computer vision - Matlab Camera Calibration - How do i go from rotation vector to rotation matrix

问题描述:

I am trying set up a rotation matrix from my Matlab Camera Calibration data, trying to understand the theory behind the data. Could anyone here explain to me how to go from rotational vectors to rotational matrix?

From what I have gathered so far, I need atleast 3 rotational vectors to get a good rotational matrix?

If i pick these 3 first rotational vectors from my single camera calibration session, can i get an rotational matrix from this?

Rotation vectors:

[0.1152 0.1273 0.0173]

[0.0165 0.2087 -0.0941]

[-0.0852 0.0118 0.0277]

From reading questions on these forum and others I have understood that I probably have to use the rodrigues formula to do so, but as I am new to this I need some help getting a grip around this.

Last question: are the rotational vectors given in radians, and the camera rotation In Matlab given medians?
