Safety feature for projection subsystem using laser technology

摘要

A projection subsystem includes a projector for projecting an image on a projection surface and a safety feature for tuning the projector when presence of a human is detected in front of the projection surface. This safety feature includes: —an apparatus for computing a depth view corresponding to at least a portion of the projection surface, —a camera for acquiring a captured image, —a computing circuit for detecting an object between the projector and the projection surface from this depth view and determining that the object is a human from the captured image, and a control circuit for tuning the projector accordingly.
