A Deep Dive into Video Annotation for Autonomous Mobility

February 20, 2024

The autonomous vehicle market is experiencing steady growth, with a projected global valuation of $2.3 trillion by 2030. Another study indicates that the rise of autonomous driving could create up to $400 billion in revenue by the year 2035.

Autonomous Vehicles (AVs), also known as self-driving vehicles, operate independently with minimal or no human intervention, encompassing a diverse range of vehicles such as cars, buses, and more, as long as all functions are automated. These cutting-edge vehicles can drive themselves and effortlessly navigate intricate roads, diverse locations, and dynamic environments.

Integration of autonomous vehicles into the transportation and mobility landscape is a game changer for the industry. As needed, these vehicles can assist or completely replace human drivers for enhanced transport efficiency and road safety. Key to their functionality is the heavy reliance on video annotation, enabling Autonomous Vehicles to interpret and respond to their surroundings with precision. 

Why Video Annotation is Crucial for Autonomous Vehicles

Imagine a self-driving car navigating complex traffic on a busy road, effortlessly identifying objects, and making safe decisions without human intervention. Autonomous vehicles require a massive amount of labeled video data to achieve it, and this is where the process of video annotation steps in.

Video annotation is a process in which objects, actions, or features within a video are labeled or annotated to provide additional information for machine learning algorithms. It involves marking and identifying specific elements in the video frames to enable the algorithm to recognize and understand different objects or activities.

Autonomous vehicles use cameras and sensors to capture real-time video footage of their surroundings. Video annotation helps identify and label objects such as pedestrians, cars, road signs, and traffic lights within these videos. By annotating the video frames with relevant information, AI/ML algorithms learn to recognize and interpret the visual data, enabling autonomous vehicles to make informed decisions and navigate safely in diverse environments.

The annotated video data is a vital part of the training dataset for machine learning models, allowing them to generalize patterns and make accurate predictions in real-world scenarios. 

Video Annotation Techniques for Autonomous Mobility

Here are some specific video annotation techniques in autonomous mobility:

Object Detection and Classification

Drawing bounding boxes around objects like pedestrians, vehicles, and obstacles facilitates accurate identification of their locations. Object classification entails assigning specific labels to various objects, enabling the Autonomous Vehicle to discern and differentiate between elements within its environment. 

Semantic Segmentation

This involves annotating each pixel in a frame individually to distinguish between various surfaces and objects, thereby contributing to a better comprehension of the layout of the surrounding environment.

Lane and Road Marking

This is about identifying and annotating road lanes, including lane boundaries and markings, to assist in autonomous navigation.

Traffic Sign Recognition

It includes labeling and classifying traffic signs to enable the autonomous vehicle to interpret and respond to regulatory and warning signs on the road.

Pedestrian and Cyclist Tracking

Tracking the movement of pedestrians and cyclists to ensure the Autonomous Vehicle can safely navigate around them.

Mapping and Localization

This involves integrating geospatial information into video frames to enhance mapping and localization accuracy for the autonomous vehicle.

Like these, there are various other video annotation techniques that collectively contribute to the development of comprehensive and diverse datasets that train machine learning models in the perception and decision-making processes of autonomous mobility systems. 

Choosing the Right Video Annotation Tool

Choosing the right video annotation tool is crucial for ensuring accurate and efficient annotation processes in the development of machine learning models. Consider the following factors when selecting a video annotation tool:

Annotation Capabilities

Evaluate the tool’s ability to support various annotation types, such as bounding boxes, semantic segmentation, and object tracking. Ensure it aligns with the specific requirements of your project. iMerit’s Video Annotation solution built on Ango Hub presents users with a timeline view showcasing annotations on the video. This functionality expands to frame-specific classifications, allowing annotators to classify individual frames within the video. Visualizing annotations throughout the entire video is facilitated, providing users with the capability to seamlessly add or delete keyframes, thereby enhancing their control over video annotations.

Ease of Use

Opt for an intuitive and user-friendly interface. The tool should streamline the annotation process, allowing annotators to work efficiently and minimize the learning curve.

Collaboration Features

Look for tools that facilitate collaboration among annotators. Features like real-time collaboration, annotation versioning, and commenting can enhance teamwork and communication.iMerit Video Annotation Solution supports real-time troubleshooting, where annotators can ask questions directly, which notifies project managers instantly.


Choose a tool that offers flexibility and customization. The ability to adapt annotation workflows, create custom labels, and tailor the tool to project-specific needs is essential.

Data Security and Privacy

Prioritize tools that prioritize data security and privacy. Ensure that the tool complies with relevant regulations and provides features such as encryption and access controls.


Consider the scalability of the tool, especially if your project involves large datasets. The tool should efficiently handle increasing annotation volumes without compromising performance.

Integration with Existing Workflows

Opt for a tool that seamlessly integrates with your existing workflows and platforms. Compatibility with popular machine learning frameworks and data management systems can simplify the overall development process. iMerit Ango Hub allows you to integrate diverse applications, solutions, or alternative MLOps platforms on the platform. 


Choose a partner that can scale your annotation efforts quickly, along with its solution capabilities. Human-in-the-loop (HITL) teams for video help enhance the accuracy and quality of annotated data for machine learning models. This team typically includes annotators, reviewers, and coordinators who work in collaboration with automated tools and algorithms.
