Loobo LB-108 AI-Powered Fixed Infrared Thermal Imaging Temperature Screening Gate

Overview

The Loobo LB-108 is a fixed-mount, AI-integrated infrared thermal imaging temperature screening gateway engineered for high-throughput, non-contact human temperature assessment in public access environments. It operates on the physical principle of passive long-wave infrared (LWIR) radiometry—detecting thermal radiation emitted by the human forehead within the 8–14 µm atmospheric transmission window—and converts raw pixel-level radiance data into calibrated temperature values using an embedded blackbody reference source and proprietary forehead-specific thermal mapping algorithms. Unlike clinical-grade thermometers, the LB-108 is designed for rapid epidemiological triage—not diagnostic evaluation—making it suitable for pre-screening applications where speed, scalability, and operational continuity are critical. Its architecture integrates a 160 × 120 uncooled microbolometer sensor with a synchronized 2-megapixel visible-light camera, enabling simultaneous thermal and visual data capture for intelligent region-of-interest (ROI) localization, facial detection, and ambient light-adaptive emissivity compensation.

Key Features

• Integrated high-stability blackbody source (20 mm × 30 mm aperture, ε = 0.96 ± 0.02) mounted directly adjacent to the IR sensor for real-time auto-calibration—eliminating drift caused by ambient thermal fluctuations.
• AI-driven forehead temperature algorithm that dynamically identifies and isolates the supraorbital region across varying pose angles, occlusions, and lighting conditions—rejecting background heat sources such as signage, windows, or HVAC vents.
• Embedded processing platform (Broadcom BCM2711 SoC) with dual Micro-HDMI outputs, dual-band Wi-Fi 802.11ac, and Gigabit Ethernet—enabling standalone operation without external PCs; display output supports 4K@60fps decoding via H.265/H.264.
• Thermal measurement accuracy of ±0.3 °C under controlled environmental conditions (20–30 °C ambient, <60% RH), with temperature resolution of 0.01 °C and thermal stability better than ±0.1 °C over 8-hour continuous operation.
• Ruggedized enclosure fabricated from flame-retardant, UV-stabilized PVC composite material—certified for IP54 ingress protection and rated for indoor deployment or outdoor use with optional weather-resistant canopy (operating range: 0 °C to 40 °C).
• Real-time throughput capacity of 150–200 individuals per minute at optimal standoff distance (2.5–4 m), with sub-50 ms per-person thermal acquisition latency and millisecond-scale facial ROI localization.

Sample Compatibility & Compliance

The LB-108 is intended exclusively for non-invasive, non-medical temperature screening of ambulatory individuals in controlled-access zones. It does not comply with IEC 60601-2-59 (medical infrared thermometers) or FDA 510(k) clearance requirements and is not authorized for clinical diagnosis, patient monitoring, or regulatory submission in GLP/GMP environments. However, its design adheres to foundational industrial standards relevant to thermal imaging system reliability and electromagnetic compatibility—including IEC 61000-6-3 (EMI emission limits) and IEC 61000-6-2 (immunity to electrostatic discharge, RF fields, and fast transients). The device supports audit-ready logging (timestamped thermal images, metadata, alarm events) and may be configured to export anonymized CSV or JSON records for integration with third-party health surveillance platforms compliant with ISO/IEC 27001 information security frameworks.

Software & Data Management

The LB-108 runs a purpose-built Linux-based firmware with an embedded web interface accessible via local network browser or mobile device. All thermal and visual data—including full-frame radiometric temperature matrices, annotated face thumbnails, and environmental context logs—are stored locally on microSD (up to 128 GB) or streamed in real time to cloud-hosted or on-premise servers via TLS 1.2–secured HTTP(S) POST or MQTT protocols. Alarm thresholds (e.g., ≥37.3 °C) are configurable per zone, with visual/audible alerts triggered only when both thermal and spatial validation criteria are met—reducing false positives from transient reflections or perspiration artifacts. Data exports include ISO 8601 timestamps, device serial number, ambient temperature/humidity (if external sensors are connected), and confidence scores for each detected face. While not FDA 21 CFR Part 11 compliant out-of-the-box, the system supports optional digital signature modules and role-based access control (RBAC) for organizations requiring ALCOA+ (Attributable, Legible, Contemporaneous, Original, Accurate) data integrity in regulated settings.

Applications

• Airport terminal entry points and immigration checkpoints for pre-boarding fever screening.
• Railway and bus station concourses managing passenger flow during peak travel periods.
• University campus gates and dormitory entrances supporting academic continuity planning.
• Hospital outpatient department vestibules serving as first-layer triage before clinical intake.
• Manufacturing plant access lanes ensuring occupational health compliance without disrupting line throughput.
• Shopping mall entrances integrating with visitor management systems for anonymized footfall analytics and thermal anomaly flagging.

FAQ

Is the LB-108 certified for medical use or clinical diagnostics?
No. It is a Class I non-medical screening device intended for preliminary thermal assessment only. It is not cleared by the FDA, CE-MDD, or NMPA for diagnostic purposes.
Does the system require regular calibration by a third-party lab?
No—its integrated blackbody enables autonomous recalibration every 2 minutes during operation. External verification against traceable NIST-calibrated sources is recommended annually for quality assurance programs.
Can the LB-108 operate reliably in direct sunlight or high-humidity outdoor environments?
It is rated for indoor use and sheltered outdoor deployment (e.g., covered walkways). For unsheltered outdoor sites, installation under a weatherproof canopy is mandatory to maintain thermal stability and optical clarity.
What data formats does the device support for integration with enterprise health platforms?
JSON and CSV exports containing timestamp, detected temperature, confidence score, image hash, and device metadata; RESTful API documentation and sample Python SDK are available upon request.
How is privacy handled when facial images are captured?
All visible-light images are processed onboard for ROI extraction only—the full frame is neither stored nor transmitted unless explicitly enabled via administrator-configured retention policies compliant with GDPR or CCPA requirements.
