    摘要: A rotary stage is controlled to two measurement positions along a rotational direction in which an object surface is moved when detecting a wavefront of reflected light from partial regions by a detecting unit, to move the object surface. Respective placement errors in a trajectory of the object surface at the two measurement positions are measured based on wavefronts detected by the detecting unit in states in which the rotary stage is controlled to each of the two measurement positions. For the remaining measurement positions among the measurement positions, respective placement errors with respect to the trajectory of the object surface are estimated based on the placement errors measured. Before measurement of each item of partial shape data, the rotary stage is controlled to a measurement position and stages are controlled to a position that cancels a placement error at the measurement position to align the object surface.

    摘要: The present invention provides a system and method (400) of generating a three-dimensional model of an object. The method (400) includes capturing first image and range data corresponding to a first portion of the object from at least two different positions (step 405) and generating a first three-dimensional model of the first portion of the object using the first image and range data (step 410). The method further includes capturing second image and range data corresponding to a second portion of the object from at least two different positions and generating a second three-dimensional model of the second portion of the object using the second image and range data (step 415). The first and second portions are overlapping. Finally, a third three-dimensional model is generated describing the first and second portions of the object by combining the first and second three-dimensional models into a single three-dimensional model (step 420).
