Abstract :
In this paper, a new 3D-PDD (Position Determination Device) is developed based on PSD (Position Sensitive Detector) sensor. Vision sensor uses PSD camera modules, and relative position and distance from a target point to PSD sensors are calculated via stereo vision. A LED driver module at target point consists of IR LEDs and LED driver chip, and emits Infrared Ray proportional to the relative distance. DSP module processes analog signal from PSD sensors and band pass filter. Camera calibration is implemented by way of high order polynomial in order to compensate lens distortion. Effectiveness of the proposed method will be demonstrated via integrated ground test.
