Abstract
(A) The surface shape of an object (1) is measured by varying the position and/or direction of measurement, and a plurality of sets of partially measured data (2) including the common parts (2a) are acquired, (B) for all the partially measured data (2), the overlapped ranges (3a) of the adjacent common parts (2a) are determined within the measurement error ranges (3), (C) when there are no superposition ranges (3a), it is decided that a combination is not possible, and (D) when there are overlapped ranges (3a), the common parts of each set of partially measured data are combined within the ranges. Thus, combined data can be created at a high accuracy from a plurality of sets of partially measured data based on a small number of repeated calculations.
Claims5
A method of combining partially measured three-dimensional data, comprising the steps of:
- (A) measuring the three-dimensional surface shape of an object with a noncontact measuring device by varying the position or direction of measurement, or by varying the position and direction of measurement, followed by acquiring a plurality of sets of partially measured three-dimensional data which include common parts;
- (B) for all sets of partially measured data, determining overlapped ranges for adjacent common parts in measurement error ranges;
- (C) when there are no overlapped ranges, making a decision that no combination can be made;
- and
- (D) when there are overlapped ranges, combining the common parts of each set of partially measured three-dimensional data.
