A Robust Online Multi-Camera People Tracking System with Geometric Consistency and State-aware Re-ID Correction
Computer Vision and Pattern Recognition（2024）
Shanghai Jiao Tong University
Abstract
Multi-camera multiple people tracking is a crucial technology for surveillance, crowd management, and social behavior analysis, enabling large-scale monitoring and comprehensive understanding of complex scenarios involving multiple individuals across different camera views. However, due to severe occlusion within the scene and significant variations in camera viewpoints, there are high demands for matching and correlating the same target among different cameras, especially in an online setting. To address this challenge, we propose a novel online multi-camera multiple people tracking system. This system integrates geometric-consistent constraints and appearance information of the targets, effectively improving tracking accuracy. Additionally, we design a state-aware Re-ID correction mechanism that adaptively leverages Re-ID features to correct mismatches among targets. This system has demonstrated good adaptability across various scenarios. Our proposed system is evaluated in track1 of the 2024 AI City Challenge [38], achieving a HOTA score of 67.2175% and securing the 2nd position on the leaderboard. The code will be available at: https://github.com/ZhenyuX1E/PoseTrack.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
