Abstract
A method of stitching frames captured at multiple viewing angles comprising: receiving a set of frames captured by imagers, identifying in each of pairs of neighboring frames, each neighboring frame is captured about the same time as the other from an imager having an overlapping field of view with another. For each overlapping area a center connecting axis connecting between centers of respective the pair of neighboring frames is identified, a motion gradient for each frame of the pair of neighboring frames is calculated, pixels of the pair of neighboring frames in the at least one overlapping area are adapted based on corresponding values from the motion gradient along the center connecting axis, the pair of adapted neighboring frames into a panoramic frame which at least partly imaging an environment surrounding the common center is stitched.
