A method for measuring and registering 3D coordinates has a 3D scanner measure a first collection of 3D coordinates of points from a first registration position. A 2D scanner collects horizontal 2D scan sets as 3D measuring device moves from first to second registration positions. A processor determines first and second translation values and a first rotation value based on collected 2D scan sets. 3D scanner measures a second collection of 3D coordinates of points from second registration position. Processor adjusts second collection of points relative to first collection of points based at least in part on first and second translation values and first rotation value. Processor identifies a correspondence among registration targets in first and second collection of 3D coordinates, and uses this correspondence to further adjust the relative position and orientation of first and second collection of 3D coordinates.

Using a two-dimensional scanner to speed registration of three-dimensional scan data

A dimensional measuring device includes an overview camera and a triangulation scanner. A six-DOF tracking device tracks the dimensional measuring device as the triangulation scanner measures three-dimensional (3D) coordinates on an exterior of the object. Cardinal points identified by the overview camera are used to register in a common frame of reference 3D coordinates measured by the triangulation scanner on the interior and exterior of the object.

Registration of three-dimensional coordinates measured on interior and exterior portions of an object

A method for measuring and registering three-dimensional (3D) coordinates by measuring 3D coordinates with a 3D scanner in a first position, measuring two-dimensional (2D) coordinates with a 2D scanner while moving from the first position to a second position, measuring 3D coordinates with the 3D scanner at the second position, and determining a correspondence among targets in the first and second positions while moving between the second position and a third registration position.

A three-dimensional (3D) forensic evidence system is provided. The system includes a noncontact measurement device operable to measure a distance from the device to a surface. A first camera is operably coupled to the noncontact measurement device, the first camera having a field of view. A light source is operably coupled to the first camera and operable to emit light onto the surface within the field of view. A processor operably is coupled to the first camera, the processor operable to execute computer instructions when executed on the processor for determining 3D coordinates of at least one point in the field of view based at least in part on the distance, and assigning at least one color value to the at least one point in response to determining an interaction of a predefined wavelength of light with a substance in the field of view.

A method and system for scanning and measuring an environment is provided. The method includes providing a three-dimensional (3D) measurement device. The 3D measurement device being operable in a helical mode or a compound mode, wherein a plurality of light beams are emitted along a first path defined by a first axis and a second axis in the compound mode and along a second path defined by the first axis in the helical mode. A mobile platform holding the 3D measurement device is moved from a first position. A first group of 3D coordinates of the area is acquired by the 3D measurement device when the mobile platform is moving. A second group of 3D coordinates of the area is acquired with a second 3D measurement device that with six-degrees of freedom (6DOF). The first group of 3D coordinates is registered based on the third group of 3D coordinates.

An inspection system for measuring an object is provided. The inspection system includes an entryway sized to receive the object. At least two non-contact coordinate measurement devices are positioned with a field of view being at least partially within or adjacent to the entryway, each of the at least two non-contact coordinate measurement devices being operable to measure 3D coordinates for a plurality of points on the object as one of the object or the entryway move from a first position to a final position. A pose measurement device is operable to determine the six-degree of freedom (6DOF) pose of the object. One or more processors are provided that register the 3D coordinates for the plurality of points from each of the at least two non-contact coordinate measurement devices based at least in part on the 6DOF pose of the object.

A method of determining machined characteristics of a surface with a camera system, the camera system operable to obtain six camera images. The camera images are formed by illuminating the surface with light at each of two different angles. After reflecting off the surface, the light is passed through a polarizer at each of three different angles.

The pattern of light being generated by a shape control element with each of the first pattern of light having a pattern pose. A first image is captured with a camera of the first pattern of light. The pose or shape of the pattern of light is changed using the shape control element. A pattern pose or shape information is determined from both images. It is determined that the second image is valid based on the pattern pose or shape information differing by more than predetermined measurement errors or the pattern pose or shape information differing less than predetermined measurement errors from values that are based on the control values transmitted to the pattern pose and shape control element.

A method and system of generating a two-dimensional map with an optical scanner is provided. The method comprises acquiring coordinate data of points in an area being scanned with a mobile optical scanner. A current 2D map from the coordinate data is generated. A copy of the current 2D map is saved on a periodic or aperiodic basis. At least one data registration error is identified in the current 2D map. The saved copy of the current 2D map from a point in time prior to the registration error is determined. A second data set of coordinate data acquired after the determined saved copy is identified. The second data set is aligned to the determined saved copy to form a new current 2D map. The new current 2D map is stored in memory.
