US 2022/0191995 A1 · SYSTEMS AND METHODS FOR DETERMINING LIGHTING FIXTURE ARRANGEMENT INFORMATION

Abstract

Systems and methods for determining lighting fixture arrangement information (e.g., position and/or orientation). A lighting beam from the lighting fixture is directed among three discrete locations on a reference surface (e.g., by a controller). The fixture's position is determined using perspective inversion based on angular changes of the lighting fixture and coordinate data of the discrete locations (e.g., determined using a camera and a reference point on the surface). Distances from the fixture to the three discrete locations are estimated based on perspective inversion. The position of the lighting fixture is trilateralized based on the distances. Spherical coordinates of the fixture's orientation relative to the reference surface are determined, and yaw, pitch, and roll of the fixture are extracted.

Dependent claims

A method of determining arrangement information of a lighting fixture, the method comprising:

storing in a memory, by an electronic processor, angular change data of the lighting fixture each time a direction of a lighting beam from the lighting fixture is varied among each of at least three discrete locations on a reference surface;
determining, with the electronic processor, coordinate data of each of the at least three discrete locations on the reference surface;
storing in memory, with the electronic processor, the coordinate data;
and
determining, with the electronic processor, a position of the lighting fixture based on the coordinate data and the angular change data.

A system for determining arrangement information of a lighting fixture, the system comprising:

a controller including an electronic processor and a memory coupled to the electronic processor, the memory storing instructions that when executed by the electronic processor configure the controller to:
determine angular change data of the lighting fixture each time a direction of a lighting beam from the lighting fixture is varied between at least three locations on a surface,
determine coordinate data of the lighting beam for each of the at least three locations on the surface,
calculate a respective distance between the lighting fixture and each of the at least three locations based on the angular change data and the coordinate data,
determine a position of the lighting fixture based on the respective distances, and
output positional data indicating the position of the lighting fixture.
