Abstract

A system and method for providing feedback on a quality of a 3D scan is provided. The system includes a coordinate scanner configured to optically measure and determine a plurality of three-dimensional coordinates to a plurality of locations on at least one surface in the environment, the coordinate scanner being configured to move through the environment while acquiring the plurality of three-dimensional coordinates. A display having a graphical user interface. One or more processors are provided that are configured to determine a quality attribute of a process of measuring the plurality of three-dimensional coordinates based at least in part on the movement of the coordinate scanner in the environment and display a graphical quality indicator on the graphical user interface based at least in part on the quality attribute, the quality indicator is a graphical element having at least one movable element.

First claim

What is claimed is:

a coordinate scanner configured to optically measure and determine a plurality of three-dimensional coordinates to a plurality of locations on at least one surface in the environment, the coordinate scanner being configured to move through the environment while acquiring the plurality of three-dimensional coordinates; a display having a graphical user interface; and one or more processors configured to determine a quality attribute of a process of measuring the plurality of three-dimensional coordinates based at least in part on the movement of the coordinate scanner in the environment and display a graphical quality indicator on the graphical user interface based at least in part on the quality attribute, the quality indicator is a graphical element having at least one movable element.

2 . The system of claim 1 , wherein the size of the movable element is based on the quality attribute.

3 . The system of claim 1 , wherein the at least one movable element includes a plurality of stacked bars in the movable element.

4 . The system of claim 1 , wherein the graphical element further comprises a quality symbol, the at least one changeable bar indicating a first quality attribute, the quality symbol indicating a second quality attribute.

5 . The system of claim 4 , wherein:
the first quality attribute is based at least in part on the speed of the coordinate scanner, and the second quality attribute is based at least in part on a target attribute; and the target attribute is the age of the target.

6 . The system of claim 1 , wherein the graphical element further comprises a quality symbol, the one or more processors being further configured to change the quality symbol based on the quality attribute.

7 . The system of claim 1 , wherein the parameter is one of a length of the at least one movable element, a color of the at least one movable element, or a combination thereof.

8 . The system of claim 1 , wherein:
the graphical element is a first color when the process of measuring the plurality of three-dimensional coordinates with the coordinate scanner provides a density of the plurality of three-dimensional coordinates above a first threshold; the graphical element is a second color when the process of measuring the plurality of three-dimensional coordinates with the coordinate scanner provides the density of the plurality of three-dimensional coordinates below a second threshold; and the graphical element is a third color when the process of measuring the plurality of three-dimensional coordinates with the coordinate scanner provides the density of the plurality of three-dimensional coordinates being between the first threshold and the second threshold.

9 . The system of claim 1 , wherein the quality attribute is based at least in part on a translational speed of the coordinate scanner through the environment.

10 . The system of claim 1 , wherein the quality attribute is based at least in part on at least one of: a number of tracking targets; an age of the targets; a rotational speed of the coordinate scanner; a quality threshold of images used to track the coordinate scanner; a number of three-dimensional points acquired; a 3D geometry of the environment; a distance to the objects being scanned; and a level of noise in the plurality of three-dimensional coordinates.

11 . The system of claim 1 , wherein the graphical user interface includes a first portion and a second portion, the quality indicator being positioned in the first portion

12 . The system of claim 1 , wherein the quality indicator instructs the operator to perform a stationary scan.

13 . The system of claim 1 , wherein the quality indicator instructs the operator to perform an anchor scan.

14 . The system of claim 1 , wherein the quality indicator instructs the operator to record an anchor object.

15 . The system of claim 1 , wherein the one or more processors are further configured to determine when tracking has been lost, and displaying on the graphical user interface two overlapping transparent images of the environment.

16 . A method comprising
moving a coordinate scanner through an environment, the coordinate scanner being configured to optically measure three-dimensional coordinates; acquiring determine a plurality of three-dimensional coordinates to a plurality of locations on at least one surface in the environment with the coordinate scanner; and displaying on a graphical user interface of a display a graphical quality indicator on the graphical user interface based at least in part on the quality attribute, the quality indicator is a graphical element having at least one movable element.

17 . The method of claim 16 , further comprising changing the size of the movable element is based on the quality attribute.

18 . The method of claim 16 , further comprising displaying on the graphical user interface a quality symbol, wherein the at least one changeable element indicates a first quality attribute, the quality symbol indicates a second quality attribute.

19 . The method of claim 16 , further comprising displaying a quality symbol on the graphical user interface and chaning the quality symbol based on the quality attribute.

20 . The method of claim 16 , wherein the parameter is one of a length of the at least one movable element, a color of the at least one movable element, or a combination thereof.

21 . The method of claim 16 , further comprising:
changing the graphical element to a first color when the process of measuring the plurality of three-dimensional coordinates with the coordinate scanner provides a density of the plurality of three-dimensional coordinates above a first threshold; changing the graphical element to a second color when the process of measuring the plurality of three-dimensional coordinates with the coordinate scanner provides the density of the plurality of three-dimensional coordinates below a second threshold; and changing the graphical element to a third color when the process of measuring the plurality of three-dimensional coordinates with the coordinate scanner provides the density of the plurality of three-dimensional coordinates being between the first threshold and the second threshold.

22 . The method of claim 16 , wherein the quality attribute is based at least in part on at least one of: a number of tracking targets; an age of the targets; a rotational speed of the coordinate scanner; a quality threshold of images used to track the coordinate scanner; a number of three-dimensional points acquired; a 3D geometry of the environment; a distance to the objects being scanned; and a level of noise in the plurality of three-dimensional coordinates.

23 . The method of claim 16 , wherein the graphical user interface includes a first portion and a second portion, the quality indicator being positioned in the first portion
