Justification Week - 17/04/15

This week, we were tasked to present and justify our choice of sensor which, me and my partner have decided to use a camera-based system.  What is available currently is the Mobileye 560 which has a list price of US$850.  This high price reflects the amount of features it has which include:

- Lane Departure Warning
- Pedestrian Warning
- Frontal Impact Warning

Other aftermarket options have no list price as they are priced upon seeing the application. Therefore using the 560 price as the basis for the average aftermarket lane departure system price example, the group has aimed to build the basic lane departure system at a price of up to $250. We were able to work out a base price for our unit excluding the sensor.  The main group components are as follows:

- Arduino Unit (Uno) - $50.00
- Arduino Housing - $20.00
- Wiring - $12.00
- Buzzer - $3.00
- Super Bright LED x6 - $4.56 @$0.76 each
- Universal Mini Housing (For the HUD) - $10.00

The total price comes to $99.56 for the base unit without the sensor.

Logitech C170

After considering the different sensors available, we have chosen the camera.  A basic Logitech C170 webcam will cost $28.00 brand new and features a 1024x768 video resolution.  This would take the unit total cost to $127.56 which is a little over half of the maximum budget. The choice of this camera was due to the need to have a cost effective camera that can provide responsive and accurate video to be able to pick up lane markings.
