4k video is worthless compared to LiDAR. You are never going to get sub millisecond dead reckoning from video processing. Previously this required things like extremely expensive, export controlled ring laser gyroscopes (they do not drift and cannot be easily interfered with or jammed like the cheap IMU in your phone) There are many more reasons LiDAR kicks ass but none of them have anything to do with why they are doing this.

>4k video is worthless compared to LiDAR. You should do some more research into structure-from-motion and get back to us. Lidar is nice for real-time data, but these days anyone can process a 4k stream and get excellent geometry data.

    This is pretty marginal compared to the energy cost of keeping the drone and its payload in the air; also the original objection was that the data might get used for training, which can be an offline process. For example, you could fly a drone with 4k cameras around while navigating manually, then subsequently compute an environmental model from the recorded footage. If a hypothetical hostile and weaponized drone is later deployed with a pretrained navigational model, it might have 4k and/or LIDAR whose function would be to verify rather than figure out navigation; in a state of hostility we can assume the owners of the drone would be indifferent to local rules.

  You're not doing that to 4k60 in microsecond timeframes brother, especially not for driftless navigation

What exactly the threat model here, that makes Lidar data dangerous? Space-based remote sensing is superior in almost every way.

  If I had to reach for something I would have to guess they're attempting to hinder their use in renewables. Generally speaking they are not too popular in weapons because shooting a bunch of lasers out of your nose is not exactly stealthy Before we had these, wind farms used to have to poach cell phone tower guys to climb up every single one. Had a neighbor who did this, it pays insanely well but my palms sweat just thinking about it.
