The invention provides a measuring instrument, comprising a telescope, a distance measuring unit, an image pickup unit, angle detecting units for detecting a vertical and horizontal angle in the sighting direction, an automatic sighting unit, an arithmetic unit, and a storage unit. The arithmetic unit makes the telescope rotate in horizontal and vertical direction and perform scanning over a predetermined range so that a plurality of objects to be measured are included and makes the image pickup unit acquire digital images during the scanning process. The arithmetic unit detects the objects in the digital images, calculates a vertical and horizontal angle of the objects based on the angle detector and a deviation of each of the objects from sighting axis, associates the calculated angles with each of the objects, and makes the storage unit store the vertical and horizontal angles of the objects as target values for automatic sighting. |
