  • Publication number: 20240069178
    Abstract: The present disclosure is directed to a method for determining a current position and/or orientation of a laser radar relative to an object by a computer. A camera system is attached to the laser radar. In the method, the position of the camera system is determined by obtaining one or more images of the object. At least three reference targets having a fixed spatial relationship to the target are observed in the one or more images. The relative spatial relationship and/or the position of the at least three reference targets on the object to each other is obtained from a storage. The position of the reference targets relative to the camera is calculated by using the relative spatial relationship of the at least three reference targets to each other and the observed spatial directions to said reference targets defined relative to a camera fixed coordinate system.

  • Patent number: 8874406
    Abstract: A system for measurement of spatial coordinates and/or orientation of a probe, comprising a first spatial direction sensor associated with a pattern of targets with known positions relative to each other and to the first spatial direction sensor, a second spatial direction sensor, and processing means for the computation of the orientation and/or spatial coordinates of the pattern of targets relative to the second spatial direction sensor based on the known positions of the targets relative to each other and a determination of the spatial directions of the targets with respect to the second spatial direction sensor, wherein at least three of the targets are in the field of view (FOV2) of the second spatial direction sensor irrespective of the orientation of the pattern of targets and wherein the first spatial direction sensor determines the spatial coordinates and/or orientation of the probe.

  • Patent number: 7145647
    Abstract: A system for measurement of spatial coordinates comprising a probing tool and a main measuring unit, wherein said probing tool comprises a reflective object element, observation mechanism located in a known position and orientation relative to said reflective object element and capable of observing targets; and wherein said main measuring unit comprises a distance measuring device capable of measuring a distance from said device to said reflective object element; a mechanism constructed and adapted to direct a measuring beam from said distance measuring device to said reflective object element; a direction determining mechanism constructed and adapted to determine a direction of a measuring beam; at least two targets located in known positions relative to said distance measuring device, whereby the orientation of said reflective object element can be determined from observations of said targets by said observation mechanism.

  • Patent number: 6389158
    Abstract: The invention relates to a system for determining spatial coordinates of points, wherein the system involves a fixed array of a network (2) of control points (3), and a manually or mechanically manipulatable measuring probe (1; 1′) containing at least one camera (9′, 9″, 9′″), and wherein the measuring probe (1; 1′) is designed for physical contact with a measuring point on an object (4) which is to be measured via a fixedly mounted contact unit (14) projecting from the measuring probe, which has a known, defined position in the coordinate system of the measuring probe; and a system unit (5) which computes the position of the contact unit (14) relative to a coordinate system defined by said control points (3) on the basis of the measuring probe's (1; 1′) image of the control points (3), and the known position of the contact unit (14) in the coordinate system of the measuring probe (1; 1′).
