Linearized error propagation in odometry
NettetAlthough odometry is nonlinear, it yields sufficiently to linearized analysis to produce a closed-form transition matrix and a symbolic general solution for both deterministic NettetIn the case of automated guided vehicles using odometry, a very important issue is to know the actual rolling radius of the wheel used to calculate the position of the vehicle. This radius is not constant. Its changes depend on the elastic deformation of the band layer and wheel slip. The theoretical determination of the value of the radius and the …

Nettet1. aug. 2010 · Abstract. A new application for accelerometers is presented and evaluated instead of using it to measure the linear acceleration of the vehicle, which is usually performed with traditional odometry. In the present case, a dual orthogonal axis accelerometer is vertically aligned in the center of a wheel. Nettet3 IMU Propagation Model As seen in (5), to analyze the observability properties of the MSCKF’s linearized system model we must have an expres-sion for the error-statetransitionmatrix,Φi. In previousworkon inertial navigation,the discrete-timeerror-statetransition matrix for the IMU state has been computed in a number of ways.
