ROBOT NAVIGATION USING CAMERA BY IDENTIFYING SIGNAGES

Computer vision is widely used in autonomous navigation, specifically in
recognizing objects or obstacles in its surrounding. Unique images of signage placed
at strategic location to give information for the directions pertaining to a desired path
plan. This study looks at the use of specific shapes of signage that can be used by a
mobile robot to autonomously navigate from one location to another. Camera
mounted on the mobile robot will capture image of the signage and later employed
edge-based contour detection algorithm to extract information from the signage.
Experiments have been conducted under different environments due to the signage’s
position that various from one experiment to another. The robot is able to navigate
itself from start to the end point by following the signages correctly with minimal
assistant. Data from ultrasonic sensor is used along with information from vision
system to explore the surrounding.
