岩石剥离事件沿着道路造成公共安全问题，但可以预测和安全地处理使用地质测量的不连续性。借助现代传感技术，这些测量可以在三维点云和二维光学图像上进行，从而提供高水平的结构精度和视觉细节。这样做使工程师能够相对轻松地获得所需的数据，同时消除手动测量中固有的偏差和危险。这封信提出了一种融合自然和非结构化场景中的2-D和3-D数据的方法。这包括一种新的方法，用于可视化使用非常不同的传感器获得的图像，以最大限度地提高它们的视觉相似性，使注册成为一项更切实的任务。为了显示我们的注册方法的有效性，我们评估手动和数字化测量岩石刻面和切割不连续性的方向在罗拉，密苏里州。我们的方法是能够对齐的2-D和3-D数据的精度在2厘米。由地质工程师手动获得的测量值与使用我们提出的软件获得的测量值之间的中值差为3.65。
Rock detachment events along roadways pose public safety concerns but can be predicted and safely handled using geological measurements of discontinuities. With modern sensing technology, these measurements can be taken on 3-D point clouds and 2-D optical images that provide a high level of structural accuracy and visual detail. Doing so allows engineers to obtain the needed data with relative ease while eliminating the biases and hazards inherent in taking manual measurements. This letter presents an approach for fusing the 2-D and 3-D data in natural and unstructured scenes. This includes a novel method for visualizing imagery obtained with very different sensors to maximize their visual similarity making registration a more tangible task. To show the effectiveness of our registration methodology, we evaluate measurements taken manually and digitally on rock facet and cut discontinuity orientations in Rolla, MO. Our method is able to align the 2-D and 3-D data with an accuracy of under 2 cm. The median difference between measurements manually obtained by a geological engineer and those obtained with our proposed software is 3.65.
