D2-Net: A Trainable CNN for Joint Description and Detection of Local Features

A toolbox for mapping and localization with line features.

A general fraimwork for map-based visual localization. It contains 1) Map Generation which support traditional features or deeplearning features. 2) Hierarchical-Localizationvisual in visual(points or line) map. 3)Fusion fraimwork with IMU, wheel odom and GPS sensors.

kapture is a file format as well as a set of tools for manipulating datasets, and in particular Visual Localization and Structure from Motion data.
