Description

The present invention supports an installation plan for a temporary scaffold used when constructing a new structure or repairing a structure (for example, a large structure such as a building, a tank, or a chimney, a large facility such as a chemical plant or a steelmaking plant). The present invention relates to a temporary scaffold plan support system.

Conventionally, the design of the temporary scaffold used when constructing a new structure is based on the design result of the structure and the process plan, and the design of the temporary scaffold used when repairing the structure is based on drawings and photographs. Based on the appearance state of the structure and the usage plan, the scaffold designer performs it by trial and error. For this reason, there is a problem that designing takes time and labor. In addition, since the accuracy of the scaffold design results is insufficient, problems such as temporary scaffolding interfering with the structure or not being in time for the necessary materials for temporary scaffolding occur when actually installing the temporary scaffolding. Was.
Therefore, first shape data indicating the three-dimensional shape of the structure (specifically, data created by the structure designer using three-dimensional CAD) and an additional structure (hereinafter referred to as the structure) used to construct the structure. The second shape data indicating the three-dimensional shape of the unit structure of the temporary scaffold) is created in advance, and the unit structure of the temporary scaffold is designated from the outside using the second shape data of the unit structure of the temporary scaffold. The temporary scaffold is assembled in a state according to the structure, and the unit structure of the assembled temporary scaffold is displayed three-dimensionally together with the structure based on the first shape data, so that an appropriate temporary scaffold according to the situation of the structure There has been proposed a temporary scaffold design support device that can be designed easily and quickly and that can improve the prediction accuracy of materials necessary for the temporary scaffold installation (see, for example, Patent Document 1).

Japanese Patent No. 5460431

However, in the design support device for the temporary scaffold disclosed in Patent Document 1, it is assumed that the first shape data indicating the three-dimensional shape of the structure is used. For this reason, the design support device of the temporary scaffold of Patent Document 1 is limited in use when constructing a structure or repairing a structure in which the first shape data is stored, and is applied to all structures. However, there is a problem that it cannot be applied.
Moreover, even if the first shape data of the structure exists, the first shape data indicating the initial state of construction cannot be used if the structure is repaired or accompanied by modification or shape change. . In this case, the current status of the remodeled part or repaired part is confirmed by, for example, drawings or photographs, and the first shape data is created by combining the two-dimensional data and the first shape data of the structure to create a temporary scaffold. In order to create new first shape data by combining two-dimensional data such as drawings and photographs and first shape data that is three-dimensional data, it is possible to use the two-dimensional data from the two-dimensional data. There is a special technique of creating three-dimensional data and incorporating it into existing three-dimensional data, and a problem that it takes time to process the data. For this reason, it is economical to create new first shape data for a structure that has undergone remodeling or shape modification and use it for the design support device of the temporary scaffold disclosed in Patent Document 1. Not realistic to think about.

If there are three or more common image feature points in the two selected images, the three-dimensional position of the viewpoint is obtained by epipolar geometry. On the other hand, if the number of image feature points common to the two selected images is 2 or less, the 3D coordinates of the feature points corresponding to the 3D position of the viewpoint and the image feature points are assumed for each selected image. The two-dimensional coordinates of the pseudo image feature points formed on the selected image are obtained, and the three-dimensional viewpoint is determined from the condition that minimizes the error between the image feature points and the pseudo image feature points on the selected image (bundle adjustment method). Seeking the position. Furthermore, since the two-dimensional coordinates of the feature points include errors, the obtained three-dimensional position of the viewpoint also includes errors. Therefore, the three-dimensional position of the viewpoint is optimized from the condition (Newton method) that minimizes the error of the three-dimensional position of the viewpoint in each selected image.

As shown in FIGS. 4 and 5, the drawing three-dimensional coordinate calculator group 34 uses the two-dimensional coordinates of the image feature points obtained by the two-dimensional coordinate calculator 32 when the drawing is set as the original data. Whether the contour in the selected image formed by connecting the image feature points in order changes constant or similar to a specific direction orthogonal to the plane in which the contour exists (whether condition 1 is satisfied), or the building 11 It is determined whether it is rotationally symmetric (whether condition 2 is satisfied) or a condition other than conditions 1 and 2. If condition 1, simple process signal 1 is determined, and if condition 2, simple process signal 2 is determined, A processing-specific signal generator 38 having a function of outputting a non-simplified processing signal in each case other than the conditions 1 and 2 is provided, and two image feature points that exist in common in each selected image (drawing) are displayed on the selected image.

