N2 - A method for determining the position of a camera using 4 point-targets is studied. We use 3 rotation angles and translation vector to describe the position of the camera for a pinhole model. For solving the 6 unknown parameters, a minimum of six point-targets is required to uniquely define the matrix (rotation and translation). However, we show that by using the properties of the matrix we can reduce this number to four. In the experiment we discuss the error properties of this method using real image data.
