Automatic mapping of devices in a distributed lighting network
View Patent ↗A method includes the steps of obtaining distance measurements between a device and a number of lighting fixtures, processing the distance measurements to assign coordinates to each one of the lighting fixtures, and facilitating registration of the coordinates of a subset of the lighting fixtures to obtain registered coordinates for all of the lighting fixtures. The coordinates indicate a relative location of each one of the lighting fixtures with respect to one another. The registered coordinates indicate a location of each lighting fixture in a desired coordinate space. Accordingly, a location of a lighting fixture within a desired coordinate space can be easily obtained, which may enable significant additional functionality of the lighting fixture.
1. A method comprising:
obtaining a plurality of distance measurements between a plurality of lighting fixtures and a non-lighting fixture device;
verifying the existence of distance measurements between each lighting fixture of the plurality of lighting fixtures and the non-lighting fixture device;
determining a distance measurement for any lighting fixture of the plurality of lighting fixtures not having the distance measurement;
processing the plurality of distance measurements to assign coordinates to each one of the plurality of lighting fixtures, wherein the coordinates indicate a relative location of each one of the plurality of lighting fixtures with respect to one another; and
facilitating registration of the coordinates assigned to a subset of the plurality of lighting fixtures to a coordinate space to obtain registered coordinates for each one of the plurality of lighting fixtures, wherein the registered coordinates indicate a location of a lighting fixture in the coordinate space that corresponds to a floorplan of a structure such that each one of the plurality of lighting fixtures in the subset of the plurality of lighting fixtures is coordinated with respect to each other and the floorplan of the structure via a drag-and-drop operation with respect to the floorplan via a user interface of the non-lighting fixture device, thereby facilitating the registration of the coordinates.
2. The method of claim 1 wherein the plurality of distance measurements are determined based on radio frequency (RF) ranging between the non-lighting fixture device and the plurality of lighting fixtures.
3. The method of claim 1 wherein the plurality of distance measurements are determined based on images captured from a camera on the non-lighting fixture device.
4. The method of claim 1 wherein the plurality of distance measurements are determined based on acoustic ranging between the non-lighting fixture device and the plurality of lighting fixtures.
5. The method of claim 1 wherein processing the plurality of distance measurements to assign the coordinates to each one of the plurality of lighting fixtures comprises processing the plurality of distance measurements using simultaneous localization and mapping (SLAM).
6. The method of claim 5 wherein facilitating the registration of the coordinates assigned to the subset of the plurality of lighting fixtures to the coordinate space comprises facilitating a manual association of the coordinates of the subset of the plurality of lighting fixtures with coordinates in the coordinate space.
7. The method of claim 1 wherein facilitating the registration of the coordinates assigned to the subset of the plurality of lighting fixtures to the coordinate space comprises facilitating a manual association of the coordinates of the subset of the plurality of lighting fixtures with coordinates in the coordinate space.
8. The method of claim 1 further comprising determining locations for each one of the lighting fixtures in the coordinate space based on the coordinates of the lighting fixtures and the registered coordinates of the subset of lighting fixtures.
9. An apparatus comprising:
communications circuitry;
processing circuitry coupled to the communications circuitry; and
a memory storing instructions, which, when executed by the processing circuitry cause the apparatus to:
obtain a plurality of distance measurements between the apparatus and a plurality of lighting fixtures via the communications circuitry where the apparatus is a non-lighting fixture;
verifying the existence of distance measurements between each lighting fixture of the plurality of lighting fixtures and the apparatus;
determining a distance measurement for any lighting fixture of the plurality of lighting fixtures not having the distance measurement;
process the plurality of distance measurements to assign coordinates to each one of the plurality of lighting fixtures, wherein the coordinates indicate a relative location of each one of the plurality of lighting fixtures with respect to one another; and
facilitate registration of the coordinates assigned to a subset of the plurality of lighting fixtures to a coordinate space to obtain registered coordinates for each one of the plurality of lighting fixtures, wherein the registered coordinates indicate a location of a lighting fixture in the coordinate space that corresponds to a floorplan of a structure such that each one of the plurality of lighting fixtures in the subset of the plurality of lighting fixtures is coordinated with respect to each other and the floorplan of the structure via a drag-and-drop operation with respect to the floorplan via a user interface of the apparatus, thereby facilitating the registration of the coordinates.
