Description

  The present invention relates to a technique for creating a survey map of remains in excavation survey.

  Remains are remnants that provide clues to know the shape and structure of old cities and buildings. And if there are remains at the place where civil engineering work or construction work is performed, based on the request by the prescribed law such as the Cultural Properties Protection Act, make a record about the remains before they are destroyed by these works Records must be kept.

  The records related to the remains include cross-sections and plan views of the remains measured from the cross-section and plane directions. The top line, bottom line, subdivision line, topsoil line, position information, etc. are included in the drawing. Record the details of the remains.

  Such excavation excavations are called emergency excavations, and the period allocated to excavations is very short for the convenience of the construction owner, so it is necessary to create an accurate survey of the remains in a short period of time. Under such circumstances, several proposals have been made regarding techniques for accurately excavating remains in a short period of time.

  For example, in Patent Document 1, it is easy to create a rough map of the actual remains at the site of the ruins, and a quick and accurate compilation of the actual map of the remains from the rough map of the remains at the site away from the remains. In order to concentrate on the surveying of the points, the measured values measured by the light wave surveying instrument are sent to the remains measurement support system, and the remains measurement support system converts the measured values into the coordinate values of the public coordinate system and converts the coordinate value data into Create and create a rough map of the actual structure map from the coordinate data and store it in the rough map file of the actual structure map. Scanned with a scanner, and sent the remains measured map rough map data and the remains measured map rough map corrected data to the remains measured map editing system, the remains measured map editing system based on the remains measured map rough map corrected The crude FIG editing on the screen to create the ruins measured map, how to take a check by sending the remains actual view ruins site has been proposed.

  However, the method of creating the remains sectional view 180 and the remains plan diagram 190 for each remains has the same procedure, and if the method applied to one remains 210 is applied to other remains, all shown in FIG. A cross-sectional view 180 and a plan view 190 of the remains can be created.

  Therefore, in the following, the excavation and excavation method 100 will be described in detail with reference to FIGS. 3 to 17, but the excavation and excavation method for the remains 210 located in the center of FIG. 2 will be described. FIG. 3 is a flowchart showing the flow of the remains excavation survey method 100.

  As shown in FIG. 3, the remains excavation survey method 100 is the excavation process (S 10), the white paint application process (S 20), and the photograph for the creation of the remains cross-sectional view 180 that is the actual remains of the remains 210 observed from the cross-sectional direction. Shooting step (S30), first image data transmission step (S40), first image data receiving step (S40), ortho image generation step (S50), remains measurement actual drawing generation step (S60), second image data It includes a transmission step (S70), a second image data reception step (S70), a remains measurement actual drawing confirmation step (S80), and a third image data transmission step (S90, S100).

  In addition, the remains excavation survey method 100 includes the excavation process (S110), the white paint application process (S120), and the photography process (S130) with respect to the creation of the remains plan 190, which is an actual measurement figure of the remains 210 observed from directly above. ), First image data transmission step (S140), first image data reception step (S140), ortho image generation step (S150), remains actual measurement drawing generation step (S160), and second image data transmission step (S170). ), A second image data receiving step (S170), a remains actual figure confirmation step (S180), and a third image data transmitting step (S190, S200).

  In the excavation process of S10, as shown in FIG. 4, the cross section of the remains 210 that is the object of creation of the remains actual measurement map 180 is excavated. At this time, it is only necessary to expose the cross section of the remains 210 to be created of the remains measurement map 180, and there are no particular limitations on the excavation tool, the excavation technique, and the like. A portion indicated by a dotted line in FIG. 4 is a boundary line 220 of a portion where it is desired to distinguish one portion from another portion in the remains measurement actual drawing 180. The boundary line 220 includes what is called an upper end line, a lower end line, a layer line, a topsoil line, and a digging line. In addition, the boundary line 220 is not drawn in the cross section of the remains 210 in S10, and is drawn with a dotted line for convenience.

  In the white paint application process of S20, as shown in FIG. 5, the boundary of the portion to be distinguished and indicated on the actual structure map 180 in the cross section of the target structure 210 to be created of the actual structure map 180 is bounded by the white paint. Fill in line 220. The boundary line 220 needs to be white because of image processing in the subsequent process, but may be substantially white and may not be pure white. In addition, the boundary line 220 indicates the boundary of a portion that is desired to be distinguished from one part and the other part in the remains measurement actual map 180, and includes an upper end line, a lower end line, a subdivision line, a topsoil line, a digging Including what is called a direction line.

