摘要：
This work concerns automatic geometric calibration in 3D parallel geometry. The aim is to develop analytical formulas to identify the view direction and the in-plane angle only from projections of the object. We consider that two view directions are known and treat all others once at a time, repeating the same three-projection procedure. We identify the unknown view direction of the third projection image and the in-plane angles of the three projections.
