    Abstract: Abnormality detection apparatus acquires reference point cloud data and inspection point cloud data for each of a plurality of parts in a space including a target object. The reference point cloud data includes point data representing a three-dimensional position and luminance at reference time for each of a plurality of parts. The inspection point cloud data includes point data representing a three-dimensional position and luminance at time of inspection for each of the plurality of parts. The abnormality detection apparatus generates difference point cloud data representing a difference in luminance between the reference time and the time of inspection for each of the parts, detects an excluded part to be excluded from a detection target of an abnormal part, and detects an abnormal part of the target object from the parts other than the excluded parts by using the difference point cloud data.

    Abstract: There is provided a surface abnormality detection device, and a system, capable of detecting an abnormal portion having a displacement below the distance measurement accuracy when detecting the abnormal portion on the surface of a structure. A surface abnormality detection device includes a classification means for classifying an object under measurement into one or more clusters having the same structure, based on position information at a plurality of points on a surface of the object under measurement; a determination means for determining a reflection brightness normal value of the cluster based on a distribution of reflection brightness values at a plurality of points on a surface of the cluster; and an identification means for identifying an abnormal portion on the surface of the cluster based on a difference between the reflection brightness normal value and the reflection brightness value at each of the plurality of points.

    Abstract: Provided are a processing device, a system, a method, and a non-transitory computer readable medium capable of reducing false detection when detecting a foreign body. An acquisition means (111) that acquires first distance data (d1) between a predetermined point (pp) on a surface of an object (51) and a first measurement position (p1) outside the object (51) and acquires second distance data (d2) between the predetermined point (pp) and a second measurement position (p2) outside the object (51), a difference calculation means (112) that calculates difference data (dd) between the first distance data (d1) and the second distance data (d2), and a difference deletion means (113) that deletes a part of the first distance data (d1) or the second distance data (d2) on the basis of the difference data (dd) are included. The acquisition means (111) acquires the second distance data (d2) by assuming, as the predetermined point (pp), an intersection point (x1) between a line (L1) connecting the predetermined point (pp) and the second measurement position (p2) and the surface of the object (51).
