Fast panoramic image generation method using morphological corner detection

Abstract

We present a method of building a panoramic image from adjacent images. The panoramic image is constructed using several images taken by adjacent cameras or parsed from a video, and used for photogrammetry or many computer graphic applications. The perspective transformation, which is estimated from the appropriate corresponding pairs of images, can be used to construct the panoramic image without unwarranted distortion. We used the corner points for the corresponding features, and morphological structures were utilized for fast and robust corner detection. We used the criterion of the corner strength, which guarantees the robust detection of the corner in most situations. For the transformation, 8 parameters were estimated from perspective equations, and bilinear color blending was used to construct a seamless panoramic video. The experiments showed that the proposed method yields fast results with good quality under various conditions. © Springer-Verlag Berlin Heidelberg 2005.
