车载激光点云道路边界提取的Snake方法
车载激光点云 主动轮廓模型(Snake) 道路提取 梯度 能量函数
font style='font-size:12px;'>
2021/6/2
针对车载激光点云中道路边界提取困难,自动化程度低的问题,提出一种基于离散点Snake的车载激光点云道路边界提取方法。不同于传统基于图像建立Snake,本文直接基于离散点建立Snake模型。先利用伪轨迹点数据,确定初始轮廓位置,参数化不同类型的道路边界初始轮廓;然后基于离散点构建适合多类型道路边界的Snake模型,定义模型内部、外部和约束能量,通过能量函数最小化推动轮廓曲线移动到显著道路边界特征点处...

SfM摄影测量方法在活动构造定量研究中的应用
摄影测量 Structure from Motion(SfM) 高精度地形地貌数据 活动构造
font style='font-size:12px;'>
2018/5/17
高精度、高分辨率的地形地貌数据是活动构造定量研究的基础。摄影测量方法的出现和快速发展为获取高精度地形地貌数据提供了一种经济有效的技术手段。相比于传统的测量方法,摄影测量方法可在大范围内同时进行,不受地面通视条件的限制,且测量成本相对较低。尤其近年来,随着计算机视觉理论及高效的自动特征匹配算法的发展,一种名为"Structure from Motion"(SfM)的三维重建技术被引入摄影测量方法中,...
