Abstract:
1. An object detection and behavior recognition system using three-dimensional motion data, comprising one or more processors and a memory, the memory having executable instructions encoded thereon such that upon execution of the instructions, the one or more processors perform operations of: receiving three-dimensional (3D) motion data of a scene from at least one sensor; identifying at least a first object in the 3D motion data; extracting an object track of the first object, the object track being indicative of object motion in the scene over time; recognizing a behavior of the first object based on the object track; instructions for causing the one or more processors to further perform operations of; identifying at least a second object in the 3D motion data; extracting an object track of the second object, the object track being indicative of object motion in the scene over time; normalizing the object tracks of each of the first and the second objects to generate first and second normalized object tracks; and comparing the first and second normalized object tracks to calculate behavior differences and generate behavior results indicative of relative interactions between the first and second objects.
