    摘要： A method for automatically grading a worksite using a grading vehicle may include receiving sensor data associated with detecting a light beam emitted from a light-emitting device positioned at the worksite, wherein the sensor data is received from at least one sensor installed on the grading vehicle. In addition, the method may include determining a relative horizontal distance between the grading vehicle and the light-emitting device based on the sensor data and determining a relative worksite position of the grading vehicle at the worksite based on the relative horizontal distance. Moreover, the method may include actively adjusting a position of a grading implement of the grading vehicle based on the relative worksite position of the grading vehicle to allow the worksite to be graded as the grading vehicle is moved relative to the light-emitting device across the worksite.

    摘要： 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.

    摘要： A construction apparatus (12) and method of controlling a construction apparatus from a laser source (38) made up of a substantially non-rotating beam (56). The construction apparatus includes a body (14), a construction tool (16) adapted to move material, a support moveably supporting the construction tool from the body and a control for guiding movement of the construction tool. A control is provided including a camera (28) that is adapted to capture an illuminated image that is derived from the laser source. The control determines direction information of the illuminated image with respect to the apparatus at least in part from an output of the camera. The control is further adapted to determine separation information of the spot with respect to the body and a physical relationship between the construction tool and the illuminated image. The construction tool (16) can be guided with respect to the illuminated image as a function of the direction and separation information and the physical relationship between the construction tool and the illuminated image.
