With the best state of the art 3D scanners, we can achieve almost every scanning task.
Different scanners have different working principles, but they all measure the distance between itself and a great number of points on the target object in a XYZ coordinate system. All the measurement points have the same reference, so a 3D representation of the object is recreated on the screen just by drawing all the points measured.
Because 3D scanning is a measuring process, the accuracy of the final result is crucial, so the three most important factor to consider are:.
Accuracy: (down to 0.03 mm for single point probing – 0.05mm for 3D scanning)
generally, when people talk about accuracy in 3D measurement what they mean is the accuracy of a single point measurement, which is of course a very important factor. But even if the accuracy of the device is very good, but a low number of point is measured, the representation of the object will be poor.
Resolution: (down to 0.03 mm)
Resolution is the distance between adjacent points that have been measured. The smaller the distance, the better the representation of the object. Imagine representing a human face with points every 20 mm, or every 5 mm, or every 1 mm, or every 0.2 mm. The final result is very different.
Distance: (up to 75 m)
If there is a need to scan the object from afar (if the size is big for example) the accuracy and resolution will drop compare to what is achievable from closer distance.
For a small to medium size object (from few millimeters to a couple of meters) we can provide an accuracy up to 0.03 mm (single point probing) and 0.08 mm in 3Dscanning, with a resolution up to 30 micron. For a larger object the accuracy will be less than a millimeter at 15m distance, with a capabilities to scan object up to 150-200m with resolution from 0.8mm to 5-10mm at longer distance.
