The 1st Automated cam

1st automated cam success (1 min 46 sec)

The answer is yes. Automated cams work. They're not completely foolproof, but with enough error protection can do a decent job. The 1st automated cam ended up being LIDAR based. The trick with LIDAR was building dense point clouds out of many passes.

All the basic limitations of XV-11 LIDAR apply. It only detects horizontal motion, not vertical. It only works indoors. It can't handle lots of mirrors & windows. It can't detect anything more than 4m away. It can't handle 2 simultaneous sources of motion. It does better at night than daytime with sunlight coming in. The worst case is the camera pans away from the subject.

The less ideal conditions can be handled by classifying more pixels as outliers, but this makes the camera lag more. The room had a small number of windows which still resulted in a usable amount of lag. It tracked for 45 minutes at night without any failures. As the subject moves farther away, the harder it is to get the camera to track with the amount of filtering required for the windows. It's very limiting to not have vertical tracking.

There's still a plan to try a machine vision approach, with its own set of limitations. A thermal cam might do it, but these are extremely expensive.

When the mobile app billionaires finally get automated cams fast enough & reliable enough for the masses, they're going to be a game changer just like brushless gimbals. GPS quad copters won't do it. Cheaper LIDAR is the key.
