Overview

The aviation industry faces increasing pressure to enhance passenger safety, improve operational efficiency and meet stringent regulatory requirements while ensuring a seamless cabin experience. Our client, a leading aircraft manufacturer, recognized that traditional, manual monitoring methods were becoming a bottleneck. Traditional monitoring systems were limited in providing real-time insights into crew and passenger activity, posing challenges in both safety assurance and aircraft readiness.

To overcome these limitations, the client partnered with HCLTech to develop an AI-assisted aircraft cabin monitoring system. Designed with advanced computer vision and AI capabilities, this solution enables intelligent monitoring of multiple cabin scenarios, supporting pilots, cabin crew and ground staff through real-time alerts and predictive insights.

This case study examines the collaboration between HCLTech and the client in designing and deploying a state-of-the-art system. It also explores how the AI-assisted aircraft cabin monitoring system enables automated cabin awareness, encompassing intrusion detection, aisle obstruction monitoring to fatigue analysis and aircraft readiness checks, resulting in measurable improvements in efficiency, safety and cost savings.

The Challenge

The client faced a set of complex business challenges in managing cabin operations, such as:

Lack of real-time situational awareness: Manual monitoring of in-cabin scenarios, such as passenger movement, seat compliance and crew alertness, was inefficient and prone to error
Aircraft readiness checks: Ensuring cabins were secure and compliant before takeoff required faster and more reliable processes
Scattered data and limited analytics: Multiple camera feeds and monitoring systems operated in silos, preventing comprehensive visibility across the cabin
Hardware constraints: Any solution had to run efficiently on aviation-compliant hardware with limited compute availability

The manufacturer required an AI-enabled monitoring system that was accurate, real-time, resource-efficient and scalable across various aircraft models.

HCLTech’s Approach and Solution

HCLTech’s AI Engineering team collaborated with the client’s technical experts through a series of joint workshops and feasibility studies to identify and prioritize 12 high-impact use cases for real-time monitoring using computer vision.

To address the unique constraints of aircraft environments, we engineered a multi-modal system with custom model architectures built on Darknet and TensorFlow frameworks. Leveraged computer vision-based miniaturized deep learning models for multiple use case analysis. This system was optimized for aviation-grade hardware to ensure lightweight, high-speed performance.

Key highlights

Developed deep learning models tailored for multiple use cases, including face detection, aisle obstruction, pose detection and fatigue monitoring using Eye Aspect Ratio (EAR).
Implemented a modified feature translation approach to accurately detect occluded or truncated objects, ensuring reliable identification even in complex visual conditions.
Round robin scheduling of models to provide real-time analytics from multiple cameras.
Optimized video decoding and analytics to run on just 30% of available cabin hardware CPU capacity.
Integrated a unified interface for delivering fatigue alerts, readiness notifications and anomaly detection reports to cabin and ground crews.
Models were ported onto custom aviation hardware and validated through rigorous gate-based approval processes.
