Additionally, we will discuss the pipeline builder and the unlocked goals of the OAK. So, let's dive in and explore the true potential of this device.

🤖 Understanding the OpenCV AI Kit (OAK)

The OpenCV AI Kit, also known as OAK, is a tiny yet powerful open-source spatial AI system. It can be best described as the offspring of an embedded 4K camera and a neural compute stick. The OAK comes in two variants, namely OAK-1 and OAK-D, each with its unique features.

🔬 Capabilities of the OpenCV AI Kit

The OAK-1 boasts of automatic motion-based lossless digital zooming. Its sensor has a higher resolution than the final display resolution of the image, allowing it to zoom in on areas with motion. On the other HAND, the OAK-D features stereo depth cameras that enable 3D object localization and object tracking in 3D space.

One of the key capabilities of the OpenCV AI Kit is Spatial AI. Spatial AI refers to the ability of an AI system to reason based on not just what it sees but also the distance and location of objects. The OAK, especially the OAK-D, utilizes its RGB camera and stereo camera for deep neural inference and depth estimation, enabling real-time Spatial AI.

🔌 Compatibility

The OpenCV AI Kit is compatible with various operating systems, including Windows, Ubuntu, Raspberry Pi, ROS2, and Jetson. It provides native support for Python, making it easy to get started with coding. Additionally, C++ is supported as the API is written in C++ with Python bindings using PyBind11. The Myriad X Visual Processing Unit (VPU) in the OAK provides immense computational capacity, making it a versatile choice for developers.

📐 Hardware Layout

The physical hardware of the OpenCV AI Kit is compact, with a size of approximately 65x36mm. It features a 12MP RGB camera sensor and a USB-C type connector for power and data transmission. The kit also includes buttons for reset and various peripherals such as UART, SPI, I2C, and GPIO pins.

📦 Out-of-the-Box Examples

One of the standout features of the OpenCV AI Kit is the wide range of out-of-the-box examples it provides. These examples cover various applications, including object detection, mask detection, face detection, vehicle and license plate detection, OCR, pedestrian detection with reidentification, pose estimation with 3D location, text detection with OCR, and semantic segmentation. These pre-built examples make it easy for developers to get started with the OAK and experiment with different functionalities.

🧩 Pipeline Builder

The OAK comes with a pipeline builder that allows users to visually build their image processing pipeline. Using the pipeline builder, developers can drag and drop blocks and customize parameters to create their desired applications. This feature greatly aids rapid prototyping and facilitates the development of custom AI applications using the OAK.

🔓 Unlocked Goals

The OpenCV AI Kit has several unlocked goals that further enhance its functionality. These milestones include the addition of an IMU (Inertial Measurement Unit) for image stabilization and motion-based deblurring, the introduction of a power over Ethernet variant, the option for aluminum/aluminum alloy casing, and the inclusion of Wi-Fi and Bluetooth versions. Additionally, reaching the final milestone unlocks a high-quality model suite, providing users with highly accurate and state-of-the-art models for their AI applications.

Conclusion

The OpenCV AI Kit (OAK) is a remarkable device that offers powerful spatial AI capabilities in a compact size. Its compatibility with multiple operating systems, versatile hardware layout, and the extensive range of out-of-the-box examples make it an ideal choice for developers and AI enthusiasts. With its pipeline builder, customizable parameters, and unlocked goals, the OAK provides immense flexibility and room for innovation. Whether you're a beginner or an experienced developer, the OpenCV AI Kit is worth exploring and integrating into your projects.
