ArucoInvokeDrawAxis Method

http://www.emgu.com

Given the pose estimation of a marker or board, this function draws the axis of the world coordinate system, i.e. the system centered on the marker/board. Useful for debugging purposes.

Parameters

image: Type: Emgu.CVIInputOutputArray
input/output image. It must have 1 or 3 channels. The number of channels is not altered.
cameraMatrix: Type: Emgu.CVIInputArray
input 3x3 floating-point camera matrix
distCoeffs: Type: Emgu.CVIInputArray
vector of distortion coefficients (k1,k2,p1,p2[,k3[,k4,k5,k6],[s1,s2,s3,s4]]) of 4, 5, 8 or 12 elements
rvec: Type: Emgu.CVIInputArray
rotation vector of the coordinate system that will be drawn.
tvec: Type: Emgu.CVIInputArray
translation vector of the coordinate system that will be drawn.
length: Type: SystemSingle
length of the painted axis in the same unit than tvec (usually in meters)
