  • Three-dimensional measurement method using feature amounts and device using the method
    Patent number: 11257232
    Abstract: The relationship between space coordinates and a plurality of feature amounts gained from at least a pattern or a change in the pattern that has been projected from a plurality of projection units is found in advance, and the relationship between the feature amounts and the space coordinates is used in order to find the space coordinates of the surface of an object from the feature amounts that have been gained from a pattern or a change in the pattern projected from the plurality of projection units onto the surface of the object.
