7.2.7 Projection Distance
The Projection Distance function is used for quoting the coordinate values of the axes rotated only by the
adjustment angle when then checkers capable of detecting the object positions is created. If the feature is used
for the slanted object, the object can be measured without using a trigonometric function in which arctangent is
used.
Checkers capable of detecting a projection distance
All of the checker capable of detecting the object positions can detect projection distance. See "A List of Data
Can Be Referred to Numeric Calculation" on page 169.
Example of use
The length L of a slanted object shown below is calculated by creating a grouped binary edge checker and a
Rotation Adjustment Edge checker and by quoting the detected X coordinate.
The Length L of the object can be calculated using the trigonometrical function, but if you use X/Y projection
distances, the Length L is easily calculated only by following the formula below.
(Length L = X projection distance detected by a Binary Edge checker saved as checker No. 2 - X projection
distance detected by a Binary Edge checker saved as checker No. 1).
When using projection distance
The Projection Distance function is available only when specifying the number of the checkers that detect an
object position and set Rotation Adjustment checker in the "Position Adjustment" settings.
