关于点云赋色 #36
Comments
您好,感谢你的问题。fast-livo2的点云上色策略与fast-livo1保持一致,即直接将每帧的原始点 (raw points) 通过优化后的位姿投影到对应图像上进行赋色,然后发布到rviz中进行可视化。相比于后处理的多帧点云上色或使用贝叶斯更新来平滑地图颜色,这种方式能够更加直观地暴露位姿估计的问题。只要pose存在细微的误差,彩色点云就会出现模糊,从而更快定位问题。 |
了解,谢谢您的解答! |
请问,“后处理的多帧点云上色或使用贝叶斯更新来平滑地图颜色”分别具体是指什么样的方法,有哪些论文或开源工程使用了这样的方法吗? |

好的,感谢解答! |
郑博,
你好,我想请问一下点云赋色是怎么做的,在Fast-livo里面好像优化位姿后直接使用点云往图像上投影得到RGB,Fast-livo2最后点云赋色有使用patch的信息或者voxelmap里的点信息吗?
