HDLGrabber() [1/2]

pcl::HDLGrabber::HDLGrabber	(	const std::string &	correctionsFile = `""`,
		const std::string &	pcapFile = `""`
	)

Constructor taking an optional path to an HDL corrections file.

The Grabber will listen on the default IP/port for data packets [192.168.3.255/2368]

Parameters

[in]	correctionsFile	Path to a file which contains the correction parameters for the HDL. This parameter is mandatory for the HDL-64, optional for the HDL-32
[in]	pcapFile	Path to a file which contains previously captured data packets. This parameter is optional

HDLGrabber() [2/2]

pcl::HDLGrabber::HDLGrabber	(	const boost::asio::ip::address &	ipAddress,
		const std::uint16_t	port,
		const std::string &	correctionsFile = `""`
	)

Constructor taking a specified IP/port and an optional path to an HDL corrections file.

Parameters

[in]	ipAddress	IP Address that should be used to listen for HDL packets
[in]	port	UDP Port that should be used to listen for HDL packets
[in]	correctionsFile	Path to a file which contains the correction parameters for the HDL. This field is mandatory for the HDL-64, optional for the HDL-32
