摘 要: | 三维激光扫描点云带来了大量客观世界信息,但在数据处理及可视化方面也给研究人员带来了新的挑战,单纯的三维明暗处理技术产生的点云图像并不具备可量测属性。为了获得真实的立体感,点云的可视化可以通过透视投影变换和OpenGL技术产生左右两幅点云图像,通过双目立体观测的方法去重现点云实体世界。本文分析并验证了双目立体观测点云精度。

Abstract: | Three-dimensional laser scanning cloud points not only brought a lot of object information, but also brought new challenges to researchers in data processing and visualization. The shading cloud points image does not have measurable properties. In order to obtain true three-dimensional cloud points visualization, it's suggest to produce two cloud points images by perspective projection and OpenGL technology. This paper analyzes and verifies the accuracy of cloud points in binocular observation. |
