Finds lines segments in a binary image using probabilistic Hough transform.
Namespace: OpenCvSharp.CPlusPlus
Assembly: OpenCvSharp.CPlusPlus (in OpenCvSharp.CPlusPlus.dll) Version: 1.0.0.0 (1.0.0.0)
Syntax
public CvLineSegmentPoint[] HoughLinesP( double rho, double theta, int threshold, double minLineLength = 0, double maxLineGap = 0 )
Parameters
- rho
- Type: SystemDouble
Distance resolution of the accumulator in pixels - theta
- Type: SystemDouble
Angle resolution of the accumulator in radians - threshold
- Type: SystemInt32
The accumulator threshold parameter. Only those lines are returned that get enough votes ( > threshold ) - minLineLength (Optional)
- Type: SystemDouble
The minimum line length. Line segments shorter than that will be rejected. [By default this is 0] - maxLineGap (Optional)
- Type: SystemDouble
The maximum allowed gap between points on the same line to link them. [By default this is 0]
Return Value
Type: CvLineSegmentPointThe output lines. Each line is represented by a 4-element vector (x1, y1, x2, y2)
