Abstract
A method for detecting a marker in a camera image is described. In one aspect, a method includes accessing a camera image generated by an optical sensor of an augmented reality (AR) device, accessing a query image from a storage of the AR device, and identifying, using a feature detector program, the query image in the camera image without scaling the camera image.
Claims20
A method comprising:
- accessing a camera image generated by an optical sensor of an augmented reality (AR) device;
- accessing a query image from a storage of the AR device;
- and
- identifying, using a feature detector program, the query image in the camera image without scaling the camera image.
A computing apparatus comprising:
- a processor;
- and
- a memory storing instructions that, when executed by the processor, configure the apparatus to:
- access a camera image generated by an optical sensor of an augmented reality (AR) device;
- access a query image from a storage of the AR device;
- and
- identify, using a feature detector program, the query image in the camera image without scaling the camera image.
A non-transitory computer-readable storage medium, the computer-readable storage medium including instructions that when executed by a computer, cause the computer to:
- access a camera image generated by an optical sensor of an augmented reality (AR) device;
- access a query image from a storage of the AR device;
- and
- identify, using a feature detector program, the query image in the camera image without scaling the camera image.
