Our work SNAIL Radar Benchmark for Radar-based SLAM accepted by IJRR. Thanks to my collaborators!

IMO, this paper presents the first SLAM dataset with ground truth assessment. It also features a lidar inertial localization method based on forward backward smoothing, and rigour sensor synchronization and calibration schemes.

Our work A Low-Cost Portable Lidar-based Mobile Mapping System on an Android Smartphone accepted by ISPRS GSW2025

IMO, this paper presents the first lidar-camera portable mapping system on an Android phone. We did thorough calibration, synchronization, and mapping tests. The prototype is shown at here.

Our work 4D RadarPR: Context-Aware 4D Radar Place Recognition in Harsh Scenarios accepted by ISPRS JP&RS. Great work by Yiwen.

IMO, this paper presents an attention-based feature fusion method to get deep descriptors for 4D radar place recognition, tested on both TI short range radars and SNAIL radar dataset.

Our paper on geometric camera calibration published on Sensors Journal

A comprehensive survey effort including a variety of simulation and real data tests, revealing camera calibration limits.

CVPR 2023 Photogrammetric Computer Vision Workshop accepting papers by Mar 6 2023

Thanks to my fabulous collaborators, we are honored to hold a workshop in CVPR 2023 on photogrammetry and computer vision. For more info, please consult here. The deadline to submit a paper to the workshop is Mar 6 2023. Accepted papers by the workshop will be included in the CVPR2023 proceedings :).

Our paper on rolling shutter calibration with an LED panel published on Optics Letters

With three months of hard work, our work surfaces on Optics Letters. The idea is to calibrate the rolling shutter effect by making use of the same duration principle, regardless of camera misalignment and lens distortion.
