Abstract
A method for generating a panoramic image is disclosed. The method comprises simultaneously capturing images from multiple camera sensors aligned horizontally along an arc and having an overlapping field of view; performing a cylindrical projection to project the captured images from the multiple camera sensors to a cylindrical images; and aligning overlapping regions of the cylindrical images corresponding to the overlapping field of view based on an absolute difference of luminance, wherein the cylindrical projection is performed by adjusting a radius for the cylindrical projection, wherein the radius is adjusted based on a scale factor and wherein the scale factor is calculated based on a rigid transform and wherein the scale factor is iteratively calculated for two sensors from the multiple camera sensors.

A method for generating a panoramic image, comprising:
- capturing images simultaneously from each of multiple camera sensors aligned horizontally along an arc and having an overlapping field of view;
- performing a cylindrical projection to project each of the captured images from the multiple camera sensors to cylindrical images;
- and
- aligning overlapping regions of the cylindrical images corresponding to the overlapping field of view based on absolute difference of luminance, wherein the cylindrical projection is performed by adjusting a radius for the cylindrical projection, wherein the radius is adjusted based on a scale factor and wherein the scale factor is calculated based on a rigid transform, and wherein the scale factor is iteratively calculated for two sensors from the multiple camera sensors.
The method 6, further comprising using offset point to maintain a temporary stable seam across the cylindrical images.
