The fusing step is very straightforward and pretty much how I imagined it would be done. This is new? Also I still don’t get how Tesla can take the stance that cameras only is the way to go... I really thought redundancy was a no brainer here...https://twitter.com/math_rachel/status/1204100054681870336 …
“Lidar is really a shortcut," added Tesla AI guru Andrej Karpathy. "It sidesteps the fundamental problems of visual recognition that is necessary for autonomy. It gives a false sense of progress, and is ultimately a crutch." https://arstechnica.com/cars/2019/08/elon-musk-says-driverless-cars-dont-need-lidar-experts-arent-so-sure/?amp=1 …
^^ this just seems like a really strange position. Why not both...? There are some things cameras simply can’t do!
It’s pretty much a race to see whether Tesla’s camera-only approach will be good enough (= better than humans where deployed) before LIDAR can be cheap enough to put on mass production cars
LIDAR add a lot of cost - easily $5000 per LIDAR
Not just cameras though. There is also 12 ultrasonic and radar sensors.
That’s much better then. The Arstechnica article keeps going on about how they interviewed other experts who say camera only is a bad idea and were talking about a camera only paper. Hence the confusion....
I guess there are other reasons as well, like cost, because they intend to sell privately owned vehicles as opposed to a lot of other companies that are targeting at ride-sharing fleet. Anyway, Musk has given valid reasons for going against LiDAR in cars (they use it in Dragon)
Also, a lot of people emphasize on the 3D detection capability of LiDAR and used it as an advantage over camera, but Tesla has shown some demonstrations on their depth sending capabilities from cameras itself, the argument is these kind of things need more research efforts.
@math_rachel SpaceX uses Lidar. Im sure Elon has seen the other side that we haven’t.
