Summary of the Invention

Problems to be Solved by the Invention

[0005] Iron bacteria sludge is a brown deposit adhering to the inner wall surface of a tunnel or the like. When a large amount of iron bacteria sludge is generated and deposited, not only does it look dirty, but for example, it causes the sediment to scatter and become contaminated by the wind when a vehicle passes. In addition, when iron bacteria sludge accumulates on facilities such as water collection pipes, drainage ditches, and drain pipes installed in a tunnel or the like, problems such as stagnant water and flooding occur due to insufficient drainage, and vehicles cannot pass, and metal members such as rails and fixtures rust. Therefore, as part of maintenance work in a tunnel or the like, a removal work of iron bacteria sludge using a remover is generally performed.

Modes for Carrying Out the Invention

[0022] The embodiments will be described in detail.

[0023] <Information Processing Device> The information processing device 100 according to this embodiment is a device that outputs the required amount of removal agent needed to remove iron bacteria sludge, which is an example of a material to be removed that has formed on the wall surface of a tunnel, which is an example of a structure to be inspected. The information processing device 100 can accurately calculate the amount of iron bacteria sludge and the amount of removal agent needed to remove the iron bacteria sludge.

[0024] The structures to be inspected include, for example, tunnels, preferably tunnel walls, but are not limited to these. Other structures such as culverts, various buildings, and various structures that are difficult for people to access, as well as their walls, may also be used. Furthermore, the material to be removed is not limited to iron bacteria sludge, but may also include various other deposits. Deposits such as iron bacteria sludge tend to spread thinly on the wall surface. In addition, it is preferable to use a removal agent that is applied by spraying it onto the surface of the material to be removed. For this reason, in this specification, the amount of material to be removed is calculated by determining the area of ​​the region where the material to be removed is located. Furthermore, in this specification, the region of material to be removed in a structure to be inspected refers to the extent of material to be removed that is spread on the surface of the constituent members of the structure to be inspected, such as the wall surface, ground, and equipment surface.

[0025] [Hardware configuration] Figure 1 is a block diagram showing an example of the hardware configuration of the information processing device 100 in this embodiment.

[0026] The information processing device 100 is composed of a computer and includes, for example, a CPU (Central Processing Unit) 110, RAM (Random Access Memory) 111, ROM (Read Only Memory) 112, storage device 113, input / output I / F (Interface) 114, communication unit 115, input unit 116, and display unit 117, all interconnected by a bus 101.

[0027] The CPU 110 is connected to each element of the information processing device 100 via the bus 101 and controls the entire information processing device 100 together with each element. The CPU 110 may be composed of a general-purpose CPU, an application-specific integrated circuit (ASIC), a DSP (Digital Signal Processor), a GPU (Graphics Processing Unit), or the like.

[0028] RAM 111 has a working area for various programs stored in ROM 112 and storage device 113 to operate, and an area for temporarily storing transmitted and received data. ROM 112 stores boot programs, etc. Storage device 113 consists of a solid-state drive, hard disk drive, etc., which is built into or attached to the information processing device 100, and stores various programs for operating the information processing device 100, as well as various setting data used when these programs operate. RAM 111 and storage device 113 function as a storage unit 215, which will be described later.

[0029] The input / output interface 114 controls the input and output of data and control signals between the CPU 110 and other elements within the information processing device 100, or between the information processing device 100 and other devices. Other devices include, for example, imaging devices such as cameras connected to the information processing device 100. Furthermore, the input / output interface 114 may also control the input and output of data with devices (not shown) for reading or writing to other recording media.

[0030] The communication unit 115 is a network connection interface for communication between the information processing device 100 and external devices. The communication unit 115 may be a network interface for connecting to a wired line or a network interface for connecting to a wireless line. The information processing device 100 can connect to networks such as mobile phone networks, public switched telephone networks (PSTN), VPNs (Virtual Private Networks), LANs (Local Area Networks), and WANs (Wide Area Networks) via the communication unit 115. In this way, it can communicate with other computers via the network and exchange signals with other devices. Smartphones, tablet terminals, etc., may also be connected to the communication unit 115. Furthermore, imaging devices such as cameras may also be connected to the communication unit 115. In addition, as will be described later, order information may be transmitted to the supplier via the communication unit 115.

[0031] The input unit 116 is a device that accepts user input such as a keyboard or mouse. The display unit 117 is composed of a liquid crystal display, an organic EL display, a printing device, etc. The display unit 117 displays various information according to instructions from the CPU 110. The input unit 116 and the display unit 117 may be integrated and implemented as a touch panel.

