Information processing apparatus, method therefor, and measurement apparatus

摘要

A spread degree of a geometric feature in a surface of an object to be measured is estimated. The geometric feature is included in a geometric pattern, and will be observed in an image obtained by capturing the object on which the geometric pattern is projected. A parameter is set based on the estimated spread degree. Based on the parameter, a point on the geometric pattern is set in a captured image obtained by capturing the object to be measured on which the geometric pattern is projected. A three-dimensional position on the surface of the object corresponding to the set point is calculated.

1. An information processing apparatus comprising:
an estimation unit configured to estimate a spread degree of a geometric feature projected onto a surface of an object to be measured, wherein the geometric feature is included in a geometric pattern projected onto the surface of the object to be measured, and is observed in an image obtained by an image capture unit that captures an image of the object on which the geometric pattern is projected; a parameter setting unit configured to set a parameter based on the estimated spread degree; a point setting unit configured to determine, based on the parameter, a point location of the geometric pattern in a captured image obtained by capturing the image of the object to be measured on which the geometric pattern is projected; and a calculation unit configured to calculate a three-dimensional position on the surface of the object corresponding to the determined point, wherein at least one of the estimation unit, the parameter setting unit, the point setting unit, or the calculation unit is implemented using a processor.
