A method for optically scanning, measuring and displaying a point cloud is provided. The method includes emitting, by a laser scanner, an emission light beam and receiving a reflection light beam that is reflected from an object. A control device determines for measurement points projected on a plane corresponding to a screen, wherein at least some measurement points are displayed on a display device. One or more pixels are gap filled to generate a visual appearance of a surface on the display device. Wherein the gap filling includes a first horizontal search in a first direction of a first measured point of the measurement points followed by a second horizontal search in a second direction of the first measured point. The gap filling further includes a first vertical search in a third direction of the measured point, followed by a second vertical search in a fourth direction.


A portable articulated arm coordinate measuring machine (AACMM) having an integrated camera captures 2D images of an object at three or more different poses. A processor determines 3D coordinates of a smoothly continuous edge point of the object based at least in part on the captured 2D images and pose data provided by the AACMM.

A three-dimensional (3D) measuring system and a method of determining a distance is provided. The 3D measuring system includes a display and an imager device. The imager device having a projector, a first camera and a second camera arranged in a predetermined geometric relationship, the first and second camera each having a photosensitive array with a plurality of pixels that transmit a signal in response to a wavelength of light. The projector projects a pattern that includes at least one element. The system further having one or more processors operably coupled to the display, the projector, and the first and second camera. The processors are responsive to computer instructions for determining a distance to the at least one element and changing an indicator on the display corresponding to the distance relative to a predetermined projector-to-object distance.


A method for measuring three-dimensional (3D) coordinates includes providing a retroreflector and a laser tracker. In a first instance, an operator gives a follow-operator command. The laser tracker responds by following movement of the operator. In a second instance, the operator gives a lock-on command. The laser tracker responds by steering a beam of light onto the retroreflector.


A method interactively displays panoramic images of a scene. The method includes measuring 3D coordinates of the scene with a 3D measuring instrument at a first position and a second position. The 3D coordinates are registering into a common frame of reference. Within the scene, a trajectory includes a plurality of trajectory points. Along the trajectory, 2D images are generated from the commonly registered 3D coordinates. A trajectory display mode sequentially displays a collection of 2D images at the trajectory points. A rotational display mode allows a user to select a desired view direction at a given trajectory point. The user selects the trajectory display mode or the rotational display mode and sees the result shown on the display device.


A method for scanning and obtaining three-dimensional (3D) coordinates is provided. The method includes providing a 3D measuring device having a projector, a first camera and a second camera. The method records images of a light pattern emitted by the projector onto an object. The 3D measuring device is moved from a first position and a second position along a second path. A gesture and a corresponding control function are determined based at least in part on the first position and the second position.


An articulated arm coordinate measurement machine is provided with a power supply having multiple power sources. The power supply having an input configured to receive electrical power from an external energy supply and first and second energy storage members. The first energy storage member having a first processing circuit configured to measure at least one first parameter and transmit a first signal to the first electronic circuit. The second energy storage member having a second processing circuit configured to measure at least one second parameter and transmit a second signal to the first electronic circuit. Wherein the power supply is configure to selectively transfer electrical power from at least one of the first and second energy storage members, the power supply further being configured to change the transfer of electrical power from the first and second energy storage members in response to the first signal and second signal.

A laser scanner collects gray-scale values and associated 3D coordinates of a scanned object in a spherical coordinate system, and displays reformatted gray-scale values that are reformatted from the spherical coordinate system into a planar view rectangular region. The reformatted gray-scale values have at least one straight line of the object appearing as a curved line on a display. The scanner enables selection of an angular range of measurement, measures gray-scale values and associated 3D coordinates in the spherical coordinate system over the angular range of measurement, displays the reformatted gray-scale values, the reformatted gray-scale values being the gray-scale values reformatted from the spherical coordinate system into a rectangular shaped region, the rectangular shape of the region extending and covering the angular range, and saves the reformatted gray-scale values and associated 3D coordinates on a storage medium, the associated 3D coordinates being 3D coordinates associated with the gray-scale values.


A method, system and computer program product are provided for displaying three-dimensional measurement points on a two-dimensional plane of a display screen having a plurality of pixels. The method includes projecting the measurement points onto the plane. Each of the measurement points is assigned to one of the pixels. A depth value is assigned to each of the pixels. A first pixel is selected having a first measurement point and a first depth value. A first side is searched for a second pixel having a second measurement point and a second depth value. A second side is searched for a third pixel having a third measurement point and a third depth value. It is determined whether the second and third measurement points are on a same plane. The first depth value of the first pixel is changed when the second and third measurement points are on the same plane.
