When i export / import XML of camera view using meshlab, I got rotation matrix and translation matrix, but what's the format of this params? Is it c2w or w2c? I don't notice any description about this parameters.

In CV, camera pose consitst of position and rotation. Position refers to the 3D location in which the camera take photos, and rotation refers to the attitude, which is represneted by three angles rotating about the 3 axes and can be denoted by an orthogonal matrix. In CG, position and rotation can be integerated into one 4X4 matrix by introducing Homogeneous Coordinates. you can relate to https://docs.opencv.org/2.4/modules/calib3d/doc/camera_calibration_and_3d_reconstruction.html for more details.
