This was probably true in 2016, but not anymore. Waymo’s 5th gen lidar and Argo AI’s lidar all show massive performance and resolution improvements. They have been game changers. Anyone not using lidar in 2021 is just handicapping themselves, as we are seeing with Tesla FSD performance.
- kjksf 5y agoCan you quantify the improvements for us? As far as I know the specs for Waymo's 5th generation lidar are not publicly available. Can you link to them? How much work did you do with Waymo's 5th generation lidar? Or any lidar for that matter? Do you have any qualifications to claim that a lidar that isn't even available to you is capable of doing a very specific task?
- ra7 5y agoThe specs are not publicly available, but the comparison to their 4th gen lidar is. As you can see in [1], the resolution improvement is massive, which is what the GP was claiming lidars lack. I don't see a "ton of signal to noise ratio" in the sensor data either as claimed. Same with Argo AI's lidar [2]. If you want to hear from an expert (which I am not), here is Brad Templeton talking about Waymo and Argo's lidar improvements [3].
