Unprojects a 2d point in 3d.
tfg.rendering.camera.orthographic.unproject(
point_2d: type_alias.TensorLike,
depth: type_alias.TensorLike,
name: str = 'orthographic_unproject'
) -> tf.Tensor
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 of point_2d, depth is not supported.
