OPTICAL RULER

TECHNOLOGY :

THE PROJECT IS ABOUT FINDING THE DISTANCE OF AN OBJECT USING A LASER PEN AND AN ORDINARY WEB-CAM.

HARDWARE REQ. : LASER PEN AND WEBCAM.

SOFTWARE REQ. : VISUAL STUDIO 2010, C# , .NET , AForge.

PROBLEM DEFINITION:

The project is about finding distance of an object by simply focusing the laser light on it. This application can be widely used in robotics and in the defence system.

We need to arrange the laser pen exactly below the web cam so that it's parallel to optical axis of camera's lens.

h' / h = f / D

h': height of laser image from center

h: height of laser beam from camera

f: focus of camera

D: the required distance

So D = (f * h) / h'

DELIVERABLES:

INPUT : Image formed by the laser on the object.

OUTPUT : Distance of the object from the web-cam.

ROLL NO.
