Abstract:
1. A pipe installation support apparatus comprising: an acquiring device for acquiring, as point group data that is a group of point information, a three-dimensional measurement result regarding shapes of an end face of each of two pipes already installed in a facility and a section at any position of a linear portion adjacent to the end face, and shapes of each of end faces at both ends of a pipe to be attached for connecting the two pipes already installed and a section at any position of a linear portion adjacent to the end face; a three-dimensional data generating device for generating three-dimensional data of the pipes already installed and the pipe to be attached, based on the point group data acquired by the acquiring device; an image generating device for generating images of the pipes already installed and the pipe to be attached, based on the three-dimensional data of the pipes already installed and the pipe to be attached as generated by the three-dimensional data generating device; a display control device for displaying the images of the pipes already installed and the pipe to be attached generated by the image generating device on a display device; an input device for inputting a movement instruction to move at least one of the image of the pipes already installed and the image of the pipe to be attached as displayed on the display device by the display control device, to any position, or rotate at least one of the image of the pipes already installed and the image of the pipe to be attached by any angle; a moving device for translating or rotating at least one of the three-dimensional data of the pipes already installed and the three-dimensional data of the pipe to be attached, based on the movement instruction when the movement instruction is input from the input device, wherein when the moving device translates or rotates the three-dimensional data, the display control device moves the images of the pipes already installed and the pipe to be attached displayed on the display device based on translation or rotation; an interference investigating device for determining whether the three-dimensional data of each of the pipes already installed and the three-dimensional data of the pipe to be attached after being translated or rotated by the moving device, interfere with each other; a machining amount calculating device for calculating, when the interference investigating device determines that the pipe to be attached and each of the pipes already installed interfere with each other, a length of an interference portion between the pipe to be attached and each of the pipes already installed, as a distance between evaluation points correlated with each other, the evaluation points which are obtained by searching for evaluation points at a closest distance from evaluation points placed on an end face of the pipes already installed at equal internals and from evaluation points placed on an end face of the pipe to be attached at equal intervals,and for calculating the length of the interference portion as a machining amount of the pipe to be attached; and an output device for outputting the machining amount calculated by the machining amount calculating device to at least one of the display device and an external device.
