US 2013/0258115 A1 · METHOD FOR CALIBRATING A CAMERA

Abstract

A method calibrates a camera having image sensor having a center position. An image view projected onto the image sensor by a lens is captured. At least one image view boundary of the captured image view is detected. A projection center position corresponding to a center of the projected image view is determined in at least one dimension. Offset between the projection center position and a sensor center position is determined, defined in at least one dimension, corresponding to the center of the image sensor capturing the projected image view. The image sensor is moved in relation to the lens based on the offset in order to arrive at a substantially zero offset in at least one dimension between the center of image sensor and the center of the projected image view.

Dependent claims

A method for calibrating a camera including an image sensor having a center position, the method comprising:

capturing an image view projected onto the image sensor by a lens, the projected image view having a center,
detecting at least one image view boundary of the image view captured by the image sensor,
determining, in at least one dimension, a projection center position corresponding to the center of the projected image view on the image sensor based on detected boundary,
determining offset between the projection center position and the sensor center position, defined in at least one dimension, corresponding to the center of the image sensor capturing the projected image view, and
moving the image sensor in relation to the lens based on the offset in order to arrive at a substantially zero offset in at least one dimension between the center of image sensor and the center of the projected image view.
