Visual sensors for localisation

Source: Wikipedia Visual odometry

• Process of determining robot POSE by analysing the associated camera images
• Use sequential camera image to estimate the distance travelled

Applications: robotics, computer vision

Types

• Monocular cameras
• Stereo cameras
• RGB-D cameras

Provide rich visual information, but for that, higher computational cost

• stereo or triclops sytem to measure distance
• [+] possibly more intuitive (bc humans use vision), more info. is contained in a picture compared to to laser/sonar scans
• [-] computation intensive (traditionally, might be less of a problem nowadays), error prone due to changes in light
