Detailed Description

this class is used To Detect circles in an image

using this class you can detect x, y and radius of a circle in an image after calling DetectColor::processImage there are many possible ways to get The output for example you can connect the signal ImageProcessor::DetectCircle::circlesDetected to any QObject Slot that takes std::vector<cv::Vec3f> as a parameter another way is to use the return of processImage and convert the QVarient to std::vector<cv::Vec3f>

 connect(crcleDetector, &DetectCircle::circlesDetected, [=](const std::vector<cv::Vec3f>& vec){
     for_each(vec.begin(), vec.end(), [](cv::Vec3f v){ qDebug() << v[0] << ", " << v[1] << ", " << v[2];});
});
 std::vector<cv::Vec3f> vec = crcleDetector.processImage().value<std::vector<cv::Vec3f>>(); //and prints each x, y, r of every circle.

Member Function Documentation

◆ circlesDetected

ImageProcessor::DetectCircle::circlesDetected ( const std::vector< cv::Vec3f > & )

signal

this signal is emitted after detecting All the circles in the image being processed.

can Be connected with other objects to get the circles in an image.

connect(crcleDetector, &DetectCircle::circlesDetected, [=](const std::vector<cv::Vec3f>& vec){
     for_each(vec.begin(), vec.end(), [](cv::Vec3f v){ qDebug() << v[0] << ", " << v[1] << ", " << v[2];});
}; //prints each x, y, r of every circle.

◆ detectCircle()

std::vector< cv::Vec3f > DetectCircle::detectCircle ( ) const

this helper Function is used to detect circles in an Image using HoughCircle Algorithm.

Returns: a vector of 3 points vector each represents the x, y, r of all circles in the image.

See also: ImageProcessor::DetectCirlce::processImage.

Definition at line 66 of file detectcircle.cpp.

◆ processImage()

QVariant DetectCircle::processImage ( )

overridevirtual

reimplemented Function.

this function is reimplented to process a thresholded image of grayscale type to Detect All Cirlces.

See also: ImageProcessor::AbstractImageProcessor::processImage

Returns: std::vector<cv::Vec3f> a vector of cv::Vec3f where each index in it represents a circle which centers are x, y and radius.
using circleVec = std::vector<cv::Vec3f>;
auto i = circleDetector.processImage().value<circleVec>();
for(auto a : i){
qDebug() << "x = " << a[0] << ", y = " << a[1] << ", r = " << a[2]; //should iterate on each element and prints it's x, y, and radius.
}

Implements ImageProcessor::AbstractImageProcessor.
