◆ openDeviceBySerial()

unsigned int COpenNI2Generic::openDeviceBySerial ( const unsigned int SerialRequired )

Open a RGBD device specified by its serial number.

This method is a wrapper for openDevicesBySerialNum(const std::set<unsigned>& vSerialRequired) This method requires to open the sensors which are still closed to read their serial.

◆ openDevicesBySerialNum()

unsigned int COpenNI2Generic::openDevicesBySerialNum ( const std::set< unsigned > & vSerialRequired )

Open a set of RGBD devices specified by their serial number.

Raises an exception when the demanded serial numbers are not among the connected devices. This function also fills a vector with the serial numbers of the connected OpenNI2 sensors (this requires openning the sensors which are still closed to read their serial)
