检测木板上的荧光标记 木板上有缺陷的地方已使用荧光标记出来。荧光标记的宽度通常在15mm左右,有时两条标记的间距仅有20mm,传感器需要能够分别识别这两条标记。传感器需在距离被测物200mm处进行检测,且要能够识别宽度仅有5mm的标记。
Color detection of fluorescent marks on wood plates
On wooden plates defects will be marked with a fluorescent marker. The fluorescent mark has normally a width of about 15mm and it can happen, that two of this marks lie 20 mm away of each other, but must be detected as two separate marks. Furthermore the fluorescent marks should be detected at a distance of 200 mm to the object and even a mark with a width of 5mm should be detected.
