How Computer Vision Can Help Airports Manage Travel Volume

By Sanjay Bhakta Head of Solutions

It’s going to be a long summer for the air travel industry. The good news is that the air travel industry, battered by the economic effects of the COVID-19 pandemic, is recovering as demand for flights surges. Over two million people traveled by plane each day on average between April 17 and 23, according to the Transportation Security Administration; that figure averaged about 2.4 million in 2019. The bad news? The air travel industry is ill equipped to manage the demand because of a chronic labor shortage in airports and airlines. There are already reports of airports facing massive delays processing passengers, and airlines trimming routes to avoid meltdowns. These problems also present an opportunity for airports and airlines to use technology more strategically. One example: computer vision.

What Is Computer Vision?

Computer vision is a form of artificial intelligence (AI) that allows computers to analyze visual data such as pictures and video and make intelligent decisions based on that analysis. Computer  vision  encompasses  modeling  and  reproducing  human  vision  by using software and hardware to reconstruct, translate, and comprehend videos and   images. Computer  vision  applications  consists of  five categories: image classification, object detection, image similarity, image segmentation, keypoint detection, and object detection. For example, Autonomous  vehicles require computer vision to detect objects, lane markings, signs, and traffic signals to drive safely.  Retailers use computer vision to keep stores secure.

How Computer Vision Can Help Airports

Computer vision can also help airports manage customer service and security especially with fewer people. Here are two applications:

  • Passenger experience: We all know how exasperating it can be to stand in long lines at security checkpoints and gates. Unfortunately, this reality is likely to be part of air travel for the foreseeable future. Cameras equipped with computer vision can improve line management by proactively determining when to add customer service personnel to an airport check-in counter or to open another security line. And an airport can more proactively manage the passenger experience by correlating computer vision with passenger data to verify a person’s identity and then authorizing passengers who qualify for pre-check without human intervention.
  • Baggage  handling:  Computer  vision  cameras  and  sensors  can  make  passenger  baggage  inspections  more  accurate.  Unsafe  and  prohibited  belongings  have  less  of a chance of slipping through monitors because smarter cameras can detect and flag more minute, harder-to-find objects.

So, why haven’t airports used computer vision as extensively as they could? Well, the technology has needed time to advance. In  the  past,  cameras  powered  by  computer  vision  required  extensive  coding  and  debugging  to  develop  and  implement  reliably.  But  deep  learning  technology  has  achieved a breakthrough. Deep  learning  technology  uses  neural  networks  to  teach  computers  to  learn  by  example.  With  deep  learning  technology,  a  camera  powered  by  computer  vision  can  teach itself to identify objects more accurately and not confuse them with other objects – understanding, for instance, the difference between a carabiner and a carabiner that contains a fold-out knife.

But deep learning doesn’t happen by itself. The AI needs to be trained to know what to look for. And tested. And validated. Just the training challenge alone can seem mind-boggling. Human beings must train AI to understand all the forms of baggage that exist. People  need  to  generate  the  images  manually  and,  from  there,  label  them  correctly  and  upload  them  into  a  central  repository.  With  humans  in  the  loop,  active  learning  accelerates the generation of images, labeling, and data.
