Description
"Intensity clipping" = 4%
"Intensity clipping" = 70%
Peak selection mode
(see par.
Max intensity
The algorithm for determining the peak brightness in the image
column to obtain the profile point. It is used to suppress false
images resulting from multiple reflections on complex profiles.
Modes:
Max intensity – Selecting the peak with the greatest
brightness.
First – Selecting the first peak in the column above.
Last – Selecting the last peak in the column above.
#2…#4 – Selecting the peak in the column above with the
corresponding number.
Detection threshold, %
10
This parameter determines the profile detection level. Increasing
this parameter makes it possible to reduce the effect of image
noise caused by, for example, ambient light. Range of values:
0...100%. If the value is 100%, the image is not processed.
Peak width, pixels
0...15
Peak brightness width in pixels. Range of values: 0...15.
19.1.1. "Peak selection mode" parameter
The
Peak selection mode
parameter defines the algorithm for detecting the
brightness peak in the column of the CMOS sensor to obtain the profile point. Changing this
parameter helps to correctly extract the profile in the case of laser beam re-reflections from
the object surface or in the case of brightening from external sources of optical radiation.
The intensity of the re-reflected beam or brightening from external light sources can
sometimes exceed the intensity of the laser line. In this case, you can use the modes with an
indication of a more specific detection point.
Example:
Re-reflections of a laser beam on the object having a complex profile.
