However, traditional SLAM methods based on a monocular camera only perform well in simple indoor environments or urban environments with obvious structural features. In off-road environments, the situation that SLAM encounters could be complicated by problems such as direct sunlight, leaf occlusion, ...
\lambda q_i+q_i\times q'_i={}^B R_w {}^wP_i+{}^Bt_w 如果估计的pose相对于上一帧运动较大,则进一步地对当前帧进行local map跟踪(与ORBSLAM相似)。最后,如果跟踪到的路标点数量小于特定阈值,则将当前帧添加为关键帧。当添加新关键帧时,会添加观测到已有的路标点中,并三角化新的地图点。 后端...
ORB-SLAM-VI[4]首次提出了一种可视化惯性SLAM系统,该系统能够重用具有短期、中期和长期数据关联的地图,并在基于IMU预集成的精确局部视觉惯性BA中使用它们[61],[62]。然而,它的IMU初始化技术太慢,需要15秒,这损害了健壮性和准确性。[63]和[64]中提出了更快的初始化技术,基于闭合形式的解决方案,联合检索尺度、...
In addition, we include a performance evaluation on accurate ground truth and compare the robustness of the proposed method to a single camera version of the SLAM system. An open source implementation of the proposed multi-fisheye camera SLAM system can be found on-line this https URL . 展开 ...

ORB-SLAM3: An Accurate Open-Source Library for Visual, Visual-Inertial and Multi-Map SLAM,摘要-本文提出了ORB-SLAM3,第一个系统能够执行视觉,视觉惯导以及多地图的SLAM系统,且该系统具有单目,双目,RGB-D相机模型,用针孔相机和鱼眼镜头模型。第一个主要的创新是
3. Camera calibration We use a rather generic camera model, and thus MultiCol-SLAM should work with any prevalent central camera. To calibrate your cameras follow the instructions onlink. The systems expects a calibration file with the following structure: ...

IV. CAMERA MODEL 本节将相机模型从 SLAM 管道中抽象出来,提取与相机模型相关的属性和函数,包括投影和反投影函数、雅可比等。由于流行的计算机视觉算法假设了针孔模型,SLAM 系统需要进行图像矫正或者像素坐标矫正,以在理想成像平面上工作。然而,鱼眼镜头的 FOV 可达 180 度或更多。图像矫正会导致边缘物体被放大而中心物...
