20、 is the cheapest and smallest sensor setup. However as depth is not observable from just one camera,the scale of the map and estimated trajectory is unknown.In addition the system bootstrapping require multi-view or filtering techniques to produce an initial map as it cannot be triangulated from the

21、 very first frame. Last but not least,monocular SLAM suffers from scale drift and may fail if performing pure rotations in exploration. By using a stereo or an RGB-D camera all these issues are solved and allows for the most reliable Visual SLAM solutions.可以通过只使用单目相机来实现视觉SLAM，这是最便宜和最小的传感器设备。 然而，由于仅从

22、一个摄像机无法观察到深度，因此地图的比例和估计的轨迹是未知的。此外，系统不能从第一帧进行三角测量，需要多视图或滤波技术来产生初始地图。 最后，但最重要的是单目SLAM会受到比例漂移的影响，如果在勘探中进行纯旋转，可能会失败。 通过使用立体声或RGB-D相机，所有这些问题都得到了解决，并提供了最可靠的视觉 SLAM解决方案。16、5G will have to support a multitude of new applications with a wide variety of requirements, including higher peak and user data rates,
