Researchers have developed AutoCompass, a new method for training neural map matchers that can accurately determine an image's pose relative to a 2D map, even when the training data contains noisy labels. The approach demonstrates that explicit heading labels are not required, as models can learn to predict accurate headings from raw GPS data alone. By incorporating a tolerance region around GPS coordinates and utilizing relative poses from Simultaneous Localization and Mapping (SLAM) or Structure from Motion (SfM) when available, AutoCompass achieves superior performance on driving and egocentric benchmarks compared to traditional methods relying on precise absolute pose labels.
