[0008] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all the drawings, like components are designated by like reference numerals, and the description thereof will be omitted as appropriate.

[0009] FIG. 1 is a diagram illustrating a usage environment of an information processing device 100 according to this embodiment. As an example, the information processing device 100 is used together with a wheeled drill jumbo 200 for drilling multiple holes for rock bolts in a tunnel face to reinforce the wall surface of the tunnel. The wheeled drill jumbo 200 includes a drilling machine 210 and a boom 230 equipped with a guide shell 220 on which the drilling machine 210 is mounted so as to be able to move forward and backward. These can be moved to a predetermined position by swinging the boom 230. The device with which the information processing device 100 is used is not limited to the wheeled drill jumbo 200, but may be any device that has the function of drilling holes for rock bolts. In the following description, the information processing device 100 will be described as being used together with the wheeled drill jumbo 200.

[0010] The wheeled drill jumbo 200 travels to a predetermined position inside the mine. Then, the boom 230 is swung to position the tip of the boom 230 at a position where a hole will be formed. The guide shell 220 then advances the drilling machine 210 to form the hole. The positions where these multiple holes will be formed are determined, for example, by a worker when creating a construction plan.

[0011] The information processing device 100 includes an acquisition unit 10, a generation unit 20, and an output unit 30. The acquisition unit 10 acquires an image including a hole for a rock bolt. The generation unit 20 processes the image acquired by the acquisition unit 10 to generate shape information, which is information relating to the shape of the hole. The output unit 30 outputs the shape information generated by the generation unit 20 in association with identification information of the corresponding hole. Each component will be described in detail below.

[0012] [Acquisition part 10] As described above, the acquisition unit 10 acquires an image including a hole for a lock bolt. The acquisition unit 10 acquires an image captured by an imaging device such as a general camera, for example.

[0013] Fig. 2 shows an example of an image acquired by the acquisition unit 10. Note that although the image shown in Fig. 2 includes only one hole 1 for a rock bolt, two or more holes 1 may be included in the image.

[0014] Furthermore, from the viewpoint of enabling the generating unit 20 (described later) to accurately generate shape information, the area showing the rock bolt holes 1 is preferably 5% or more of the entire image, more preferably 10% or more, and even more preferably 30% or more. Furthermore, from the viewpoint of accurately generating shape information, the image is preferably taken from an angle as perpendicular as possible to the face surface on which the rock bolt holes 1 are formed, and specifically, it is preferable that the image be taken at an angle of 60° to 120° to the face surface, and more preferably at an angle of 80° to 100°.

[0015] For example, the imaging device that captures the images is attached to the boom 230. It is preferable to capture images with the tip of the boom 230 in contact with the face surface. This allows images to be captured at an angle close to perpendicular to the face surface, and also makes it possible to maintain a constant distance between the imaging device and the hole when capturing each image.

[0016] An example of a state in which the tip of the boom 230 abuts against the face surface is the state after a hole has been drilled. For example, by capturing an image using an imaging device attached to the boom 230 as is after the hole has been drilled, it is possible to capture an image from a direction nearly perpendicular to the hole. However, since the imaging device may become dirty with dust or the like when drilling a hole, the imaging device may be detachable from the boom 230, removed when the hole is drilled, and attached when capturing an image after the hole has been drilled.

[0017] Furthermore, when there are multiple booms 230, the boom 230 for drilling the hole and the boom 230 equipped with the imaging device may be separate. In this case, images of the hole that has already been drilled can be captured in parallel with the work of drilling the hole.

[0018] Note that the method for capturing images is not limited to the above method, and for example, an operator may manually operate a camera to capture images.

[0019] [Generation section 20] The generating unit 20 generates shape information of the hole by processing the image acquired by the acquiring unit 10. Here, the shape information is information including at least one of the shape of the hole (circular, elliptical, polygonal, etc.), the diameter of the hole, and the angle of the hole orientation relative to the face surface.

