StereoSGBM Properties

Gets or sets a memory address allocated by AllocMemory.

Gets or sets the byte length of the allocated memory

(Inherited from StereoMatcher.)

Native pointer of OpenCV structure

Gets or sets a handle which allocates using cvSetData.

(Inherited from StereoMatcher.)

Returns true if the Algorithm is empty (e.g. in the very beginning or after unsuccessful read

Gets a value indicating whether this instance has been disposed.

Gets or sets a value indicating whether you permit disposing this instance.

Set it to StereoSGBM::MODE_HH to run the full-scale two-pass dynamic programming algorithm. It will consume O(W\*H\*numDisparities) bytes, which is large for 640x480 stereo and huge for HD-size pictures. By default, it is set to false .

The first parameter controlling the disparity smoothness. See P2 description.

The second parameter controlling the disparity smoothness. The larger the values are, the smoother the disparity is. P1 is the penalty on the disparity change by plus or minus 1 between neighbor pixels. P2 is the penalty on the disparity change by more than 1 between neighbor pixels. The algorithm requires P2 \> P1 . See stereo_match.cpp sample where some reasonably good P1 and P2 values are shown (like 8\*number_of_image_channels\*SADWindowSize\*SADWindowSize and 32\*number_of_image_channels\*SADWindowSize\*SADWindowSize , respectively).

Truncation value for the prefiltered image pixels. The algorithm first computes x-derivative at each pixel and clips its value by [-preFilterCap, preFilterCap] interval. The result values are passed to the Birchfield-Tomasi pixel cost function.

Margin in percentage by which the best (minimum) computed cost function value should "win" the second best value to consider the found match correct. Normally, a value within the 5-15 range is good enough.
