Point cloud measurements

Page 25 of 68

In the lower table of the window, the old and new parameters from the 

instrument posi-

tioning information

 are listed. The following columns are available:

Old value

Parameter value of the original instrument position.

New value

Parameter value of the recalculated instrument position.

Delta

Difference between the new and the old parameter value.

Accuracy (1 sigma)

Accuracy derived from the resection calculation.

Calculation status

The calculation status column provides information about the pa-

rameter. If the accuracies are within the required tolerance, the

status is 

Ok

.

The repositioning functionality recalculates the point cloud points and replaces the parameters

of the point cloud position as displayed in the lower table of the wizard step 3.

The workflow for reposition with sphere targets is mostly identical to the point cloud

position with checkerboard targets. The default sphere target radius is 5 cm (Amberg

Sphere Target). The radius for the sphere can be changed for every point cloud in the

Property window

.

The center of the checkerboard targets used on the control points should have the same

center coordinates like the absolute coordinates of the control points used with prisms

targets.
