FH/FZ5 Processing Item Function Reference Manual
2 Specify on the image which four points
whose information to use for distortion
compensation.
3 Select "Figure" for the reference
position and click Edit.
4 On the image, specify which information
for the positions where the four
specified points should be to use for
distortion compensation.
When concrete coordinate positions are
known or to measure them and find accurate
positions, it is possible to set "Expression" and
substitute measurement values from other processing units.
5 Place a check at "Conversion image" in
the display settings and check the image
in which the distortion has been
compensated for.
Setting Example for when There Is Chatter in the Work
Even when there is chatter in the work during
transport and error is generated in the distance to
the camera, 4-point position information can be used
to compensate for distortion in the image.
Preset in other units so that when you specify the
p
o
sitions where the four points used for distortion
compensation should be as reference positions, the
4-point position information can be acquired.
Compensate for the distortion in the image so that the position information for the four points aligns with the
reference positions when measurements are made. With this setting, 3D position deviation can be compensated
for.
1 Select "Operation" for the measure
position and click Edit.
