Odometry
Encyclopedia : O : OD : ODO : Odometry
Odometry is the study of position estimation during wheeled vehicle navigation. The term is also sometimes used to describe the distance traveled by a wheeled vehicle. Odometry is used by some track or wheeled robots to estimate (not determine) their position relative to a starting location. Odometry is the use of data from the rotation of wheels or tracks to estimate change in position over time. This method is often very sensitive to error. Rapid and accurate data collection, equipment calibration, and processing are required in most cases for odometry to be used effectively.
The word odometry is composed from the Greek words hodos (meaning "travel", "journey") and metron (meaning "measure").
Compare to Dead reckoning.
