Constructing Panoramic High Dynamic Range Image Based on Different Amounts of Exposures

Abstract

Abstract: A method of constructing panoramic high dynamic range image was proposed. The classical method about different amounts of exposures was adopted by choosing sampling point carefully to generate better response curves for each child camera of the panoramic camera. Weighted method was applied to obtain panoramic response curve based on six response curves of each child camera. According to characteristics of spatial frequency, a template of panoramic image was selected, so as to complete the synthesis of high dynamic panoramic image. Experiments show that the response curve of panoramic camera can better reflect the characteristics, so the generated high dynamic panoramic image shows details of both high light and dark regions. The results can be used to get luminance information of real scenes, so as a result of it, virtual object illuminating can be implemented in order to obtain the illumination consistency.

Key words: high dynamic image, panoramic image, response curve, exposure, fusion reality
