Other AbstractPSD vision sensor has a great advantage in terms of visual pose measurement due to less affect by light and the simple data processing. However, due to the non-linearity of the PSD sensor itself, the distortion of the PSD sensor is complex and the calibration of the PSD sensor becomes the key to its application. Aiming at the PSD vision measurement system composed of PSD camera and infrared LED light source, a PSD camera calibration method is proposed. The method uses polynomial model to characterize the PSD camera distortion, combined with the traditional pinhole imaging model to form the PSD camera imaging model. Non-linear optimization is used to get calibration camera model parameters. A dedicated infrared LED calibration board is designed to achieve PSD vision measurement system calibration. Experimental results show that this method has high calibration accuracy for PSD camera. With this calibration result, the position and orientation measurement accuracy is high and the speed is fast, which can meet the demand of high precision optical measurement.
