摘要： According to one embodiment, a three-dimensional (3D) measuring device is provided. The 3D measuring device includes a processor system that is configured to generate a point cloud representing multiple surfaces. The point cloud includes multiple scan points. Generating the point cloud includes receiving spherical coordinates for a scan point, the spherical coordinates comprising a distance (r), a polar angle (θ), and an azimuth angle (φ). Generating the point cloud further includes homogenizing a scan point density of the surfaces by filtering the scan points. The homogenizing includes computing a value (p) for the scan point based on the spherical coordinates. Based on the value exceeding a predetermined threshold, storing the scan point as part of the point cloud, and based on the value not exceeding the predetermined threshold, discarding the scan point.

摘要： A system and method for measuring three-dimensional (3D) coordinate values of an environment is provided. The system includes a movable base unit a first scanner and a second scanner. One or more processors performing a method that includes causing the first scanner to determine first plurality of coordinate values in a first frame of reference based at least in part on a measurement by at least one sensor. The second scanner determines a second plurality of 3D coordinate values in a second frame of reference as the base unit is moved from a first position to a second position. The determining of the first coordinate values and the second plurality of 3D coordinate values being performed simultaneously. The second plurality of 3D coordinate values are registered in a common frame of reference based on the first plurality of coordinate values.

摘要： A system and method for measuring three-dimensional (3D) coordinate values of an environment is provided. The system includes a movable base unit and a 2D scanner. A 3D scanner is coupled to the base unit, the 3D scanner measuring 3D coordinates and grey values of surfaces in the environment, the 3D scanner operating in either a compound or helical mode. Processors perform a method comprising: causing the 3D scanner to measure a first 3D coordinate values while operating in one of the compound or helical mode as the base unit is moved from the first to the second position; causing the 3D scanner to measure a second 3D coordinate values while operating in compound mode when the base unit is stationary between the first and second position; and registering the first 3D coordinate values and second 3D coordinate values into a single frame of reference.
