Abstract
A three-dimensional point cloud generation method for generating a three-dimensional point cloud including one or more three-dimensional points includes: obtaining (i) a two-dimensional image obtained by imaging a three-dimensional object using a camera and (ii) a first three-dimensional point cloud obtained by sensing the three-dimensional object using a distance sensor; detecting, from the two-dimensional image, one or more attribute values of the two-dimensional image that are associated with a position in the two-dimensional image; and generating a second three-dimensional point cloud including one or more second three-dimensional points each having an attribute value, by performing, for each of the one or more attribute values detected, (i) identifying, from a plurality of three-dimensional points forming the first three-dimensional point cloud, one or more first three-dimensional points to which the position of the attribute value corresponds, and (ii) appending the attribute value to the one or more first three-dimensional points identified.
