Claim One:
1. A method for calibrating an event-based camera, the method comprising: receiving a calibration image comprising intensity information for a set of image elements defining the calibration image, the intensity information defining a calibration pattern; iteratively, until a threshold number of different image elements of the set of image elements have been projected: selecting a portion of the calibration image corresponding to a subset of image elements of the set of image elements, the subset comprising less than all image elements in the set of image elements, the selected portion comprising at least one image element not previously selected; projecting the selected portion of the calibration image onto a sensor of the event-based camera based on the intensity information; detecting, by the sensor, the selected portion of the calibration image; generating a set of detected pixels corresponding to the detecting of the selected portion of the calibration image; and discontinuing projection of the selected portion; and determining, for a first position of the event-based camera relative to the projecting, at least one calibration parameter using the generated sets of detected pixels.
