Based on the coordinate transformation eyes positioning model

To precisely determine the relative position of the two cameras is an important problem for the digital camera binocular positioning, this paper solve the digital camera system calibration problem. First, established coordinates system of two cameras, and did the coordinate transformation, and used least square method, fixed the image coordinates of the geometric center on the target in the camera image plane; Second, provided the mathematical model and the calculation method of the coordinate transformation according to the target to determine the relative position of the two fixed cameras, and analysed the mathematical model. This is a simple and reliable method to simulate for human eyes, it has a lot of applications in measurement, control ect.
