The 4x4 reprojection matrix for the rectified camera coordinate system. The matrix is output as two dimensional Array . You can obtain the 3D coordinates of a point, by applying this matrix to the homogeneous vector containing left image position and disparity (x, y, d, 1). The real coordinates are then obtained by dividing by the homogeneous part of the result.
An array of arrays. Each subarray represents a matrix column.
This node represents the values as they are stored in the cameras eeprom. The actually used reprojection matrix can be found under the Dynamic node.
