question: public Camera ( Matrix intr ) { intrinsics = intr ; distCoeffs = new Matrix ( new double [ ] { 0 , 0 , 0 , 0 } , 1 ) ; invIntrinsics = intr . inverse ( ) ; cx = intrinsics . get ( 0 , 2 ) ; cy = intrinsics . get ( 1 , 2 ) ; fx = intrinsics . get ( 0 , 0 ) ; fy = intrinsics . get ( 1 , 1 ) ; k1 = k2 = p1 = p2 = 0 ; }
target:  Create a new camera with a given camera matrix and no distortion.
