関数詳解

◆ detect()

virtual CV_WRAP void cv::ximgproc::FastLineDetector::detect ( InputArray  image,
OutputArray  lines 
)
pure virtual

Finds lines in the input image. This is the output of the default parameters of the algorithm on the above shown image.

image

引数
imageA grayscale (CV_8UC1) input image. If only a roi needs to be selected, use: fld_ptr-\>detect(image(roi), lines, ...); lines += Scalar(roi.x, roi.y, roi.x, roi.y);
linesA vector of Vec4f elements specifying the beginning and ending point of a line. Where Vec4f is (x1, y1, x2, y2), point 1 is the start, point 2 - end. Returned lines are directed so that the brighter side is on their left.

◆ drawSegments()

virtual CV_WRAP void cv::ximgproc::FastLineDetector::drawSegments ( InputOutputArray  image,
InputArray  lines,
bool  draw_arrow = false,
Scalar  linecolor = Scalar(0, 0, 255),
int  linethickness = 1 
)
pure virtual

Draws the line segments on a given image.

引数
imageThe image, where the lines will be drawn. Should be bigger or equal to the image, where the lines were found.
linesA vector of the lines that needed to be drawn.
draw_arrowIf true, arrow heads will be drawn.
linecolorLine color.
linethicknessLine thickness.
