scan-to-map匹配是激光雷达中一个基础的概念,scan是当前帧,map是当前帧时空维度上临近的帧组成的集合。map已经经过不断地优化,有一定精度了,而当前帧只有一个初始的估计位姿。至于怎么来的,可以是用前一帧位姿+运动计算,也可以是有外部传感器IMU、轮式里程计等得到的,总之它是不准确的。那么我们可以将当前帧的激光
第三篇:Scan to Map Match 本篇主要讲述Scan to map方法Scan to map ,即激光雷达扫描数据直接与地图进行匹配,得到实际位置坐标[x,y,theta]。这种方式一边计算位置,一边把新扫描到的数据及时加入到先前地图中。…
grid-mapmappingKullback-Leibler divergenceThis paper presents a grid-based scan-to-map matching technique for accurate 2D map building. At every acquisition of a new scan, the proposed technique matches the new scan to the previous scan similarly to the conventional techniques, but further corrects...
1:已知上一时刻的地图m,也是未完成的submap。因为scan to map的过程,就是scan to current submap的过程。 2:submap是栅格地图,这是为了方便匹配。 3:机器人在任意时刻,都能看到map上的所有occupied points。但是,scan不一定能扫描到所有的点。 4:matching的过程,实际上就是把scan的所有扫描数据,映射到当前的subm...

Using a for loop, add scans to the SLAM object. The object uses scan matching to compare each added scan to previously added ones. To improve the map, the object optimizes the pose graph whenever it detects a loop closure. Every 10 scans, display the stored poses and scans. Get for ...
