US 2026/0276438 A1 · High-Definition Distributed Fiber Optic Sensing (HD-DFOS) for Smart Intersection and Road Conditions Diagnostics

Abstract

A high-definition distributed fiber optic sensing (HD-DFOS) system and method for traffic monitoring and road condition diagnostics. The system utilizes optical fibers deployed along roadsides to capture high-temporal-resolution vibrational signals, capturing thousands of frames per second to clearly identify ground vibration wavefronts. A high-performance, multi-process computational platform utilizing shared memory converts 16-bit multi-channel transient traces into pseudo-color RGB images. A “You Only Look Once” (YOLO) object detection model is applied to the pseudo-color images to classify the sources of mechanical disturbances, distinguishing between vehicle-induced vibrations, ambient ground disturbances, and impacts with surface defects like potholes or cracks in real-time

Dependent claims

A high-definition distributed fiber optic sensing (HD-DFOS) system for smart intersection traffic monitoring and diagnostics, comprising:

an optical fiber deployed along a roadway;
an interrogator coupled to the optical fiber configured to capture vibrational signals at a temporal resolution of at least one thousand frames per second;
a computational platform configured to receive data streaming from the interrogator, wherein the computational platform converts 16-bit digitized, multi-channel transient traces from the vibrational signals into 2D pseudo-color RGB images;
and
a YOLO (You Only Look Once) object detection model trained on cropped patterns from the pseudo-color RGB images to classify the source of mechanical disturbances in real-time.
