Description
<p> UAV is attracting attention because it can be used to grasp the situation during disasters, create maps, and maintain structures. Generally, when creating 3D models using UAV aerial images, SfM/MVS software is used. However, images taken with UAV contain defocus images due to the effects of device shaking. Therefore, we need to manually remove defocus images from a large number of images. We focused on the fact that UAV aerial images are continuous images with a high wrap rate. In this research, we proposed a general-purpose method for extracting defocus images using the difference in edge rate between the previous and next images.</p>
