摘要: 針對地震后高層建筑物結(jié)構(gòu)損傷監(jiān)測問題,該文提出一種基于方向碼匹配(OCM)和邊緣增強(qiáng)匹配(EEM)算法的微小位移測量算法。該算法先將原始圖像梯度信息與像素強(qiáng)度融合,增強(qiáng)圖像信息;采用相位相關(guān)法進(jìn)行匹配運(yùn)算,匹配速度比歸一化互相關(guān)法提升了96.1%;最后使用亞像素插值法,使測量結(jié)果達(dá)到亞像素精度。實驗結(jié)果表明,該文算法避免了OCM和EEM算法量化過程中圖像梯度信息的損失,大大提高了模板匹配精度,匹配速度比OCM提升了43.3%,比EEM提升了19.6%。Abstract: A micro-displacement measurement algorithm is proposed based on the Orientation Code Matching (OCM) and Edge Enhanced Matching (EEM) algorithms for monitoring the structural damage of tall buildings after earthquake. The algorithm first fuses the gradient information of the original image with the pixel intensity to enhance the image information; Then the phase correlation method is used to perform the matching operation, the matching speed is 96.1% higher than the normalized cross-correlation method; Finally, the sub-pixel interpolation method is used to make the measurement achieve sub-pixel accuracy. Experimental results show that the proposed algorithm avoids the loss of image gradient information during the quantization of OCM and EEM algorithms, greatly improves the template matching accuracy, and the matching speed is 43.3% higher than OCM and 19.6% higher than EEM.
