桥式起重机运行环境三维建图偏振光降噪研究

Research on polarized light noise reduction for 3D mapping of t he operating environment of bridge crane

在桥式起重机运行环境双目视觉三维建图任务中,为减少因反光耀斑所造成的建图误差,文中对双目相机采集的图像使用偏振滤镜对偏振光进行过滤,使用搭建的实验台进行了实验,比较了偏振滤镜对三维地图精度的影响。结果表明:偏振滤镜可以有效过滤物体表面反光,减小建图误差,提高建图结果的鲁棒性。

In the three-dimensional mapping of binocular camera in the operating environment of bridge crane,in order to reduce the error caused by reflective flare,polarized filter is used to filter the images collected by binocular camera,and experiments are carried out on the experimental platform,and the influence of polarized filter on the accuracy of three-dimensional map is compared.Results show that the polarized filter can effectively filter the reflection of the object surface,reduce the mapping error and improve the robustness of results.
