Results of Image Stitching

Image/Video data from multiple cameras was captured real time. A stage wise stitching result is shown below:

As from above result it is evident that there is distinctive exposure and focus difference between two adjacent cameras making it easy for any viewer to identify the different camera images. An ideal way to fix this is to be able to program same exposure value and focus value in both cameras. Since, we don't have access to programmable camera drivers, We tried to fix exposure difference using Seam and Blending functions in software. To optimize our processing seam and blending function were applied only after we are done stitching images from all 6 cameras.

Once a 360 degree stitched image is attained, a seam function is applied to diminish the boundaries between images.
