1. Work Package 4:
Multi-sensor model-based quality
control of mountain forest production
by CNR: Jakub Sandak
3rd SLOPE project, 19 January 2015, San Michele All’Adige
2. 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 changes in the consortium:
•lack of the practical expertise of the processor head engineers;
technical meetings, new partners/collaborators
•the selection, purchase, set-up of the new processor hear is
delayed; development of the laboratory scanner capable to
simulate log scanning
Technologies provided will not be appreciated by “conservative”
forest users; demonstrate financial (and other) SLOPE advantages
Difficulties with integration of some sensors with forest machinery;
careful planning, collaboration with SLOPE (+outside) engineers

•All sensors are expected to work during first demo?
How to deal with the overall delay?
•Need to update Gantt(s) ?
How to deal with the new DoW?
•Need to update list of activities ?
The communication between partners is not optimal… how to

28. T4.1 Overview
Task 4.1 - Data mining and model integration of
stand quality indicators from on-field survey for
the determination of the tree “3D quality index”.
The Task 4.1 aims at evaluating the effectiveness/reliability, as quality
indicators, of single and combined parameters related to the external
characteristics of the standing tree, such as tree height, diameter, stem
taper, straightness, sweep and lean, branchiness, branch length, thickness
and dimension of the live crown

31. TLS Analysis
Step 2: Local DTM generation
Autostem software generates a best fit plane for the local DTM based on point cloud data.
Once Local DTM is established, tree profiles are defined relative to this.
Step 3: Single tree detection:
Autostem, Profile disks are fitted around cylinders in the point cloud data at every 10cm.
If insufficient points in the cloud a specific height, a disk is interpolated between nearest
disks above and below.
Upper section of tree is calculated using local taper equations.
Technical Meeting
19-21 Jan 15
34. TLS Analysis
Stemfiles are generated that fully support the Standard for "Forestry Data and
Communication" (StanForD) standard in a widely accepted file with ".stm" extension. The
allows for storing of x,y,z and diameter for each decimetre disk on the stem.
**This format does not allow for extra stem quality information to be stored. **
The extra information should either be stored in a linked file to the .stm file or a new
approach that does not support the StanForD standard can be used.

42. Conclusions
The main conclusions about the stand quality indicators and harvest simulation are the
following:
• The MAIN indicators to define the log can be easily measured using the stem 3D model
created using TLS data.
• Additional quality indicators can be measured and applied to the log constraints.
• Internal quality of the timber can be estimated by using quality models. These models
will be applied to the 3D stem profile and used in the harvest simulation. This will be
described in deliverable D4.07

NIR quality index #1 will be related directly to the health status, stress status and to the
productivity capabilities of the tree(s) foreseen for harvest
Tree marking
Direct measurement of the NIR spectra by means of portable instruments (DA and LVF) will
be performed in parallel to the tree marking operation. The spectra will be collected and
stored for further analysis (NIR quality index #2)
Cutting of tree
testing the possibility of collecting sample of wood in a form of the triangular slice being a
part of the chock cut-out from the bottom of the log (NIR quality index #3)
Processor head
NIR sensors will be integrated with the processor head (NIR quality index #4). All the
sensors will be positioned on a lifting/lowering bar on the head processor near the cutting
bar. The cutting bar will be activated in two modes: automatic and manual

56. Detailed procedure related to measurement of NIR along
the whole harvesting scenario
Pile of logs
The cross section of logs stored in piles is easily accessible for direct measurement. Such
measurements will be repeated periodically in order to monitor the quality depreciation
and to determine the most optimal scanning frequency. The result of measuring NIR
spectra of logs stored in piles will be NIR quality index #5
Laboratory
Samples collected in the forest will be measured instantaneously after arrival in the
laboratory (at the wet state and with rough surface) by using the bench equipment
(NIR quality index #6). However, samples will be conditioned afterward and their surfaces
prepared (smoothed) in order to eliminate/minimize effects of the moisture variations and
light scatter due to excessive roughness on the evaluation results of fresh samples.

hyperspectral imaging
Project meeting
19-22/jan/2015
Spectra at on one spot Spectra at each pixel
• Ranges within the electromagentic spectrum
• Visible wavelength range ~ 390-700 nm
• NIR wavelength range ~ 780 nm and 3 μm
Advantages:
• remote sensing
• segmentation of object
• scanning non-homogeneous surface
Disadvantages:
• non-izolated (lower signal to noise ratio)
• setup dependant calibration (distance, lens, illumination)
• indefinite geometry (illumination/observation angle)
• huge amount of data must be processed
Specific software needed (control system, calibration, data
processing)

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

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?
Some same as in before, but the final answer possible only after demonstrations

133. Task 4.1: 3D quality index
Objective: the use of laser scanners for 3D mapping of standing
trees and experiences of Treemetrics in 3D data evaluation
on order to determine 3D quality index on standing trees
Method: detailed methodology for the hardware set-up and
measurement procedure has been described in Deliverable 4.2.
Algorithm: The custom software developed at TreeMetrics will
be used for visualization of the tree shape and for computation
of the stem dimensions (including diameters, taper, tree height).
The quality index will include the estimated quality class,
recommended cross-cut pattern and suggested market for each
measured log.
Technical Meeting

134. Task 4.2: NIR quality index
Objective: the use of NIR for determination of selected wood
properties, detection of some wood defects and determination
of the NIR quality index on both standing trees and logs.
Method: NIR technique will be used for measuring spectra at
varying stages of the harvesting chain: tree marking, tree feeling,
processing on the processor and storing in the stack. NIR sensor
will be integrated with the processor head in order to allow in-line
acquisition of spectra and determination of the log quality
Algorithm: two approaches will be tested: laboratory and in field

logs and wooden samples extracted from trees/logs.
Method: HI will be used for measuring spectral hypercubes at
varying stages of the harvesting chain: tree marking, tree feeling,
processing on the processor and storing in the stack. HI sensor will
be also integrated with the processor head
Algorithm: two approaches will be tested: laboratory and in field

136. Task 4.4: stress wave quality index
Objective: the use of SW propagation parameters for pre-grading
logs in forest on the base of correlated mechanical and physical
properties of the wood material (dynamic modulus of elasticity,
density) and the presence of damage, decay or other defects
Method: SW measurements will be carried out at various stages
of the harvesting chain: on the standing tree, felled tree and
debranched logs. Additional measurements in lab, to calibrate
measurements and determine correlation with selected material
properties and standard commercial classes.
Algorithm: two approaches will be tested: laboratory and in field

137. Task 4.5: cutting forces quality index
Objective: to develop on line system for determination of selected
wood properties and technical characteristics by measurement of
cutting forces associated with processing of logs in forest
Method: Two strategies will be tested:
•Cutting resistance of the chain saw cross-cutting the log
(The hydraulic pressure and oil flow will be measured. It will be later regressed
against wood density and cross-section geometry)
•Resistance of the de-barking knives as measured during the stroke
(The hydraulic pressure, mechanical deformations of the knife holder, acoustic
emission associated with the cutting out branches will be monitored. The presence,
number of branches and its health will be detected as a result)
Algorithm: 2 set of info will be extracted: wood density and branch idx
