Marker-Based Target Location and Recognition for Visual Robot

Abstract

To solve geometric object crawling issues for visual robot,here we try to place series of specially designed markers in the geometric center of the surface, and store the relevant information of the corresponding object to the identified ID,so that the object crawling issue has become the the location and identification of markers ID.In this paper the author designs a marker system on Hamming code, detects the identity quadrilateral by counterclockwising finishing contour point and calculating the the contour perimeter in the image processing procedure,and then identifies the ID with the the decoding theory. Simultaneously Harris algorithms are chosen to extract the four corner coordinates of the sub-pixel accuracy. Experiment and theory show that the method can achieve the object location and recognition .
