Abstract

When an object moves relative to a sensor, the motion of its image in the image plan produces an image flow field. The calculation of image flow which involves obtaining a velocity vector at each pixel is considered very important in the area of robot vision. This paper introduces a method for the calculation of optical flow generated by the motion of planar objects under orthographic projection. The proposed method consists of two phases. In the first phase an interpolation technique is introduced to obtain the correspondence of dense feature points. In the second phase a least squares method is used to estimate the optical flow parameters from the corresponding point pairs obtained in the first phase.
