Inputs (6)

Name	Type	Default	Description
points1	NPARRAY		Array of N points from the first image. The point coordinates should be floating-point (single or double precision). A data array (points / matrix), NOT an image - only an NPARRAY link is accepted here.
points2	NPARRAY		Array of the second image points of the same size and format as points1 . A data array (points / matrix), NOT an image - only an NPARRAY link is accepted here.
methodopt	COMBO	FM_RANSAC	Method for computing a fundamental matrix. - for a 7-point algorithm. $N = 7$ - for an 8-point algorithm. $N \ge 8$ - for the RANSAC algorithm. $N \ge 8$ - for the LMedS algorithm. $N \ge 8$
ransacReprojThresholdopt	FLOAT	3.0000-1e+38–1e+38	Parameter used only for RANSAC. It is the maximum distance from a point to an epipolar line in pixels, beyond which the point is considered an outlier and is not used for computing the final fundamental matrix. It can be set to something like 1-3, depending on the accuracy of the point localization, image resolution, and the image noise. Preset to the OpenCV default (3.0).
confidenceopt	FLOAT	0.9900-1e+38–1e+38	Parameter used for the RANSAC and LMedS methods only. It specifies a desirable level of confidence (probability) that the estimated matrix is correct. Preset to the OpenCV default (0.99).
maskopt	NPARRAY,IMAGE,MASK		- - - Accepts a ComfyUI IMAGE/MASK directly (frame 0 of a batch) or an NPARRAY. Arithmetic ops (add, multiply, etc.) process the full IMAGE batch when both inputs have the same batch size.
