AI Technical Summary
Technical Problem
Existing technologies for improving the resolution of detection point clouds have drawbacks, such as increased material costs or uneven resolution within the field of view.
Method used
Point cloud data is obtained by misaligned scanning and then superimposed according to the misaligned positions, including inter-line misaligned scanning and inter-frame misaligned scanning, to ensure that the scanning positions are staggered under orthogonal relationship and achieve uniform superposition of point cloud data.
Benefits of technology
Without increasing the material cost of the detection equipment, a uniform improvement in point cloud pixel resolution was achieved, thereby improving the detection accuracy of obstacle edges.

Abstract
本申请提供的点云分辨率增强方法及相关装置中，探测设备通过错位扫描的方式获得点云数据；将点云数据按照错位后的位置进行叠加，获得分辨率增强后的目标点云；由于每错位扫描一次的点云数据，其扫描位置相较于上一次扫描时的扫描位置整体进行了平移，从而使得点云数据不再呈现对齐的扫描效果，因此，叠加之后的目标点云能够在不增加探测设备物料成本的情况下，更为均匀的提升点云像素的分辨率。
