This
paper talks about the vision systems that allow the receipt of information on
relative object motion in real time. It is shown, that the algorithms solving a
wide range of practical problems by definition of relative movement can be
generated on the basis of the known algorithms of an optical flow calculation.
Works in the field of an optical flow calculation have been conducted for more
than 30 years. Last decade these methods were used in a wide range of applied
problems due to increase of computers computing capacity and the occurrence of
specialized graphic processors. There are many articles that have been written
on the subject of optical flow methods. There are also widely available
libraries with an open code, in which the ready applications of the most
popular optical flow methods could be found (for example, OpenCV, LTI-Lib, VXL). Methods of an
optical flow appear to be useful for segmentation of images, and also for
detection of obstacles from moving objects.
