Abstract
An exemplary method includes defining an environment, formulating an anti-keystoning algorithm based at least in part on the defined environment, projecting a laser image from a source to a surface of the defined environment, determining at least one vector parameter with respect to the source and the surface and correcting the laser image based on the anti-keystoning algorithm and the at least one vector parameter. Various other apparatuses, systems, methods, etc., are also disclosed.
Claims26
A method comprising:
- defining a model for an environment;
- projecting a laser image from a source to a surface of the environment;
- determining at least one vector parameter with respect to the source and the surface;
- and
- correcting the laser image based on the model, an anti-keystoning algorithm and the at least one vector parameter.
2 more elements
An apparatus comprising:
- source lasers configured to project an image;
- localization circuitry;
- one or more processors;
- control circuitry configured to
- define a model for an environment based on receipt of localization information received from the localization circuitry;
- localize the source lasers with respect to a modeled surface of the environment;
- and
- correct an image projected from the source lasers to a surface of the environment based on the localization of the source lasers and an anti-keystoning algorithm.
5 more elements
A method comprising:
- projecting a laser image from a source to a surface of an environment;
- registering a marker with respect to the laser image, the marker associated with a pointing device;
- and
- executing an instruction based on the registering.