  In the photography step of S30, as shown in FIG. 6, the digital camera 240 takes a photograph of the cross section of the remains 210 to be created of the remains measurement drawing 180 excavated in S10 and drawn with white lines in S20. . In the photography process, at least four photographs are taken. These four photographs are the front position of the cross section of the remains as shown in FIG. 6 (a), the overhead view of the cross section of the remains as shown in FIG. 6 (b), and the oblique view of the cross section of the remains as shown in FIG. 6 (c). One image is taken from the right position, as shown in FIG. As shown in FIGS. 4 and 5, these four photographs show the location information of the remains 210 such as the Konoe double 330 and the anti-aircraft index, and the range of enlargement such as the pin pole, Also make sure to check what you want to check.

  In the first image data transmission step of S40, the photographic data of the cross section of the remains 210 photographed in S30 from the field terminal 140 to the remains actual measurement drawing creation device 150 via the communication network 130, the coordinates of a predetermined position in the photograph. The data 250 for creating a structure actual measurement map including the data and the identification information of the digital camera 240 that performed the photographing is transmitted. The on-site terminal 140 is assumed to be a portable information terminal or a personal computer having a communication function, but the form is not particularly limited as long as the function defined in the present invention is exhibited.

  In the first image data receiving step of S40, the remains actual measurement map creation device 150 installed in the work place 120 for creating the remains actual measurement map is transmitted for the remains actual measurement map creation data transmitted in the first image data transmission step. 250 is received. In addition, although the remains structure actual drawing preparation apparatus 150 assumes information processing apparatuses, such as a personal computer provided with the communication function, as long as the function prescribed | regulated by this invention is exhibited, a form will not be specifically limited. Further, in the first image data transmission step and the first image data reception step, it is possible to directly transmit / receive the remains actual measurement map creation data 250 between the on-site terminal 140 and the remains actual measurement map creation device 150. A configuration may be adopted in which the data 250 for creating the actual structure map is exchanged via a storage installed on the network 130.

In the ortho image generation process of S50, the remains actual measurement map creation device 150 creates an ortho image 160 of the cross section of the remains 210 to be created of the remains actual measurement map 180 based on the remains actual measurement map creation data 250 received in S40. Generate. The ortho image 160 includes position information of the survey target remains 210. For example, as shown in FIG. 5, the ortho image 160 generated in the ortho image generation process has no distortion in the shape of the image and the position is correctly arranged. It is possible to measure accurately. In the information processing for generating the ortho image 160, as an example, software such as a three-dimensional photograph plotting measurement system Kuraves-G ² (Kurashiki Boseki Co., Ltd.), Adobe Photoshop (Adobe Systems Co., Ltd.) is used.

  In the actual structure map generation process of S60, the actual structure map creation device 150 generates the actual structure map data 180 based on the ortho image data 160 generated in S50. As a specific process, a two-gradation process is applied to the ortho image data 160 as shown in FIG. 5 by applying a predetermined boundary threshold value to generate intermediate image data 270 as shown in FIG. As the next step, the intermediate image data 270 shown in FIG. 7 is subjected to black and white reversal processing to generate image data 280 as shown in FIG. Finally, when the position information of the survey target remains 210 is combined with the image data of FIG. 8, the actual structure map data 180 including the position information of the survey target remains 210 as shown in FIG. 9 is generated.

  In the second image data transmission step of S 70, the actual structure map data 180 generated in S 60 is transmitted from the actual structure map creating apparatus 150 to the site terminal 140 via the communication network 130.

  In the second image data receiving step of S70, the site terminal 140 installed in the site 110 of the remains excavation survey receives the remains measured map data 180 transmitted in the second image data transmission step. In the second image data transmission step and the second image data reception step, the actual structure map data 180 may be directly exchanged between the site terminal 140 and the actual structure map creation device 150, but the communication network 130. A configuration may be adopted in which the historical measurement map data 180 is exchanged via the storage installed above.

The cross-section of the remains 210 is compared, and it is visually confirmed whether or not they match.

  Here, when the coincidence between the two cannot be confirmed in S80 (Yes in S90), the procedure proceeds to S100. On the other hand, if the coincidence between the two can be confirmed in S80 (No in S90), the procedure proceeds to S110, and the process moves to the work of creating the actual structure map of the remains 210 plane.

  In the third image data transmission step of S100, the remains measured map data 180 corrected on the site terminal 140 or the printed remains measured map data 180 modified with the scanner is created. The remaining actual measurement map correction data 310 is transmitted from the site terminal 140 to the remains actual measurement map creating device 150 via the communication network 130 together with the correction instruction. In the actual structure map creating apparatus 150, the actual structure map 180 is completed based on the received actual structure map correction data 310 and the correction instruction.

