📷 Introduction

Welcome to this comprehensive guide on the OpenCV AI Kit, OAK-D-Lite. This article will provide you with detailed insights into this innovative camera and its functionalities, allowing you to make informed decisions for your AI-based projects.

📷 OAK-D-Lite: An Overview

The OAK-D-Lite is a state-of-the-art camera designed specifically for AI-based projects. Developed by OpenCV AI Kit, this device offers a wide range of features and capabilities to enhance the effectiveness of your projects. In comparison to its predecessor, the OAK-D, the OAK-D-Lite is a more affordable option, making it accessible to a larger audience.

📷 OAK-D-Lite vs. OAK-D: What Has Changed?

The primary difference between the OAK-D-Lite and its higher-priced counterpart, the OAK-D, is the price point. The OAK-D-Lite is available for $84, while the OAK-D comes with a price tag of $199. This significant price decrease has sparked Curiosity among users, leading them to wonder what changes have occurred in the OAK-D-Lite version.

📷 Understanding the Camera Features

The OAK-D-Lite boasts an impressive array of camera features. It consists of three lenses, with a Sony IMX214 Image Sensor at the center, capable of capturing high-quality 4K RGB images. The type of lens can be chosen at the time of purchase, determining whether the camera has a Fixed Focus or Auto Focus capability.

Lens Options and Autofocus

For projects that involve shaky images or require RGB depth alignment, the Fixed Focus lens is an ideal choice. However, if the project requires spotting objects at close range, the Auto Focus lens provides a better solution.

Resolution Differences and OV7251

It is important to note that the resolution of the lenses has been lowered from 1280x800 to 640x480 in the OAK-D-Lite. This change is attributed to the utilization of the OV7251 camera module, which can capture black and white images at 120FPS with VGA resolution.

Lack of IMU and External Power Jack

One limitation of the OAK-D-Lite is the absence of an IMU (inertial measurement unit). Consequently, it does not provide information about the camera's rotation and movement in space. Additionally, the device lacks an external power jack, relying solely on the USB-C port for both data transfer and power delivery. This may cause issues when used with devices like the Raspberry Pi, which may have insufficient power supply.

📷 Choosing OAK-D-Lite for Your Project

If you are undecided about which camera to choose for your project, the OAK-D-Lite presents itself as a compelling option. Its affordability and impressive features make it an excellent starting point. By exploring the source code and the limited parts provided with the OAK-D-Lite, you can ascertain the specific products needed to accomplish your project goals effectively.

📷 Getting Started with DepthAI SDK

To leverage the full potential of the OAK-D-Lite, it is essential to familiarize yourself with the DepthAI SDK. This software development kit offers Python and C++ APIs, enabling seamless integration of the camera into your project. Furthermore, the SDK provides well-documented resources, making it effortless to get started with the OAK-D-Lite.

DepthAI SDK and Available APIs

The DepthAI SDK serves as the default framework for utilizing the OAK-D-Lite's capabilities. It offers a range of APIs that cater to various development requirements. Whether you are a Python enthusiast or prefer working with C++, the SDK provides the necessary resources to kickstart your project.

Well-Organized Documentation

One of the standout features of the DepthAI SDK is its comprehensive and well-organized documentation. This ensures that developers, regardless of their experience level, can easily navigate the resources and find the necessary information to utilize the OAK-D-Lite effectively.
