NavCam is a project aimed to help visually impaired people crossing busy intersections.
Planned main features are:
- Detection of some roadsigns (mainly useful for pedestrians);
- Detection of red traffic lights;
- Detection of moving vehicles in front of the camera;
- Sound announcements of warnings and prohibitions.
Basic approach to detection is hue-based segmentation, contour detection and recognition.
Project is built against Android 2.2 (Froyo) currently and is using OpenCV 2.4.2 for image processing.
