WebORB-SLAM2的局部建图线程LocalMapping分为5个步骤，非常简单。当得到缓冲队列里的关键帧，第一步处理当前关键帧的地图点关系等；第二步判断地图点是否为新创建，如果是那就进入测试，测试地图点的好坏，如果不好的地图点就舍弃；第三步创建新地图点，这里创建的是局部地图（真正会被注册到 ... WebStep 1 构建旋转直方图 Step 2 在半径窗口内搜索当前帧F2中所有的候选匹配特征点 Step 3 遍历搜索搜索窗口中的所有潜在的匹配候选点，找到最优的和次优的 Step 4 对最优次优结果进行检查，满足阈值、最优/次优比例，删除重复匹配 Step 5 计算匹配点旋转角度差所在的直方图 Step 6 筛除旋转直方图中“非主流”部分 Step 7 将最后通过筛选的匹配好的特征点保存 … WebApr 15, 2024 · orb slam2详解_奥维地图导入数据格式ORBSLAM2真是个神奇的算法。他开源了，但是各种不实用。这大概就是学术和工作的区别吧。人家毕竟花了一整个博士阶段去开发这个算法，我们还是应该心存感激。实验室里用的相机是ZED的双目相机，所以为了这个相机，我做了自己的双目相机数据包和接口，发现 ... how many miles in a nautical mile
