Member Function Documentation

Init()

bool fpsdk::common::trafo::Transformer::Init	(	const std::string &	source_crs,
		const std::string &	target_crs )

Initialise transformer.

The source and target CRS specification can be anything that proj_create_crs_to_crs() understands (see https://proj.org/en/9.4/development/reference/functions.html#c.proj_create_crs_to_crs). You may have to change the PROJ configuration (proj.ini) and/or update some PROJ data yourself to support some CRS. See the PROJ documentation for details (see https://proj.org/en/9.4/resource_files.html).

Parameters

[in]	source_crs	Source coordinate reference system, e.g. "EPSG:4326"
[in]	target_crs	Target coordinate reference system, e.g. "EPSG:2056"

Returns

true on success, false otherwise (bad params, missing data, ...)

Transform() [1/3]

bool fpsdk::common::trafo::Transformer::Transform	(	Eigen::Vector3d &	inout,
		const bool	inv = false )

Transform coordinates.

Parameters

[in,out]	inout	Coordinates to transform, replaced with result
[in]	inv	Do the inverse transformation (true), default is forward (false)

Returns

true on success, false otherwise

Transform() [2/3]

bool fpsdk::common::trafo::Transformer::Transform	(	const Eigen::Vector3d &	in,
		Eigen::Vector3d &	out,
		const bool	inv = false )

Transform coordinates.

Parameters

[in]	in	Coordinates to transform
[out]	out	Transformed coordinates
[in]	inv	Do the inverse transformation (true), default is forward (false)

Returns

true on success, false otherwise

Transform() [3/3]

bool fpsdk::common::trafo::Transformer::Transform	(	const Eigen::Vector4d &	in,
		Eigen::Vector4d &	out,
		const bool	inv = false )

Transform coordinates (with time).

Parameters

[in]	in	Coordinates to transform (with time)
[out]	out	Transformed coordinates (with time)
[in]	inv	Do the inverse transformation (true), default is forward (false)

Returns

true on success, false otherwise
