Enhancing Object Detection with FPGA Technology: Improving Speed and Efficiency Over Traditional Methods
Challenge
In today’s rapidly advancing world, remarkable technological advancements are happening every minute in every field. One area that has experienced a massive transformation is the convergence of Embedded systems, the Internet of Things (IoT), and cutting-edge technologies such as Artificial Intelligence (AI), Machine Learning (ML), and computer vision. These advancements have led to significant progress in the field of image detection, with object detection emerging as one of the most successful breakthroughs in computer vision. When it comes to implementing image detection, experts often debate the effectiveness of using AI-Python models versus Field Programmable Gate Arrays (FPGAs). Both AI-Python models and FPGAs possess unique strengths and can be highly effective in different scenarios. Recognizing the value of exploring different approaches, our embedded team embarked on a Proof of Concept (PoC) journey. The goal of this project was to explore how real-time object detection using FPGA utilized to enhance object detection by improving speed and efficiency in comparison to traditional methods that is using AI-based Python models. The primary objective of our PoC was to implement the Single Shot Detector (SSD) model on an FPGA and compare the results obtained with running the same model on a CPU. By focusing on the implementation of real-time object detection using FPGA, our team aimed to harness the power of FPGAs to enhance real-time vision systems. This would enable us to facilitate rapid and precise object detection in a wide range of applications. FPGAs offer the potential for high parallelism, low latency, and real-time processing, making them well-suited for computationally intensive tasks like object detection. By leveraging the capabilities of FPGAs, we aimed to overcome some of the limitations associated with AI-python models. Additionally, FPGAs can be customized and optimized for specific algorithms, resulting in improved efficiency and performance compared to general-purpose CPUs.

Solution
Our implementation of real-time image processing with FPGA utilizes the SSD MobileNet model, chosen for its compact size, speed, and good accuracy. The ZCU-104 development board from Xilinx was selected for its abundant resources and built-in ports like Ethernet, DisplayPort, micro USB, and USB. We deployed the SSD model, an evolution of the VGG-16, by adding convolutional layers for classification. To optimize the model for FPGA execution, we used Vitis AI, a Xilinx development platform, to quantize the original 32-bit model to an 8-bit version without compromising accuracy. Further optimization was achieved through pruning, removing unnecessary neural connections, and fine-tuning training parameters. The optimized model was compiled into an X model file, containing the instruction set for the Deep Learning Processing Unit (DPU) IP.
