Abstract: The present invention discloses a remote monitoring method based on information fusion and virtual reality for a marine engine room, comprising five step s: step 1: employing sensors to collect thermodynamic parameters; step 2-1: using normalized relative deviation analysis method to obtain symptoms of the thermodynamic parameters; step2-2: using multi-scale time domain averaging method to extract signatures of vibration & noise signals; step 2-3: using projection moment method to describe dynamic characteristics of static pictures and infrared thermal images of equipment in the engine room; step 3: extracting features in the performance parameters and infrared thermal images; step 4: transmitting the analyzed results; and step 5: establishing visual 3D scenes of the marine engine room. The method rebuilds 3D interactive scenes of the marine engine room and realizes 3D animation effectively.

Abstract: A remote monitoring method based on information fusion and virtual reality for marine engine room is disclosed, which comprises five steps: information acquisition; data analysis; feature extraction; data transmission; 3D scenes establishment. This method can monitor not only the conventional working parameters of main equipment in marine engine room, but also static pictures, infrared thermograms, vibration & noise signals, which can monitor accidents in engine room and enhance operators' awareness of autonomous ships; 3D interactive scenes of marine engine room are built and displayed through visual interfaces, which can make up for the lack of operators' attendance in future unmanned ships.
