Description

The technology disclosed in this specification relates to an examination support apparatus.

2. Description of the Related Art High-strength bolt joints are widely used as a method for joining two steel frame members (for example, an end member and a central member of a beam) that constitute structures such as buildings and civil engineering structures. High-strength bolt joining is a method of joining members using frictional force by tightening high-strength bolts (high-tension bolts) with high tensile strength with a predetermined force.

When joining high-strength bolts, a plate member (splice plate) is placed across the two steel frame members to be joined, and high-strength bolts are inserted into each of the multiple holes formed in each steel frame member and plate member. A nut is screwed onto each high-strength bolt so that it is inserted and the washer is sandwiched between each nut and the plate member. After the primary tightening of the nut is performed, the high-strength bolt, the nut, the washer and the plate member are marked with a linear mark, and then the final tightening of the nut is performed. By fully tightening the nut, the position of the mark on the nut is shifted from the position of the mark on the high-strength bolt, washer and plate member by the rotation angle of the nut.

After the final tightening of the nut, a tightening check of the high-strength bolt is performed. In the conventional tightening inspection, the inspector visually identifies the rotation angle of each nut due to final tightening based on the positions of the marks attached to the high-strength bolts, nuts, washers, and plate members. It is determined whether or not it is within the acceptable range (see, for example, Patent Literature 1). The acceptable range is, for example, a range of ±30 degrees from the average rotation angle of each nut. If the rotation angle of the nut is larger than the acceptable range, the high-strength bolt is replaced, and if the rotation angle of the nut is smaller than the acceptable range, it is tightened again. .

Here, the contents of the high-strength bolt tightening inspection at the joints of the beams of the steel-framed building will be described. When joining steel beams with high-strength bolts, a plate member (splice plate) is placed across the two steel beams to be joined, and high-strength bolts are applied to each of the plurality of holes formed in each steel beam and plate member. A nut is screwed onto each high-strength bolt such that the bolt is inserted and the washer is sandwiched between each nut and the plate member. After the primary tightening of the nut is performed, the high-strength bolt, the nut, the washer and the plate member are marked with a linear mark, and then the final tightening of the nut is performed. By fully tightening the nut, the position of the mark on the nut is shifted from the position of the mark on the high-strength bolt, washer and plate member by the rotation angle of the nut.

After final tightening of the nut, a high-strength bolt tightening test is performed. In this tightening inspection, the rotation angle of each nut due to final tightening is specified, and it is determined whether or not the rotation angle of each nut is within the acceptable range. The acceptable range is, for example, a range of ±30 degrees from the average rotation angle of each nut. If the rotation angle of the nut is larger than the acceptable range, the high-strength bolt is replaced, and if the rotation angle of the nut is smaller than the acceptable range, it is tightened again. .

In this embodiment, the steel beams are made of H-shaped steel. Therefore, the item display field HC1 of the inspection screen HS displays three items: "upper flange", "lower flange", and "web". The control unit 210 of the examination support apparatus 200 activates the imaging unit 250 in response to receiving a tap (selection operation) on one item (for example, “web”) displayed in the item display field HC1. , a message is displayed on the display unit 240 to prompt the imaging unit 250 to image the joint of the web of the steel beam. The inspector takes an image of the web joint of the steel beam using the imaging unit 250 . As a result, a target image PH0 showing the joint portion is acquired.

