本文主要研究了利用GPS摄像机和立体摄像机进行桥梁养护周期性数据采集的方法。首先，我们选择了一些元素来拍摄相同的照片。此外，我们还在这些元素下拍摄了照片，并对这些照片进行了评估。从实验结果中，我们已经证实，我们可以从相同的位置使用GPS相机在以前的检查拍照。其次，我们已经能够获得与近距离目视检查相对应的3D数据。因此，我们验证了是否可以准确地提取裂纹的三维测量在远处的位置。因此，我们定义了条件约束，在立体测量，以获得准确的三维数据在定期的数据采集。最后，我们已经提到，我们提出的方法可以评估桥梁结构退化的过程中使用的照片。
In this paper, we focus on the periodical data acquisition using GPS camera and stereo camera for bridge maintenance. Firstly, we took up some elements to take same photos. Additionally, we took photos under those elements and evaluated those photos. From experimental results, we have confirmed that we can take photos from same positions using GPS camera at the previous inspections. Secondary, we had already been able to acquire 3D data corresponding to close visual inspection. Therefore, we verified whether can accurately extract the cracks in 3D measurement at far position. As a results, we have defined condition constrains in a stereo measurement to acquire an accurate 3D data in periodical data acquisition. Finally, we have mentioned that our proposed methodology can evaluate a progress of bridge structure deterioration using photos.
