Chapter 5 Vision Control

[ 3 ] Major Axis Angle

Image data taken from the camera displays the object as a plane. When the

object on this plane is rotated, the longitudinal direction axis, which is easy to

rotate, is called the major axis of the main axis. The axis vertical to this is

called the minor axis of the main axis.

The µVision board defines an angle () from the horizontal axis (X axis) to the

major axis of the main axis as the main angle. The main axis angle is obtained

to an object in white (1) or black (0), in the designated range of the window

after binarization of the image data.
