While cameras may be more cost effective than Lidar, they have problems that lidar doesn't. For example, what does the camera sensor do when it's under direct sunlight and can't make sense of what it's seeing? What about rain / fog? I have a feeling google is has the right idea here.

This is great news! I've almost finished building my MAME cabinet. I wonder how this will allow the Roms of those games to be released freely.

Kudos to Atari license holders for releasing this.
