Opdracht 2

This assignment aims at making a setup for taking specified images with a webcam and processing them in a certain way to achieve a certain goal. This assignment has to be done in groups of 2 students.

Setup

The final goal is to convert the above image into a "top" view.

Make the above setup on a simular scale, using the facilities of the ITT/SOS lab (HG 02.068).

Take a number of 640x480 images suitable to experimental determine the relation between Z and y, including some indication about the error.

Take further with that setup a number of 640x480 images (like the one on the right):

• with easy recognizable objects (not too small, uniform color different from the color of the floor and the wall behind, not overlapping)
• with a bit more difficult to detect objects, with more color and/or texture variation
• with some overlapping objects of different color

Assignment

• Derive the relation between Z and y from theory.
• Determine the relation experimentally.
• Develop and implement an algorithm to detect the objects on the easy images
• Test it our on the other images, observe the problems
• Describe the design of an algorithm to determine where we are interested in: the contact lines of objects with the floor.

Deliverables

• A 15 minutes presentation of what you have achieved
• A report

Notes

• There is a key procedure for the lab, give your name and student number to me
• Ask me or Harco Kuppens for any needed material
• Contact me for any questions you have.
• It is not forbidden to discuss this assigment amoung the groups.
