Detailed Description

Implementation of the abstract relation scoring heuristic using a directord relation approach. Calculate direction vectors between simultaneously recorded object estimations in a pair of trajectories. Calculate angles between consecutive direction vectors. Calculate direction continuity as described in Meißner et al. 2013 in Sec. V. A.. Calculate average distance between object estimations (recorded at the same time) over the trajectory pair as well.

Member Data Documentation

double SceneModel::DirectionRelationHeuristic::mMaxAngleDeviation

private

Maximal allowed angular distance between two objects. It the distance is greater, we have a break in the relation between the two objects.

Definition at line 123 of file DirectionRelationHeuristic.h.

double SceneModel::DirectionRelationHeuristic::mStaticBreakRatio

private

Maximal percentage of breaks in object relation. If there are more breaks between the objects this candidate relation is ruled out.

Definition at line 111 of file DirectionRelationHeuristic.h.

double SceneModel::DirectionRelationHeuristic::mTogetherRatio

private

Minimal percentage of the time objects are related relation. Objects must be at least related for this percent of all frames.

Definition at line 117 of file DirectionRelationHeuristic.h.
