Paper Abstract

A new approach was proposed for detecting and segmenting the beacons from low contrast infrared image captured from two CCD detectors fixed on two sides of deck, respectively. Adaptive thresholding is used for obtaining binary image of the infrared beacons by rough segmentation in preprocessing step, which probably contains some non-beacons areas. Then line encoding is conducted for binary image containing beacons and non-beacons, which is a look-up table (LUT) with little data quantity. Refined beacons extraction and recognition based on various features are conducted within LUT data. Finally, the geometric features (e.g. rectangularity, circularity, eccentricity) combining with the moment invariants is used to recognize the real beacons by minimum euclidean distance and prior information of artificial beacon. Experimental results show that the proposed method can preserve the perfect shape of beacons and effectively detect and track it for opto-electronic guiding system.
