•
– Set up a grid-based calibration to correct camera
lens and tangential distortion: print the grid target, convert the image
to grayscale, and evaluate the performance of the available distortion
models.
•
Correct a Grid-Calibrated Image
– Apply a geometric correction to an
image based on a previous grid-calibration step.
•
– Set the coordinate system relative to a standard
feature of an object, e.g., a corner defined by two edges.
Machine Vision
•
Find the Intersection of Two Lines
– Use the “Caliper” to find the
coordinates of the intersection of two straight lines found in previous
steps.
•
Measure the Distance Between Two Points
– Use the “Caliper” to mea-
sure the distance between two points.
•
Measure a Perpendicular Projection Distance
– Use the “Caliper” to
measure the perpendicular projection distance between a baseline defined
by two points and a third point.
•
Find Midpoint Between Two Points
– Use the “Caliper” to find the
midpoint between two points.
•
Measure the Angle Formed By Two Lines
– Use the “Caliper” to measure
the angle between two lines defined by four points.
•
– Use the “Caliper” to make multiple
measurements in a single step.
•
– Connect the “Gauging Demo” Vision
Assistant script to the Express VI in LabVIEW.
