Basalt Headers
Documentation for Basalt Headers

This is documentation page for the reusable components of the Basalt project extracted as header-only library.

Repository URL: https://gitlab.com/VladyslavUsenko/basalt-headers

This library includes:

  • Camera models.
  • Standalone image datatype with support for views, interpolation, gradients, and image pyramids.
  • Uniform B-Splines for Rd (d-dimentional vectors), SO(3) and SE(3).
  • Preintegration of inertial measurement unit (IMU) data.
  • Data types to store IMU-camera calibration.
  • Cereal serialization for basalt types as well as some Eigen and Sophus types.