  In the excavation process of S110, as shown in FIG. 10, the remains 210 plane that is the object of creation of the remains actual measurement map 190 is excavated. At this time, it suffices if the remains 210 plane to be created of the remains actual measurement map 190 is exposed, and the excavation tool, the excavation technique and the like are not particularly limited. A portion indicated by a dotted line in FIG. 10 is a boundary line 230 of a portion in which one portion and another portion are desired to be distinguished from each other in the historical measurement diagram 190. The boundary line 230 is called an upper end line, a lower end line, a division line, a topsoil line, and a digging line. Further, the boundary line 230 is not drawn on the plane of the remains 210 in S110, and a dotted line is attached for convenience of explanation.

  In the white paint application step of S120, as shown in FIG. 11, the white paint is used as the boundary of the portion that is desired to be distinguished and indicated on the remains actual measurement map 190 on the surface of the remains 210 to be created. Fill in line 230. The boundary line 230 needs to be white because of image processing in a later process, but may be substantially white and may not be pure white. In addition, the boundary line 230 indicates a boundary of a part that is desired to be distinguished from one part and the other part in the actual measurement map 190, and includes an upper end line, a lower end line, a subdivision line, a topsoil line, a digging Including what is called a direction line.

  In the photo-taking process of S130, as shown in FIG. 11, the digital camera 240 takes a photo of the remains 210 plane that is the object of creation of the remains-measurement drawing 190 excavated in S110 and drawn with white lines in S120. . In the photography process, at least four photographs are taken. These four photographs are as shown in FIG. 12 (a), the position just above the remains plane (plane overhead view position), the remains front view position as shown in FIG. 12 (b), and FIG. 12 (c). Then, one image is taken from the oblique right position of the remains plane, and from the oblique left position of the remains plane as shown in FIG. As shown in FIG. 10 and FIG. 11, the photo shows the position information of the remains such as the Konoe double 330 and anti-aircraft index, the range of the image enlargement such as a pin pole, and the length is confirmed at the time of analysis. Make things appear.

  As shown in FIG. 13, the shooting directions shown in FIGS. 12A to 12D are determined by the camera stand device 200. The camera stand device 200 is a dedicated instrument that determines the photographing direction of a photograph for creating the remains plan 190, and is a position directly above the remains plane (plane overhead view position) in FIG. 12 (a), as shown in FIG. 12 (b). It is possible to uniquely determine the front view position of the remains, the oblique right side position of the remains cutting plane of FIG. 12C, and the oblique left position of the remains plane of FIG.

  The camera stand device 200 includes a support base installed on the ground of the photographing site, and a long support column that is set up by the support base and to which the camera is attached. In contrast, the camera can be tilted in the left-right direction and the forward direction, and can be rotated in the circumferential direction, and the camera can be raised and lowered on the upper end side of the support column, and the elevation angle of the camera can be adjusted. A camera stand device that enables the support base to be provided on the base body so as to cover the plate-like base body, a spherical support member fixed on the base body, and the spherical support member. The cylindrical case body comprises at least an integrated cylindrical case body, and a central recess for holding the pillar in a vertically extending state on the upper surface of the tubular case body, and the state where the pillar is inclined leftward. Hold the left inclined holding dent and A right-tilt holding dent that holds the column tilted rightward, a front-tilt holding dent that holds the column tilted forward, a central dent, a left-tilt holding dent, and a right-tilt Provided with an opening made of a passage for movement of the support column to the holding recess and the forward inclined holding recess, the left inclined holding recess, the right inclined holding recess and the forward inclined holding recess, The column is held so that the horizontal and forward inclination angles of the column are substantially the same, and a fitting concave member whose inner wall is substantially hemispherical is fixed to the lower end of the column. By fitting the fitting recess material into the spherical support member of the support base through the opening of the cylindrical case body in a rotatable and detachable manner, the support column is attached to the support base. Rotate and wear Furthermore, when the support column is lifted upward in a state where the support column is fitted to the central recess of the cylindrical case body, the support column is locked to the lower surface of the edge of the central recess. When the support column is lifted upward by preventing the fitting recess material from slipping out of the spherical head and by tilting the support column so that it does not fit into the center recess, the central recess A stopper ring that allows the fitting recess material to come out of the spherical head without being locked to the lower surface of the edge of the rim is fixed. The camera stand device 200 is equivalent to the camera stand device according to Japanese Patent No. 4446256.

  Then, as shown in FIG. 14 (a), the camera stand device 200 tilts the support column to the remains 210 side, directs the digital camera 240 directly below, and takes a picture from above the remains (FIG. 12 (a)). It is possible to take a photograph from the position of the overhead view of the remains (FIG. 12B) by pulling the column to the near side and making it vertical.

