Camera calibration without control points and automated orientation are being received attention for the operatinalization of digital photogrammety. Ideally, real-time camera calibration could be performed by using GPS and optical gyro. Such these equipments, however, are not widely diffuse due to the price aspect. Then, it is thinkable following two ways as a calibration method that is not depend on these equipments. One is a reducing control points by utilizing information such as distances which are included on the image. Another is a utilizing special equipment such as video theodolite.
This paper presents the above two calibration methods for real-time photogrammetry.
