Draw axes of the world/object coordinate system from pose estimation. see also: solvePnP

Parameters

• image: Input/output image. It must have 1 or 3 channels. The number of channels is not altered.
• cameraMatrix: Input 3x3 floating-point matrix of camera intrinsic parameters.
• distCoeffs: Input vector of distortion coefficients . If the vector is empty, the zero distortion coefficients are assumed.
• rvec: Rotation vector (see @ref Rodrigues ) that, together with tvec, brings points from the model coordinate system to the camera coordinate system.
• tvec: Translation vector.
• length: Length of the painted axes in the same unit than tvec (usually in meters).
• thickness: Line thickness of the painted axes.

This function draws the axes of the world/object coordinate system w.r.t. to the camera frame. OX is drawn in red, OY in green and OZ in blue.

C++ default parameters

• thickness: 3
