Detailed Description

A source for using the raw frame API to provide opencv images.

If you are using the WPILib OpenCV builds, do not use this, and instead include "cscore_cv.h" to get a more performant version.

This is not dependent on any opencv binary ABI, and can be used with versions of OpenCV that are not 3. If using OpenCV 3, use CvSource.

Constructor & Destructor Documentation

◆ RawCvSource() [1/3]

cs::RawCvSource::RawCvSource ( )

default

◆ RawCvSource() [2/3]

cs::RawCvSource::RawCvSource	(	std::string_view	name,
		const VideoMode &	mode
	)

inline

Create a Raw OpenCV source.

Parameters

name	Source name (arbitrary unique identifier)
mode	Video mode being generated

◆ RawCvSource() [3/3]

cs::RawCvSource::RawCvSource	(	std::string_view	name,
		VideoMode::PixelFormat	pixelFormat,
		int	width,
		int	height,
		int	fps
	)

inline

Member Function Documentation

◆ PutFrame()

void cs::RawCvSource::PutFrame ( cv::Mat & image )

inline

Put an OpenCV image and notify sinks.

Only 8-bit single-channel or 3-channel (with BGR channel order) images are supported. If the format, depth or channel order is different, use cv::Mat::convertTo() and/or cv::cvtColor() to convert it first.

Parameters

image OpenCV image
