Abstract: Feature-based visual servo control methods determine camera motion
by comparing a current feature image and the goal feature image. Because these
methods do not require 3D information for the object, no geometric model of the
object is needed, and it is therefore robust against various disturbances. Several
feature-based visual servo control methods have been proposed, such as using a
wide-angle lens allows the camera to capture the object in a wide angular range.
However, when using a wide-angle lens with a conventional control scheme the
camera undergoes wasted motion due to the peripheral distortion of wide-angle
lenses. In addition, correction of the image distortion results in the loss of the
wide-angle properties of the lens. This paper proposes a new feature-based visual
servo control method based on a super wide-angle lens that preserves wide-angle
properties.
Keywords: visual servo; wide-angle lens; lens distortion; space robotic
manipulator control.
