Paper Abstract

We present a method for building panoramic video for Video GIS. Video GIS(geographic information system) is a new field of mosaics application, which utilized for the automobile navigation system and the panoramic video which composed of several images taken by adjacent cameras provides sufficient information to a first trip driver. The perspective transformation, which estimated from the appropriate corresponding pairs between adjacent images, can construct the panoramic video without unwilling distortions. We use corner points for the corresponding feature, and local peak detection of corner strength estimated from morphological structures are utilized for fast and robust corner detection. The criterion method of corner strength we proposed, guarantees the robust detection of corner in any situations. For the perspective transformation, 8-parameters are estimated from perspective equations, and four pairs of matched points in the adjacent images are selected via pattern matching of corner points to construct the equations. In general, when we stitch two adjacent images together by using 8-parameter transform, some unwanted discontinuities of intensity or color will exist between their common areas and bilinear blending technique is used to construct a seamless panorama. Experiments show that our method yields good results in various conditions.
