About

HyperVariables comprises low-level containers used in HyperSLAM to represent parameters within non-linear optimizations. All implemented variables are fully interoperable with Eigen and, as such, are mappable from raw memory locations. All variables inherit from an abstract base, which allows storing non-homogeneous variables in a simple and unified manner. At present, three different distortion models along with two common Lie groups and other common variables are implemented. Where adequate, we also provide analytic Jacobians for the implemented operations. If you use this repository, please cite it as below.

Note: Development on HyperSLAM-related repositories has been discontinued.

Installation

HyperVariables depends on the Eigen, Google Logging and Google Test libraries and uses features from the C++20 standard (see link to update gcc and g++ alternatives). The setup process itself (without additional compile flags) is as follows:

```

Clone repository.

git clone https://github.com/VIS4ROB-lab/HyperVariables.git && cd HyperVariables/

Run installation.

chmod +x install.sh sudo install.sh

Build repository.

mkdir build && cd build cmake .. make ```

Known Issues

  1. Tests covering the (equidistant) distortion models occasionally fail due to surpassing the numeric tolerances.
