Motion Detection for Human Bodies Basing Adaptive Background Subtraction by Using an Omnidirectional Camera

PI Wenkai LIU Hong ZHA Hongbin (National Lab.on Machine Perception,Peking University,Beijing,100871)  
A new real-time omnidirectional vision system is proposed for tracking multiple targets in indoor environments.In this system,an omnidirectional camera is used to obtain the 360° view images of the global scene.First,it builds the background model by observing the scene without people in it.When the detecting process starts,omnidirectional images are changed into the cylindrical panoramic images,and an adaptive background subtraction method is utilized to segment the moving regions and locate the positions of human bodies.Thus,multiple human bodies can be tracked.Experimental results show that the proposed system performs well in indoor,complex environments.