[0032] Although the information processing device 100 shown in Figure 1 does not have an imaging device, it may be a device that incorporates an imaging device. Furthermore, the information processing device 100 may be integrated with an imaging device and implemented as a smart device such as a smartphone, tablet, smart glasses, or drone.

[0033] <Functional Configuration> Figure 2 is a block diagram showing the functional configuration of the information processing device 100 according to the embodiment.

[0034] As shown in Figure 2, the information processing device 100 includes a reference quantity acquisition unit 201, an image acquisition unit 202, an image processing unit 203, an area calculation unit 204, and a required quantity calculation unit 205. The information processing device 100 also includes at least one of a display processing unit 206 and a transmission unit 207. In Figure 2, a solid arrow indicates that the information processing device 100 includes a display processing unit 206 but not a transmission unit 207, a dashed arrow indicates that it includes both a display processing unit 206 and a transmission unit 207, and a dashed-dot arrow indicates that it does not include a display processing unit 206 but does include a transmission unit 207.

[0035] [Reference amount acquisition part] The reference quantity acquisition unit 201 acquires the amount of removal agent required to remove iron bacteria sludge per unit area as a reference quantity. The reference quantity information is stored, for example, in the removal agent information database in the storage unit 215 of the information processing device 100, linked to the type of removal agent, manufacturer information, supplier information, etc. The reference quantity acquisition unit 201 acquires the corresponding reference quantity from the information stored in the removal agent information database based on the type of removal agent entered by the user via the input unit 116, for example. Alternatively, the user may directly input the reference quantity via the input unit 116. In this case, the reference quantity acquisition unit 201 acquires the information entered via the input unit 116 as the reference quantity.

[0036] [Image acquisition section] The image acquisition unit 202 acquires an image from an imaging device 301, such as a camera, which is generated by the imaging device 301, as an image that includes the entire iron bacteria sludge on the tunnel wall and the measurement reference. The image may be a still image or a video. If the image is a video, the image acquisition unit 202 acquires, for example, each frame of the video as the image described above.

[0037] Furthermore, from the viewpoint of calculating the area more accurately, it is preferable to photograph the surface of the structure under inspection where iron bacteria sludge is present from a direction approximately perpendicular to it. Note that "approximately perpendicular" means the direction normal to the surface, or, if it is a direction deviating from the normal direction, a direction in which the angle of inclination with respect to the normal direction is, for example, 10° or less. If the image is taken from a direction that is not nearly vertical (for example, a direction where the tilt angle exceeds 10°), the captured image may be edited using, for example, a deformation tool in the image editing software attached to the imaging device 301 to change the viewpoint by adjusting the angle, and the edited image may be acquired as the image. Also, if the image is acquired from a direction that is not nearly vertical, the above editing may be performed in, for example, the image processing unit described later.

[0038] Furthermore, from the viewpoint of calculating a more accurate area, it is preferable to photograph the image so that the iron bacteria sludge is positioned approximately in the center of the image. Note that "the iron bacteria sludge is positioned approximately in the center of the image" means one of the following two things: The first is that the iron bacteria sludge is positioned in the image so that its center (for example, the centroid of the polygon when the outline of the entire iron bacteria sludge in the image is approximated by a polygon) coincides with the center of the image. The second is that the iron bacteria sludge is positioned in the image so that the deviation of the center of the iron bacteria sludge from the center of the image is within, for example, 10% of the maximum width of the image (for example, the length of the diagonal of the image).

[0039] A measurement standard is a reference object used to measure the size of an object in order to calculate the area of ​​the region where iron bacteria sludge (the material to be removed) is spread on the tunnel wall (the structure to be inspected). The measurement standard can be, for example, a ruler, or an object such as a rod or block whose size information is known. When using these objects as measurement standards, the measurement standard should be placed near the iron bacteria sludge and an image should be taken. Alternatively, the measurement standard may be a predetermined location already included in the tunnel. Specifically, a predetermined location can be, for example, equipment such as rails laid on the ground inside the tunnel, or cracks or leaks on the tunnel wall. The location information of the predetermined location, preferably including height information, is known from the tunnel's design information, inspection information, etc. Therefore, an image should be taken that includes the iron bacteria sludge and at least a part of the predetermined location. The type and location information of the measurement standard are stored, for example, in the measurement standard information database in the storage unit 215 of the information processing device 100, linked to the design information, inspection information, etc.

[0040] Iron bacteria sludge often forms in areas where water leaks from cracks or other openings in the tunnel walls and spreads downwards. In other words, iron bacteria sludge is often formed below the source of the water leak. Therefore, the designated location can be the water leak located above the iron bacteria sludge, or the water leak located above the iron bacteria sludge and closest to it. This eliminates the need to place another object as a measurement reference, and the area of ​​the spread iron bacteria sludge can be calculated based on the inspection information simply by taking an image that includes both the iron bacteria sludge and the water leak.

