Three dimensional measurement apparatus, control method and program therefor, information processing apparatus, control method and program therefor

摘要

A three dimensional measurement apparatus comprising: projection means (102) for projecting a pattern including measurement and feature patterns onto an object; image capturing means (101) for capturing an image of the object onto which the pattern is projected; grouping means (106) for dividing the captured image into a plurality of regions using the measurement pattern in the pattern and a plurality of epipolar lines determined based on a positional relationship between the projection means and the image capturing means, thereby grouping predetermined regions among the plurality of divided regions; feature recognition means (106) for recognizing the feature pattern based on a difference in the feature pattern between the predetermined regions; and three-dimensional shape calculation means (107) for calculating a three-dimensional shape of the object based on the feature pattern.