[0020] An example of image processing in which the generation unit 20 generates a hole diameter as shape information of a hole is image processing in which the contour of the hole is extracted and the longest distance among the combinations of points on the extracted contour of the hole (the distance of line 2 in FIG. 3) is used as the hole diameter. Furthermore, from the viewpoint of improving the accuracy of the shape information, the image processing may include a step of binarizing the image acquired by the acquisition unit 10 into 0 and 1, as in the image shown in FIG. 3, and a step of inverting the binarized values. As a result, each pixel in the hole region in the image has a value of 1, and the area of ​​the hole can be easily calculated by adding up the values ​​of these pixels and multiplying the sum by a predetermined coefficient.

[0021] Furthermore, when generating shape information for multiple holes, the generation unit 20 may generate calculation information based on a specific hole and use the calculation information to generate shape information for the other holes. Here, the calculation information is, for example, information indicating the image and shape of the specific hole, and the shape information is, for example, shape information generated by the generation unit 20 or values ​​obtained by measuring the shape of the hole by a worker on-site. Using the calculation information including the image of the specific hole and information indicating the hole diameter, shape information for the other holes can be generated by comparing the image of the specific hole included in the calculation information with images of the other holes. For example, if the area of ​​the hole in the image of the other hole calculated by image processing is twice the area of ​​the hole in the image of the specific hole, the area of ​​the other holes can be estimated to be approximately twice the area of ​​the specific hole, and the diameter of the other holes can be estimated to be approximately √2 times the diameter of the specific hole. Furthermore, the calculation information preferably includes information indicating the positional relationship (e.g., distance) between the hole and the imaging device when the image of the specific hole was captured. This allows the shape of the other holes to be estimated based on the positional relationship between the hole and the imaging device when the image of each hole was captured. Furthermore, it is preferable that the image of the specific hole is captured under the same conditions as the images of the other holes. For example, it is preferable that both the image of the specific hole and the images of the other holes are captured by an imaging device attached to the boom 230 with the tip of the boom 230 in contact with the face surface.

[0022] [Output section 30] The output unit 30 outputs the shape information generated by the generation unit 20 in association with the hole identification information corresponding to the shape information. The hole identification information is, for example, a set of character strings, and is associated with each hole, for example, when planning the hole construction.

[0023] Fig. 4 is a diagram showing an example of information output by the output unit 30. As shown in Fig. 4, shape information may be output in the form of Table 3a in association with hole identification information. Furthermore, the output unit 30 may further associate the planned value of the hole diameter in the construction plan for each hole with the measured value of the hole diameter actually measured on-site after drilling, in association with the identification information for each hole, and output the same.

[0024] Furthermore, as shown in FIG. 5, in addition to displaying Table 3a shown in FIG. 4, a schematic diagram 3b of the face may also be displayed, and the identification information of each hole and the corresponding position information may be displayed on the schematic diagram 3b. This allows for intuitive understanding of which hole information each piece of shape information represents. Methods for associating position information with each hole include, for example, associating the position of the drilling machine 210 when each hole was drilled as the hole position information, associating the position of the imaging device when an image of each hole was captured as the hole position information, and associating the planned position when creating a construction plan for each hole as the hole position information. Furthermore, the display of position information is not limited to displaying the identification information of each hole on the schematic diagram 3b. For example, information such as coordinates may be displayed in Table 3a in association with the identification information of each hole.

[0025] In addition, the output unit 30 may display, for example, an image of a hole in association with the shape information.

[0026] The information processing device 100 can be realized by hardware such as a computer. Fig. 6 is a diagram showing an example of the hardware configuration of the information processing device 100. The information processing device 100 has a bus 1010, a processor 1020, a memory 1030, a storage device 1040, an input / output interface 1050, and a network interface 1060.

[0027] The bus 1010 is a data transmission path for transmitting and receiving data among the processor 1020, memory 1030, storage device 1040, input / output interface 1050, and network interface 1060. However, the method of connecting the processor 1020 and the like to each other is not limited to bus connection.

[0028] The processor 1020 is implemented by a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), or the like.

