/** * 基于相关方法的scan-to-map匹配 * 1、用前一帧优化前后的位姿变换,来校正当前帧优化前的位姿,得到一个初始位姿 * 2、提取局部map中当前帧也可以看到的点,对应栅格设置为占用 * 剔除相对于当前帧属于物体背面的点,也就是近邻帧与当前帧在物体两面 * 3、scan-to-map匹配 * 1) 创建旋转角度-激光点...

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...
Scan-to-map matching using the Hausdorff distance for robust mobile robot localization 来自 掌桥科研 喜欢 0 阅读量: 110 作者:M Torres-Torriti,A Guesalaga 摘要: This paper presents a robust method for localization of mobile robots in environments that may be cluttered and that not necessarily ...
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...
I find out that GORM cast byte arrays to strings, ifColumnTypeScanType elseifbok:=mapValuecolumnRawBytes);ok This behaviour was introduced in 2020 and actually it's not clear why it do so. I thing it's logical that if db value is sql.RawBytes, then it should return[]byte, not stri...
A CUDA reimplementation of the line/plane odometry of LIO-SAM. A point cloud hash map (inspired by iVox of Faster-LIO) on GPU is used to accelerate 5-neighbour KNN search. - qdLMF/LIO-SAM-GPU-ScanToMapOpt

aAdd folder or disk you want to scan. The data will be displayed as a color-coded sunburst map which clearly shows the size of each file or folder. It becomes quite easy for you to catch the space hogs. Information about each files or folder will also be displayed in the side bar on...
aThe red flight lines over the scan area indicate the direction the UX5 will fly across the scan area. The unmanned aircraft always flies perpendicular to the prevailing wind direction. By default, the prevailing wind direction is a northerly wind. North is located at the top of the map. ...
