Abstract

A method and a device for stitching images and blending pixel data of respective images from each of at least three image sensors during a time period when an object passes through a combined view of the at least three image sensors. The combined view is a combination of a respective view of each of the at least three image sensors, and comprises a first region in which at least three of the views of the at least three image sensors overlap and through which the track passes. The method comprises obtaining a respective sequence of images from each of the at least three image sensors, detecting the object in the combined view, determining a location of the detected object, predicting a track of the object, identifying a minimal view set covering all portions of the track, and stitching and blending images captured at a same point in time from each of the sequences of images to a combined image corresponding to the combined view. The stitching and blending is such that, in a major proportion of a first portion of the combined image corresponding to the first region of the combined view, blending is performed using pixel data only from respective images from at most two image sensors and only from image sensors having views comprised in the minimal view set.
