Dynamic Face Image Capture from Color Video in Conjunction with Planar Laser Scanning

〈Summary〉 We propose a system for automatic acquisition of walking persons’ faces using a color video camera in conjunction with a planar laser scanner. The system reconstructs the person’s body surface, estimates the location of the neck reference point in 3D space, and determines the location of this reference point on the image plane. Face images are then cut out with respect to this reference point. A method for estimating the motion velocity vector of the walking person, which is necessary for body surface reconstruction, is also proposed. A prototype system was built, and its evaluation showed promising results.
