Abstract

With the continuous improvement on the refined management of coal-fired power plant, it is a necessary task to accurately obtain the total quantity of coal in power plant. In this paper, ORB (Oriented Fast and Rotated Brief) - edge coupling method was proposed for the coal pile to strengthen the weak texture boundary of coal pile images, and thus improve the feature extraction and matching capacity. The results showed that our proposed algorithm can increase the number of feature points by a factor of about 10 times relatively to the ORB algorithm. Furthermore, three types of coal piles were examined to evaluate the number of feature points. The results showed that the accuracy rate of feature point matching can reach up to 90%, indicating that our proposed algorithm has the good effectiveness and applicability.
