In the high-precision photogrammetric, binocular vision measurement method is an efficient and feasible method. In order to explore the effect of the location relationship between cameras on measurement results, the interference factors such as camera calibration, orientation and image coordinate extraction are considered as ideal values. From the perspective of mathematics model of interchange measurement the measurement results and accuracy are analyzed through combining the main factors such as the camera field angle, merging angle and radiant angle of infrared light emitting diode (LED). It ultimately gives the stations optimization strategy by analyzing the measuring results and accuracy of the infrared LED in the measurement area which are fixed as control points at various locations between the cameras.
