Software library for tracked ultrasound image acquisition, calibration, and processing.
Point set extractor (PointSetExtractor)

Extracts the tooltip positions of a selected tool (tpyically a stylus, but it can be any other tool) and saves it into a polygon file for visualization or further processing. Optionally it can show the pointset on the screen in 3D. It can be used for visualization of motion trajectories or for collecting a point cloud for surface reconstruction.

Examples

Output: points
