We propose a simple method called Multi-Scale Occ for occupancy prediction based on lift-splat-shoot framework, which introduces multi-scale image features for generating better multi-scale 3D voxel features with temporal fusion of multiple past frames. Post-processing including model ensemble, test-time augmentation, and class-wise thresh are adopted to further boost the final performance. As shown on the leaderboard, our proposed occupancy prediction method ranks the 4th place with 49.36 mIoU.","url_abs":"https://arxiv.org/abs/2306.11414v1","url_pdf":"https://arxiv.org/pdf/2306.11414v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[],"tasks":[{"task_slug":"prediction","task_name":"Prediction"},{"task_slug":"prediction-of-occupancy-grid-maps","task_name":"Prediction Of Occupancy Grid Maps"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[{"leaderboard":"/sota/prediction-of-occupancy-grid-maps-on-occ3d","task":"Prediction Of Occupancy Grid Maps","dataset":"Occ3D-nuScenes","model":"MiLO","rank_in_archive_order":3,"of":8,"metrics":{"mIoU":"52.45"},"uses_additional_data":false}],"syntology":{"atlas_url":"https://app.syntology.ai/?focus=2306.11414","mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
