Abstract
A method, system, apparatus, article of manufacture, and computer-readable storage medium provide the ability to merge multiple point cloud scans. A first raw scan file and a second raw scan file (each including multiple points) are imported. The scan files are segmented by extracting segments based on geometry in the scene. The segments are filtered. A set of candidate matching feature pairs are acquired by registering features from one scan to features from another scan. The two raw scan files are merged based on the candidate matching feature pairs
Claims14
A computer-implemented method for merging multiple point cloud scans, comprising:
- (a) importing a first raw scan file and a second raw scan file for a scene, wherein each raw scan file comprises multiple points;
- (b) segmenting the first raw scan file and the second raw scan file by extracting first segments from the first raw scan file and second segments from the second raw scan file, wherein the extracting is based on geometry in the scene;
- (c) filtering the first segments and the second segments
- (d) registering one or more of the first features to one or more of the second features to acquire a set of candidate matching feature pairs;
- (e) merging the first raw scan file with the second raw scan file based on the candidate matching feature pairs, to create a merged scan file.
A computer system for merging multiple point cloud scans comprising:
- (a) a computer;
- (b) a point cloud scanner communicatively coupled to the computer, wherein the point cloud scanner obtains a first raw scan file and a second raw scan file for a scene, wherein each raw scan file comprises multiple points;
- (c) an application executing on the computer that:
- (1) segments the first raw scan file and the second raw scan file by extracting first segments from the first raw scan file and second segments from the second raw scan file, wherein the extracting is based on geometry in the scene;
- (2) filters the first segments and the second segments;
- (3) registers one or more of the first features to one or more of the second features to acquire a set of candidate matching feature pairs;
- (4) merges the first raw scan file with the second raw scan file based on the candidate matching feature pairs, to create a merged scan file.
