Peeling/flaking specification device, method, and program

Abstract

Provided are a peeling/flaking specification device, method, and program capable of specifying a peeling/flaking portion on a surface of concrete or the like of a building. A processor of the peeling/flaking specification device acquires three-dimensional measurement data of a surface of a building measured by a three-dimensional measurement device such as a LiDAR (step S10). The processor compares the three-dimensional measurement data with reference surface data of the building to detect a depressed portion on the surface of the building (step S20). The processor determines whether or not the detected depressed portion is depressed beyond a first threshold value and whether or not the depressed portion is fissuring (steps S30, S40). In a case where the determination is made that the depressed portion is depressed beyond the first threshold value and is not the fissuring, the depressed portion is specified as the peeling/flaking portion (step S50).

Dependencies are inferred from the claim text.
