  • orb-slam在众多SLAM方法中处于怎样的地位? - 知乎
    特点是以orb特征贯穿始终,从一开始的特征处理,匹配,以及用于回环的bag-of-words,词典,全用的是orb。 下面说说我个人对它的一些看法。 作者从opencv2 4的orb改进了一版,比opencv里的orb多了一个网格处理,尽量保证每小块图像都能提到特征,避免了局部特征点
  • 视觉SLAM开源算法ORB-SLAM3 原理与代码解析 - 知乎
    ORB-SLAM1只能针对单目相机数据进行处理;ORB-SLAM 2 增加了对于双目和RGB-D相机的处理,在回环检测模块增加了Full Global BA的处理;ORB-SLAM 3则增加了对于IMU融合的支持,兼容鱼眼相机模型,并且增加了Altas多地图的支持;同时,回环检测为了支持多地图的模式,提供
  • 如何评价Orbstack(在Mac上低开销地运行容器和Linux)? - 知乎
    orb 命令还提供了其他一些特性,比如可以在虚拟机中 push 或 pull 来传输文件。 目前的一些局限 OrbStack 虚拟的 Linux 是不支持 GUI 的,不过这也不妨碍,我想大部分开发应该只会使用命令行去管理 Linux 运行环境吧。
  • 为何要加载orb vocabulary?他的作用是啥? - 知乎
    ORB-SLAM中已经记录了关键帧的BoW vector,并且还对关键帧库以word_id为索引建立了倒排(class KeyFrameDatabase),这样,在查找与查询帧共享足够多words的关键帧时,就不用遍历所有的关键帧了,只要把查询帧描述符映射的那些words索引的关键帧拎出来就可以了。
  • backtracking - Shattering Orbs - Mathematics Stack Exchange
    As a result, all the orbs below that link will fall and shatter What is the expected number of cuts needed until orb 1 is the only remaining orb? Could someone help me with an elegant solution for the same, my solution is below Attempt-Let's call this a Orb(7) Problem So we need to find Expected Cuts in Orb(7) Problem - Cuts(Orb(7))
  • ORB-SLAM为什么要自己写特征提取的代码而不用opencv自带的呢? - 知乎
    orb-slam系列使用fast关键点提取+orb特征描述子做跟踪、重定位、回环检测。在orb-slam几篇论文中,图像特征提取部分都是一带而过,基本没有详细说明特征提取的方法。但是在实际的代码实现中,这部分内容其实还是做了不少工作的。
  • ORB-SLAM3源码阅读笔记 - 知乎
    ORB-SLAM3源码阅读笔记(1)-Examples 一、ORB-SLAM3的整体流程如下图所示: 相比于ORB-SLAM2,主要的改进在于: 加入了单目+IMU模式和双目+IMU模式。 增加了多地图管理,在跟丢时会新建一个地图,从而提高跟踪的鲁棒性。
  • 为什么互联网档案馆 Archive. org 不能用了? - 知乎
    看到互联网分析里面说 Archive org 可以查看网站历史记录,为什么进不去呢?
  • 单目ORB-SLAM2 跑KITTI数据集的时候怎么做到和ground truth对齐呢?
    单目少pose,而双目正常:对于ORB而言,单目相机需要进行 单目初始化 ,往往第二帧并不能给出一个估计,需要等待几帧。双目的初始化与单目的原理不同,可以马上跟踪出位姿。
  • 为什么像orb slam,vins等视觉SLAM开源算法里,精度上双目常常低于单目? - 知乎
    为什么像orb slam,vins等视觉SLAM开源算法里,精度上双目常常低于单目? 双目能稳定获得尺度,讲道理不是应该精度高一些吗,还是,问题出在标定或特征跟踪上?
