Abstract
A computer implemented method includes capturing images of an environment via a camera, detecting image features in the environment based on the captured images, the image features including at least one web feature derived from a fiducial web formed of a collection of non-repeating intersecting lines applied to an object in the environment, and estimating a camera pose based on the detected image features including the at least one web feature.
Claims20
A computer implemented method comprising:
- capturing images of an environment via a camera;
- detecting image features in the environment based on the captured images, the image features including at least one web feature derived from a fiducial web formed of a collection of non-repeating intersecting lines applied to an object in the environment;
- and
- estimating a camera pose based on the detected image features including the at least one web feature.
A machine-readable storage device having instructions for execution by a processor of a machine to cause the processor to perform operations to perform a method, the operations comprising:
- capturing images of an environment via a camera;
- detecting image features in the environment based on the captured images, the image features including at least one web feature derived from a fiducial web formed of a collection of non-repeating intersecting lines applied to an object in the environment;
- and
- estimating a camera pose based on the detected image features including the at least one web feature.
A device comprising:
- a processor;
- and
- a memory device coupled to the processor and having a program stored thereon for execution by the processor to perform operations comprising:
- capturing images of an environment via a camera;
- detecting image features in the environment based on the captured images, the image features including at least one web feature derived from a fiducial web formed of a collection of non-repeating intersecting lines applied to an object in the environment;
- and
- estimating a camera pose based on the detected image features including the at least one web feature.
