professor_rumsdiegeige Posted February 27, 2009 Report Share Posted February 27, 2009 Hello! Has anybody got some hints on how to perform image stitching using Labview? I.e. I've got a couple of overlapping small images and would like to merge them into a global (bigger) image. If this is not available in Labview, do you happen to know of another library with which this is possible? Please note: I know there are ready-to-use programs that do exactly that, but I need the functionality in my own program. Regards Sabine Lorentz Quote Link to comment
rpursley Posted February 27, 2009 Report Share Posted February 27, 2009 I've only successfully done it by integrating calls to Photoshop from LabVIEW. I do not know of any LabVIEW toolkits for this.

I've got a couple of overlapping small images and would like to merge them into a global (bigger) image. If the images are parallel (i.e. NOT the standard wider-angle panorama from a camera) then a simple approach would be to use routines in the Vision Development Module. A possible algorithm would be to compute the cross-correlation between neighbouring images, and then place each image at an appropriate location within a larger canvas. An enhancement would be to cross-fade between the images where they overlap. Where there are any significant lens distortions, then a much more complex algorithm is required, although if you know the distortion of your system, it would not be difficult to correct your images for that prior to stitching.
