Underwater Metal Detection Using Video Image Processing Techniques to Determine Location

A metal detector circuit was constructed and further development prepared it for underwater use.

A digital video camera was used to record the view of the bottom synchronously with the collection of the metal detector output.Digital video recorded the path and was subsequently captured using Nero Vision Express 2.0.0.22. It was then broken into frames using ACDSee6.0.Two programs were used for image processing: Drexel University’s program to mosaic the frames and Phil Torr’s program to find the optical flow. Images were correlated with thestored metal detector readings using elapsed time and graphed in Microsoft Excel to show the detection of metal and the visual image of themetal. Using the image processed frames and the metal detection readings the diver can then have a m

ap with detailed features and location of the metal detected.
