Open, Needs TriagePublic

Description

This issue is to research options for external autofocus that can be added to any camera and (manual) lens.

There are different technologies to measure the distance to an object:

The most accurate technology seems LIDAR, that's why it's used in self-driving cars.

There are some commercial lidar systems.

It would be awesome if we could build an open hardware solid-state LIDAR. Maybe there are some research papers we could implement. We could collaborate with open hardware self-driving car projects. Maybe some university is interested in such a project.

One practical use of such a system for video would be conference recording. Today a camera person has to follow the speaker and keep focus. With a system to move the camera like a gimbal or robot arm and LIDAR focus it can be fully automated!
