Camera Rotational Vibration Correction Method for Vision Based Displacement Measurement Using Drone

In this study, instead of using the accelerometer inside the drone to correct the rotational vibration of the drone in displacement measurement using a drone, we propose a method for correcting the rotational vibration of a drone using a fixed point where the displacement inside the drone image does not occur. As a preliminary study for correcting the rotational vibration of a drone using a fixed point in the image, an experiment to measure the rotation angle by rotating the target after fixing the camera and measuring the displacement of a model structure where displacement occurs through a rotating camera Through an experiment, the accuracy of displacement measurement was verified when rotational vibration of the camera occurred. When the displacement is less than 3mm, the measurement reliability is low when camera vibration occurs, whereas when the displacement exceeds 3mm, it was measured relatively accurately.
