Module ltp

Local Tangent Plane (LTP) and local cartesian coordinates.

See Also: Local tangent plane coordinates and class LocalCartesian, transcoded from Charles Karney's C++ classLocalCartesian.

Version: 26.07.24

Classes

Attitude
The pose of a plane or camera in space.

AttitudeError
An Attitude or Attitude4Tuple issue.

Frustum
A rectangular pyramid, typically representing a camera's field-of-view (fov) and the intersection with (or projection to) a local tangent plane.

LocalError
A LocalCartesian or Ltp related issue.

LocalCartesian
Conversion between geodetic (lat, lon, height) and local cartesian (x, y, z) coordinates with geodetic origin (lat0, lon0, height0), transcoded from Karney's C++ class LocalCartesian.

Ltp
A local tangent plan (LTP), a sub-class of LocalCartesian with (re-)configurable ECEF converter.

LqRD
A local tangent plan (LTP) for conversion between GRS80 (ETRS89) geodetic and local Netherlands' quasi-RijksDriehoeksmeting (RD) coordinates.

Functions

tyr3d(tilt=0, yaw=0, roll=0, Vector=<class 'pygeodesy.vector3d.Vector3d'>, **name_Vector_kwds)
Convert an attitude pose into a (3-D) direction vector.

Variables

__all__ = _ALL_LAZY.ltp

Function Details

tyr3d (tilt=0, yaw=0, roll=0, Vector=<class 'pygeodesy.vector3d.Vector3d'>, **name_Vector_kwds)

Convert an attitude pose into a (3-D) direction vector.

Arguments:

tilt - Pitch, elevation from horizontal (degrees), negative down (clockwise rotation along and around the x-axis).
yaw - Bearing, heading (compass degrees360), clockwise from North (counter-clockwise rotation along and around the z-axis).
roll - Roll, bank (degrees), positive to the right and down (clockwise rotation along and around the y-axis).
Vector - Class to return the direction vector (Cartesian, Vector3d or Vector3Tuple) or None.
name_Vector_kwds - Optional name=NN (str) and optionally, additional Vector keyword arguments, ignored if Vector is None.

Returns:

A named Vector instance or if Vector is None, a named Vector3Tuple(x, y, z).

Raises:

AttitudeError - Invalid tilt, yaw or roll.
TypeError - Invalid Vector or name_Vector_kwds.
