Specifies the region of pixels in the disparity map for which depth data should be computed during ComputeDisparityMap. The AOI size also reduces the size of the rectified images, as well as the DisparityMap and PointMap images.



A parameter sub tree. Please refer to the description of the sub nodes for further information.


Setting a new stereo matching AOI immediately clears and resizes the affected image nodes.


The AOI is always defined in unscaled image coordinates (i.e. with Scaling = 1 and Binning = 1). Thus the full AOI always corresponds to the camera’s sensor resolution, regardless of scaling and binning factors. You can look up the actual AOI in scaled coordinates in the ScaledAreaOfInterest node.
