SYSTEM FOR DETERMINING POSITION AND ATTITUDE OF CAMERA USING THE INNER PRODUCT OF VECTORS AND THREE-DIMENSIONAL COORDINATE TRANSFORMATION

摘要

The present invention relates to a system for determining the position and posture of a camera by using a vector dot product and a three-dimensional coordinate transformation, and more particularly, to a three-dimensional ground coordinate based on an image captured by a camera and a corresponding two-dimensional normal By determining the projection center corresponding to the camera position using the coordinate vector dot product, and determining the rotation matrix corresponding to the camera posture through the three-dimensional transformation relationship between the ground coordinates and the regular coordinates using the determined projection center, the gimbal lock It relates to a system for determining the position and posture of a camera that prevents the (gimbal lock) phenomenon from occurring and enables accurate and quick determination of exterior orientation parameters related to projection center and shooting direction.
