Vision AI for Advanced People Screening
Intel RealSense depth cameras power advanced security solutions for airport screening, loss prevention, customs and border control, and venue security.
Challenge
Security teams at airports, entertainment venues, distribution centers, and many other high-traffic areas need a safe and efficient way to deter theft and ensure that people don’t bring prohibited items into public areas.
Solution
Thruvision’s people-screening technology can detect items hidden under clothing by measuring the thermal energy emitted by the human body. Intel RealSense Depth Camera D435 captures optical images and depth information about objects in the scene, over which a THz (thermal) image is overlaid.
Results
Thruvision removes the need for physical “pat-downs” and other types of close proximity searches such as walk-through metal detectors and body scanners, allowing security officers to efficiently screen people from a safe distance.
The Need for Effective, Discreet, High-throughput Screening
Thruvision, a leader in people-screening technology, offers advanced detection solutions utilized in diverse settings such as airports, border crossings, retail environments, distribution centers, and public venues. Utilizing patented passive terahertz (THz) imaging technology, Thruvision systems can detect both metallic and non-metallic items hidden under clothing by measuring the thermal energy emitted by the human body. Concealed items block this body energy, allowing Thruvision sensors to identify them instantly.
How it works
Thruvision integrates Intel RealSense Depth Camera D435 to capture optical images and depth information. This data is processed with terahertz signals through sensor fusion, providing precise 3D information for accurate detection.
An intelligent AI machine vision platform
Thruvision uses AI algorithms to remove background distractions, enhancing focus on screening tasks. Depth information from Intel RealSense cameras bridges the optical and terahertz imaging domains, increasing detection accuracy and operator productivity.
Enhanced focus and privacy
By removing distractions and irrelevant background elements, operators can concentrate on monitoring individuals passing through the screening lane. Additionally, privacy is preserved by blurring the faces of screened individuals. Thruvision’s SmartFocus technology, using depth information and AI algorithms, defines the outline of the person being screened and treats all other elements as removable background.
Simplified Integration with Intel RealSense SDK
The Intel RealSense SDK offers ready-to-use APIs for aligning depth and color data, simplifying the software development process with necessary tools and libraries. Intel’s “field-ready” packaging eases the mechanical integration into Thruvision’s products and system deployment by eliminating the need to design and construct customized screening environments.
