Information sensing and sharing system for supporting rescue operations from burning buildings
First Claim
1. A system for automatic mapping of a walled structure, the system comprising at least one mobile unit including:
- (a) a position tracking system for tracking a current position of said mobile unit;
(b) a wall detection system including a sensor arrangement for measuring range data from said mobile unit to at least four points; and
(c) a mapping processor associated with both said position tracking system and said wall detection system, said mapping processor being configured to process said range data and, if said at least four points lie on a common plane according to a defined criterion, mapping a wall in corresponding spatial relation to said current position.

Abstract
A system for automatic mapping of a walled structure includes at least one mobile unit, preferably worn by a user. The mobile unit has a position tracking system for tracking a current position of the mobile unit, a wall detection system including a sensor arrangement for measuring range data from the mobile unit to at least four points, and a mapping processor associated with both the position tracking system and the wall detection system. The mapping processor processes the range data and, if the at least four points lie on a common plane according to a defined criterion, maps a wall in corresponding spatial relation to the current position. The mobile unit preferably also includes a wireless communication link for transmitting and receiving data indicative of the mapped walls to other mobile units and to a remote command control unit.
