Construction management system, construction management method, and management device

Abstract

A construction management system includes: an object detecting unit mounted on a work machine and configured to detect an object in a construction site and output information on the object; a shape detecting unit configured to output shape information indicating a three-dimensional shape of the object by using the information on the object detected by the object detecting unit; an information attaching unit configured to attach, to the shape information, time information indicating a time when the object is detected; and a management device configured to generate current state information on the construction site on the basis of the shape information to which a latest piece of the time information is attached.

The invention claimed is: 
     
       1. A construction management system comprising:
 an object detecting unit mounted on a work machine and configured to detect an object in a construction site and output information on the object; 
 a shape detecting unit configured to output shape information indicating a three-dimensional shape of the object by using the information on the object detected by the object detecting unit; 
 a construction information generating unit configured to generate target construction information by using the shape information; and 
 a communication unit configured to transmit the target construction information. 
 
     
     
       2. The construction management system according to  claim 1 , wherein
 the communication unit is further configured to transmit the target construction information to a work machine other than the work machine. 
 
     
     
       3. The construction management system according to  claim 1 , wherein the communication unit is further configured to transmit the the target construction information to a management device configured to communicate with the work machine. 
     
     
       4. The construction management system according to  claim 1 , wherein the object includes at least a construction planned portion different from a construction planned portion by the work machine, and a constructed portion different from a constructed portion by the work machine. 
     
     
       5. The construction management system according to  claim 1 , wherein a removed soil amount or a banked soil amount is obtained on the basis of pieces of the shape information obtained at different times. 
     
     
       6. The construction management system according to  claim 1 , wherein the shape detecting unit includes at least two imaging devices. 
     
     
       7. The construction management system according to  claim 1 , wherein
 the object includes at least one of a construction planned portion and a constructed portion by a unit other than the work machine. 
 
     
     
       8. The construction management system according to  claim 7 , wherein a removed soil amount or a banked soil amount by a different work machine is obtained on the basis of pieces of the shape information obtained at different times. 
     
     
       9. The construction management system according to  claim 7 , wherein shape information on an entire construction site is generated by using at least one of a construction result by the work machine, a construction result by a different work machine, and a construction result by neither the work machine nor the different work machine.
