DGT outperforms traditional methods by reducing computational cost and enhancing real-time performance.
Abstract
Multi-camera multi-target Tracking (MCMT) is often regarded as a downstream task of Multi-Object Tracking (MOT). Traditional methods typically follow an offline pipeline involving detection, re-identification, single-camera tracking, and post-hoc clustering, which leads to poor real-time performance, high computational cost, and weak adaptability in dynamic environments. Moreover, trackers tailored for specific locations overly rely on manually crafted information like road topology and camera calibration, reducing their effectiveness in varied scenarios. We propose Dynamic Global Tracking (DGT), an innovative online framework for Multi-Camera Multi-Target (MCMT) vehicle tracking. Unlike traditional methods that rely on full trajectory extraction and then clustering, the DGT integrates cross-camera associations directly into the tracking process. This transformation reduces the…
