SJTU_GVI

A GNSS-Visual-IMU benchmark Dataset for SLAM

Project Authors: Jie Yin

This is part of the dataset for tests in paper M2C-GVIO Different from M2DGR, this dataset has following features:

1.More light-weight and easy for downloading.

2.Recoreded on a real car with high speed.

3.GNSS raw measurements are captured by a Ublox ZED-F9P receiver, which facilitate the GNSS-SLAM research.

Please give us a star if this project is helpful to your research. Thank you! If you use M2DGR in an academic work, please cite:
