◆ appendSubImageVoxelsToPointCloud()

template<typename POINT_CLOUD_PTR_TYPE >
bool ml::PCLMLTools::appendSubImageVoxelsToPointCloud ( const SubImage &  subImg,
const ImageToPointCloudConversionParameters &  convParams,
POINT_CLOUD_PTR_TYPE  retPointCloudPtr 
)
inline

Creates a point cloud from an ML SubImage.

Parameters
subImgThe input SubImage whose voxels shall be thresholded and possibly added as points to retPointCloudPtr.
convParamsA container describing the parameters for the image to point cloud conversion.
retPointCloudPtrThe pointer is reset and set to the newly created point cloud.
Returns
true if all voxels have been added as points, false otherwise. This can be useful to set the isOrganized flag of the point set if this function was the only operation to add points to the point set.
