Abstract
For scanning optical patterns, such as two-dimensional QR codes, with a mobile device at increased distances, a first image is acquired. A region of interest likely containing the optical pattern in the first image is identified. The mobile device then zooms in on the region of interest and a second image is acquired. The optical pattern is then decoded using the second image.
Claims20
A system comprising:
- a camera;
- and
- one or more processors configured to:
- acquire, using the camera, a first image of a scene, wherein the scene includes a person;
- detecting a body part of the person in the first image;
- predicting a region of interest in the scene based on a position of the body part in the first image;
- transmit instructions to the camera to change a field of view and/or a focus of the camera, to zoom to and/or to focus on the region of interest;
- acquire, using the camera, a second image, wherein the second image is acquired after the instructions to change the field of view and/or the focus of the camera;
- localize, in the second image, an optical pattern in the region of interest;
- decode the optical pattern to generate pattern data;
- and saving the pattern data to a memory device.

A method comprising:
- acquiring, using a camera, a first image of a scene, wherein the scene includes a person;
- detecting a body part of the person in the first image;
- predicting a region of interest in the scene based on a position of the body part in the first image;
- transmitting instructions to the camera to change a field of view or a focus of the camera, to zoom to or to focus on the region of interest;
- acquiring, using the camera, a second image, wherein the second image is acquired after the instructions to change the field of view or the focus of the camera;
- localizing, in the second image, an optical pattern in the region of interest;
- decoding the optical pattern to generate pattern data;
- saving the pattern data to a memory device.
5 more elements
A memory device comprising instructions that, when executed, perform the following steps:
- acquiring, using a camera, a first image of a scene, wherein the scene includes a person;
- detecting a body part of the person in the first image;
- predicting a region of interest in the scene based on a position of the body part in the first image;
- transmitting instructions to the camera to change a field of view or a focus of the camera, to zoom to or to focus on the region of interest;
- acquiring, using the camera, a second image, wherein the second image is acquired after the instructions to change the field of view or the focus of the camera;
- localizing, in the second image, an optical pattern in the region of interest;
- decoding the optical pattern to generate pattern data;
- and
- saving the pattern data to the memory device or a different memory device.
