Introduction

Jae Mook Choi is an inventor based in Daejeon, South Korea, associated with the Korea Advanced Institute of Science and Technology. His work includes an invention for measuring structural displacement by combining vision measurements with acceleration data.

Latest Patents

Choi is associated with 1 patent: “Method of Measuring Structure Displacement Based on Fusion of Asynchronous Vision Measurement Data of Natural Target and Acceleration Data of Structure, and System for the Same.” The patent describes calculating a scale factor that relates image pixels to real-world distance by combining camera images of a stationary target outside a structure with acceleration measurements collected on the structure. It then estimates structural displacement using feature-point matching and the calculated scale factor, despite the vision and acceleration data being sampled at different frequencies.

Career Highlights

Choi’s patented method addresses a practical challenge in structural monitoring: integrating asynchronous measurements from cameras and accelerometers to estimate displacement. The approach uses a natural target and combines visual information with motion data from sensors installed on the structure.

Collaborations

The provided information names Hoon Sohn and Zhanxiong Ma as Choi’s coworkers. Their specific roles in the patent or related research are not specified.

Conclusion

Jae Mook Choi’s patent presents a sensor-fusion approach to structural displacement measurement, combining camera imagery and acceleration data to support monitoring of structures.
