The integral-free Kalman filters which are widely used in target tracking are studied. The algorithms of Unscented Kalman filter (UKF), Cubature Kalman filter (CKF) and Square-root cubature Kalman filter (SCKF) are compared in details. A modified algorithm (MSCKF) is proposed to optimize the performance. When considering different original ranges and radial speeds, simulation of linear motion targets...
This paper presents the methods for data processing technology of 3D points cloud with large unorganized and noisy point sets. Firstly, the noise points will be selected and deleted by the boundary points detection algorithm (BPDA). Secondly, we parameterize the interior points to the sphere model, the octahedron model and the geometry image model. Lastly, we give the error measure of the parameterization...
A Gaussian sum particle filter using RBF Neural Network (BRF-GSPF) is proposed to deal with nonlinear sequential Bayesian estimation. The nonlinear non-Gaussian filtering and predictive distributions are approximated as weighted Gaussian mixtures, and mixtures components are gotten by RBF neural network. This method implements conveniently in parallel way by cancelling resampling that solves weight...
