Review The Problem Measuring a surface area can be cumbersome. Previous Solutions The conventional physical apparatus Proposed Solution: The Optical Telemeter

High Level Schema Place a marker on the surface area Take picture Send image to server Image pre- processing Determine region of interest Locate marker Determine dimensions of surface area Send computed data to device Display data

Low Level Schema 210 mm mm

Low Level Schema - Template Matching

Low Level Schema - Edge Detection Breadth Height

The User Interface A brief overview of the GUI – The user takes a picture of the surface area – Has an option of rejecting the image or taking another one – Save the image – Sends the image to the server

The User Interface 1. The Application start screen Starts app

The User Interface 2. The First Menu Screen Camera

The User Interface 3. The Camera Takes Picture

The User Interface Swipe left : Opens Menu Swipe right: Shows Results 4. Workspace

The User Interface Swipe Left Show results Camera, overwrites current picture

The User Interface The results page

Project Plan Term 1 – User Requirements and Analysis - Learn how to use OpenCV in order to manipulate images - Do research regarding image pre- processing techniques - Document Requirements Term 2 – Design and Development of the Prototype - Design the proposed solution - Develop a prototype of the proposed solution Term 3 – Coding the Final Application/Implementation - Add functionality to the Prototype hence improving it as a whole - Cater for shortcomings of the application Term 4 – Testing and Evaluation Test and deploy the proposed solution Optical Telemeter Timeline
