Real time image stiching

I need to stitch several large images together
I using the sticher class and that works well however as far as timing in the system goes it seems to be the bottleneck,
what needs to be stitched are images from an array of stationary cameras that do not change position or angle from each other, as well the objects it needs to stitch are at a set distance as well and mostly flat upright against a wall.
what i’m wondering is given that I already when where the images are in relation to each other is using the sticher class the optimal approach for what im trying to do?

yes, I believe so. I’m not familiar with the stitching module but it does suggest that you can separate the matching/alignment from the compositing.
