WP 4 – Multi-sensor model-based quality control of mountain forest production
Work Package 4: Multi-sensor model-based
quality control of mountain forest production
The goals of this WP are:• to develop an automated and real-time grading (optimization) system for the forest production, in order to improve log/biomass segregation and to help develop a more efficient supply chain of mountain forest products• to design software solutions for continuous update the pre-harvest inventory procedures in the mountain areas • to provide data to refine stand growth and yield models for long-term silvicultural management

Risks and mitigating actions:
Significant delay related to DoW amandment:• the purchase and delivery of sensors delayed set-up of the system in the lab (laboratory scanner) as well as on the processor head; intensify efforts for all involved partners, direct collaboration and working group meetings, involve additional staff for developments, testing and implementation
Technologies provided will not be appreciated by “conservative” forest users; demonstrate financial (and other) SLOPE advantages
Limited reliability of some sensors when implemented on the forest machinery; careful planning, collaboration with SLOPE (+outside) engineers

Task 4.3 HSI – general setups
• Whiskbroom imaging : During whiskbroom imaging the sample is scanned pixel per pixel in the x–y–spatial direction in a sequential manner.
• Staring (staredown) imaging: Staring imaging is done by a two-dimensional camera capturing the spectral information in each pixel x-, y-plane at once.
• Implementation of the Pushbroom imaging idea: as a line scanning system with multiple sensors acquiring the information for a reduced set of pixels in the line at once – subsequent interpolation planned and possible.

Thank you for your attention!
The objectives of this task is to optimize testing procedures and prediction models for characterization of wood along the harvesting chain, using acoustic measurements (i.e. stress-wave tests).
A part of the activity will be dedicated to the definition of optimal procedures for the characterization of peculiar high-value assortments, typically produced in mountainous sites, such as resonance wood.

Conclusions
Many factors influence SW propagation in wood.
Parameters measured with the other NDT methods will be incorporated in the SW prediction models
Multiple linear regression analysis will be implemented for the definition of the importance of the different parameters (regression t-values) for the model.
The further development of Task 4.4 is based on the implementation of the lab scanner (i.e. purchase of sensors)
For the implementation of the methodology in the real case scenario, some practical issues (e.g. coupling-decoupling of sensors, etc.) have to be considered in combination with activity of Task 3.4
Sensors arrived: work will be done… and is ongoing

CF quality index#2
two quality indexes (numbers in the range from 0 to 1) associated to wood/log properties are determined:
CP quality index #1: reflects the estimation of the “wood density” as related to the cutting resistance during cross-cutting of log by chain saw. The quality index #1 value is unique for the whole log.
CP quality index #1 = f(wood moisture content, tool wear, cutting speed, feed speed, log diameter, ellipsoid shape, presence of defects)
CP quality index #2: reflects the “brancheness” of the log along its length and is estimated by means of signals associated with cutting out branches. The quality index #2 is spatially reolved.
CP quality index #2 = f(hydraulic pressure changes along the log length, changes of cutting forces in time, number of AE events or sound pressure level)

Task 4.6: Implementation of the grading system
Challenges
What sensors set is optimal (provide usable/reliable information)?
How to merge various types of indexes/properties?
Can the novel system be accepted by “conservative” forest (and wood transformation) industry?
How the SLOPE quality grading will be related to established classes?
the final answer possible only after demonstrations
Thank you very much
