Log sorting
![]() | ||
The system is based on Tordivel's standard and flexible Scorpion Vision Software platform and uses the latest available VISION-PC technology and components. The graphical user interface has a intuitive visual feedback. To reduce development time and increase system performance a color camera was chosen for image aquisition to enable the use of advanced colour segmentation algorithms. The system is easily adapted to both new and existing installations.
The system sorts the logs using the following criteria
Minimum and maximum diameter
Minimum and maximum length
Conical shape
If the log is bent
The amount of peel present on the log
