample. Is recorded in a state in which it is associated with the intensity information. The reference form information includes information on all parameters that can be included in the form information.
Note that the strength information of this embodiment is the current strength of the target membrane material 300 (in this embodiment, this is not necessarily so, but the average of the tensile strength in the vertical and horizontal directions is defined as the strength of the membrane material. )) Is information indicating how many percent of the target film material 300 remains as compared with the case where the target film material 300 is new. However, the strength information does not necessarily have to be such, for example, either the longitudinal tensile strength or the lateral tensile strength of the target film material 300, or the average of these or the longitudinal and transverse tensile strengths. The value itself may be used.

When the determination unit 122D executes the color mode, the determination unit 122D displays the combination color information, the reference combination color information, and the plurality of pieces of color information included in the combination color information. The color combination information generated by the color analysis unit 122B is compared with one expressed by the same color system among the plurality of reference color information included in the color information. The combination color information that can be determined to be similar or the same as the combination color information generated by the color analysis unit 122B is determined. In determining the reference color combination information or the combination color information by comparing the color information with the reference color information, information on the color index that is included in both the color information and the reference color information is used. For such determination, multiple regression analysis, which is a general method of multivariate analysis, or M5P (tree-based piecewise linear models) can be used.
In this way, the determination unit 122D has the same color combination information generated by the color analysis unit 122B as the color combination information generated by the color analysis unit 122B is most similar to which of the plurality of reference color combination information. It is determined what color combination information can be determined. The determination unit 122D obtains intensity information associated with the determined reference color combination information (or estimated to be associated with the color combination information described above), or obtained by performing some correction on the intensity information. The obtained information on the strength of the target film material 300 at that time is generated as final information to be finally output. It should be noted that the determination of the intensity information from the combination color information and the reference combination color information can be regarded as a regression analysis in which various color indexes included in the combination color information are used as explanatory variables and the intensity information is used as target information. There are cases where it is possible.
Note that the determination unit 122D determines that two or more pieces of reference color information are similar to the color combination information generated by the color analysis unit 122B, and a plurality of pieces of reference color information associated with the plurality of pieces of reference color information. Based on the strength information (for example, taking an average or obtaining a median), the strength information of the target film material may be determined.
When it is the form mode that is executed, the determination unit 122D compares the form information with the reference form information, so that the form information generated by the form analysis unit 122C is the one of the plurality of reference form information. Morphological information that can be determined to be most similar to the morphological information generated by the morphological analysis unit 122C is determined. In determining the reference form information or the form information by comparing the form information with the reference form information, information on the above-mentioned parameters included in common is used. For such determination, multiple regression analysis, which is a general method of multivariate analysis, or M5P can be used.
In this way, the determination unit 122D determines that the morphological information generated by the morphological analysis unit 122C is the most similar to which of the plurality of reference morphological information, or is the same as the morphological information generated by the morphological analysis unit 122C. Determine what form information you can do. The determination unit 122D is obtained by performing some correction on the intensity information itself associated with the determined reference form information (or estimated to be associated with the above-described form information), or the intensity information. Then, information about the strength of the target film material 300 at that time is generated as final information to be finally output. It should be noted that the determination of the intensity information from the form information and the reference form information may be understood as a regression analysis when various parameters included in the form information are used as explanatory variables and the intensity information is used as the target information. .
Note that the determination unit 122D determines that two or more pieces of reference form information are similar to the form information generated by the form analysis unit 122C, and determines the plurality of pieces of intensity information associated with the plurality of pieces of reference form information. Based on (for example, taking an average or obtaining a median), the strength information of the target film material may be determined.
When it is the color / form mode that is executed, the determination unit 122D executes the process for the color mode and the process for the form mode. In this case, the determination unit 122D compares the combination color information and the reference combination color information as in the color mode, and compares the form information and the reference form information as in the form mode. And the final intensity information may be determined based on (for example, on average) the intensity information obtained in each processing, or the combination of the combination color information and the form information and the reference combination color The combination of the information and the reference form information is collectively compared, and the reference set color information and the reference form that are most similar to the combination of the set color information generated by the color analysis unit 122B and the form information generated by the form analysis unit 122C The combination of information, or the combination of combination color information and form information that can be determined to be the same as the combination of combination color information generated by the color analysis unit 122B and form information generated by the form analysis unit 122C is determined. For such determination, multiple regression analysis, which is a general method of multivariate analysis, or M5P can be used.
The determination unit 122D includes the intensity information itself associated with the determined combination of reference color information and reference form information (or estimated to be associated with the combination of the above-described combination color information and form information), or the information Information on the intensity of the target film material 300 at that time point obtained by correcting the intensity information (for example, averaging a plurality of intensity information or taking the median of the plurality of intensity information) And finally generated as final information to be output. Note that the intensity information from the combination color information and the form information and the reference combination color information and the reference form information is determined using the color index included in the combination color information and the parameter included in the form information as explanatory variables. In some cases, it can be understood as a regression analysis when the target information is used.
In any case, the final information is sent to the data output unit 123. The data output unit 123 that has received it generates display control data to display an image corresponding to the final information on the display 101, and sends it to the display 101. Receiving this, the display 101 displays an image on the display 101 so that the user can visually recognize the final information.

The determination device 100 described above was used to determine the current strength of the target film material 300, and then the current strength of the target film material 300 was actually measured to check the accuracy of the determination result. The results are shown in Table 1.
