Abstract
Method for determining a coordinate system including a preliminary measurement step in which a detector of a coordinate measuring apparatus is used to scan first measurement areas of the device to obtain position coordinate information and the detector is used to scan a second measurement area that is not on a straight line connecting the first measurement areas to obtain position coordinate information; a feature-point detection step of obtaining the position of a feature point in each of the measurement areas according to a result of measurement; a reference-line determination step of obtaining a first reference line according to the position of each feature point in the first measurement areas, and obtaining a second reference line perpendicular to the first reference line and passing through a feature point located in the second measurement area; an origin-setting step; and an axis setting step.
