Determine the dimensions of objects of unknown submersible in water

Abstract

The measuring systems of dimensions of the immersed objects in water that base on the using of the digital camera are widely spread nowadays, especially in the robotic systems, because they are easy to install, fast, safe, inexpensive, and sufficiently accurate as compared with other complicated measuring systems that using the laser or electromagnetic sensors. This study deals with using a digital camera to determine objects ranges and dimensions of under water. In this study, we were able to find the dimensions of the target of under water at different angles and different heights of the water and all of these results were completed using the program Matlab.