[0041] Figure 3 shows an example of an image. Image 401A is a still image of the inside of a tunnel, where rails 406 are laid on the ground 407 inside the tunnel. On the tunnel wall 405, iron bacteria sludge 403 has formed below the water leakage point 402. Image 401A includes the entire iron bacteria sludge 403 and the water leakage point 402. It is preferable that Image 401A includes the entire iron bacteria sludge 403. This allows for accurate calculation of the area of ​​the entire region of iron bacteria sludge 403 in the tunnel. The method of taking Image 401A is not particularly limited, but from the viewpoint of accurately calculating the area of ​​the region of iron bacteria sludge 403, it is preferable that the image is taken from the front of the iron bacteria sludge, as shown in Figure 3.

[0042] [Image Processing Department] The image processing unit 203 extracts the entire area of ​​the iron bacteria sludge and the measurement reference area from the image acquired by the image acquisition unit 202 to generate an extracted image. In the image, an area refers to a set of multiple consecutive pixels.

[0043] There are no particular limitations on the method for extracting the regions of iron bacteria sludge and the measurement standard regions; generally known image processing methods and methods combining multiple known image processing methods can be employed. Specifically, examples include methods for extracting both regions using thresholding based on color information, methods for detecting the contours of both regions from the image and extracting both regions based on those contours, methods for extracting both regions using a machine learning model, and methods combining these. Below, as an example, a method for extracting both regions using thresholding based on color information will be described.

[0044] Since iron bacteria sludge generally has a distinctive color different from the background color, such as reddish-brown, a first specific color region, preferably a reddish-brown region, corresponding to the area of ​​iron bacteria sludge can be extracted based on this color.

[0045] A first method for extracting a specific color region, preferably a brownish-red region, is as follows: First, the image is extracted from the RGB space information as YCbCr and L * a * b * The information is converted into a color space that can be separated into luminance components (brightness components) and color difference components (hue components). Then, the numerical range of the color, preferably the hue, of the iron bacteria sludge is set as the first color range, and threshold processing is performed on whether or not the color information of a pixel is included in the first color range. Specifically, the region having pixels whose color information is included in the first color range is determined to be the first specific color region, and the region having pixels that are not included in the first color range is determined to be a region other than the first specific color region. In this way, the first specific color region is extracted.

[0046] If the color of the measurement standard is a distinctive color different from the background color, such as black in the case of cracks or leaks, the numerical range of the color of the measurement standard, preferably the hue, can be set as a second color range, and threshold processing can be performed as described above, depending on whether the color information of the pixels is included in the second color range. In this way, the area of ​​the measurement standard can be extracted as a second specific color range. Note that the image includes part or all of the measurement standard. The image does not need to include the entire measurement standard, but it is sufficient if it includes at least a part of it, as long as it can serve as a clear standard for calculating the actual area of ​​the region where iron bacteria sludge is spread in the tunnel.

[0047] The settings for the first and second color ranges are not particularly limited; the user may manually input the color ranges, or they may be pre-registered in the memory unit. Alternatively, the color ranges may be set by the user or within a pre-set numerical range based on the color information of pixels in a region selected by the user on the image. The information of the first and second color ranges used in image processing may be linked to image information and extracted image information, etc., and stored in the memory unit 215 in a database.

[0048] In the case of thresholding based on color information, areas that do not actually fall under the iron bacteria sludge and measurement standard areas may be extracted as first and second specific color areas as noise. Methods to reduce such noise include, for example, setting a lower limit for the number of pixels that make up both areas and extracting only areas with a certain number of pixels, or extracting only the areas with the most pixels as the first and second specific color areas, respectively.

[0049] Furthermore, the image processing performed by the image processing unit 203 may include, in addition to the above-mentioned processing, generally known processing such as smoothing, from the viewpoint of accurately extracting the entire area of ​​the iron bacteria sludge and the area of ​​the measurement standard.

[0050] The image processing unit 203 generates an extracted image that reflects the extraction results of the entire iron bacteria sludge region and the measurement reference region. Specifically, for example, from the image 401A in Figure 3 described above, the entire iron bacteria sludge region and the measurement reference region are extracted, and a binarized image 401B, as shown in Figure 4, is generated as the extracted image. The extracted image is not limited to a binarized image, but may also be a superimposed image of the original image and a masked image in which regions other than both regions are masked. The extracted image may be displayed on the display unit 117 via the display processing unit 206.

