About
Project: Computer Vision‐Based Structural Monitoring (COSMO)
Intelligent and automated inspection methods are receiving more and more attention with the long-term operation of many transportation infrastructures. Except for the continuous degradation of the material performance, human and natural loads (e.g. repeated loads from vehicles, wind and earthquakes) will result in cumulative or sudden damage to infrastructures, threatening safe operation and possibly leading to disasters.
Dr. Tengjiao Jiang focuses on developing inspection and evaluation methods for existing railways and bridges by using computer vision (CV) and deep learning (DL). The project is funded by the Norwegian Railway Directorate.

A 6-DOF camera motion correction method using IMU sensors for photogrammetry and optical measurements
This study proposed a novel 6-degree-of-freedom (DOF) camera shake correction method by using an inertial measurement unit (IMU) sensor to address the challenge of camera shake, caused by environmental conditions such as wind and ground traffic.
A visual inspection and diagnosis system for bridge rivets based on a convolutional neural network
The article studied fast inspection and diagnosis of bridge rivets based on a convolutional neural network (CNN) and drones. The rivet health conditions include normal (RN), rusted (RR), loose (RL) and missing (RM).
