Inland waterway navigable ship superelevation detection early warning system and working method thereof

The present invention discloses an inland waterway navigable ship superelevation detection early warning system and a working method thereof. The system comprises a ship image imaging module, an on-site image remote sending module, a ship image receiving module, a VTS control center, an environment information detection module, an environment information sending/receiving module, a bridge headroom height sending/receiving module, a bridge headroom height measurement module, a calibration data module, an AIS system module, a wireless sending/receiving module and a wireless hand-held law enforcement terminal module. The inland waterway navigable ship superelevation detection early warning system and the working method thereof take a computer vision theory as basis, take the inland waterway navigable ships as the application background, and utilize the AIS devices to obtain the position information of an navigable environment, thereby being simple in system realization. The inland waterway navigable ship superelevation detection early warning system and the working method thereof realize the on-shore nondestructive test by utilizing the space information of the calibration objects and adopting an image processing algorithm, enable a ship body not to be damaged and the manpower resources to be saved, and are high in automation degree. The inland waterway navigable ship superelevation detection early warning system and the working method thereof compensate an imaging error by a coordinate system conversion calibration method, thereby being more accurate in ship height measurement.
