Abstract:
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.
