This white paper explains horizon straightening, a feature in panoramic multisensor cameras that corrects image distortion caused by camera tilt. When cameras are angled downward to capture more ground, the horizon can appear curved due to projection effects. Horizon straightening compensates for this by reprocessing the image to produce a visually straight horizon and maintain vertical alignment of objects. The paper also discusses trade-offs, such as loss of image data in the corners or the need to stretch pixels to fill gaps. Overall, the feature improves visual clarity and enhances the usability of panoramic images, especially for monitoring and analytics applications.
