PROBLEM TO BE SOLVED: To provide a covering depth inspection device capable of directly measuring and evaluating a covering depth in managing concrete work.SOLUTION: A covering depth inspection device comprises: range data acquisition means S102 which acquires three-dimensional range data, a set of point group data, by irradiating a subject with light rays; coordination conversion means S103 which converts the acquired three-dimensional range data into the point group data based on three-dimensional orthogonal coordinates; plane extraction means S104 which extracts a point group identified as a plane from the converted point group data; first cylinder body extraction means S105 which extracts the point group identified as a first cylinder body having a first diameter from the converted point group data; second cylinder body extraction means S106 which extracts the point group identified as a second cylinder body having a second diameter from the converted point group data; and color-coded display means S107 which provides colors to the point group data depending on distances from the plane extracted by the plane extraction means. |
