Description
Summary:An image mosaic method based on multi-constraint was proposed to achieve the sequence images mosaic based on vehicle-borne quickly. Firstly, Harris corners of the sequence images were extracted after the distortions were eliminated. Secondly, a matching algorithm based on multi-constraint was applied to get 3 correct pairs of matching points between the adjacent frames. Furthermore, the parameters of the rigid transform matrix were calculated with least squares method. Then, a global registration strategy was adopted to avoid error accumulation. Finally, image fusion method with the weighted mean was used to achieve the sequence images mosaic. Experimental results show the method achieves the sequence images mosaic quickly and accurately.
