Mounting and reflection prevention
LBC 65x/64x/63x/621
In order to avoid reflections from the glossy surfaces to be scanned, the device is usually
tilted so it is not perpendicular to the surface, unless you want to use the effect of direct
reflections. When camera is tilted, the image is slightly distorted and may result in worse
performance when certain inspections are performed (i.e. Object Locator). Image
rectification can be used to correct the effect of perspective distortion, please find
subsection 4.6.7 on how to perform picture calibration rectification
. Typical values are
between 10° and 20°. When using a polarizing filter, the recommended angle is 0°.
Figure 6 Typical values for LBC 65x/64x/63x/621
You may use a polarizing filter to minimize reflection effects on the image,
see
subsection 7.1
