Shading Correction (Device Dependend) - Baumer VeriSens ID Series Technical Documentation Manual

10.2.14 Shading correction (device dependend)

Uneven lighting can result in some areas of the image being darker than others.
Shading correction provides the option to compensate for brightness irregularities in the image.
Performing shading correction
1. Use the Image recording tab to first configure the lighting situation as it will be for the planned feature
checks. Activate the internal lighting, for example.
2. Place an homogeneous white or grey template in the Vision Sensor's field of view. Any image display
options, such as a preset rotation, will be ignored.
3. Press the Teach button.
 Shading correction will be performed. The teaching of shading correction is performed on the
original sensor image and is applicable with or without distortion correction.
4. The gain factor for the individual image areas will be displayed in the preview window for the original
sensor image.
