| ) |
Construct using all of the camera parameters.
Must satisfy the following requirements: x,y_scales must be > 0, focal_length must be not equal to 0.
Definition at line 28 of file vpgl_calibration_matrix.txx.
| vpgl_calibration_matrix< T >::vpgl_calibration_matrix | ( | const vnl_matrix_fixed< T, 3, 3 > & | K | ) |
Construct from a right upper triangular matrix whose decomposition into the calibration components makes sense.
The supplied matrix can be a scalar multiple of such a matrix.