[0051] [Area calculation part] The area calculation unit 204 calculates the area of ​​the entire region of iron bacteria sludge in the tunnel based on the positional information of the measurement reference in the tunnel and the extracted image.

[0052] Specifically, as shown in Figure 3, for example, the height H1 of the water leakage point 402 in the tunnel is known from the tunnel inspection information. In addition, the number of pixels and pixel positions that make up both regions in the binarized image 401B in Figure 4 are also known. Therefore, based on the height H1 of the water leakage point 402 and the pixel information of both regions in the binarized image 401B in Figure 4, the area of ​​the entire region of iron bacteria sludge 403 in the tunnel can be calculated.

[0053] [Required quantity calculation unit, display processing unit, and transmission unit] The required amount calculation unit 205 calculates the required amount of removal agent needed to remove iron bacteria sludge in the tunnel, based on the standard amount obtained by the standard amount acquisition unit 201 and the area of ​​the entire iron bacteria sludge region in the tunnel calculated by the area calculation unit 204. The calculated required amount is stored in the storage unit 215 as needed.

[0054] The display processing unit 206 displays the calculated required amount on the display unit 117.

[0055] The transmitting unit 207 transmits order information to the supplier of the removal agent via the communication unit 115, based on the required amount of removal agent and the supplier information of the removal agent stored in the storage unit 215. By providing the transmitting unit 207, automatic ordering of the removal agent becomes possible, leading to a reduction in the user's workload. The supplier refers to the manufacturer, distributor, importer, etc., of the removal agent. The order information is stored in the storage unit 215, linked to information acquired, generated, or output by the various processes described above as needed.

[0056] <Information Processing Methods> As shown in Figure 5, an example of the information processing method according to the embodiment comprises a reference quantity acquisition step S1, an image acquisition step S2, an image processing step S3, an area calculation step S4, and a required quantity calculation step S5. Furthermore, this information processing method comprises at least one of a required quantity display step S6 and an ordering step S7. In Figure 5, a solid arrow indicates that the information processing method comprises a required quantity display step S6 but not an ordering step S7, a dashed arrow indicates that it comprises both a required quantity display step S6 and an ordering step S7, and a dotted arrow indicates that it does not comprise a required quantity display step S6 but does comprise an ordering step S7. According to this information processing method, the amount of material to be removed and the amount of removal agent required to remove the material can be calculated with high accuracy.

[0057] The standard quantity acquisition step S1 is a step in which the amount of removal agent required to remove the target material per unit area is obtained as a standard quantity, and this is achieved, for example, by the standard quantity acquisition unit 201 described above.

[0058] Image acquisition step S2 is a step in which an image is acquired of the entire object to be removed and the measurement reference in the structure to be inspected, and is realized, for example, by the image acquisition unit 202 described above.

[0059] Image processing step S3 is a step in which the entire area of ​​the object to be removed and the measurement reference area are extracted from the image to generate an extracted image, which is realized, for example, by the image processing unit 203 described above.

[0060] The area calculation step S4 is a step in which the area of ​​the entire region of the object to be removed in the structure to be inspected is calculated based on the positional information of the measurement reference in the structure to be inspected and the extracted image, and is implemented, for example, by the area calculation unit 204 described above.

[0061] The required amount calculation step S5 is a step in which the amount of removal agent necessary to remove the object to be removed from the structure under inspection is calculated as the required amount based on the standard amount and the area of ​​the entire region of the object to be removed from the structure under inspection, and is realized, for example, by the required amount calculation unit 205 described above.

[0062] The required quantity display step S6 is a step in which the calculated required quantity is displayed on the display unit 117, and is realized, for example, by the display processing unit 206 described above.

[0063] The ordering process S7 is a process of sending ordering information to the supplier of the removal agent based on the required amount of the removal agent, and is realized, for example, by the transmission unit 207 described above.

[0064] <Computer programs and recording media> At least a portion of each step of the above-described information processing method is computerized. That is, an example of a computer program according to this disclosure is a program that causes a computer to execute at least the steps of the above-described process, from the reference quantity acquisition step S1 to the required quantity display step S6. In addition to these steps, the program may also be configured to execute the order step S7 as needed. Another example of a computer program according to this disclosure is a program that causes a computer to execute at least the steps of the above-described process, from the reference quantity acquisition step S1 to the required quantity calculation step S5 and the order step S7. These programs are stored in, for example, the storage unit 215 and can be executed by the CPU 110. Furthermore, the program is not limited to being stored in the storage unit 215, but can also be recorded on various well-known computer-readable recording media, such as an external hard disk, optical disk media, or magnetic tape media. The program can then be executed by connecting such a recording media to the information processing device 100 or by attaching it to a reading unit (not shown) and reading the program.
