一种机载LiDAR点云条带重叠度自动检查算法

Automatic Detection Algorithm for Stripe Overlap Based on Airborne LiDAR Data

为提高旁向重叠度检查效率,提出了一种基于点云边界数据的全自动条带旁向重叠度快速检查方法。该方法根据微积分原理对条带重叠区进行带状采样,并自动计算每个采样位置的旁向重叠度。实验表明,该方法快速有效,能极大程度地提高重叠度检查效率,有很强的实用价值。

In order to improve the efficiency of side-overlap checking,we present a fast side-overlap automatic detection method based on point cloud boundary data.According to the principle of calculus,the stripe overlap region was sampled and the side-overlap of each sampling position was calculated automatically.The experimental results show that the method is fast and effective,which can greatly improve the efficiency of overlap inspection,and has a strong practical value.
