stitchingclassOpenCV 5.0.0

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

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

Native object: release it with using or delete(). Factories can return null; check before calling methods.

Constructors and members

static new

Create an owned PyRotationWarper object. Release native handles with using or delete().

new(): PyRotationWarper;

2 available overloads

new(_0: EmbindString, scale: number): PyRotationWarper;

new(): PyRotationWarper;

_0: 0 argument (EmbindString).
scale: scale argument (number).

Returns

The PyRotationWarper result.

Upstream declaration ↗Upstream declaration 2 ↗

clone

Create another handle to the same native object. This retains the object without copying its pixels or algorithm state; dispose both handles separately.

clone(): this;

Returns

The this result.

warpPoint

Projects the image point.

warpPoint(pt: Point2f, K: Mat, R: Mat): Point2f;

pt: Source point
K: Camera intrinsic parameters
R: Camera rotation matrix

Returns

Projected point

Upstream declaration ↗

warpPointBackward

Projects the image point backward.

warpPointBackward(pt: Point2f, K: Mat, R: Mat): Point2f;

pt: Projected point
K: Camera intrinsic parameters
R: Camera rotation matrix

Returns

Backward-projected point

Upstream declaration ↗

buildMaps

Builds the projection maps according to the given camera data.

buildMaps(src_size: Size, K: Mat, R: Mat, xmap: Mat, ymap: Mat): Rect;

src_size: Source image size
K: Camera intrinsic parameters
R: Camera rotation matrix
xmap: Output destination, filled by the native operation. Projection map for the x axis
ymap: Output destination, filled by the native operation. Projection map for the y axis

Returns

Projected image minimum bounding box

Upstream declaration ↗

warp

Projects the image.

warp(src: Mat, K: Mat, R: Mat, interp_mode: number, border_mode: number, dst: Mat): Point;

src: Source image
K: Camera intrinsic parameters
R: Camera rotation matrix
interp_mode: Interpolation mode
border_mode: Border extrapolation mode
dst: Output destination, filled by the native operation. Projected image

Returns

Project image top-left corner

Upstream declaration ↗

warpBackward

Projects the image backward.

warpBackward(src: Mat, K: Mat, R: Mat, interp_mode: number, border_mode: number, dst_size: Size, dst: Mat): void;

src: Projected image
K: Camera intrinsic parameters
R: Camera rotation matrix
interp_mode: Interpolation mode
border_mode: Border extrapolation mode
dst_size: Backward-projected image size
dst: Output destination, filled by the native operation. Backward-projected image

Upstream declaration ↗

warpRoi

Compute the integer bounding rectangle of an image warped using the supplied intrinsic matrix and camera rotation.

warpRoi(src_size: Size, K: Mat, R: Mat): Rect;

src_size: Source image bounding box
K: Camera intrinsic parameters
R: Camera rotation matrix

Returns

Projected image minimum bounding box

Upstream declaration ↗

getScale

Return the scale configured on this PyRotationWarper object.

getScale(): number;

Returns

The number result.

Upstream declaration ↗

setScale

Set the scale used by this PyRotationWarper object.

setScale(arg1: number): void;

arg1: arg1 argument (number).
