| 摘要 |
The present invention combines real-time infrared (IR) images (3 6) of a fire (11) taken at the time of the fire, with digital images of the area where the fire rages, taken at some previous time. The two types of images are registered and the IR images are superimposed upon the digital images, thereby providing the fire-fighting forces with information regarding the types of objects (e.g. houses (20), trees (22), roads (24), etc.) which lie in the path of the fire. A system is provided which includes a viewing unit and a ground station (44). The viewing unit is mounted on an airborne vehicle (42), an unmanned airborne vehicle (40), or a fire watch tower, and includes a temperature sensitive sensor, such as an IR-sensor, for measuring the hot areas of the scene.
