Abstract

The Nikon Coolpix885® conventional digital camera is utilized to reform three-dimensional (3-D) turbulent pattern on lake that is situated in University Technology Malaysia (UTM).The main objective of this study is to use fuzzy arithmetic to reduce the errors arising from noise in digital camera data when constructing turbulent pattern flow. In doing so, the fuzzy B-spline algorithm, which assemble a global topological between the data points, are used to support an approximation to the real surface. Further, the fuzzy B-spline is performed to water surface information which estimated from 2-D digital camera images.

Key words: Digital camera, turbulent flow, fuzzy B-spline, three-dimensional (3D) reconstruction.
