I'm reading this survey on the state-of-the-art techniques for indoor positioning and navigation. I noticed that LIDAR isn't mentioned at all in the paper. Is LIDAR not meant to be a common method for indoor navigation? I believe I've seen some industrial LIDAR robots some time ago though.

  • $\begingroup$ The article is mostly about positioning in indoor settings. LIDAR by itself gives no position; and using SLAM will give you a position relative to a perceived map, but not an absolute position. $\endgroup$ – Juancho Aug 7 '19 at 22:42
  • $\begingroup$ @Juancho But don't many techniques reviewed also need perceived maps? For instance, Bluetooth and WLAN methods need perceived signal strength maps. $\endgroup$ – John M. Aug 8 '19 at 4:06

    $\begingroup$ Lidar isn't used for positioning, it's used for navigation. $\endgroup$ – tuskiomi Aug 8 '19 at 13:10

    $\begingroup$ @tuskiomi Yes, I believe that paper covers both. $\endgroup$ – John M. Aug 8 '19 at 14:14
  • $\begingroup$ 2D LiDAR or LRF sensors are common for indoor navigation (e.g. Hokuyo URG or Hokuyo UTM) $\endgroup$ – Benyamin Jafari Aug 8 '19 at 15:13

I think LiDAR is common for indoor navigation. Definitely, LiDAR is the easiest and accurate solution for indoor navigation or SLAM. Many commercial robot vacuums are already in use of LiDAR for indoor navigation and mapping. Those are even cheaper and simpler than RGBD modules which is why low-cost LiDARs are hired over RGBD in mass production models.

It is just that indoor navigation is a vast topic. I haven't seen any survey paper that covers all types of sensors. We can't cover few thousands of papers in a single survey paper. The paper you linked has some specific coverage and it is ok not to mention other sensors out of the scope such as LiDAR or camera.

  • $\begingroup$ It does cover visual SLAM, I believe. $\endgroup$ – John M. Aug 8 '19 at 15:08
