Panoramic imaging company Altia Systems has partnered with Intel to launch PanaCast Whiteboard, a computer vision software that detects content on an existing whiteboard and displays it as an individual screen within a video conference.

Panacast Whiteboard is designed to be a computer vision capability for the PanaCast 2 camera system from Altia Systems. Panacast 2 is a panoramic camera system with three separate imagers and an adjustable field of view through a USB video class (UVC) PTZ (pan, tilt, zoom) command set. The camera has USB 2.0 and USB 3.0 interfaces and features a 180° wide by 54° tall field of view, enabling it to see an entire meeting space without the use of electromechanical PTZ cameras.

To capture images from all three imagers and to provide panoramic video, the PanaCast features a patent-pending Dynamic Stitching technology, which does an analysis of the overlapping image. Once the geometric correction algorithm has finished correcting sharp angles, the Dynamic Stitching algorithm creates an energy cost function of the entire overlap region and comes up with stitching paths of least energy, which typically lie in the background, according to Altia Systems.
