Title:
AUTO-ALIGNMENT OF IMAGE SENSORS IN A MULTI-CAMERA SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/142412
Kind Code:
A3
Abstract:
A pair of cameras having an overlapping field of view is aligned based on images captured by image sensors of the pair of cameras. A pixel shift is identified between the images. Based on the identified pixel shift, a calibration is applied to one or both of the pair of cameras. To determine the pixel shift, the camera applies correlation methods including edge matching. Calibrating the pair of cameras may include adjusting a read window on an image sensor. The pixel shift can also be used to determine a time lag, which can be used to synchronize subsequent image captures.
