船舶引航梯安全检测方法

Safety Detection Method for Pilotage Ladder

针对船舶引航梯的安全检测问题,提出基于Adaboost及Haar特征的引航梯安全检测方法,以某船引航梯检测为例,构建引航梯的图像特征,借助Haar特征的抗光照、旋转等性质,提取引航梯缝隙特征,选择Adaboost方法对提取到Haar特征进行训练及融合,并引入积分图加快检测速度。结果表明,检验结果与实际结果吻合较好,可实现船舶引航梯中微小裂缝的检测和识别。

With respect to safety detection issues for pilotage ladder,a safety detection method for pilotage ladder based on Adaboost and Haar features was proposed. Taking the pilotage ladder of a ship for example,the image features of the pilotage ladder was constructed,the anti-illumination and rotation properties of Haar feature was applied to extract cracks characteristics of the pilotage ladder. The Adaboost method was used to train and fuse the extracted Haar features,and the integral diagram was introduced to improve the detection speed. The results showed that the detective results are in good agreement with the actual results,so as to detect and identify the tiny cracks of pilotage ladder of ships.
