Then, the equality constraints of the feature points are added to the filter scheme to increase the measurement information. In the case where there is a loss of data, that is, the feature points are lost partly, and the predicted values of the lost points are estimated as the true value...
[MSCKF] A Multi-State Constraint Kalman Filter for Vision-aided Inertial Navigation 这篇06年的文章提出了一种新的几何约束,将3D feature的位置信息从卡尔曼滤波中的观测模型中去除,从而减少计算复杂度。 Related works the main limitation of SLAM is its high computational complexity; properly treating these...
Develops an analytic method of incorporating state equality constraints in the Kalman filter which is used to estimate the states of a dynamic system. Disadvantages of the state equality constraints approach during Kalman filtering; Considerations that indicate against the use of perfect measurements in ...
FILTER 3.1 Equality constraints Consider the following nonlinear process model and measurement equations, x k =f(x k−1 ) +w k−1 , y k =h(x k ) +ν k where f and h are nonlinear vector valued func- tions and w k and ν k are iid Gaussian noise processes distributed according...
