Abstract

A shape measuring system includes an object detection unit attached to a work machine and configured to detect an object and output information of the object, a shape detection unit configured to output shape information representing a three-dimensional shape of the object by using the information of the object detected by the object detection unit, and an information providing unit configured to attach time information for specifying the shape information to the shape information and output the shape information.

First claim

1 . A construction management system comprising:
an object detection unit attached to a work machine and configured to detect an object and output information of the object; a shape detection unit configured to output shape information representing a three-dimensional shape of the object by using the information of the object detected by the object detection unit; an information providing unit configured to provide time information for specifying the shape information to the shape information; and a management device configured to acquire the shape information and generate, by using the shape information, current state information indicating a current situation of the object, wherein the management device is configured to generate the current state information by using the shape information to which the latest time information has been provided.

2 . The construction management system according to claim 1 , wherein
the time information includes information of at least one time existing from a time when the object has been detected by the object detection unit to a time when an external device of the work machine has acquired the output shape information.

3 . The construction management system according to claim 1 , wherein
the information providing unit is configured to further output information indicating a position of the object detection unit and information for identifying the object detection unit.

4 . The construction management system according to claim 1 , wherein the shape detection unit and the information providing unit are provided in the work machine.

5 . The construction management system according to claim 1 , wherein
the work machine includes a posture detection unit configured to output a posture of the work machine, and the shape detection unit and the object detection unit are attached to the work machine, and the shape information is obtained by using the posture of the work machine of when the object detection unit has detected the object, the posture having been detected by the posture detection unit.

6 . The construction management system according to claim 1 , wherein
the work machine includes a position detection unit configured to detect an azimuth of the work machine, and the shape detection unit is configured to obtain the shape information by further using the azimuth of the work machine of when the shape detection unit has detected the object, the azimuth having been detected by the position detection unit.

7 . The construction management system according to claim 1 , wherein information of a landform of a current situation of an entire construction site of the work machine is output by using the shape information to which the time information is attached.

8 . The construction management system according to claim 1 , further comprising: a display device configured to chronologically display information of a landform of an entire construction site of the work machine by using a plurality of pieces of the shape information to which the time information is attached.

9 - 13 . (canceled)

14 . The construction management system according to claim 1 , wherein the management device is configured to generate the current state information by using a plurality of pieces of the shape information.

15 . The construction management system according to claim 1 , wherein
a shape measuring system comprises the object detection unit, the shape detection unit, and the information providing unit, and the management device is configured to acquire the shape information from a plurality of the shape measuring systems to generate the current state information.

16 . A construction management system comprising:
an object detection unit attached to a work machine and configured to detect an object and output information of the object; a shape detection unit configured to output shape information representing a three-dimensional shape of the object by using the information of the object detected by the object detection unit; an information providing unit configured to provide time information for specifying the shape information to the shape information; and a management device configured to acquire the shape information, wherein the management device is configured to combine pieces of the shape information having the same time information or the time information regarded as the same.

17 . A construction management system comprising:
an object detection unit attached to a work machine and configured to detect an object and output information of the object; a shape detection unit configured to output shape information representing a three-dimensional shape of the object by using the information of the object detected by the object detection unit; an information providing unit configured to provide time information for specifying the shape information to the shape information; a management device configured to acquire the shape information and generate, by using the shape information, current state information indicating a current situation of the object; and a display device configured to display the current state information, wherein the display device is configured to chronologically arrange and display the current state information, or display the current state information by frame advance in every time.
