Research on Artificial Landmark Recognition Method Based on Omni-Vision Sensor

To realize location and navigation, the robot need exactly know the position of artificial landmark in environment. In this paper a kind of artificial landmark recognition method based on omni-vision sensor is proposed. This method has three steps: color feature extraction, region segmentation and feature screening. And this method has the characteristic of simple arithmetic and well real-time quality and it is proved to be effective by experiment.
