Abstract: A display device and the like capable of displaying an entire measurement target and desired details are provided. A display device according to the present disclosure includes: a global display unit that displays a point cloud image generated using three-dimensional data including three-dimensional coordinate values of a measurement target; a position designation unit that designates a one-dimensional position in the three-dimensional data; and a local display unit that generates and displays a detailed image of the three-dimensional data based on the one-dimensional position designated by the position designation unit.

Abstract: A detection device (10) according to the present disclosure includes an acquisition unit (11) that acquires point cloud data indicating a distance from a measurement device to an object and luminance information obtained from reflected light of a beam emitted when the point cloud data is measured, an edge detection unit (12) that performs edge detection based on the luminance information, and a crack determination unit (13) that determines whether an area indicates a crack by using a shape of the area in which, of a plurality of points indicated by the point cloud data, points having luminance within a predetermined range of difference from luminance of a point detected as an edge are distributed.

Abstract: An object is to provide a measurement apparatus adapted to correctly integrate three-dimensional data acquired at a plurality of points. A measurement apparatus (10) according to the present disclosure includes a position specifying unit (11) configured to specify, using an apparatus reference coordinate system having a position of the measurement apparatus set as a reference, a position of each of a plurality of other measurement apparatuses; a candidate specifying unit (12) configured to extract at least three measurement apparatuses out of the measurement apparatus and the plurality of the other measurement apparatuses and to specify, based on the positions of the extracted measurement apparatuses, a candidate region that serves as a candidate of a common region referred to in performing alignment of data captured by the measurement apparatus and the plurality of the other measurement apparatuses; and a common region determining unit (13) configured to determine the common region based on the distribution of the plurality of the candidate regions obtained by changing combinations of the measurement apparatuses to be extracted.
