When being used to obtain described disaster relief subsystem and being in original state, the 3rd acquiring unit of the first projection coordinate value of described suspicious object on the CCD of described variable field of view video camera image planes is connected with described second processing unit;

After being used to obtain described disaster relief subsystem adjustment state, the second projection coordinate value of described suspicious object on the CCD of described variable field of view video camera image planes, and the 4th acquiring unit of the described disaster relief subsystem rotational angle when adjusting state, be connected with described second processing unit, behind the described disaster relief subsystem adjustment state, described suspicious object is in the center of image scene of the described zone of protection of described variable field of view video camera picked-up, the focal length when described variable field of view focus of camera is in original state greater than described disaster relief subsystem;

Be used for according to described first projection coordinate's value, described second projection coordinate's value and the described disaster relief subsystem rotational angle when adjusting state, calculate second computing unit of the volume coordinate of described suspicious object, be connected with described the 4th acquiring unit with described the 3rd acquiring unit.

14. disaster relief system according to claim 1 is characterized in that, also comprises:

Be used for providing the disaster relief medium of disaster relief medium to supply with subsystem, be connected with described disaster relief subsystem to described disaster relief subsystem.
