Absolutely yes there is. Even the single point laser rangefinders like what are linked in the top comment here now are useful for consumer drones.
The hack people used to do (maybe still do?) was to combine a laser pointer and a webcam, and infer the distance based on where in the Y axis the laser appeared in the image that the webcam received.
This, which is many points in many directions, is much, much better, and it sounds like it will be cheap (at least much cheaper than these devices have been).
- ThatGeoGuy 9y agoOne counter objection: LiDAR on drone will be a whole lot less useful if they all 1) collect the same frequency of EM, and 2) have any way of picking up scattered signals from other drones (because it was pointed at other drones, or from scattered reflections). Right now there's not much in the way of LiDAR on anything, but once there is, we will need to find ways to stop other active sensors from interfering with our own.
