A hull inspection system useable for inspecting a hull of a maritime vessel passing a water volume at a first velocity, the system comprising: pulse emitting means, for being placed in the water volume and for emitting energy pulses into said water volume; sensing means, for being placed in the water volume, and being connected to the pulse emitting means, for sensing and measuring travelling time of energy pulses reflected by the passing vessel; a sensor data processing unit; connected to the sensing means, for processing data from the sensor means; a vessel data furnishing unit, connected to the sensor data processing unit, for providing vessel velocity data to the sensor data processing unit; wherein a three-dimensional representation of the hull of the maritime vessel is created based on data acquired by a procedure involving combination of data from a number of consecutive sensing means linear scans, and wherein the consecutive linear scans are acquired at consecutive moments in time, thereby enabling creation of a three dimensional representation of the hull. |
