An X-ray based experimental study is presented for determining the overlaps
and horizontal density distribution (HDD) in a robot formed wood flakeboar
d mat. The relationship between overlaps and the X-ray intensity ratio has
been developed. The results show that the calibration materials have little
effect on the overlaps obtained from X-ray scanning and the estimated over
laps highly agree with those from computer simulations. Robot formed flakeb
oard mats have higher repeatability with lower deviation in both overlaps d
istribution and HDD.
