For saving the frame object (data and configuration) from the DepthGenerator node. This frameobject" is a snapshot of the DepthGenerator's generated depth map and its associated configuration information at a certain point in time. This saved frame object provides fast and easy access to the DepthGenerator node's data and configuration information.
It is important to get a good understanding of the purpose and design of the OpenNI metadata objects. For a comprehensive overview of OpenNI metadata objects, see Frame Objects and Metadata Objects.
The DepthGenerator node generates depth data of the FOV. This is the Z-coordinate of the X-Y-Z coordinate of each point. The Z-axis is the distance, in millimeters from the sensor plane. A smaller depth value indicates a scene point that is a closer to the sensor, and a larger depth value indicates a scene point that is further away from the sensor. A zero depth value indicates that the DepthGenerator node did not succeed in obtaining a valid depth reading.
DepthMetaData's xn::DepthMetaData::Data() method provides the actual depth data. This method returns the pointer to the first depth pixel in the map.
The pixel format of depth map is XnDepthPixel, i.e. 16-bit values.
DepthMetaData provides the ZRes property to contain the depth resolution. This is the maximum value of a pixel (plus one).
DepthMetaData is similar to ImageMetaData; they are both metadata for a type of map.

Performs a deep-copy of another metadata object (including duplication of the data buffer).

|
inline |
Returns the depth map.
Remarks
This method returns a pointer to the first depth pixel in the map. The depth map is implemented as a row-major order compact layout of pixels in the map.
The pixel format of the map is XnDepthPixel, i.e. 16-bit integer values.
This method is reimplemented from the xn::OutputMetaData class.
