Revision 1.6

Back to VTube-LASER

The end scan procedures in VTube-LASER are now enhanced to detect and remove outlier points in an end-scan.

In the context of VTube-LASER, an "outlier" is a point that falls outside the space of the actual surface being scanned.

The image at the right shows a side view of the result of an end-scan of a tube. The LLP (laser line probe) is positioned above the tube at the top of this image and is pointed downward in the direction of the left black arrow. The laser is moving downward along its path from the probe. It is then reflected back to the receiver of the scanner in the path of the right arrow.

Most of the points fall on the surface of the outside of the tube, inside the tube, or wall of the tube. However, there is also an outlier point present (enclosed in the red lines at the top). It cannot possibly part of the diameter. (These points were formed from a higher-than-normal reflective points on the inside of the diameter.

The outlier point is detected and then removed from the list of possibilities automatically because it is not close enough to the diameter or wall of the diameter.

This ensures repeatability of the end-scan process.

Using ball probe measurements on the end scans and and laser measurements in the cylinder straights now offsets the ball radius point properly in every case.

In previous versions, the part name was used as the filename only if the previous filename was empty.

In previous versions, the linear units radio buttons were not reliable in setting the proper state.

Plus they were too small to easily press.

This version removes these radio buttons and uses an large button with either an M or an I that toggles the state.

New Interface:

In previous versions, VTube required the operator to enter Measure Setup at least one time when coming into Laser Mode in order to setup the Laser active mode.

• The report window now requires an operator to close the window before using any other part of VTube.

• The print preview window buttons are re-arranged so that they are larger and easier to press. The Print button is moved to the right side of the window.

• If VTube changes from cylinder fit to centerline projection mode during a measurement, VTube will now always consider the measure a cylinder fit failure.

• See VTube-STEP v1.59 for changes to the STEP mode in this version.

• No known issues
