以下是一个可能的 trajectory_cleaning 函数的 Matlab 代码示例:
```matlab
function cleaned_traj = trajectory_cleaning(traj, threshold)
% TRAJECTORY_CLEANING Remove noisy points from a trajectory.
% cleaned_traj = TRAJECTORY_CLEANING(traj, threshold) returns a cleaned
% trajectory by removing points that are too far away from their neighbors.
% The input trajectory is a matrix with each row representing a point in
% 2D space (x, y coordinates). The threshold parameter specifies the
% maximum distance allowed between a point and its neighbor.
% Initialize cleaned trajectory with first point
cleaned_traj = traj(1,:);
% Loop through each point in the trajectory
for i = 2:size(traj, 1)
% Calculate distance between current point and previous point
dist = norm(traj(i,:) - cleaned_traj(end,:));
% If distance is smaller than threshold, add current point to cleaned
% trajectory
if dist <= threshold
cleaned_traj = [cleaned_traj; traj(i,:)];
end
end
end
```
这个函数接受两个参数:原始轨迹 traj 和阈值 threshold。函数返回一个清理过的轨迹 cleaned_traj,其中距离过远的点已经被移除。函数从第二个点开始循环,计算当前点与前一个点的距离。如果距离小于阈值,则将当前点添加到清理后的轨迹中。
