return false;
if( depthGenerator.IsValid() )
depthGenerator.GetMetaData( depthMetaData );

}示例2: getCommonProperty
double CvCapture_OpenNI::getCommonProperty( int propIdx )
{
double propValue = 0;
switch( propIdx )
{
// There is a set of properties that correspond to depth generator by default
// (is they are pass without particular generator flag). Two reasons of this:
// 1) We can assume that depth generator is the main one for depth sensor.
// 2) In the initial vertions of OpenNI integration to OpenCV the value of
// flag CV_CAP_OPENNI_DEPTH_GENERATOR was 0 (it isn't zero now).
