Safety glasses verification
View Patent ↗Safety glasses verification methods and devices are described herein. One method in accordance with the present disclosure includes capturing an RGB image of an individual, capturing an infrared (IR) image of the individual, and verifying safety glasses are being worn by the individual based on the RGB image and the IR image.
1. A method for verifying safety glasses, comprising:
capturing an RGB image of an individual;
capturing an infrared (IR) image of the individual; and
verifying, by a safety glasses verification device, safety glasses are being properly worn by the individual based on the RGB image and the IR image by:
detecting a location of an eye of the individual in the RGB image;
detecting a location of safety glasses in the IR image, wherein:
the safety glasses include a single T-shaped material corresponding exclusively to a center of a frame of the safety glasses; and
the single T-shaped material is visible in the IR image and not visible in the RGB image; and
verifying that the location of the eye of the individual in the RGB image corresponds to the location of the safety glasses in the IR image.
2. The method of claim 1 , wherein detecting the location of the eye of the individual in the RGB image includes:
detecting a position of the individual's head in the RGB image; and
inferring the location of the eye of the individual in the RGB image based on the position of the individual's head in the RGB image.
3. The method of claim 1 , wherein verifying safety glasses are being properly worn by the individual includes verifying that the safety glasses are covering both eyes of the individual.
4. The method of claim 1 , wherein the method includes capturing the RGB image and the IR image using a single camera.
5. The method of claim 1 , wherein the method includes:
capturing the RGB image using a first camera; and
capturing the IR image using a second camera.
6. The method of claim 1 , wherein the IR image of the individual is a corresponding IR image of the RGB image of the individual.
7. The method of claim 1 , wherein the method includes capturing the RGB image and the IR image simultaneously.
8. A safety glasses verification device, comprising:
a camera configured to capture an RGB image of an individual and an infrared (IR) image of the individual;
a memory; and
a processor configured to execute executable instructions stored in the memory to:
detect a location of an eye of the individual in the RGB image;
detect a location of safety glasses in the IR image, wherein:
the safety glasses include a single T-shaped material corresponding exclusively to a center of a frame of the safety glasses; and
the single T-shaped material is visible in the IR image and not visible in the RGB image; and
verify that the location of the eye of the individual in the RGB image corresponds to the location of the safety glasses in the IR image to verify that the safety glasses are being properly worn by the individual.
9. The safety glasses verification device of claim 8 , wherein the processor is configured to execute the instructions to verify that the location of the eye of the individual in the RGB image corresponds to the location of the safety glasses in the IR image by registering the RGB image and the IR image.
10. The safety glasses verification device of claim 9 , wherein registering the RGB image and the IR image includes matching the RGB image and the IR image according to reference points common to each image.
11. The safety glasses verification device of claim 8 , wherein the memory is configured to store the RGB image and the IR image.
12. The safety glasses verification device of claim 8 , wherein the processor is configured to execute the instructions to flag a safety violation if the location of the eye of the individual in the RGB image does not correspond to the location of the safety glasses in the IR image.
13. The safety glasses verification device of claim 8 , wherein the processor is configured to execute the instructions to biometrically detect the location of the eye of the individual in the RGB image.
14. A safety glasses verification device, comprising:
a camera configured to capture an RGB image of an individual and an infrared (IR) image of the individual;
a memory; and
a processor configured to execute executable instructions stored in the memory to verify safety glasses are being properly worn by the individual based on the RGB image and the IR image by:
detecting a location of an eye of the individual in the RGB image;
detecting a location of safety glasses in the IR image, wherein the safety glasses include a material that is:
a single T-shaped material corresponding exclusively to a center of a frame of the safety glasses;
visible in the IR image; and
not visible in the RGB image; and
verifying that the location of the eye of the individual in the RGB image corresponds to the location of the safety glasses in the IR image.
15. The safety glasses verification device of claim 14 , wherein the material includes an IR-absorbing substance.
16. The safety glasses verification device of claim 14 , wherein the material is a film impregnated with an IR-absorbing substance.
17. The safety glasses verification device of claim 14 , wherein the material forms a portion of the center of the frame of the safety glasses.
18. The safety glasses verification device of claim 14 , wherein the material is placed on the center of the frame of the safety glasses.
