This chapter presents Kalman filters for tracking moving objects and their efficient design strategy based on steady-state performance analysis. First, a dynamic/measurement model is defined for the tracking systems, assuming both position-only and posit
2 Filter Concept 将加速度,角速度,磁感应强度作为输入,刚体的方向作为输出。 状态向量由方向\mathbf{q}和角速度\vec{w}组成。四元数用来表示方向需要是单位四元数,自由度为3.四元素的四个组成将不在是独立的,这个和传统kalman滤波器的概念(各分量无关)不太一样。
Before showing the use of Kalman filter, let us first examine the challenges of tracking an object in a video. The following video shows a green ball moving from left to right on the floor. Get Copy Code Block showDetections(); The white region over the ball highlights the pixels detected...

tracking a physical object in a Cartesian coordinate system. The tracked object may move with either constant velocity or constant acceleration. The statistics are the same along all dimensions. If you need to configure a Kalman filter with different assumptions, use thevision.KalmanFilterobject ...

These oversimplified modeling assumptions can lead to significant reductions in tracking precision. To address this, we propose a GRU-based MOT method, which introduces a learnable Kalman filter into the motion module. This approach is able to learn object motion characteristics through data-driven ...
