Idea
A platform generating accurate online vectorized maps from camera data without costly HD map labels for autonomous vehicle developers.
Research Paper
Core Innovation
This paper presents PseudoMapTrainer, which eliminates the need for expensive ground-truth HD maps by generating pseudo-labels from unlabeled sensor data. It uses Gaussian splatting and 2D segmentation semantics to reconstruct road surfaces and introduces a mask-aware assignment and loss function for training. This enables semi-supervised pre-training on large-scale unlabeled crowdsourced data, improving scalability and reducing costs.

Research Paper Overview
PseudoMapTrainer: Learning Online Mapping without HD Maps
Summary
Online mapping models predict vectorized maps from multi-view camera images but rely on expensive ground-truth HD maps for training. PseudoMapTrainer generates pseudo-labels from unlabeled sensor data by reconstructing road surfaces using Gaussian splatting and 2D segmentation semantics. It introduces a mask-aware assignment and loss function to train without ground-truth maps and enables semi-supervised pre-training on large-scale unlabeled crowdsourced data.
