Image analysis system, method and apparatus for track detection

The utility model relates to an image analysis system and device suitable for track detects, the system includes: the image acquisition unit is arranged on the rail transit vehicle and is used for acquiring the image of the rail when the rail transit vehicle passes through the rail; and a processing unit that processes the acquired image to determine a state of the track, the processing unit including: the device comprises an image extraction module, an image positioning module, a geometric judgment module and a track analysis module. According to the utility model discloses an image analysis system can reduce the track and detect the cost, improves track detection efficiency, has eliminated because the huge influence that motion such as train turn, ups and downs and nod produced image method track detection to can utilize the unit image to carry out three-dimensional space coordinate location to detecting the track.
