3-Dimensional mapping of underwater surface for navigation using underwater ultrasonic piezoelectric transducer
MetadataShow full item record
In the era of modern technology, even today, the underwater surface perception and mapping is still a much vague subject. Many approaches have been carried out following the topic. In a third world country, like Bangladesh, where water body is very important part of communication, life gets hindered when visual aids are compromised during navigation. The thesis conducted works to design a system to perceive and map the underwater surface. An underwater ultrasonic piezoelectric transducer has been chosen depending on the range to be perceived. A module has been designed from scratch to excite the transducer via a microcontroller unit and supply distances for mapping of the underwater surface. A program has also been developed to map the distances into a terrain and hereby display the distances in the form of 3-dimensional surface.