FIG. 7 is an explanatory diagram showing an example of the target image PH0. FIG. 8 is an explanatory diagram showing an enlarged part of the target image PH0 (part near one high-strength bolt BO). As shown in FIGS. 7 and 8, the target image PH0 shows each member that constitutes the joints of the steel beams. Specifically, the target image PH0 includes two steel beams SG to be spliced, a plate member (splice plate) PL arranged on the web of the steel beams SG across the two steel beams SG, and each A high-strength bolt BO inserted into each of a plurality of holes formed in the steel beam SG and the plate member PL, a nut NU screwed to each high-strength bolt BO, and between each nut NU and the plate member PL The washer WA sandwiched between is shown. In the following description, a combination of one high-strength bolt BO, one nut NU, and one washer WA that are screwed together is called a fastening unit. The joint shown in the target image PH0 shown in FIG. 7 includes 16 fastening units. Furthermore, the target image PH0 includes marks MA attached to each member (a mark MAb attached to the high-strength bolt BO, a mark MAn attached to the nut NU, a mark MAw attached to the washer WA, and a mark MAw attached to the plate member A mark MAp) attached to the PL is shown. Since the target image PH0 is an image after the nut has been fully tightened, the positions of the marks MAn attached to the nut correspond to the mark MAb attached to the high-strength bolt, the mark MAw attached to the washer WA, and the plate member PL. It is shifted by the rotation angle of the nut NU from the position of the attached mark MAp. The mark MAp attached to the plate member PL, the mark MAb attached to the high-strength bolt BO, or the mark MAw attached to the washer WA are examples of first marks, and the mark MAn attached to the nut is an example of a second mark.

After the target image PH0 is obtained, the control unit 210 of the inspection support apparatus 200 analyzes the target image PH0 to identify the region of the high-strength bolt BO in the target image PH0 and the mark MAp attached to the plate member PL. A region, a region of a mark MAn made on the nut NU, a region of a mark MAb made on the high-strength bolt BO, and a region of a mark MAw made on the washer WA are extracted. Extraction of each of these regions can be realized by using a known image recognition technique such as statistical pattern recognition based on image feature values. Artificial intelligence (AI) may be used for image recognition. In this way, image recognition accuracy can be improved. In addition, as described above, in response to receiving a tap (selection operation) on the beam icon AG2 displayed at the selected inspection position KL1, the control unit 210 controls the joint portion of the beam corresponding to the selected icon. structure data D508 (for example, information specifying the diameter, number, arrangement, etc. of the high-strength bolt BO). This structure data D508 may be used for image recognition. In this way, the structure data D508 for the joint portion of the beam at the selected inspection position KL1 can be reliably associated, and by using the structure data D508, the processing time can be reduced while improving the image recognition accuracy. can be shortened.

In addition, the control unit 210 of the inspection support apparatus 200 controls the marks MAp, MAb attached to the plate member PL, the high-strength bolt BO, and the washer WA for each fastening unit based on the regions extracted from the target image PH0. , MAw and the position of the mark MAn on the nut NU about the center point P0 of the high-strength bolt BO (hereinafter referred to as "nut rotation angle θ1"). The position of the center point P0 of the high-strength bolt BO can be obtained from the extracted region of the high-strength bolt BO. For example, the centroid of the area of the high-strength bolt BO can be obtained and the centroid can be set as the center point P0. Similarly, the positions of the respective marks MAp, MAb, MAw and MAn can also be obtained from the extracted areas of the respective marks MAp, MAb, MAw and MAn. For example, the centroids of the regions of the marks MAp, MAb, MAw, and MAn can be obtained, and the centroids can be used as the positions of the marks MAp, MAb, MAw, and MAn.

In addition, when a plurality of fastening units are included in the joint, from the target image PH0, the area of the high-strength bolt BO, the area of the mark MAp attached to the plate member PL, the mark MAb attached to the high-strength bolt BO , a plurality of regions of the mark MAw on the washer WA, and a plurality of regions of the mark MAn on the nut NU are extracted. The control unit 210 of the inspection support device 200 groups the plurality of extracted regions for each fastening unit, and specifies the nut rotation angle θ1 based on the regions belonging to the same group. As a grouping method, for example, a method of specifying four marks MA closest to the center point P0 of the high-strength bolt BO as marks MAp, MAb, MAw, and MAn belonging to the same group can be adopted. More specifically, the mark MA closest to the center point P0 of the high-strength bolt BO is specified as the mark MAb attached to the high-strength bolt BO, and the mark MA second closest to the center point P0 of the high-strength bolt BO is specified as the mark MAn attached to the nut NU. The third closest mark MA is specified as the mark MAw on the washer WA, and the fourth closest mark MA is specified as the mark MAp on the plate member PL. That is, the nut rotation angle θ1 is determined by the position of the mark MAn attached to the nut NU, which is the second closest mark MA from the center point P0 of one high-strength bolt BO, among the plurality of marks MA, and the position of the mark MAn attached to the nut NU. A mark MAb attached to the high-strength bolt BO, a mark MAw attached to the washer WA, and a mark MAp attached to the plate member PL, which are the first, third, and fourth marks MA from the center point P0 of the force bolt BO. at least one location;

