In this study, we realized a determination method for the area of fire origin by using an angle between object and its shadow which is projected on the floor from the CCTV visual display not directly taken fire origin. This method use the transformation process that the distortion calibration and calibrated display of CCTV are converted to top view display. The area of fire origin is determined by the distance between and object and a fire origin. To predict a fire origin through transformation of CCTV visual display expand the application of CCTV and the scope of evidence. Because of no additional conditions, this method can be recognized as being more valuable than traditional ways.
