VTube-LASER Spike Filter

Laser stripes from the FARO are composed of a string of points in space. This filter automatically removes outlier vertex spikes in cylindrical laser stripes. An outlier is detected when the angle between any three adjacent points exceeds a user-entered value. The default value is 15 degrees.

Laser Stripes On Cylindrical Tube Shapes

Each stripe of points returned from a normal tube straight contains that are ordered with a slight curve like is shown here. With this formation of points, there is a natural tendency for any three adjacent points to form a slight angle. No matter which way the operator positions the scanner on the tube, the angles between these points should never climb above a certain value. The only case where this isn't true on a cylinder is if the cylinder contains deformations like pits and raised bumps.

Cylinder Laser Spike Filter

When measuring highly reflective tube, the points returned from the part of the diameter may spike away from the diameter in any direction. This filter recognizes that possibility and removed any data that spikes away from the curve before it is given to the math engine.
