摘要
为实现局部病害图像在桥梁三维运维模型中的实时自动精准定位,提出基于无人机巡检图像、GPS坐标和BIM模型的桥梁病害自动化定位方法。首先提出通过坐标投影与映射方法将病害图像坐标由GPS WGS-84坐标系映射至BIM模型坐标系;然后建立基于BIM模型的坐标配准算法,将2D病害图像配准于所处的BIM模型实体单元,实现病害图像与BIM模型的联动;最后基于Autodesk Revit环境开展二次开发,实现算法落地。采用无人机进行了桥梁病害采集与现场试验,验证该方法的精度和可行性。结果表明:基于无人机拍摄的图像及所包含GPS信息,采用本方法可实现桥梁病害在BIM模型上的实时自动化精准定位,整体定位绝对误差平均值为19.50 cm,构件定位准确率为98.8%,基本满足桥梁巡检要求;该研究成果具有较高的可行性和工程应用潜力,可以为桥梁长期运维管养提供精准数据与决策支持。
In order to realize the automatic real-time and accurate localization of local defect images in the 3D operation and maintenance model of bridges,a bridge defect automated localization method based on unmanned air vehicle(UAV)inspection images,global positioning system(GPS)coordinates and BIM models was proposed.Firstly,a coordinate projection and mapping method was proposed to map the defect image coordinates from GPS WGS-84 coordinate system to BIM model coordinate system.Then,a coordinate registration algorithm based on the BIM model was established to register and align the 2D defect image to the component unit of BIM model,and realized the linkage between the defect image and the BIM model.Finally,the algorithm was implemented by secondary development based on Autodesk Revit environment.The UAV was used to conduct the bridge defect acquisition and field test,and the accuracy and feasibility of the method were verified.The results show that based on the images taken by UAV and the contained GPS information,the proposed method can realize real-time automated accurate localization of bridge defects on BIM model.The overall localization mean absolute error is 19.50 cm,and the component localization accuracy rate is 98.8%,which basically meets the requirements of the bridge inspection.This research has enough feasibility and engineering application potential,and can provide accurate data basis and decision support for the long-term inspection and maintenance of bridges.
