Nation Sun Yat-sen University, Institute of Under Sea Technology has sidescan equipment. The sidescan¡¦s graphic recorder uses thermal printer to record reflection data. Although thermal printer is convenient, it is difficult to archive and analyze data. Sidescan manufacturer also provide digital display and data storage equipments, but those equipments are expensive, and does not support development tools. It is not suitable for further research and development of sidescan sonar image processing algorithm. For this reason, we develop own sidescan digital image acquisition system. The new sidescan digital image collection system can provide sidescan digital image data, GPS data (include Longitude, Latitude, and GMT).
Research methodology¡G
(1) Measure sidescan¡¦s analog signal output characteristics.
(2) Develop controlling programs to collect digital image data from general purpose ADC (Analog to Digital Converter) Card.
(3) Test in Laboratory and under the sea
This sidescan equipment can display and store digital data in real time, and more functions like switch scan automatic, etc now. The digit data include right side 1024 sample points, left side 1024 sample points, GPS data (include Longitude, Latitude, and GMT).
