What is the practical solution for cameras only besides sensors with more dynamic range? Secondary cameras with faster apertures and higher ISOs(or different exposure settings)? Would that also help by allowing triangulation for distances and minimizing false positives for stationary objects? It is more of a technology or cost problem?
- KaiserPro 5y agoGood question. Tesla already have limited number of sensors, and they do most of the driving using monocular(single camera, or single viewpoint with three different zoom levels) inference. This is absolute madness, given the state of current tech. For that night situation, I would be pushing for a different camera type. One that doesn't have a global exposure setting. This means that groups of pixels can be lumped together to have local ISO settings(its more complex than that, and involves integrating processing silicon directly under the sensor, on the same die.). This is a way to get vastly greater dynamic range in a situation where you have lots of point lights (ie headlights) This would require developing and qualifying a new camera sensor from scratch (I don't think generic versions of this type of camera exist yet) Musk is unlikely to do this as he has signaled that everything should be done via ML. Second, using a different wavelength, IR, or near IR. Thirdly, higher wavelength radar. It gives you this information for free, they are cheap and already qualified for vehicles.
