1. A method of laser-based speed determination, the method comprising:
- determining, by a processor via a digital scan of a field of view, a location of a target;
directing, by the processor via a laser-aiming device in communication with the processor, a laser from a laser device to the determined location of the target;
determining a speed of the target via light reflected from the target to the laser device;
wherein, during at least a portion of each of the determining the location, the directing, and the determining the speed, the target and a laser-based speed-determination system are each independently in motion relative to a fixed point; and
wherein the determining the speed comprises detecting and considering ground speed of the laser-based speed-determination system.

Abstract
A method of laser-based speed determination includes determining, via a digital scan of a field of view, a location of a target, directing, via a laser-aiming device, a laser from a laser device to the determined location, and determining a speed of the target via light reflected from the target to the laser device.

18. A laser-based speed-determination system, the system comprising:
-
a laser device; a laser-aiming device coupled to the laser device; a processor in communication with the laser device and the laser-aiming device, the processor being adapted to execute instructions to; determine, via a digital scan of a field of view, a location of a target; cause, via the laser-aiming device, a laser to be directed from the laser device to the determined location of the target; determine a speed of the target, the speed being determined via light reflected from the target to the laser device; wherein, during at least a portion of each of the determination of the location, the direction of the laser, and the determination of the speed, the target and the laser-based speed-determination system are each independently in motion relative to a fixed point; and wherein the determination of the speed comprises detection and consideration of ground speed of the laser-based speed-determination system. - View Dependent Claims (19, 20)
