摘要： A system for tracking movable crane components to assist maneuvering the crane within a jobsite includes a computing device having a processor which calculates a 3D geospatial location and orientation of a 3D coordinate system for an upperworks that has an origin chosen along an axis of rotation between the upperworks and a lowerworks. The processor calculates a 3D position of the origin of the upperworks based on local coordinates and transforms the 3D position of the origin of the upperworks from the local coordinates to global 3D coordinates using absolute position sensing data from first and second positioning sensors attached to the crane (for instance on the upperworks and the hook, respectively) and using global 3D coordinates specific to the jobsite where the crane is located. The upperworks 3D coordinate system is useable to determine line segments in the upperworks 3D coordinate system for various movable components.

摘要： A method and a system for navigating a vehicle around a real site. The method comprises the following steps: (A) creating a database of Positional Reality Images (PRI) that substantially accurately represents the real site, and (B) accessing the database of Positional Reality Images (PRI) that substantially accurately represents the real site in order to navigate a vehicle around said real site. The integrated Positional Reality System (PRS) comprising a positioning system integrated with a plurality of optical systems is used to create the database of Positional Reality Images (PRI) that substantially accurately represents the real site. The PRS utilizes a laser-diode-based optical scanning system if a range between the PRS and a selected real site object comprises a short range distance and a pulse-type-microlaser-based optical system if a range between the PRS and a selected real site object comprises a short-to-medium range distance.

摘要： A three dimensional laser tracking and control system is disclosed. The system includes a laser beacon generating a three dimensional rotating and scanning laser beam that covers a three-dimensional area. Each mobile unit has identification number (ID) and is equipped with a intelligent reflector (IR). Each mobile unit uses its intelligent reflector (IR) to communicate to the signal system its ID and the time of illumination by the laser beam. The signal system calculates the three dimensional coordinates for each mobile unit and communicates the positional data back to each mobile unit using the same laser beam during the subsequent rotation cycles.

摘要： A number of laser beam stations emit vertically separated parallel planes and/or ray-planes of laser light that can be discriminated by their respective plane elevations, modulation of the laser light, time synchronizing, etc. Identifying the laser plane would also imply an identification of the source laser beam station, and thus a precise indication of the elevation at the point of optical intercept. Alternatively, a single laser beam station is used that can emit several different monochromatic color planes and/or ray-planes of laser light. Monochromatic laser diodes, for example, are used for point-light sources and rotating or on-end conical mirrors are used to convert the diode laser light to the required monochromatic color planes and/or ray-planes of laser light. Receivers, generally held on masts attached to motor grader, bulldozer, loader, and excavator machines are used to sense the vertical reference position of the monochromatic color planes and/or ray-planes of laser light, relative to the earth cutting blade of the machine. Fixed-color filters, color filter wheels, and/or linear array photodetectors are used to discriminate amongst the colors and to exactly sense the plane of intersection with the machine. The results of the sensing are either displayed to an equipment operator for manual adjustment of the blade to an automatic servo control system connected to hydraulically control the blade.
