摘要
对于悬索桥,斜拉桥和拱桥来说,索或拱轴线的线形对整个桥梁的运营至关重要.通过室内实验对拉索进行模拟研究,采用基于图像处理技术对拍摄获得的图像进行图像转换、图像增强以及边缘检测处理,从而拉索的边缘图像坐标,再根据人工标志获取的图像转换系数实现线形识别的目的.通过多组对比实验,获得了正确的拍摄方法,运用该方法可以得到很高的线形识别的精度.
For the suspension bridge, cable-stayed bridge and arch bridge, the cable or cable axis of the entire line of the operation of the bridge is essential. Through the simulation of the cable of the indoor experiment, this paper uses image processing technology to obtain the image conversion, image enhancement and edge detection to get the edge coordinates of cables for the image of the captured image. According to the image conversion coefficient obtained by manual marking, the purpose of line recognition is achieved. In this paper, the correct shooting method is obtained by multi group contrast experiment, and the accuracy of line recognition can be obtained by this method.
