Automatic surveying equipment and three-dimensions measuring method

摘要

A lightwave range finder capable of performing non-prism measurements has an angle measuring unit and a distance measuring unit. The angle measuring unit and the distance measuring unit can respectively measure distances to and angles relative to at least three specified points on a plane alpha including measuring points of the object to be measured. A computing unit can determine an equation for specifying the plane alpha from the distances to and angles relative to the specified points, determine an equation indicative of a straight line for connecting the measuring points from the angles relative to the measuring points, and compute a measuring point corresponding to a point where the plane alpha and the straight line intersect. <IMAGE>
