City Scale Multi Camera Vehicle Tracking Using Deep Learning

Abstract

Intelligent city and traffic management depend on city-scale multi-camera vehicle tracking; however, this work has various difficulties. On the different viewing angles, problems arise that include the variation on the large scale, frequent occlusion and appearance variation. In this study, we use the cross-camera tracking technique and multi-camera tracking system that considers aggregation loss. To address the challenges of multi-camera vehicle tracking, the suggested system has four key parts. First, we extract the tracks with the help of a single camera view by identifying the object and multi-object tracking modules. These modules combine their detection capabilities to provide efficient tracking between frames. After obtaining the tracklets, we use a multi camera re-identification module to match them. The tracklets acquired by several cameras are connected by this module using re-identification techniques. We used OsNetX1_0 and retinaNet50 for reidentification. In the final stage, we deal with the isolated trackless and tracking of the synchronize ids that rely on the outcomes of the re-identification. We improve the computational performance with the help of less parameter models and cohesion of the tracking system by removing isolated tracklets and assuring consistent tracking IDs. With practical and effective alternatives, the research advances multi-camera vehicle tracking on the city scale. However, this system shows the significance of the fast-multi-target cross-camera tracking approaches and the loss of aggregation in the study challenges. The AI city challenges' success reveals our system's potency and viability.
