Title:
"3D reconstruction of thunderstorm cloud top using airborne monocular camera”

Abstract:
"Typhoons are natural disasters which cause deaths and damaged properties to several countries. Consequently, it is important to analyze this meteorological phenomenon to allow researchers to understand its behavior, and properly deal with the hazards that go with it. A standard mode of visualization of typhoons involves the use of three-dimensional representations of a typhoon cloud top. This helps meteorologists estimate some of the typhoon’s parameters. Creating a three-dimensional model requires visible distinct features or landmarks in the cloud’s stereo images. This is difficult as clouds does not normally have rigid structures like points and corners to serve as landmarks. In this study, a 3D structure of Typhoon Trami’s cloud top was reconstructed using aircraft images taken on September 26, 2018. Aircraft images provide closer views of the typhoon cloud top than that of satellite images. Aircraft imaging allows for the manual adjustment of the camera to capture images ideal for 3D reconstructions. A commercially available software was used to process the 3D reconstruction of Typhoon Trami’s cloud top. This software allows automated selection of stereo correspondences that can be guided by manual selection of reference points in the images. From the result, an estimate of the cloud top dimension can be derived."
