1.2. OBJECTIVES
- Build a system that aids people with visual impairments in their navigation in certain paths.

- Light and easily wearable prototype.

- Free-hands system.

- Real-Time operation to ensure safety.

- Easy to use (no previous knowledge required).


Project's Motivation:
Using technology in order to aid people with impairments to get a high life quality (increase their independence).
Real-Time processor and FPGA in a single chip.
This allows to create custom hardware circuitry with high flexibility and to achieve a high performance.
Ideal for an embedded control system based on artificial vision
Webcam
Earphones
Rechargable battery
Charger
Highly productive environment for creating custom applications that interact with real-world data.

1.3. MAIN STEPS
1. Image's edges are extracted.
2. Lines defining the path are found.
3. Vanishing point is calculated.
4. Control is performed based on VP position.
5. Action to be taken is communicated via audio to the user.
Budget estimation:
Commercial and industrial prices are considered and no taxes are taken into account.

Thanks for your attention!
Replace the webcam with sunglasses with integrated camera. Wireless and with speakers on its sideburns.
Implement all the image processing block in the FPGA for increasing fps rate.
Use myRIO Wi-Fi capabilities for monitoring in RT location and position of the user.
Results after step 4:
Image's edges have been extracted, path's borders detected and vanishing point calculated.
