Abstract: 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. A deviation in a measured parameter from an expected parameter is determined. The calibration of the 3D measuring device may be changed when the deviation is outside of a predetermined threshold.

Abstract: A method of balancing colors of three-dimensional (3D) points measured by a scanner from a first location and a second location. The scanner measures 3D coordinates and colors of first object points from a first location and second object points from a second location. The scene is divided into local neighborhoods, each containing at least a first object point and a second object point. An adapted second color is determined for each second object point based at least in part on the colors of first object points in the local neighborhood.

Abstract: A method for automatically generating a three-dimensional (3D) video of a scene by measuring and registering 3D coordinates at a first position and a second position of a 3D measuring device, the 3D video generated by combining two-dimensional images extracted at trajectory points along a trajectory path.

Abstract: 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.

Abstract: 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.

Abstract: 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.
