This paper proposed an efficient omnidirectional surveillance system for digital home security. In this surveillance system, the omnidirectional scenes in a room, kitchen, car porch, dining hall, corridor, garage or backyard within a digital home are first captured using a web camera attached to a hyperbolic optical mirror. The captured scenes are then fed into a laptop computer for image processing and alarm purposes. Log-polar mapping is proposed to map the captured omnidirectional image into panoramic image, hence providing the observer or image processing tools a complete wide angle of view. A trespasser detection algorithm is also designed for trespasser detection purpose. The observed significances of this new proposed surveillance system include: it can cover a wide angle of view (360deg omnidirectional), small in size, low cost, lightweight, output images are with higher data compression, and accurate trespasser detection.
