5.10.6.2 Smart 3D Acquisition Preparation
In Smart 3D mode, you need to set the scan method in addition to the other items in
Static 3D mode. The other parameters are the same as those for Static 3D. For details,
see "5.10.3.2 Static 3D Acquisition Preparation."
Method
Capture images using Linear scan or Rocked scan.
Linear scanning
Move the probe across the surface. See the following figure.
Rocked scanning
Rotate the probe once from the left to the right side (or from the right to the left)
to include the entire desired region. See the figure.
Description of parameters:
Parameter
Function: select the image acquisition method.
Selection: Rocked, Linear.
Linear mode: during the sweep, the probe must be kept parallel. The
scanning speed should be constant.
Rocked mode: in this mode, the probe must be moved to a position where
Method
you can clearly see a middle cut of the object you want to scan and render.
Tilt the probe to about 30 degrees until the object you want to scan
disappears. Start the acquisition and tilt the probe over a distance of around
60 degrees until the object disappears again. During the sweep, the probe
may not be moved parallel, just tilted.
Tip: the speed is related to scanning distance or angle.
Function: to set the distance the probe covered from one end to the other
end during a linear sweep.
Distance
Range: 10-200 mm, in increments of 10 mm.
Function: to set the angle the probe covered during a fan sweep.
Angle
Range: 10-80°, in increments of 2°.
