Abstract
A head-mounted device (HMD) is structured to include at least one computer vision camera that omits an IR light filter. Consequently, this computer vision's sensor is able to detect IR light, including IR laser light, in the environment. The HMD is configured to generate an image of the environment using the computer vision camera. This image is then fed as input into a machine learning (ML) algorithm that identifies IR laser light, which is detected by the sensor and which is recorded in the image. The HMD then visually displays a notification comprising information corresponding to the detected IR laser light.
Claims20
A head-mounted device (HMD) configured to detect infrared (IR) laser light being emitted in an environment, said HMD comprising:
- at least one computer vision camera that omits an IR light filter such that a sensor of the at least one computer vision camera is operable to detect IR light, including IR laser light, in the environment;
- one or more processors;
- and
- one or more computer-readable hardware storage devices that store instructions that are executable by the one or more processors to cause the HMD to at least:
- generate an image of the environment using the at least one computer vision camera;
- feed the image as input to a machine learning (ML) algorithm, said ML algorithm being configured to identify IR laser light that is detected by the sensor of the at least one computer vision camera and that is recorded in the image;
- and
- visually display a notification comprising information corresponding to the detected IR laser light.
A method for detecting infrared (IR) laser light being emitted in an environment, said method being performed by a head-mounted device (HMD) configured to include at least one computer vision camera that omits an IR light filter such that a sensor of the at least one computer vision camera is operable to detect IR light, including IR laser light, in the environment, said method comprising:
- generating an image of the environment using the at least one computer vision camera;
- feeding the image as input to a machine learning (ML) algorithm, said ML algorithm being configured to identify IR laser light that is detected by the sensor of the at least one computer vision camera and that is recorded in the image;
- and
- visually displaying a notification comprising information corresponding to the detected IR laser light.
A head-mounted device (HMD) configured to detect collimated infrared (IR) light being emitted in an environment, said HMD comprising:
- at least one computer vision camera that omits an IR light filter such that a sensor of the at least one computer vision camera is operable to detect IR light, including collimated IR light, in the environment;
- one or more processors;
- and
- one or more computer-readable hardware storage devices that store instructions that are executable by the one or more processors to cause the HMD to at least:
- generate a first image of the environment using the at least one computer vision camera;
- generate a second image of the environment using a thermal imaging camera;
- feed the first image as input to a machine learning (ML) algorithm, said ML algorithm being configured to identify collimated IR light that is detected by the sensor of the at least one computer vision camera and that is recorded in the first image;
- reproject the second image to compensate for parallax between a pupil of a user wearing the HMD and the thermal imaging camera;
- reproject the identified collimated IR light to compensate for parallax between the user's pupil and the at least one computer vision camera;
- overlay the reprojected collimated IR light onto the reprojected second image to generate an overlaid image;
- and
- visually display the overlaid image.
