METHOD, SYSTEM AND APPARATUS FOR DETECTION OF EARTH SURFACE STATE

PROBLEM TO BE SOLVED: To provide an earth-surface-state detection method in which, e.g. in a runway, an earth surface state causing a trouble in a safe operation of an aircraft such as an F0 state, a pavement crack state, an upheaval state, a wet state, a freezing state or the like can be detected i...

Summary:PROBLEM TO BE SOLVED: To provide an earth-surface-state detection method in which, e.g. in a runway, an earth surface state causing a trouble in a safe operation of an aircraft such as an F0 state, a pavement crack state, an upheaval state, a wet state, a freezing state or the like can be detected irrespective of a takeoff, and a landing of the aircraft and irrespective of weather and which can reduce an operation by an inspector; and to provide an earth-surface-state detection system and an earth-surface-state detection apparatus. SOLUTION: A plurality of laser radars 2 which calculate a distance up to an object existing in an earth-surface region, and a plurality of ultraviolet image sensors 3 which detect short-wavelength light contained in a range at a wavelength of 190 to 500 nm so as to image the earth-surface region, are installed on both sides of the runway 1. The earth-surface-state detection apparatus 40 which can communicate between the laser radars 2 and the sensors 3 acquires information indicating the distance and information indicating an image so as to detect the earth surface state.
