Abstract:
A three-dimensions measuring method, comprising the following steps:a first step for specifying at least three points on a plane &agr; including measuring points of an object to be measured and measuring distances to and angles relative to at least three points corresponding to the specified points as viewed from a point of origin; a second step for determining an equation for specifying the plane &agr;, using data about the distances and angles obtained in said first step; a third step for collimating the measuring points from the point of origin to thereby measure angles and determining an equation indicative of a straight line connecting between the point of origin and said each measuring point; and a fourth step for computing a measuring point corresponding to a point where the equation for specifying the plane &agr;, which is obtained in said second step and the equation indicative of the straight line connecting between the point of origin and said each measuring point, said equation being obtained in said third step, intersect.
