Patent number: 10732282Abstract: 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.Type: GrantFiled: October 12, 2017Date of Patent: August 4, 2020Assignee: Trimble ABInventors: Gregory Lepere, Guillaume David

Patent number: 8396681Abstract: A distance measuring measurement instrument and a method for such a station for scanning a surface or volume of an object are disclosed. The measurement instrument includes a position calculating circuit adapted to calculate position data including at least horizontal and vertical angle and distance between the measurement instrument and the object. A plurality of points in each of a number of subsets of a scanning area of the object during a measurement session and, at detection of a new point in the new subset, information related to at least one point having a corresponding location in at least one preceding subset is used, wherein the preceding subset being adjacent to the new subset.Type: GrantFiled: January 25, 2007Date of Patent: March 12, 2013Assignee: Trimble ABInventors: Set Svanholm, Grégory Lepere, Guillaume David, Fredrik Gylesjö, Sven Johansson, Björn Magnusson

Patent number: 8139203Abstract: The present invention provides devices and methods for multi-dimensional scanning of a scene. In particular, this invention provides scanning devices and methods employing controllable light beam scanning devices capable of sending a light beam onto a scene, and of receiving corresponding light returned from the scene, and controllers capable of operating the scanning device at selected beam orientations, and of gaining distance information from the scanning device at the beam orientations. The controller can dynamically define beam orientations using the distance information gained from preceding beam orientations.Type: GrantFiled: August 24, 2009Date of Patent: March 20, 2012Assignee: Trimble ABInventors: Grégory Lepere, Pascal Souffez