[0029] The memory 1030 is a main storage device realized by a RAM (Random Access Memory) or the like.

[0030] The storage device 1040 is an auxiliary storage device realized by an HDD (Hard Disk Drive), an SSD (Solid State Drive), a memory card, a ROM (Read Only Memory), or the like. The storage device 1040 stores program modules that realize each function of the information processing device 100. The processor 1020 loads each of these program modules into the memory 1030 and executes them, thereby realizing each function corresponding to the program module. The storage device 1040 also stores the above-mentioned hole identification information and position information.

[0031] The input / output interface 1050 is an interface for connecting the information processing device 100 to various input / output devices.

[0032] The network interface 1060 is an interface for connecting the information processing device 100 to a network. This network is, for example, a local area network (LAN) or a wide area network (WAN). The method for connecting the network interface 1060 to the network may be wireless connection or wired connection.

[0033] Next, the flow of information processing in this embodiment will be described below. Fig. 7 is a flowchart showing a first example of the flow of information processing in this embodiment.

[0034] First, a construction plan for holes for rock bolts is created (step S11). At this time, identification information and position information may be associated with each hole. Next, drilling of each hole included in the construction plan is completed (step S12). After that, an imaging device captures an image of each hole, and the acquisition unit 10 acquires the image (step S13). In step S13, for example, the boom 230 moves to a predetermined position for imaging the hole, and an image is captured by the imaging device attached to the boom 230. The boom 230 may be moved manually by an operator or automatically using position information associated with the identification information of each hole. Also, in step S12, the imaging device may not be attached to the boom 230, and the imaging device may be attached to the boom 230 in step S13. This prevents the imaging device from becoming contaminated by dust, etc.

[0035] Thereafter, the generating unit 20 processes the acquired image to generate shape information (step S14), and then the output unit 30 outputs the shape information of each hole in association with its identification information (step S15).

[0036] In step S15, position information of each hole may be further output. The position information of each hole may be obtained by associating the position information of the drilling machine 210 when the hole is drilled with the identification information of the hole, or by associating the position information of the imaging device with the identification information of the hole when an image of each hole is acquired.

[0037] Next, a second example of the flow of information processing in this embodiment will be described. Fig. 8 is a flowchart showing the second example of the flow of information processing in this embodiment. In the first example, images of each hole were acquired after the drilling of the holes was completed, but in the second example, images of holes that have been drilled up to that point are acquired even before the drilling of the holes is completed, and shape information is generated.

[0038] First, as in the first example, a construction plan for holes for rock bolts is created (step S21). Next, the holes are constructed (step S22). Next, the acquisition unit 10 acquires images of the holes drilled in step S22 (step S23). Then, the generation unit 20 processes the acquired images to generate shape information (step S24). However, in step S22, not all holes included in the construction plan need to be drilled; for example, only one hole may be drilled. In other words, steps S23 to S24 may be processes of acquiring an image including the hole each time a hole is drilled. Alternatively, they may be processes of acquiring an image including the hole for each of a predetermined number of holes after the holes have been drilled. When an image including the hole is acquired each time a hole is drilled, the image can be captured while the tip of the boom 230 is in contact with the face surface after the hole has been drilled, so the image can be captured from a direction nearly perpendicular to the hole.

[0039] Thereafter, it is determined whether or not all holes included in the construction plan have been drilled (step S25). If drilling has not been completed (step S25: No), steps S22 to S24 are performed again. When steps S22 to S24 are performed again, the images acquired and the shape information generated in the previous steps S22 to S24 may be used as calculation information. If construction has been completed (step S25: Yes), the output unit 30 outputs the shape information of each hole in association with its identification information, as in the first example (step S26).

[0040] As described above, the information processing device 100 according to this embodiment can facilitate management of information such as the shape of holes for lock bolts.

[0041] Although the embodiments of the present invention have been described above with reference to the drawings, these are merely examples of the present invention, and various other configurations can also be adopted. [Explanation of symbols]
