about rotate to camera coordinates

[92ypli]

Hello, how do you understand this matrix?
# Rotate to camera coordinates
R = np.array([[0., -1., 0., 0.],
[0., 0., -1., 0.],
[1., 0., 0., 0.],
[0., 0., 0., 1.]])
In other words, how do I rotate the axes to get this matrix?

As I understand it, it should be rotated 90 degrees counterclockwise along the X axis and 90 degrees clockwise along the y axis,
but, i get below matrix：
R = np.array([[0., -1., 0., 0.],
[0., 0., 1., 0.],
[-1., 0., 0., 0.],
[0., 0., 0., 1.]])
