Note a maximum exposure duration of 10.0 ms! At a higher exposure, the individual pictures 

may blur when driving too fast and the system may fail to perform the analysis successfully. 

Above an exposure time of 10.0 ms use the LED floodlight. 

 

 

Figure 5: Too low, too high and correct exposure time 

TIP: Even during the day, the use of the built-in floodlight can be helpful. Thus, for example, 

hard contrasts are reduced with only partially sunlit woodpiles. By pressing the button 2.2.1.4 

“Light” you can switch the light on and off again. However, if the light is switched on, it cannot 

be switched off during measurement. You can find more detailed information concerning the 

LED floodlights in Chapter A.5.1.5 

  

Image capture 

 

After adjusting the viewing angle and exposure, drive to the start of the woodpile so that the 

woodpile does not exceed 30% of the camera picture. Begin taking pictures by pressing button 

2.2.1.3 “Start” after you have started to move the vehicle. Drive past the woodpile at a con-
stant, low speed. While taking the pictures, the caption changes on the “Start” button 2.2.1.3 

to “Stop”, the frames around the c

amera pictures flash and below the camera pictures a blue 

progress bar indicates the remaining capacity of the main memory. 

 

When you have passed the woodpile, stop taking pictures by pressing the “Stop” button. The 

message “Postprocessing” appears briefly

 on the monitor.
