Abstract
Calibration for a camera is achieved by receiving images of a calibration object whose geometry is one-dimension in space. The received images show the calibration object in several distinct positions. Calibration for the camera is then calculated based on the received images of the calibration object.
Claims11
In a computer system, a method comprising:
- receiving images of a calibration object whose geometry is one-dimension in space, the received images showing the calibration object in several distinct positions, wherein:
- the calibration object comprises three or more collinear points with known relative positions between the points;
- and
- at least one of the collinear points remains fixed with respect to the other points in the received images showing the calibration object in several distinct position;
- and
- calculating a calibration for a camera based on the received images of the calibration object.
3 more elements
A method, comprising:
- imaging a one-dimensional object in six or more distinct configurations, the imaging performed by an object imaging device, wherein the one-dimensional object comprises three or more collinear points with known relative positions between the points and wherein at least one of the collinear points remains fixed with respect to the other points in the received images showing the calibration object in several distinct positions;
- and
- estimating unknown parameters associated with object imaging device by computing parameters associated with imaging the one-dimensional object in the six or more distinct configurations.
A system, comprising:
- means for imaging a one-dimensional object in six or more distinct configurations;
- and
- means for estimating unknown parameters associated with object imaging device by computing parameters associated with imaging the one-dimensional object in the six or more distinct configurations, wherein the one-dimensional object comprises three or more collinear points with known relative positions between the points and wherein at least one of the collinear points is fixed.
