Panoramic Image Stitcher for ComfyUI

Simple Node to make panoramic images using OpenCV stitch function

This node is available on ComfyUI Manager

PARAMETERS

Name	Description
device	Improved performance only if using it in flow, since OpenCV functions run only on the CPU
crop	Crops the smallest acceptable area with perspective warp pixels
mode	Switches between panoramic mode (default) or scans mode, optimized for documents and images with details such as letters
threshold	Decreases the precision to create stitch points, but can cause errors, see FAQ

FAQ

• Error 1

Occurs when the stitcher cannot find the stitch points between the images (the stitcher function algorithm needs it to return an average of equality points to join the image. Increasing the number of images and decreasing the spacing between them avoids this problem

• Error 3

It happens when the threshold is too low. Always use the default value 1.0 and go down to refine. In the tests carried out there was little gain in the reduction of warp perspective by lowering this parameter.

Next features

• Improvements in code redundancy between some functions.
• Impement the mask as alpha directly in the image.
