Abstract
Method and apparatus for scanning surfaces of a three-dimensional object employ a first sensor to acquire first data points and a second sensor to acquire second data points. The first sensor has a relatively lower accuracy and faster data point acquisition rate than the second sensor, and the second data points are assigned a higher weighting than the first data points. A three-dimensional coordinate point cloud is generated based on the both the first and second data points and their respective weighting.
Claims23
A method comprising:
- (a) scanning surfaces of a three-dimensional object with a first sensor to acquire first data points representative of surfaces that have been scanned with the first sensor, and adding the first data points to a three-dimensional coordinate point cloud;
- (b) scanning surfaces of the three-dimensional object with a second sensor to acquire second data points representative of surfaces that have been scanned with the second sensor, and adding the second data points to the three-dimensional coordinate point cloud;
- (c) wherein the first sensor has a lower accuracy and a faster data point acquisition rate than the second sensor, and the second data points are assigned a higher weighting than a weighting assigned to the first data points;
- and
- (d) basing the three-dimensional coordinate point cloud on weighted first and second data points.

- and
- (c) a module that collects the first and second data points, adds the first and second data points to a three-dimensional coordinate point cloud, and bases the three-dimensional coordinate point cloud on weightings of the first and second data points, with the second data points having a higher weighting than a weighting of the first data points.
