A point layout system is described that identifies points and their coordinates, using laser transmitters that are attached to at least three base units. The laser transmitters rotate about the azimuth and emit vertical laser planes. After being setup using control points, the projection lines of the laser planes will intersect on the floor of a jobsite at any point of interest, under command of the user with a remote unit. Once the first two base units are registered with the virtual floor plan, the third base unit can be automatically setup, using an automatic procedure that creates alignment axes with the first two base units. Once all three base units are registered with the floor plan, any one of the three base units can then be moved to a new physical location on the jobsite floor, and the automatic setup routine can be used to register its new position.
Methods and apparatus are provided for measuring distance from an instrument origin to each of a plurality of points in an environment. Laser pulses are emitted along a measurement axis at successive displacements about the origin. The emission time of each pulse is time-shifted relative to a fixed rate. The time shift corresponds to an index of a repetitive sequential pattern. Received pulses are detected at respective arrival times. For each received pulse: a current apparent distance is determined, a measured delta distance is calculated, a range interval is assigned by comparing measured delta distance with an expected delta distance synchronized with the index of the latest emitted pulse, the current apparent distance is defined to be a true measured distance for any received pulse assigned to a first time interval, otherwise the current apparent distance is defined to be a false measured distance.

METHOD OF SOLVING INITIAL AZIMUTH FOR SURVEY INSTRUMENTS, CAMERAS, AND OTHER DEVICES WITH POSITION AND TILT INFORMATION
A method for solving the initial azimuth for a survey instrument, and other devices, with position and tilt information. The method may be part of bundle adjustment performed during the processing of image and position data collected from each camera of a survey instrument. The use of the initial azimuth generation method (and initial azimuth generator) makes it possible to get accurate azimuth orientation of a camera, such as each camera of a multi-camera survey instrument, without using data from a compass-like sensor. The initial azimuth generated by this method can then be used in later steps/processes of the bundle adjustment to find tie-points with an automatic tie-point finder. Prior to this method, the automatic tie-point finding algorithm relied on the compass and its accuracy, and inaccurate compass values would cause a complete failure, slow runtimes, or less accurate results for the bundle adjustment.

Compensated distance measurement methods and apparatus
A transmit light signal is emitted toward a target at an emission time. An optical subsystem of a receiving system receives a return light signal which is converted to a return electrical signal. At least one attenuator applies an attenuation to at least one of the return light signal and the return electrical signal. The attenuation varies, as time passes, after emission of the transmit light signal, according to a time-dependent attenuation function such that the attenuation is maximum at a critical time elapsed since an emission time of the transmit light signal. The critical time is dependent on at least one geometrical parameter of the optical subsystem. A receive time is determined from the return electrical signal. The emission time and the receive time are used to calculate a measured distance.
