Description of the “Evaluation” View
Page 92
D 3D-View: The 3D-View visualizes the 3D data (see Chap. 3.10 ).
E Measuring toolbar: Use this toolbar to set various ROIs for the measurement (see Chap. 3.16.4 ,
3.16.5 and 3.16.6 ).
F 3D-View toolbar: Use this toolbar to configure the orientation of the coordinate system in the
3D-View (see Chap.
3.10 ).
G “Start measurement” button: Click on this button to perform a measuring operation, calculate
the measurement results and display the point cloud and measurement results of the currently
selected measuring program in the 3D-View.
H Results display: The measurement results of the currently selected measuring program are dis-
played. Here, you can select which measured values are to be made available later for calcula-
tion, OK/nOK assessment, logging and output (see Chapter
3.16.8 ).
I Status bar: Status and error messages are displayed in the status bar (see Chapter 8.1 ).
1 Input data: Use this selection field to select the input data for the program (see also Chap. 3.16.3 ).
2 - Mode: The following modes are available for sphere fit:
 Standard: All points which are inside the selection ranges are used for computing the
sphere fit.

Optimized fit: When this option is activated, an additional preselection of the points is
applied prior to the sphere fit in order to automatically discard outliers or points that do
not belong to the sphere. The points are selected such that the distances from the result-
ing sphere are less than the predefined threshold and such that the maximum possible
number of points is used. Therefore, only the points that best match the sphere are used
for the sphere fit.
 Fixed radius: If the radius of the sphere is well known, you may force the radius with this
option. Thus the computation of the position of the sphere is more precise.
-
Threshold: The threshold for the preselection of the points in case of an activated “Optimized
fit” option. Points that deviate from the sphere to a smaller degree than the threshold are used
for the sphere fit. A higher threshold means that more points are used for the sphere fit.
-
Radius: Here you may specify the radius of the sphere in case of an activated “Fixed radius”
option.
3 3D-View: The 3D-View shows the fitted sphere (yellow). The points that were used to calculate the
sphere are shown with a color gradient (“Colors” palette, see Chap.
8.4 ). The points that best
match the sphere are shown in green. The discarded points are shown in gray.
