FIELD: control of air transport kept on ground.
SUBSTANCE: identification of axial line is performed by scanning the ramp in front of parking area by means of laser range finder and recording the reflection intensity and position for each scanned point by means of recording unit. Then, axial line in front of parking area is identified in processing unit making use of differences in reflection intensity between axial line and ramp surface surrounding the axial line, after which at least two defining marks of axial line are determined in accordance with layout of axial line.
EFFECT: accurate and prompt identification of axial line followed by check of axial line configuration.