Next, the control unit 210 of the inspection support device 200 calculates the average value of the nut rotation angles θ1 specified for each fastening unit. More specifically, control unit 210 totals the values of nut rotation angle θ1 for each fastening unit and divides the total value by the number of fastening units to calculate the average value of nut rotation angle θ1. Control unit 210 identifies the number of fastening units (that is, the number of high-strength bolts BO, washers WA and/or nuts NU) included in the joint by analyzing target image PH0. Alternatively, the control unit 210 uses the structural data D508 (for example, information specifying the diameter, number, arrangement, etc. of the high-strength bolts BO) for the beam joint corresponding to the above-described icon, The number of fastening units (that is, the number of high-strength bolts BO) may be specified.

Next, the control unit 210 of the inspection support device 200 sets a pass range based on the average value of the nut rotation angles θ1 for each fastening unit. More specifically, control unit 210 sets a range of ±30 degrees from the average value of nut rotation angles θ1 for each fastening unit as the acceptable range. In the example shown in FIG. 9, the average value of the nut rotation angle θ1 is 39.4 degrees, so the acceptable range is set to the range of 9.4 degrees to 69.4 degrees.

Further, the control unit 210 of the inspection support device 200 determines whether or not the nut rotation angle θ1 of each fastening unit is within the set acceptable range. In the example shown in FIG. 9, since the nut rotation angle θ1 for one fastening unit is 9 degrees, the nut rotation angle θ1 for that fastening unit is not within the acceptable range. The nut rotation angles θ1 of other fastening units are all within the acceptable range.

After that, the control unit 210 of the inspection support apparatus 200 generates an inspection image PH1 used for inspecting the joint. FIG. 9 is an explanatory diagram showing an example of the inspection image PH1. Based on the target image PH0, the inspection image PH1 includes an angle image ANi indicating the value of the nut rotation angle θ1 for each fastening unit, a number image NPi indicating the number of fastening units included in the joint, and an average value image AVi indicating the average value of the nut rotation angle θ1 of the joint unit, an acceptable range image PAi indicating the acceptable range, and a judgment image JUi indicating whether the nut rotation angle θ1 of each fastening unit is within the acceptable range; is superimposed on the image. In the example of FIG. 9, a hatched image displayed at the position of the fastening unit where the nut rotation angle θ1 is not within the acceptable range is used as the determination image JUi. As the judgment image JUi, another image (for example, a hatched image displayed at the position of a fastening unit whose nut rotation angle θ1 is within the acceptable range, or a fastening unit whose nut rotation angle θ1 is within the acceptable range and within the acceptable range A different display mode (for example, a different color or shape) may be used for a fastening unit that is not in the standard. The control unit 210 causes the storage unit 220 to store the image data of the inspection image PH1 as the image data D507 of the map information data D302 corresponding to the selected inspection position KL1. Note that the control unit 210 may cause the storage unit 220 to store the target image PH0 as the image data D507 in addition to the inspection image PH1.

The control unit 210 of the inspection support apparatus 200 causes the display unit 240 to display the generated inspection image PH1. Specifically, the inspection image PH1 is displayed in the image display field HP1 in the inspection screen HS displayed on the display unit 240. FIG. FIG. 10 is an explanatory diagram showing an example of the inspection screen HS after the first inspection of a joint is performed. In the example of FIG. 10, an inspection image PH1 (or a thumbnail image thereof) of the web at a joint is displayed in the image display field HP1 of the inspection screen HS. Note that when a thumbnail image is displayed in the image display field HP1, the inspection image PH1 corresponding to the thumbnail image is displayed on the display unit 240 in response to receiving a tap on the displayed thumbnail image. may be
