FH/FZ5 Processing Item Function Reference Manual
Line Regression
Calculates the line that generates the shortest total distance from multiple measurement coordinates (Line
Regression).
It can also calculate the intersection and angle betwee
n two
lines and the distance between a line and a point.
Used in the Following Case
• For computing a line and for calculating the intersection and distance of lines
Function Selection (Line Regression)
Functions are selected depending on application.
1 In the Item Tab area, click [Select function].
2 Select a function in the "Select function"
area.
• Do not set processing units that perform affine transformations such as position compensation between Line Regression
and a unit that inputs for Line Regression.

Description
Select function
• [Calculate line]
Calculates a straight line providing the shortest distance from
mult
iple points (Line Regression).
Set the Line 0 tab.
• Calculate cross point and
an
gle of tw
o lines
Calculates the intersection and angle between 2 Line
Regressions.
Set the Line 0 tab and Line 1 tab. The angle is measured from
L
ine
0 to Line 1 in clockwise order.
• Calculate distance between
li
ne and
point
Calculates the distance between a Line Regression and a
poi
nt.
Set the Line 0 and Point tab.
• Calculate the intersection
and angles of two lines.
• Calculate the distance from the
line to the point
• Approximate multiple measurement
coordinates with a straight line
