Abstract
A method for determining an orientation of a photosensor of a controller with respect to a projector is described. The method includes generating, by a beam generator of the projector, a beam. The method further includes modifying a direction of travel of the beam using a micro-electro-mechanical systems (MEMS) mirror that moves in a pattern, detecting the beam, calculating a time at which the beam is detected, and determining based on the pattern and the time an orientation of the beam to determine the orientation of the photosensor.
Claims20
A method for determining an orientation of a photosensor with respect to a projector, comprising:
- generating, by a beam generator of a projector, a beam;
- modifying a direction of travel of the beam using a micro-electro-mechanical systems (MEMS) mirror that moves in a pattern;
- detecting, by a photosensor, the beam;
- calculating a time of hit at which the beam is detected;
- and
- determining based on the pattern and the time of hit an orientation of the photosensor with respect to the projector.
A system for determining an orientation of a photosensor with respect to a projector, comprising:
- a projector including a beam generator configured to generate a beam,
- wherein the projector includes a micro-electro-mechanical systems (MEMS) mirror configured to move in a pattern to modify a direction of travel of the beam;
- a controller is communication with the projector, wherein the controller has a photosensor, wherein the photosensor is configured to detect the beam, wherein the controller is configured to calculate a time of hit at which the beam is detected;
- and
- a computing device in communication with the projector and the controller, wherein the computing device is configured to determine based on the pattern and the time of hit an orientation of the photosensor with respect to the projector.
A system comprising:
- a controller having a photosensor, wherein the photosensor is configured to detect a beam to generate a detected beam hit signal, wherein the controller is configured to calculate a time of hit at which the beam is detected;
- and
- a computing device in communication with the controller, wherein the computing device is configured to determine based on a pattern of motion of a micro-electro-mechanical systems (MEMS) mirror and the time of hit an orientation of the beam with respect to an xyz co-ordinate system.
