did anyone confirm it's the actual sensing camera? because that really does just look like a cheap dash cam mounted on the windshield, it's entirely possible it's just that

the Uber cars are supposed to have 360-degree LIDAR

Main Paineframe posted:the Uber cars are supposed to have 360-degree LIDAR yes but they also have a camera under the LIDAR, you can see it in the pictures. like the LIDAR should have caught the person, there's zero excuse for it not, but if it somehow failed i'd still really like to know how the camera didn't

at what stage are Uber self-driving cars meant to be? i mean, if they are currently testing in "world domination" mode, it would make sense that they're using the cheapest cameras and sensors on the market. if their plan is to equip millions of cars with this technology it would explain the poor quality of these images. it's one thing to prove your cars can self-drive with thousand dollar industrial cameras. it's another to make it work just as well with a crappy CMOS

if the highway lobby was able to re-frame fatalities and victim-blame the pedestrian of course this is going to happen with automated cars but twice as fast

# ? Mar 22, 2018 17:17 |

yeah by the time the thing has the light return signal it already has the distance information, which i'd think it actually technically gets before it gets the "brightness" or w/e it uses to reconstruct an "image" (if it even does that) since it's just based on stopping a timer when "i got some light" happens, rather than "collect enough light over this short time period to measure its intensity." that would depend entirely on the internal circuitry though

# ? Mar 22, 2018 17:21 |

it doesn't meaure "brightness" at all; it measures the % amplitude of returned pulse. It uses this in conjunction with time of flight, and a shitload of DSP to determine if it's looking at something kind of reflective, or if it's shooting though, say, a bush, and each leaf will return part of the pulse. It can use this to return multiple "depths" from one pulse. It's real cool poo poo. e: heres an example of a lidar return that likely went through a tree or something, returning multiple targets.

I've worked with one of these things before; slap it on continuous rotation servo, or somethign with a slip-ring, and you can make a little room scanner! https://www.robotshop.com/en/lidar-...pIaAlyVEALw_wcB They're like $150.
