Logical Stitching: A Panoramic Image Stitching Method Based on Color Calibration Box

In this paper, we present a novel method to stitch two fisheye images into a panoramic image by using a color calibration box. The color calibration box is a new calibration tool with five planes for double fisheyes camera to calibrate. With the color calibration box, we obtain parameters used in ou...

Description
Summary:In this paper, we present a novel method to stitch two fisheye images into a panoramic image by using a color calibration box. The color calibration box is a new calibration tool with five planes for double fisheyes camera to calibrate. With the color calibration box, we obtain parameters used in our method to map the fisheye images back to the same logical sphere and stitch them according to the imaging model of the two fisheye cameras aligned back-to-back. Experimental results show that our method can not only produce 360-degree panoramic scenes but also eliminate the brightness difference from the two fisheye cameras. Moreover, our approach achieves comparable stitching performance with Gear360 camera in stitching details, and outperforms it in handling stitching colors.
