Magnetic marker diagnostic system and diagnostic method

A diagnostic vehicle (1) which diagnoses operation situations of magnetic markers (10) laid in or on a traveling road so as to be magnetically detectable by a vehicle includes sensor unit (11) which obtains a one-dimensional magnetic distribution by measuring a magnitude of magnetism with which any...

Beschreibung
Zusammenfassung:	A diagnostic vehicle (1) which diagnoses operation situations of magnetic markers (10) laid in or on a traveling road so as to be magnetically detectable by a vehicle includes sensor unit (11) which obtains a one-dimensional magnetic distribution by measuring a magnitude of magnetism with which any of magnetic markers (10) acts therearound, line sensor camera (13) which obtains a marker image, which is one-dimensional image information, by imaging magnetic marker (10), and diagnosing unit (15) which determines the presence or absence of a flaw in magnetic marker (10) based on a comparison between a magnetic distribution and the marker image.
