WIPO Patent Application WO/2022/059157

A1

To set a scale for three dimensional data composed from point cloud data: a plurality of reference objects (22) of sizes and shapes known in advance are disposed around an object (20) under measurement; image data or position data obtained by imaging the object (20) under measurement together with the plurality of reference objects (22) from various angles is input to a computer (30); the known sizes and shapes of the reference objects (22) are input to the computer (30); and the computer (30) acquires point cloud data for the object (20) under measurement and each reference object (22) from a plurality of pieces of the image data or a plurality of pieces of the position data, determines, as reference objects, objects in the point cloud data having sizes and shapes within prescribed error ranges with respect to the sizes and shapes input for the reference objects (22), and sets the overall scale of the point cloud data by extending/contracting and/or twisting the point cloud data such that each of the determined reference objects has the input size and shape.
