Three-dimensional (3D) visualization or 3D monitoring of patients or infected animals is useful in actual clinical environment. We propose a 3D imaging system with a single camera and multiple mirrors. The camera is located directly above the object and the multiple mirrors are placed surrounding the object. The single captured image includes multiple viewpoint images: the object captured directly and the same objects reflected by the mirrors. After a simple calibration of the measurement, the 3D volume data are reconstructed with the visual hull based method. Texture mapping is also performed to enhance the reality. A living object was observed in usual environment using this system. The results have demonstrated effectiveness of the system.
