Review

• The ProblemMeasuring a surface area can be cumbersome.• Previous SolutionsThe conventional physical apparatus• Proposed Solution:The Optical Telemeter

High Level SchemaPlace 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 deviceDisplay data

Low Level Schema

210 mm

279.

44 m

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

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 EvaluationTest and deploy the proposed solution
