 note = {A camera calibration technique plays an important role in the field of robot vision. There are a lot of techniques to this field for several decades. In this paper  we present a method for determining the position of a camera using a few target-points. We use 3 rotation angles and translation vector to describe the position of the camera for a pinhole model. In general  for solving the 6 unknown parameters  a minimum of six target-points in a world coordinate system is required to uniquely define the matrix. However  we show that by using the properties of the matrix we can reduce this number to four. Some experimental results of this method using synthetic data and real image data are also shown., A camera calibration technique plays an important role in the field of robot vision.
