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 of a work machine with a swing body and a traveling body, comprising:
 a shape measuring system provided in the swing body; 
 a storage unit configured to store a plurality of shape information obtained by the shape measuring system with the swing body swung; and 
 a processing unit configured to generate a site shape information of a construction site including a construction object constructed by a different work machine other than the work machine, by combining the plurality of shape information. 
 
     
     
       2. The construction management system according to  claim 1 , further comprising:
 a communication unit configured to transmit the site shape information to the different work machine. 
 
     
     
       3. A construction management system of a work machine with a swing body and a traveling body, comprising:
 an imaging device provided in the swing body; 
 a storage unit configured to store a plurality of images captured by the imaging device with the swing body swung; and 
 a processing unit configured to apply image processing by a stereo method to the plurality of images so as to generate a plurality of shape information; wherein 
 the processing unit is further configured to generate a site shape information of a construction site including a construction object constructed by a different work machine other than the work machine, by combining the plurality of shape information. 
 
     
     
       4. A construction management method of a work machine with a swing body and a traveling body, comprising:
 obtaining a plurality of shape information, by the shape measuring system provided in the swing body with the swing body swung; and 
 generating a site shape information of a construction site including a construction object constructed by a different work machine other than the work machine, by combining the plurality of shape information. 
 
     
     
       5. A construction management method of a work machine with a swing body and a traveling body, comprising:
 capturing a plurality of images by the imaging device provided in the swing body with the swing body swung; 
 applying image processing by a stereo method to the plurality of images so as to generate a plurality of shape information; and 
 generating a site shape information of a construction site including a construction object constructed by a different work machine other than the work machine, by combining the plurality of shape information.
