Multimodal SLAM is an important topic in 3D computer vision research. Recent visual-LiDAR SLAM systems use photometric error for camera pose estimation, but their use of sparse LiDAR projections underutilizes image information. Integrating 3D Gaussian Splatting allows full image rendering, but the e
Multi-camera systems are increasingly vital in the environmental perception of autonomous vehicles and robotics. Their physical configuration offers inherent fixed relative pose constraints that benefit Structure-from-Motion (SfM). However, traditional global SfM systems struggle with robustness due…
Scaled relative pose estimation i.e. estimating relative rotation and scaled relative translation between two images has always been a major challenge in global Structure-from-Motion (SfM). This difficulty arises because the two-view relative translation computed by traditional geometric vision meth…
Multiple sensors, especially cameras and LiDARs, are widely used in autonomous vehicles. In order to fuse data from different sensors accurately, precise calibrations are required, including camera intrinsic parameters, and relative poses between multiple cameras and LiDARs. However, most existing c…
Compared to widely used LiDAR-based mapping in autonomous driving field, image-based mapping method has the advantages of low cost, high resolution, and no need for complex calibration. However, the image-based 3D mapping depends heavily on the texture richness and always leaves holes and outliers i…