In the first image data transmission process and the first image data reception process, the remains actual map creation data 260 may be directly exchanged between the site terminal 140 and the remains actual map creation apparatus 150. A configuration may also be adopted in which the data for creating a historical measurement map 260 is exchanged via a storage installed on the network 130.

In the orthoimage generation process of S150, the remains actual measurement map creation device 150 creates the orthoimage 170 of the remains 210 plane, which is the creation target of the remains actual measurement map 190, based on the data 260 for creating the remains actual measurement received in S140.

For example, as shown in FIG. 11, the ortho image 170 generated in the ortho image generation process has no distortion in the shape of the image, and the position is correctly arranged. It is possible to measure accurately. The information processing for generating the ortho image 170 uses, for example, software such as a three-dimensional photograph plotting measurement system Kuraves-G ² (Kurashiki Textile Co., Ltd.), Adobe Photoshop (Adobe Systems Co., Ltd.).

  In the historical structure actual map generation step of S160, the historical structure actual map creating apparatus 150 generates the historical structure actual map data 190 based on the ortho image data 170 generated in S150. As a specific process, a two-gradation process using a predetermined boundary threshold is applied to the ortho image data 170 as shown in FIG. 11 to generate intermediate image data 270 as shown in FIG. As the next step, the intermediate image data 270 in FIG. 15 is subjected to the black / white reversal process to generate image data 280 as shown in FIG. Finally, when the position information of the survey target remains 210 is combined with the image data 280 of FIG. 16, the remains measured map data 190 including the position information of the survey target remains 210 as shown in FIG. 17 is generated.

  In the second image data transmission step of S170, the remains measured map data 190 generated in S160 is transmitted from the remains measured map creation device 150 to the site terminal 140 via the communication network 130.

  In the second image data receiving step of S170, the site terminal 140 installed in the site 110 receives the remains measured map data 190 transmitted in the second image data transmitting step. In the second image data transmitting step and the second image data receiving step, the remains actual measured map data 190 may be directly exchanged between the site terminal 140 and the remains actual measured map creating apparatus 150, but the communication network 130. A configuration may be adopted in which the historical measurement map data 190 is exchanged via the storage installed above.

  In the step of confirming the actual structure map in S180, the actual structure map data 190 displayed on the site terminal 140 or the actual site map data 190 printed from the site terminal 140 and the creation target of the actual site map 190 shown in FIG. It is visually confirmed whether or not both are coincident with each other.

  Here, when the agreement between the two cannot be confirmed in S180 (Yes in S190), the procedure proceeds to S200. On the other hand, when the coincidence of both can be confirmed in S180 (No in S190), the work procedure of the remains excavation investigation method 100 ends.

In the third image data transmission process of S200, the remains actual structure map data 190 corrected on the site terminal 140 or the remains image correction data 320 that has been printed or modified is read and created by the scanner. The reconstructed actual structure map correction data 320 is transmitted from the on-site terminal 140 to the remaining actual structure map creating apparatus 150 via the communication network 130 together with a correction instruction. In the actual structure map creation apparatus 150, the actual structure map 190 is completed based on the received actual structure map correction data and the correction instruction. Thus, the work procedure of the remains excavation method 100 is completed.
(Summary)

  In the conventional remains excavation investigation method, as for the photograph of the remains 210 in a state where the white paint application process is not performed, the upper end line, the lower end line, the dividing line, etc. are manually written on the ortho image as appropriate in the work place 120. I was making a diagram. Therefore, the communication between the site 110 and the work place 120 is poor, and the draft of the remains actual measurement map has been revised frequently. As a result, the creation period of the remains actual measurement map has been extended, and the construction period has been increased accordingly.

  In the remains excavation investigation method 100, the intention of the site 110 is expressed by white line drawing in the white paint application process, and the creation work of the remains measurement drawings 180 and 190 is also automated. Therefore, the communication between the site 110 and the work place 120 is remarkably improved, and the frequency of correcting the remains measurement drawing draft is reduced. As a result, the creation period and the construction period of the remains measurement drawings 180 and 190 are shortened.

  In addition, the remains excavation method 100 can be expected to reduce costs associated with the remains excavation investigation because the number of workers is reduced as the work of creating the actual remains drawings 180 and 190 is automated.

  Although the embodiment of the present invention has been described in detail above, the present invention is not limited to the specific embodiment, and various modifications are possible within the scope of the gist of the present invention described in the claims.・ Change is possible.
