Detecting Rotated Object
If a detecting part is rotated or capturing direction is possible to be unstable, it is
necessary to scan within a search area rotating the image pattern registered as a
template. To do so, set a rotation angle and angle pitch.
1.
Select "Inspection Condition".
2.
Specify the value of "Rotation Range" from 0 (no rotation) to +/-180 (rotation of 360-degree).
Note that the larger value of rotation angle range you set, the longer time its processing takes.
3.
Specify "Angle - Step".
At first, set a pitch to scan. Select from 8, 4, 2, and 1. Selecting "8" scans Rotation Range by 8 degrees and
finely scans around the detected angle.
When setting "Recommendation Setting" from "Sequence", "Angle - Step" will be automatically replaced to
the Recommendation Setting.
4.
Specify "Angle - Accuracy".
This item is to set an angle to scan finely around a detected angle.
Select either "1 Degree" or "0.001 Degree". The detected angle is output lastly in the unit set here.
Setting "0.001 Degree" takes longer process time than "1 Degree."
5.
After setting is completed, press the CANCEL key.
