Construction assistance device and construction assistance method

Abstract

There is provided a device, etc. that generates construction assistance data that can be used for generating an image that allows a user to easily understand a position and posture of an underground buried object, and for controlling operation of a construction machine to avoid contact with the buried object. In at least part of a plurality of underground search areas S i1 , S i2 , . . . , S im , S im+1 , underground search points P 1 , . . . . P i−1 , P i , P i+1 , . . . . P n−1 , P n of the underground buried objects each have a depth position from the ground surface, measured by an underground search machine 60 , and the depth positions are consolidated into a representative depth position. Then, construction assistance image data is generated that represents a three-dimensional image including closed surfaces m 1 , m 2 as objects each representing the representative depth position arranged at each of the plurality of underground search areas S i1 , S i2 , . . . , S im , S im+1 .

1 . A construction assistance device, comprising an underground search machine, wherein
 the underground search machine measures a depth position from a ground surface in each of a plurality of underground search areas, and   construction assistance data is generated that includes a plurality of objects each representing the depth position from the ground surface, the objects each being arranged in each of the plurality of underground search areas.   
     
     
         2 . The construction assistance device according to  claim 1 , wherein construction assistance data is generated such that each of the depth positions represents a representative depth position of an underground search point group consisting of one or more underground search points of a measured underground buried object. 
     
     
         3 . The construction assistance device according to  claim 2 , wherein construction assistance image data is generated as the construction assistance data, the construction assistance image data representing an image including the plurality of objects. 
     
     
         4 . The construction assistance device according to  claim 3 , wherein the construction assistance image data is generated that represents an image including a plurality of closed surfaces as the plurality of objects, the plurality of closed surfaces each being arranged at the representative depth position in each of the plurality of underground search areas. 
     
     
         5 . The construction assistance device according to  claim 4 , wherein the construction assistance image data is generated that represents an image including a single closed surface as part of the plurality of objects, the single closed surface corresponding to a result of synthesizing a plurality of the closed surfaces in each of overlapping underground search areas among the plurality of underground search areas. 
     
     
         6 . The construction assistance device according to  claim 4 , wherein the construction assistance image data is generated that represents an image including the plurality of closed surfaces having the same shape. 
     
     
         7 . The construction assistance device according to  claim 3 , wherein the plurality of objects are classified into a plurality of object groups depending on a relative arrangement aspect of each of the plurality of objects, and the construction assistance image data is generated that represents an image in which each of the plurality of objects is identifiable by a design corresponding to one object group to which the object belongs. 
     
     
         8 . The construction assistance device according to  claim 3 , wherein the construction assistance image data is generated that represents an image including a plurality of three-dimensional objects as the plurality of objects, the plurality of three-dimensional objects each extending from a ground surface to the representative depth position in each of the plurality of underground search areas. 
     
     
         9 . The construction assistance device according to  claim 8 , wherein the construction assistance image data is generated that represents an image including the plurality of three-dimensional objects having a same shape or a same shape resulting from projecting the three-dimensional object onto a horizontal plane. 
     
     
         10 . The construction assistance device according to  claim 1 , wherein the plurality of underground search areas are spaced apart from each other. 
     
     
         11 . A construction assistance method comprising:
 a step of determining a representative depth position of an underground search point group in each of a plurality of underground search areas, the underground search point group composed of one or more underground search points of an underground buried object having one or more depth positions from a ground surface measured by an underground search machine; and   a step of generating construction assistance data including a plurality of objects each arranged in each of the plurality of underground search areas so as to represent the representative depth position.
