Projection Distance - Panasonic MICRO-IMAGECHECKER AX40 User Manual

7.2.7 Projection Distance

Projection Distance is a function to quote the coordinate value of the checker that the axis is rotated only
by the adjustment angle. If the feature is used for the object having a slope, the object can be measured
without using a trigonometric function including arctangent.
Checkers to detect the positions
Checkers to detect the positions of the objects. See "List of Quotable Data to Numeric calculations" on
page 144.
Example of use
The length L of the following object having a slope is calculated by creating a group binary edge checker
and a rotation adjustment edge checker and quoting the detected X coordinate.
Length L can be calculated with the trigonometrical function or only by subtracting the X/Y projection
distances (Length L = X projection distance of Binary Edge 2 - X projection distance of Binary Edge 1).
When not using projection distance.
This feature is available only if the number of the checker that can detect the position of the object
and that is assigned to Rotation Adjustment is specified.
