fit_single_line(depth, predicted_depth, target=None)

Fit a single line to the depth map using the predicted depth map.

\[egin{align*} egin{bmatrix} predicted\_depth & 1 \end{bmatrix} egin{bmatrix} k \ b \end{bmatrix} = depth \end{align*}\]

Parameters:

• depth (ndarray) – the observed depth map.

• predicted_depth (ndarray) – the predicted depth map.

• target (ndarray | None) – the target depth map to transform.

Returns:

the transformed depth map. If target is not None, we will return k * target + b. Otherwise, we will return k * predicted_depth + b.
