The Ledger
Every statement that passed quotation and attribution checks. Mix any filter with any other: certainty 1/5, debate potential 5/5, or both at once.
why aren't all 7 resolved? a statement only gets an assessment when the public record can support or contradict it. opinions and what-ifs never can, and 0 checkable ones are still open, waiting for their date. predictions held up or didn't; assertions are supported or contradicted. on every card: ▮▮▮▮▮ certainty · ▮▮▮▮▮ debate potential. speakers are clickable
Wei Lowe: Cameras alone cannot provide high-precision depth perception for AVs
“When you're talking about extreme high precision measurement cameras oftentimes is just not enough. And the lasers gives you a precise measurement of depth or distance in the three D space.”
Wei Lowe: Consumer digital maps rely on survey fleets, not crowdsourcing
“Those maps were not created from The GPS unit that you have on your car or the camera system that you have in your car and whatnot. They were created by special, what we call mapping survey fleets.”
Wei Lowe: Modern digital maps are built exclusively for human consumption
“But if you actually dive deeper, maps today, including the digital maps, are actually built for human consumption only.”
Wei Lowe: Cloud infrastructure handles 99% of HD map computation
“Of course, it's the automated storage place, and it's also the place where 99% of the computation is done for map creation and map updates.”
Wei Lowe: China and South Korea explicitly forbid exporting geospatial mapping data
“There are countries who heavily, heavily regulate their geospatial data. You know, China is one, South Korea is one. There's actually a whole bunch of other countries who... Explicitly Forbid exporting geospatial data. You cannot move data out of South Korea a…”
Wei Lowe: HD maps for autonomous vehicles require centimeter-level accuracy
“The maps that are purposely built for self-driving purpose are usually called high definition maps or high or HD map for short. This specifically referred to the maps that have extremely high precision. And we're talking about centimeter level accuracy or prec…”
