Abstract :
A method for determining the position of a camera using four point-targets is studied. three rotation angles and a translation vector are used to describe the position of the camera for a pinhole model. For solving the six unknown parameters, a minimum of six point-targets is required to define the matrix uniquely (rotation and translation). However, it is shown that by using the properties of the matrix this number can be reduced to four. The error properties of this method are discussed using real image data
