Motion-Blur Compensation Method Using a Transparent Hexagonal Prism

Although the use of a traveling monitoring system to inspect infrastructure structures improves efficiency, there are concerns about image quality degradation and inspection accuracy due to motion blur caused by movement. Therefore, this research aims to develop a method to rotate a transparent acrylic hexagonal prism and control the optical axis in accor- dance with Snell’s law to capture images while compensating for the motion in real time. In the previous study, the same incident angle was visited only every quarter of a rotation because a cube was used, and the overlap region was not included in the continuous image in an optical system with a narrow angle of view. Experiments have confirmed that it is possible to capture continuous images of a moving object in a similar shape at a maximum speed equivalent to 70 km/h, while compensating for motion blur of the object without interruption.
