Abstract

The present invention provides a method for providing feedback to a user during a 3D scanning session and guides the user to finish scanning completely.

Claims

1. A method of determining the progress of a 3-dimensional scan of an object comprising the steps of:

a) providing a dummy model approximating in shape to the object being scanned and comprising a 3D point cloud with a normal in each point;

b) selecting keyframes from the 3-dimensional scan that are used for surface reconstruction;

c) determining whether a point in the 3D point cloud has been scanned from each of the selected keyframes; and

d) calculating the percentage of scanned points to the total number of points in the 3D point cloud.

2. The method of determining the completeness of a 3-dimensional scan of an object comprising the steps of

a) providing a dummy model approximating in shape to the object being scanned and comprising a 3D point cloud with a normal in each point;

b) selecting keyframes from the 3-dimensional scan that are used for surface reconstruction;

c) determining whether a point in the 3D point cloud has been scanned from each of the selected keyframes; and

d) providing information on what part of the object needs to be scanned so as to scan points in the 3D point cloud that have not been scanned.
