The Boards expectations to NVM


Grading and scaling function:


Priority on reducing costs within the main core activity


Adequate settlement basis



Other tasks:


Must be developed further, has to support rational scaling.


New service offer:


Must create value for the business chain

Boards expectations to NVM


Control results:


Goal: 0

outcome


Methods should be evaluated


Increased automation


changing conditions


Development projects saw logs


Single log test sampling procedure


Objective measurable criteria


automatically registered


Development projects pulpwood:


Photo and web technology


NVM should be engaged in development and not research

installed in Opsund:

-
The laser is set up in connection to a normal measuring
platform.

The laser

-

By means of 2 cameras the position and speed of the lorry
are calculated.

-

Traffic light in the front and back edge.

Camera house for outdoor use with
heating element.

11

State of affairs and further work



Modus 2000




Good measuring results regarding repeatability


The systematic deviation of the volume is to big.


Further testing of the laser equipment with the aim
of using the values form the laser as the ordinary
settlement of the measuring act.

12

Photo

web technology


The method is a variation of our ordinary SWVM
-
grading
and scaling system



The various dimensions is measured directly on the pictures



Correct calibrating of the cameras is a presuppose for
correct measuring



Independent of where and when the grader is working

13

The measuring platform

Office

Red circle = camera;


3 cameras alongside the
lorry and trailer to
registrate the volume of
each stack.

3 cameras to survey
each end face of each
stack.

Yellow circle = possible
additional cameras;


1 camera to identify the
lorry.

1 camera to survey the
top and the other side of
the vehicle.

Idea of organising the cameras
-

(Braskereidfoss)
:

14

A standard monitoring camera
has been tested in stage 1.
Upgraded in stage 2 with a
camera with 5 mega pixels

The equipment is set up
on moveable poles


giving full flexibility in
the testing period.

15

The pictures are presented in a standardised set
-
up on

the
PC
-
screen.

16

The electronic ruler can be used in various positions on the screen:

17

The grader can zoom within the
pictures to study various details
closer.

18

The quality of the pictures
will be further improved after
calibration and fine
-
tuning of
the equipment.Coming
generations of equipment will
improve the possibilities
further.

The good zooming possibilities gives a good
overview and a great flexibility for the grader:

The data from the Photo

-
project


77 stacks pulpwood of spruce



55 stacks of pulpwood of pine



41 stacks of saw timber spruce



10 graders have done the interpretation of the
pictures



Data from two measuring sites in Norway


The tests have been done in spring


summer 2008

Further work with the Photo
-
web


Further testing of the grading specially for the winter.


Building knowledge


training of a number of graders in
Photo
-
web.


Plan and specify a technical requirement for an ideal
measurement site equipped with Photo
-
web.


Describe procedure of grading through Photo
-
web
including routines for control.


Clarify investments in cooperation with our owners.


Ambitions


common grading through Photo
-
web in 2010
.

Summary of the Photo
-
web



NVM think the Photo
-
web will give:



-

Efficient grading


-

An improved use of our grading capacity



-

A safer data
-

registration



-

A safer documentation


The pictures can be filed


-

24 hours open measurement site for the lorries without
graders on the spot all the time.




NVM believes that the SWVM
-
method can through Photo
-
web
be done independent of where and when the grader is working.
