import { fisheye_initUndistortRectifyMap } from '@banou/opencv-wasm'

Use after await initOpenCV(). See the initialization and named imports guide.

ARGUMENTSK, D, R, P
FUNCTIONfisheye_initUndistortRectifyMap
RETURN TYPEvoid
Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Computes undistortion and rectification maps for image transform by cv::remap(). If D is empty zero distortion is used, if R or P is empty identity matrixes are used.

fisheye_initUndistortRectifyMap(K: Mat, D: Mat, R: Mat, P: Mat, size: Size, m1type: number, map1: Mat, map2: Mat): void;
K

Camera intrinsic matrix cameramatrix{K}.

D

Input vector of distortion coefficients \distcoeffsfisheye.

R

Rectification transformation in the object space: 3x3 1-channel, or vector: 3x1/1x3 1-channel or 1x1 3-channel

P

New camera intrinsic matrix (3x3) or new projection matrix (3x4)

size

Undistorted image size.

m1type

Type of the first output map that can be CV_32FC1 or CV_16SC2 . See convertMaps() for details.

map1

Output destination, filled by the native operation. The first output map.

map2

Output destination, filled by the native operation. The second output map.
