How’s a Lidar is a national risk?! (It’s easy to build a lidar based drones in a weekend project) Also, knowing plenty of US based drone manufacturers, most of their stuff are dependent on Chinese parts, the radio communication is on top of that list. If I were DJI, I would make Lidar and similar components modular, so they can still sell these drones while consumers can buy these modules later or DIY it, like literally most of the drones, which will be great for other consumers in the world for the easy repairability.
- ranger_danger 2mo ago> How’s a Lidar is a national risk?! The anti-flock community believes it's because they can destroy image sensors from a distance. And banning the foreign ones means they can order domestic-made drones to have firmware that prevents them from operating in certain ways or in certain (government) areas, among other things. The finance community thinks they just don't want competition that might rival or sell better than domestic ones, similar to the ban on Chinese EVs. The privacy community thinks they only want surveillance to be possible from within, likening it to previous bans on DJI drones and Chinese routers. And the administration is currently working on trying to ban other kinds of networking gear as well as cellular modems from China (which is basically every phone in the country). Would love to hear other theories. Perspectives are fun.
- 05 2mo ago> And banning the foreign ones means they can order domestic-made drones to have firmware that prevents them from operating in certain (government) areas, among other things. Yeah because DJI drones are well known for their easy to hack firmware and lacking support for no fly zones..right? And they would openly flaunt any US law making any drones sold or flown the US to obey the NFZs? But wait, that's exactly what DJI drones used to do even without a law on the books, before FCC banned them.
- ranger_danger 2mo agoNFZ was just one example, there's no limit to what they could force other countries' software to do in their domestic versions. That was really the point I was trying to make.
- OutOfHere 2mo agoBackdoors and tracking.
- cherioo 2mo agoI am sure if the US gov asks DJI to do those things they will be happy to comply. They are just here to make money.
- greenavocado 2mo agoSteel manning this argument: Electronic warfare resistant loitering munitions. They would transmit sparse point clouds to the enemy for training. Not saying I support it.
- anigbrowl 2mo agoHow is this worse than 4k video, in this age of analytical abundance? The steel content of this argument is pretty low; it's essentially 'technology operates normally = national security risk.' Why not ban pencils? You can draw maps or schematics of secret things, plus they can be used to stab people!

- monster_truck 2mo ago4k 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.
- snypher 2mo ago>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.
- greenavocado 2mo agoCompare the energy cost of computation for SfM compared to sparse point cloud match

- onetimeusename 2mo agoI don't think it's LiDAR itself that is the risk. The FCC note read more like the cause is trade and supply-chain protectionism. (https://www.fcc.gov/sites/default/files/robots-nsd.pdf https://www.fcc.gov/sites/default/files/robots-nsd.pdf)
- theptip 2mo agoThe obvious concern would be China building high-res maps of every inch of US cities.
- tamimio 2mo agoBuy an iPhone, download an app (polycam, scaniverse, strayscanner, etc), build professional grade point clouds/maps. Technology itself is everywhere.
- Danox 2mo agoThat boat has sailed for all of the countries that have the technological capability and it has gotten even better with the advent of AI because now you can correlate the information at a even higher level faster and that ability is only getting better every day. In short, there are no real secrets geographically at least not for long. What’s more important is that you have the rare earth minerals inventory and even that is not a secret.
- fc417fc802 2mo agoThey already have that, and us maps of their country as well. Everyone has maps of everything at this point. If it's above ground then literally everyone that matters knows about it.
- theptip 2mo agoI don’t think that lidar maps are public knowledge. If they were why would Google be spending so much money creating their own? This is not the same thing as taking a picture from a satellite.
- fc417fc802 2mo agoI realize that. I didn't say "publicly available" but rather that anyone important has access to the information that they want. I expect that any exceptions to that can be trivially remedied on a case by case basis. It's a matter of scale. Satellite imagery gets you most of the way there. I can think of only a very few instances where you'd care about higher resolution and those should be few enough that any well funded actor (ie the ones we care about here) can perform targeted data collection.