Here, the feature point coordinate calculator 41 recalculates the two-dimensional coordinates of the image feature points using a coordinate system in which the center-of-gravity coordinates of the two-dimensional coordinates of the image feature points are the coordinate origins of the selected images for each selected image. To do. Further, when the number of selected images is m and the number of feature points on the building 11 is n, the position information of the image feature points on all the selected images is a matrix of “2m rows and n columns”, and all viewpoints The position information of 3 can be marked with a matrix of “3 rows and n columns”, and the position information (three-dimensional coordinates) of feature points on the building 11 can be marked with a matrix of “2 m rows and 3 columns”. Therefore, a “2m row and n column” matrix indicating the position information of the image feature points on all the selected images is converted into a “2m row and 3 column” matrix and a “3 row and n column” matrix using singular value decomposition. The three-dimensional coordinates (position) of the viewpoint and the three-dimensional coordinates (position) of the feature points on the building 11 are obtained respectively. When performing singular value decomposition, the matrix indicating the position information of the viewpoint uses an incidental condition that the X direction and the Y direction are orthogonal to each other and that the magnifications (scales) in the X direction and the Y direction are equal.

If there are less than 10 image feature points set on the selected image, the 3D position of the viewpoint and the 3D coordinates of the feature points corresponding to the image feature points are assumed for each selected image. The two-dimensional coordinates of the pseudo image feature points formed on the selected image are obtained, and the three-dimensional viewpoint is determined from the condition that minimizes the error between the image feature points and the pseudo image feature points on the selected image (bundle adjustment method). Seeking the position. In addition, since the 2D coordinates of the image feature points include errors, the 3D position of the obtained viewpoint also includes errors. Therefore, the viewpoint from the condition that minimizes the 3D position error of the viewpoint in each selected image (Newton method) is used. Optimize the 3D position of.

Can be configured by mounting in a computer. The model storage unit 23 may be a storage device (for example, a magnetic storage device such as a hard disk, a semiconductor storage device, or a magneto-optical storage device) that is connected to a computer and inputs / outputs data.

As shown in FIG. 4, the model integration unit 24 calls another 3D model stored in the model storage unit 23 and adjusts the scale (magnification) with a function of converting the created 3D model to the same scale. 3D while reading the unit 46 and the created 3D model and another scaled 3D model and adjusting the positions of the created 3D model and another 3D model in the 3D space. A model combiner having a function of combining another three-dimensional model at a predetermined position of the original model, creating a new integrated three-dimensional model, displaying it on the display 27, and storing it in the model storage means 23 47.

The created three-dimensional model includes, in addition to the three-dimensional model at the stage where the creation is completed by the three-dimensional model creator 43, another three-dimensional model stored in the model storage unit 23.

Next, creation of a three-dimensional model of the building 11 by the model creation means 22 will be described for each of the case where the original data forming the two-dimensional image is a photograph and the case where it is a drawing. When the original data forming the two-dimensional image is a photograph, the image data setting unit 25 of the image selecting unit 19 is used to set that the original data forming the two-dimensional image is a photograph, and the image storage unit 26 is set. The data is temporarily stored and displayed on the display 27. Next, from the two-dimensional images displayed on the display device 27, a plurality of two-dimensional images in which corners and wall surfaces constituting the surface of the building 11 are present in common are selected as selection images. As shown in FIG. 6, the selected selection images 48 can be displayed on the display screen 49 of the display device 27 using the selection display device 28, and the selection image can be confirmed. For each selected image 48, the auxiliary line creator 30 is used to draw a part of the contour of the selected image 48 displayed on the display screen 49, for example, a contour straight line along each corner (and parallel to the contour straight line). A supplementary line having a supplemental contour straight line) can be superimposed on the selected image 48 and displayed.

Next, as shown in FIG. 7, for each selection image 48 displayed on the display screen 49, a common angle between the selection images 48 using the image feature point setting unit 31 of the two-dimensional coordinate calculation means 20. The contour line 50 that constitutes each part and surface is designated, and a plurality of common image feature points 51 and 52 existing on the contour line 50 are set in accordance with the same preset designation order. In FIG. 8, image feature points 51 and 52 on the contour line 50, image feature points 51a and 52a on the contour line 50a, image feature points 51b and 52b on the contour line 50b, and image feature points on the contour line 50c. The state where the points 51c and 52c are set is shown. In the building 11, when all the contour lines constituting the common corners and faces are specified and all the common image feature points existing on the respective contour lines are set, the two-dimensional coordinate calculator 32 The two-dimensional coordinates in the selected image of each designated image feature point are calculated.

