Chapter 6 Measurement procedures (LX only)
CAUTION
• The measurement values are not reliable if the above values differ from each other
considerably. In this case, check that the adapter is not loose and the lens components are
not dirty and, if required, execute “Using a new stereo optical adapter (NEW STEREO
ADAPTER)” (page 108) and retry capturing the measurement images.
„ Notes for capturing measurement images
(1) The highlighted part of bright images tend to look textureless. As
matching is difficult with these kinds of images, adjust the
BRIGHTNESS level to darken the image (see “Adjusting the
brightness” (page 62)).
(2) As the illumination comes from one side of the field of view, some
objects produce shadows depending on their shapes. Since
measurement of shadow tends to result in errors, rotate the insertion
tube to remove the shadow before capturing and measuring images.
(3) If the area you want to measure has glare, rotate the insertion tube to
remove the highlight from the area you want to measure and then
capture an image for measuring.
(4) Utilize spot ranging for measuring object distance, capturing the
image close to an object and gaining high measurement accuracy (see
“Spot ranging” (page 124)). Generally the closer object distance is, the
more accurate measurement becomes.
