Namespace: OpenCvSharp.CPlusPlus
Assembly: OpenCvSharp.CPlusPlus (in OpenCvSharp.CPlusPlus.dll) Version: 1.0.0.0 (1.0.0.0)
Syntax
public static void SolvePnP( InputArray objectPoints, InputArray imagePoints, InputArray cameraMatrix, InputArray distCoeffs, OutputArray rvec, OutputArray tvec, bool useExtrinsicGuess = false, SolvePnPFlag flags = SolvePnPFlag.Iterative )
Parameters
- objectPoints
- Type: OpenCvSharp.CPlusPlusInputArray
Array of object points in the object coordinate space, 3xN/Nx3 1-channel or 1xN/Nx1 3-channel, where N is the number of points. vector<Point3f> can be also passed here. - imagePoints
- Type: OpenCvSharp.CPlusPlusInputArray
Array of corresponding image points, 2xN/Nx2 1-channel or 1xN/Nx1 2-channel, where N is the number of points. vector<Point2f> can be also passed here. - cameraMatrix
- Type: OpenCvSharp.CPlusPlusInputArray
Input camera matrix - distCoeffs
- Type: OpenCvSharp.CPlusPlusInputArray
Input vector of distortion coefficients (k_1, k_2, p_1, p_2[, k_3[, k_4, k_5, k_6]]) of 4, 5, or 8 elements. If the vector is null, the zero distortion coefficients are assumed. - rvec
- Type: OpenCvSharp.CPlusPlusOutputArray
Output rotation vector that, together with tvec , brings points from the model coordinate system to the camera coordinate system. - tvec
- Type: OpenCvSharp.CPlusPlusOutputArray
Output translation vector. - useExtrinsicGuess (Optional)
- Type: SystemBoolean
If true, the function uses the provided rvec and tvec values as initial approximations of the rotation and translation vectors, respectively, and further optimizes them. - flags (Optional)
- Type: OpenCvSharp.CPlusPlusSolvePnPFlag
