Abstract
In this paper, we mainly discuss about three topics. We first describe the sensor system for indicating In-Rubble shape information which was developed by the authors. Secondly we discuss the evaluation of our sensor by a professional fire fighter. We finish giving a brief explanation about the new sensor system for indicating In-Rubble 3D images. The merit of this sensor system is that it can not only get images, but get the shape information of In-Rubble. Fire fighters(users) can know the space of In-Rubble, if they use this sensor system. It is crucial to know the space of In-Rubble to find possible passage for rescuing victims.
