Empowering Industries with Intelligent Object Detection and Proactive Decision-Making with Yolov5 and Raspberry Pi-powered reTerminal DM
Introduction
Object detection is a critical field in computer vision, encompassing tasks like identifying objects in images. This has practical applications in various sectors like surveillance, healthcare, and self-driving cars. Single-Stage Object Detectors are a subset of object detection models that directly predict object classes and bounding box coordinates without the need for an initial region proposal stage. This streamlines the process and is especially useful for real-time applications. One prominent example is the YOLO (You Only Look Once) family of models, known for their efficient single-stage approach to object detection, making them suitable for scenarios where speed is crucial without sacrificing accuracy.
YOLO
Revolutionizing the object detection domain, YOLO (You Only Look Once) marked a breakthrough by introducing the pioneering concept of treating object detection as a regression task within a single stage. This innovative approach involved a detection architecture that scrutinized the image just once to forecast both object positions and their corresponding class designations.
YOLOv5
The YOLOv5 series introduces a range of object detection architectures that come pre-trained on the MS COCO dataset. Following its launch, EfficientDet and YOLOv4 were subsequently introduced. Presently, YOLOv5 stands as an official state-of-the-art model, benefiting from extensive support and enhanced usability in production scenarios.
The notable aspect of YOLOv5 is its native implementation in PyTorch, which addresses the constraints of the Darknet framework. Darknet, built in C programming language, lacks a production-oriented perspective. While Darknet is valuable for research purposes, it has a smaller community and limited support.
The transition of YOLO to PyTorch simplifies architecture modification and enables seamless deployment across various environments. Additionally, YOLOv5 holds a place in the Torch Hub showcase as an official state-of-the-art model. This version’s PyTorch implementation eliminates the limitations posed by the Darknet framework, optimizing its applicability for production contexts.
YOLOv5n
The YOLOv5n and YOLOv5n6 models, known as Nano models, exhibit a substantial reduction of approximately 75% in parameters compared to their predecessors. The parameter count drops from 7.5 million to 1.9 million, rendering them suitable for deployment on mobile devices and CPUs. The visual representation also highlights that YOLOv5 exhibits notably superior performance compared to various versions of EfficientDet.
Notably, even the smallest iteration of YOLOv5, namely YOLOv5n6, achieves a comparable level of accuracy, surpassing EfficientDet in terms of speed. This observation underscores YOLOv5’s efficiency in delivering accurate results swiftly, making it a favorable choice, particularly in scenarios where performance and rapid processing are key considerations.
Demo
Before deploying a model on resource-constrained devices like Raspberry Pi, it’s often essential to perform model conversion and quantization to ensure optimal performance. This involves several steps to convert a PyTorch model (in .pt format) to a TensorFlow Lite (TFLite) model with quantization, specifically to uint8 data type.
Certainly, it’s worth noting that you have the flexibility to employ your custom dataset for training purposes. The reTerminal DM, powered by Raspberry Pi CM4, designed primarily for industrial applications, is adept at showcasing its capabilities through a practical demonstration. In this particular demonstration, the focus is on exemplifying object detection within the construction domain, specifically highlighting its efficacy in identifying Personal Protective Equipment (PPE) kits—a critical aspect of safety in this industry.
