The objective of the project is to prove the feasibility of a new concept for an oceanographic imaging system in coastal zones (depth 500 kHz, resolution < 0,2o) and a low light level CCD camera (sensitivity 2VaJcm2). The sonar provides directly the distances, and a dynamic stereo vision process has to be done with the camera to extract the 3d range map. To improve the reliability of the sensors’ observations and the accuracy of the 3d range maps, the multisensor data fusion will be performed under the control of a Knowledge Based System depending upon the application.
