2. Need Analysis
• 41% of the total traffic accident casualties are
due to abnormal lane changing.
• More than 535 pedestrians die in road
accidents every year.
• Pune City has the highest rate of accidents
amongst 27 other cities in the India.
• Need for cost effective life saving tool.
• Easy to install in any locomotive.

3. Introduction
• Video-based car navigation systems are
emerging as the next generation technology.
• Object information is gathered via cameras
and then, feature extraction is performed to
obtain edge, colour, object details.
• We are developing a system which comprises
Pedestrian Detection System(PDS) and Lane
Detection and Warning System(LDWS) for
Medium-Class Cars Worldwide.

4. Overview (LDWS)
Input image
Selected lane and position
Indicator on screen
1. A novel technique is used to recognize lane for a various road and
illumination, lane markings conditions such as damaged road surfaces blocked
by a car, shadow, backlights, etc.
2. The basic transform used will be HOUGH transform along with the
segmentation of image concept to detect the lanes without any errors or
flaws.

5. Overview

6. Overview (PDS)
• To achieve high detection speed
with good detection performance,
a Two-step framework method
was proposed.

• Hough Transform
Used for Classification

10. Pedestrian Detection
• 2 Step Method

11. Pedestrian Detection Contd.
• Haar like features
• Triangular Feature Set
• Edgelet
• Shapelet
