Abstract: We generally describe a detection system and a method for tracking a moving object. The detection system (101) comprises a sensor (102) which is configured to sense an event. The system further comprises a trigger detection module (108a) which is coupled to the sensor (102), wherein the trigger detection module (108a) is configured to identify the sensed event to be a trigger event. The system further comprises an imaging device (114) for imaging the trajectory of an object, and an imaging device control unit (112) for controlling the imaging device (114). The imaging device control unit (112) is coupled to the trigger detection module (180a), wherein the imaging device control unit (112) is configured to control the imaging device (114) in response to a trigger event being identified by the trigger detection module (108a).

Abstract: An electronic route navigation method is used in navigating an autonomous vehicle in a road network. In an implementation of the method a map is stored on at least one computer, and is sectioned into quads by a processor. The smallest size quads are grouped as base level quads. Extended area quads are defined to contain the area of a plurality of base level quads. Thereafter, a route along a road is calculated from a start point to a destination point. Further extended area quads on the map that do not contain the start point or the destination point are used for cross routing. In said cross routing only the road routes crossing the extended area quad leading from the start point to destination point are calculated.
