Point group data synthesis apparatus, non-transitory computer-readable medium having recorded thereon point group data synthesis program, point group data synthesis method, and point group data synthesis system

Abstract

A point group data synthesis apparatus includes: an image acquisition unit that acquires a plurality of images including a working target; a point group acquisition unit that acquires, for each of the images, point group data on a camera coordinate system with reference to a camera that photographs the images; a detection unit that detects each position on the camera coordinate system of a visual characteristic point commonly included in the respective images; a user coordinate system setting unit that sets a user coordinate system with reference to the position on the camera coordinate system of the characteristic point detected for each of the images; a coordinate conversion unit that converts, for each of the images, the point group data on the camera coordinate system into point group data on the user coordinate system; and a point group synthesis unit that synthesizes the point group data on the user coordinate system converted for each of the images together.
