Unprojects a 2d point in 3d.
tfg.rendering.camera.orthographic.unproject(
point_2d,
depth,
name=None
)
Defined in rendering/camera/orthographic.py.
Unprojects a 2d point \((x', y')\) to a 3d point \((x, y, z)\) given its depth \(z\), with
$$
\begin{matrix}
x = x', & y = y', & z = z.
\end{matrix}
$$
Note:
In the following, A1 to An are optional batch dimensions.
Args:
point_2d: A tensor of shape[A1, ..., An, 2], where the last dimension represents a 2d point to unproject.depth: A tensor of shape[A1, ..., An, 1], where the last dimension represents the depth of a 2d point.name: A name for this op that defaults to "orthographic_unproject".
Returns:
A tensor of shape [A1, ..., An, 3], where the last dimension represents
a 3d point.
Raises:
ValueError: If the shape ofpoint_2d,depthis not supported.
