Abstract
An extended method of three—dimensional (3D) space measurement in construction plant originate in CAD Base Vision is investigated. CAD Base Vision has been used as Robot Vision extracting the real object from the camera image by matching 2D wire frame CAD model concerning to the object. In Original CAD Base Vision, the CAD model is shown by considering camera position and posture.
In extended method, the CAD model is shown by using collinearity equation considering the inner orientation parameter corrected the lenz distortion. An extended method proved a accuracy of ± 1mm.