When the two-dimensional coordinates of all the designated image feature points 51, 52, 51a, 52a, 51b, 52b, 51c, 52c (hereinafter referred to as 51-52c) are obtained, the three-dimensional coordinate calculation means 21 uses the photographic tertiary. For each selected image 48, the original coordinate calculator group 33 obtains the three-dimensional position of the viewpoint (camera) with respect to the building 11 when the selected image 48 is taken. Subsequently, the three-dimensional coordinates of the image feature points 51 to 52c with respect to the viewpoint position are obtained and selected from the three-dimensional position of the viewpoint and the two-dimensional coordinates on the selection image 48 of the image feature points 51 to 52c based on the principle of triangulation. The coordinate transformation is performed so that the three-dimensional coordinates of the common image feature points 51 to 52c obtained for each image 48 coincide with each other, and the obtained three-dimensional coordinates are obtained on the building 11 corresponding to the image feature points 51 to 52c. Let it be the three-dimensional coordinates of the feature point.

When the three-dimensional coordinates of the feature points are specified, three or more feature points corresponding to three or more feature points existing on the closed contour line are used by using the three-dimensional model creator 43 of the model creation unit 22. Create the outer surface of the model in 3D space. Then, a model outer surface having two or more common feature points is selected, a common corner is formed from the common feature points, and the model outer surfaces are connected to each other, as shown in FIG. 9A. A three-dimensional model 55 of the object 11 is created, and the result is displayed on the display screen 49. When a model outer surface having a common feature point is selected, the first scale adjuster 44 unifies the scale (magnification) of the model outer surface to a constant value. The data of the three-dimensional model 55 is stored in the model storage unit 23.

Further, using the design display 45, the attached members (for example, provided protruding from the wall surface) displayed on each surface in the selection image 48 corresponding to the outer surface of the model constituting the three-dimensional model 55, respectively. Member) and extracted according to the position of the outer surface of the model in the three-dimensional space, and then incorporated on the outer surface of the three-dimensional model 55. As shown in FIG. The attached three-dimensional model 56 can be displayed on the display screen 49. Then, the data of the textured three-dimensional model 56 is stored in the model storage unit 23.

Here, when the three-dimensional model 55 (the same applies to the textured three-dimensional model 56) is created, another three-dimensional model stored in the model storage unit 23 is called using the model integration unit 24, The three-dimensional model 55 is converted to the same scale, for example, while adjusting the positions of the three-dimensional model 55 and another three-dimensional model in the three-dimensional space on the display screen 49 of the display device 27. A new three-dimensional model (integrated three-dimensional model) can be created by combining another three-dimensional model at 55 predetermined positions. The integrated 3D model can be displayed on the display screen 49 and can be stored in the model storage unit 23.

Next, the case where the original data forming the two-dimensional image is a drawing will be described.
First, it is set by using the image data setting unit 25 of the image selection means 19 that the original data forming the two-dimensional image is a drawing. Then, when a plurality of selected images are selected from the two-dimensional images temporarily stored in the image storage 26, the scale between the selected images is adjusted (unified) by the second scale adjuster 29. In addition, selection of selected image, overlay display of auxiliary line on selected image, specification of contour line on selected image, setting of feature point on each contour line, 2D coordinate of each feature point in selected image Since the calculation can be performed in the same manner as in the case where the original data forming the two-dimensional image is a photograph, the description is omitted.

When the two-dimensional coordinates of all the image feature points designated on the selected image are obtained, the image that exists in common in each selected image using the drawing three-dimensional coordinate calculator group 34 of the three-dimensional coordinate calculation means 21. Using the two-dimensional coordinates on the feature point selection image, the three-dimensional position of the viewpoint with respect to the building 11 (for example, when the selection image is viewed from the front, the depth direction of the selection image is the Z-axis direction, and the right direction of the selection image is X-axis direction and downward direction as Y-axis direction) are obtained, and the three-dimensional coordinates of the feature points on the surface of the building 11 corresponding to the image feature points are obtained. Here, in the processing-specific signal generator 38, the contour in the selected image formed by connecting the image feature points in order from the two-dimensional coordinates of each image feature point is in a specific direction orthogonal to the plane on which the contour exists. It is determined whether or not condition 1 that is constant or similar changes is satisfied, and if condition 1 is satisfied, simplified processing signal 1 is output. Furthermore, in the signal generator 38 classified by process, when the condition 1 is not satisfied, it is determined whether or not the condition 2 in which the building 11 is rotationally symmetric is satisfied. If the condition 2 is satisfied, the simplified process signal 2 is output. If condition 2 is not satisfied, a non-simplified processing signal is output.

When the non-simple processing signal is output from the signal generator 38 for each process, the two-dimensional coordinates of the n image feature points respectively designated on the m selected images are set, and the coordinate origin is set at the centroid position of the image feature points.
