WIPO Patent Application WO/2021/191976
Kind Code:
A1
Abstract:
This weight estimation device according to one embodiment is characterized by comprising: an acquisition means which acquires three-dimensional point group data representing a depth value at each point of a weight estimation target; a creation means which creates a projection image in which the point group data acquired by the acquisition means is projected onto a two-dimensional plane; a calculation means which calculates a prescribed index value by using at least one among the point group data and the projection image; and an estimation means which uses the index value calculated by the calculation means to estimate the weight of the estimation target by using a pre-created estimation model.
