One New Calibration on underwater polarization image
The calibration of polarization imaging system is the premise to obtain target polarization information accurately,in this paper,we propose a method of calibration based on the radian of distorted curves in the checkboard to solve the problem of losing polarization information in the underwater distorted polarization images.Firstly,we use the radian of distorted curves in the checkboard to calculate the coordinates of distortion center,and calibrate the region near the distortion center.Then we use the calibrated region to reconstruct the whole image.Finally,we combine the distorted image,the reconstructed image and the distortion model to obtain the calibration parameters.With these parameters we can get the calibrated polarization images.The experiments show that our method can calibrate the polarization image accurately,reduce the coupled error and calculate parameters independently.
