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

16. A laser-based speed-determination system, the system comprising:
-
a laser device; a laser-aiming device coupled to the laser device; a processing device in communication with the laser device and the laser-aiming device, the processing device 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; a display device in communication with the processing device; wherein the processing device is operable to execute instructions to display an annotated field of view on the display device, the annotated field of view comprising the field of view and the determined speed of the target; wherein the target comprises an automobile; wherein, during at least a portion of each of the determination of a location, the causing to be directed, and the determination of a speed, the target and a laser-based speed-determination system comprising the processing device and the laser-aiming device are each independently in motion relative to a fixed point; and wherein the determination of a speed comprises detection and consideration of ground speed of the laser-based speed-determination system. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
