Abstract

The techniques and systems herein enable ghost object detection. Specifically, a reflection line indicative of a potential reflection surface between first and second moving objects is determined. If enough stationary objects are within an area of the reflection line, it is determined whether one or more of the stationary objects within the area are within a distance of a reflection point. An expected velocity of the second object is then determined and checked against a velocity of the second object. If the expected velocity is near the velocity, it is determined that the second object is a ghost object. By doing so, the system can effectively identify ghost objects in a wide variety of environments, thereby allowing for downstream operations to function as designed.
