3. Measurement
 Only woodpiles that comply with the woodpile requirements in Chapter B.2 may be
measured!
 The user must have received a detailed briefing on the measurement system and
knowledge of this Operating Instructions!
 The weather conditions must allow a measurement with sScale™ (see Chapter B.1 and
B.3).
3.1. General procedure
You need to drive past the woodpile at a distance, which ensures that the entire woodpile
height is visible in the monitor. Experience has shown that this is generally so when the dis-
tance corresponds approximately to the height of the woodpile. The minimum distance is 1.9
m.
After analysing the pictures, the polygonal course must be adapted to the outer contour of the
woodpile face area and further administrative data entered.
The measurement results are then stored in the system and transferred to the separate
sScale™ server. After the transfer, changes to the measurement cannot be made to the
sScale™ system in the forest nor the sScale™ server!
NOTE:
Use a digitiser pen with a thin plastic tip for all work on the monitor. Using, for example, metal-
tip pens results in damage to the monitor and significant costs to the customer if a monitor
needs to be replaced.
3.2. Measurement step by step
3.2.1. Image capture
Preparations
Start the system with the on / off button on the back of the screen and wait until an image is
visible in both camera windows and a GPS position is displayed. Drive to the highest point of
the woodpile to align the cameras with buttons 2.2.1.5 “Arrow” so that both the top and
bottom edges of the woodpile are visible in the camera images. If necessary, increase the
distance from the woodpile face area (see Figure 4).
Figure 4: Too low, too high and correct camera alignment
Set the correct exposure at the same position (see Figure 5). If the woodpile is in both bright
sunlight and dark shadows, adjust the exposure at the transition point to best cover both
exposure situations.
