Abstract

An augmented reality-based lighting design method includes displaying, by an augmented reality device, a real-time image of a target physical area on a display screen. The method further includes displaying, by the augmented reality device, a lighting fixture 3-D model on the display screen in response to a user input, where the lighting fixture 3-D model is overlaid on the real-time image of the target physical area. The method also includes displaying, by the augmented reality device, a lighting pattern on the display screen overlaid on the real-time image of the target physical area, wherein the lighting pattern is generated based on at least photometric data associated with the lighting fixture 3-D model.

First claim

What is claimed is:

1 . An augmented reality-based lighting design method, comprising:
detecting, by an augmented reality device, an existing light fixture installed in an area displayed on a display screen; determining, by the augmented reality device, one or more surfaces in the area using image data; determining, by the augmented reality device, one or more replacement light fixtures at least based on a type of the existing light fixture and the one or more surfaces; and displaying, on a display screen of the augmented reality device, a lighting fixture model of a replacement light fixture from among the one or more replacement light fixtures, and wherein the lighting fixture model is overlaid on a real-time image of the area displayed on the display screen.

2 . The method of claim 1 , further comprising displaying illuminance values overlaid on the one or more surfaces of the area in the real-time image of the area.

3 . The method of claim 2 , wherein one or more of the illuminance values are determined based on at least photometric data associated with the lighting fixture model of the replacement light fixture and spatial relationship between the one or more surfaces and the replacement light fixture model.

4 . The method of claim 1 , wherein the lighting fixture model of the replacement light fixture is overlaid on the real-time image at a location of the existing light fixture in response to a user input provided to the augmented reality device selecting the lighting fixture model of the replacement light fixture from among one or more lighting fixture models of the one or more replacement light fixtures.

5 . The method of claim 1 , wherein determining the one or more replacement light fixtures is performed further based on a spatial relationship between the existing light fixture and the one or more surfaces.

6 . The method of claim 1 , further comprising:
determining, by the augmented reality device, a second one or more replacement light fixtures at least based on a type of a second existing light fixture and the one or more surfaces; and displaying, overlaid on the real-time image of the area displayed on the display screen, a second lighting fixture model of a second replacement light fixture from among the second one or more replacement light fixtures, wherein the second existing light fixture is replaceable by the second replacement light fixture.

7 . The method of claim 6 , further comprising displaying illuminance values overlaid on the one or more surfaces of the area displayed on the display screen, wherein the illuminance values are determined based on at least photometric data associated with the lighting fixture model, photometric data associated with the second lighting fixture model, and spatial relationships of the light fixture model and the second light fixture model with the one or more surfaces.

8 . The method of claim 1 , further comprising, determining, by the augmented reality device, the type of the existing light fixture based on at least the image data, wherein a type of the replacement light fixture is same as the type of the existing light fixture.

9 . The method of claim 1 , further comprising, determining, by the augmented reality device, the type of the existing light fixture based on at least the image data, wherein a type of the replacement light fixture is different than the type of the existing light fixture.

10 . The method of claim 1 , further comprising, measuring, by a sensor included on the AR device, an illuminance value observed in the area.

11 . The method of claim 1 , further comprising, generating a bill of material that includes an identifier of the replacement light fixture.

12 . An augmented reality (AR) device, comprising:
a camera to capture a real-time image of an area; a sensor; a display screen; a memory device storing a software code; and a controller configured to execute the software code to:
detect an existing light fixture installed in the area using image data from the camera;
determine one or more surfaces in the area using the sensor and the image data from the camera;
determine one or more replacement light fixtures at least based on a type of the existing light fixture and the one or more surfaces; and
display, overlaid on the real-time image of the area displayed on the display screen, a lighting fixture model of a replacement light fixture from among the one or more replacement light fixtures.

13 . The AR device of claim 12 , wherein the controller is further configured to display illuminance values overlaid on the one or more surfaces displayed on the display screen.

14 . The AR device of claim 13 , wherein the controller is further configured to determine the one or more of the illuminance values based on at least photometric data associated with the replacement light fixture and spatial relationship between the replacement light fixture and the one or more surfaces.

15 . The AR device of claim 12 , wherein the controller is further configured to determine the type of the existing light fixture based on at least the image data from the camera.

16 . An augmented reality-based lighting design method, comprising:
determining, by the augmented reality device, one or more surfaces in the area using image data; determining, by the augmented reality device, one or more replacement light fixtures at least based on the one or more surfaces; and displaying, on a display screen of the augmented reality device, a lighting fixture model of a replacement light fixture from among the one or more replacement light fixtures, and wherein the lighting fixture model is overlaid on a real-time image of the area displayed on the display screen.

17 . The method of claim 16 , further comprising displaying illuminance values overlaid on the one or more surfaces of the area in the real-time image of the area.

18 . The method of claim 17 , wherein one or more of the illuminance values are determined based on at least photometric data associated with the lighting fixture model of the replacement light fixture and spatial relationship between the one or more surfaces and the replacement light fixture model.

19 . The method of claim 17 , further comprising, measuring, by a sensor included on the AR device, an illuminance value observed in the area.

20 . The method of claim 16 , further comprising, generating a bill of material that includes an identifier of the replacement light fixture.
