Visual odometry is a new navigation technology using video data. For long-range navigation, an intrinsic problem of visual odometry is the appearance of drift. The drift is caused by error accumulation, as visual odometry is based on relative measurements, and will grow unboundedly with time. The paper first reviews algorithms which adopt various methods to suppress this drift. However, as far as...
Advanced robot's navigation system based on GPS/INS is established in order to meet its working surroundings and taskpsilas demand. Centralized open-loop Kalman filter is applied in the navigation system. GPS/INS devices' output difference is the filter's input. The position-velocity integrated measurement equation is deduced based on the robotpsilas locomotion performance and measurement demand....
