Modified Phase-only Correlation Method Applied in Liquid Medicine Image Registration

JIANG Lijie;BAI Ruilin;LI Xin;Key Laboratory of Advanced Process Control for Light Industry (Ministry of Education), Information and Control Experiment Teaching Center Jiangnan University;Xinje Electronic Co.,Ltd.;  
For bottled liquid micro foreign particle visual inspection system, due to the platform and camera vibration, resulting in the bottle in image sequences with varying degrees of random offset, we propose a liquid medicine image registration method based on modified phase correlation. First, we introduce the projected image into origin phase correlation registration algorithm to divide it into two one-dimensional registration algorithms, which can greatly improve the algorithm's operation speed. Second, we introduce Hanning window function filtering to overcome the harm to the registration accuracy due to the "discontinuity" of the image edges. Third, we introduce the peak estimation technique to improve the registration accuracy to sub-pixel level. Experimental results show that the proposed method can achieve 1/100 pixel registration accuracy, and has certain immunity to luminance change and noise. The method can meet the requirement of the actual production of bottled liquid micro foreign particle visual inspection system.
