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 detailed example on image stitching can be found at opencv_source_code/samples/cpp/stitching_detailed.cpp

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
	)

Python:
	cv.Stitcher.composePanorama(	[, pano]	) ->	retval, pano
	cv.Stitcher.composePanorama(	images[, pano]	) ->	retval, 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.

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.
try_use_gpu	Flag indicating whether GPU should be used whenever it's possible.

Returns

Stitcher class instance.

createDefault()

static Stitcher cv::Stitcher::createDefault ( bool  try_use_gpu = false )

static

Creates a stitcher with the default parameters.

Parameters
