Abstract:

A machine vision technology is used to detect the ground feature, based on block matching algorithm for AGV navigation. First, the overlap of each two frame images is
identified. Second, the overlap of two images of different frames is found by using feature block matching algorithm. Last, through calculating the overlap image in the previous
frame offset, the distance of the car moving is calculated. So far, the calculation of the cars track is completed. Experiment results show that prototype system of this
method reached the anticipated result under different conditions of ground, and the method is proved to be effective.

Key words: AGV (Automated Guided Vehicle), machine vision, image processing, block matching, indoor navigation
