在手眼标定过程中,需借助罗德里格斯公式来求解与旋转矩阵相对应的旋转轴
rodrigues.m文件的具体内容如下:

复制代码
    function	[out,dout]=rodrigues(in)
    
    % RODRIGUES	Transform rotation matrix into rotation vector and viceversa.
    %		
    %		Sintax:  [OUT]=RODRIGUES(IN)
    % 		If IN is a 3x3 rotation matrix then OUT is the
    %		corresponding 3x1 rotation vector
    % 		if IN is a rotation 3-vector then OUT is the 
    %		corresponding 3x3 rotation matrix
    %
