20100085579 | METHOD FOR TARGET TRACKING, AND ASSOCIATED TARGET - A method for determining rotational position of a target in a target tracking System is disclosed. The target comprises a plurality of light emitting elements arranged circumferentially around the target. The target tracking System further comprises a tracker unit capable of detecting light emitted by said light emitting elements. The method comprises the Steps of emitting from said light emitting elements an omni-directional synchronization signal; detecting in the tracker unit said synchronization signal; activating said light emitting elements sequentially starting from a reference direction, wherein each light emitting element is activated for a predetermined time and emits light during the time it is activated; detecting in the tracker unit a time when a maximum amount of light is received from the target; and calculating the reference direction for the target relative to a coordinate System based on the time interval between detection of the synchronization signal and the detection of a maximum amount of light received from the target. An active target for use in the method is also disclosed. | 04-08-2010 |
20100107429 | TARGET FOR USE IN MEASURING AND SURVEYING APPLICATIONS - One embodiment of the present invention concerns a target for use with a measuring instrument in distance measuring and surveying applications. The target includes a base element, at least one light reflecting area arranged at the base element, the at least one light reflecting area being arranged to reflect light beams being incident in an angular area of substantially 360° degrees in plane, and an identification unit arranged at the base element and being adapted to emit signals having predetermined characteristics, wherein the predetermined characteristics may be used to identify the target. | 05-06-2010 |
