Detailed Description

High level image stitcher.

It's possible to use this class without being aware of the entire stitching pipeline. However, to be able to achieve higher stitching stability and quality of the final images at least being familiar with the theory is recommended.

Note

A basic example on image stitching can be found at opencv_source_code/samples/cpp/stitching.cpp
A basic example on image stitching in Python can be found at opencv_source_code/samples/python/stitching.py
A detailed example on image stitching can be found at opencv_source_code/samples/cpp/stitching_detailed.cpp

◆ Mode

enum cv::Stitcher::Mode

Enumerator

PANORAMA

Mode for creating photo panoramas.

Expects images under perspective transformation and projects resulting pano to sphere.

SCANS

Mode for composing scans.

Expects images under affine transformation does not compensate exposure by default.

◆ composePanorama() [1/2]

Status cv::Stitcher::composePanorama ( OutputArray pano )

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

◆ composePanorama() [2/2]

Status cv::Stitcher::composePanorama	(	InputArrayOfArrays	images,
		OutputArray	pano
	)

These functions try to compose the given images (or images stored internally from the other function calls) into the final pano under the assumption that the image transformations were estimated before.

Note: Use the functions only if you're aware of the stitching pipeline, otherwise use Stitcher::stitch.

Parameters

images	Input images.
pano	Final pano.

Returns: Status code.

◆ compositingResol()

inline

◆ create()

static Ptr<Stitcher> cv::Stitcher::create ( Mode mode = Stitcher::PANORAMA )

static

Creates a Stitcher configured in one of the stitching modes.

Parameters

mode	Scenario for stitcher operation. This is usually determined by source of images to stitch and their transformation. Default parameters will be chosen for operation in given scenario.

Returns: Stitcher class instance.

◆ estimateTransform()

Status cv::Stitcher::estimateTransform	(	InputArrayOfArrays	images,
		InputArrayOfArrays	masks = `noArray()`
	)

These functions try to match the given images and to estimate rotations of each camera.

Note: Use the functions only if you're aware of the stitching pipeline, otherwise use Stitcher::stitch.

Parameters

images	Input images.
masks	Masks for each input image specifying where to look for keypoints (optional).

Returns: Status code.
