An annotation device receives 4D sensor data representative of a first scene and that includes a point representative of a human limb in the first scene. The annotation device also receives 4D data representative of a second scene that includes points representative of a feature in the second scene. In addition, the annotation device generates a first tree data structure representative of occupation by the human limb in the first scene based on the point and a second tree data structure representative of occupation of the second scene based on the plurality of points. The annotation device maps the first tree data structure and the second tree data structure to a reference frame. The annotation device determines whether a tree-to-tree structure intersection of the feature and the human limb exists within the reference frame and annotates the feature based on the tree-to-tree structure intersection.
