Calibrate Position" Measuring Program - MICRO-EPSILON surfaceCONTROL 3D Instruction Manual

Description of the "Data Preprocessing" View

5.1.1 "Calibrate Position" Measuring Program

Use the "Calibrate Position" program to correct tilting and displacements caused by the mounting posi-
tion of the sensor. You can rotate and move the point cloud and store the resulting transformation of the
3D points permanently in the measuring program. You can manually edit the values for the transfor-
mation or automatically determine the transformation values using a plane fit. By this the values are deter-
mined such that the fitted plane lies horizontally in the coordinate system and the center of gravity of the
fitted points is at the center of the coordinate system. Proceed as follows:
-
If applicable, select the input data for the transformation (see below, section "1" and Chap. 3.16.3).
- Manually entry of values:
 Enter the desired values for the rotation and translation (see below, section "2")
-
Automatic determination of values:

Activate the setup mode of the measuring program (see below, section "4"). A plane is then
fitted to the 3D points of the point cloud.

If necessary, limit the range for the plane fit in order to eliminate interfering points (see sec-
tion "E" and Chap. 3.16.4,

Click on the "Calculate values" button (see below, section "5"). The point cloud is aligned
such that the fitted plane lies horizontally in the coordinate system and the center of gravity
of the fitted points is at the center of the coordinate system.

Deactivate the setup mode (see below, section "4").

Display Elements and Parameters in the "Calibrate Position" Program
A "General" toolbar: Using this toolbar, you can select the data source (see Chapter
save and load parameters and reset selected parameters to default settings (see Chapter 3.17).
B List of active measuring programs: This section displays the active measuring programs from the
"Data preprocessing" group. You can add and remove measuring programs (see Chap. 3.13),
move them (see Chap. 3.14) and select an active measuring program for parameterizing and dis-
playing the measured values.
C Measuring program groups / Tab bar for switching between views: This tab bar allows you to
switch between the four main views (see Chap. 3.2). To the left of the tab bar you find the section
for adding, removing and selecting measuring program groups (see Chap. 3.15).
D 3D-View: The 3D-View visualizes the 3D data (see Chap. 3.10).
