The increasing urbanization and the growing number of vehicles in cities have underscored the need for efficient parking management systems. Traditional smart parking solutions often rely on sensors or cameras for occupancy detection, each with its limitations. Recent advancements in deep learning have introduced new YOLO models (YOLOv8, YOLOv9, YOLOv10, and YOLOv11), but these models have not been extensively evaluated in the context of smart parking systems, particularly when combined with Region of Interest (ROI) selection for object detection. Existing methods still rely on fixed polygonal ROI selections or simple pixel-based modifications, which limit flexibility and precision. This work introduces a novel approach that integrates Internet of Things, Edge Computing, and Deep Learning concepts, by using the latest YOLO models for vehicle detection. By exploring both edge and cloud computing, it was found that inference times on edge devices ranged from 1 to 92 seconds, depending on the hardware and model version. Additionally, a highly flexible pixel-wise post-processing ROI selection method is proposed for accurately identifying regions of interest to count vehicles in parking lot images, overcoming the limitations of conventional polygon-based approaches. The proposed system achieved 99.68% balanced accuracy on a custom dataset of 3484 images, providing a cost-effective smart parking solution that ensures precise vehicle detection while preserving data privacy, improving upon the previously used method by over 20 percentage points while maintaining the inference at the edge.
