A method of detecting dynamic events from sequential point scans

To distinguishing points on moving objects instantaneously (i.e. dynamic event points detection from the rest points measured by ranging sensors, at the minimal computation and latency)

• This invention proposes a method that can distinguish instantaneously points on moving objects from the rest points measured by ranging sensors. Based on this point-level detection, moving objects in a scene can be detected, recognized and tracked robustly and accurately

• •Robust the method can detect dynamic events caused by moving objects of different type, shape, size, and speed, ranging from moving vehicles, pedestrian, cyclist in the application of autonomous driving and traffic monitoring
• •Adaptability the method is adaptable to different types of ranging sensors, ranging from conventional multi-spinning LiDARs, emerging solid-state or hybrid LiDARs, 3D laser scanners, radars, to other ranging sensors.
• •Efficient the method is very efficient and can run at the point measuring rate (a few tens of thousands Hertz) on embedded low-power computers
• •Low-latency the method enables to detect if a point is a dynamic event immediately after its measurement, the latency from the measurement of a point on any moving object to its detection is below one microsecond

• Ranging sensors
• Moving objects detection
