Title: Innovations of Chang-Woo Chu

Introduction

Chang-Woo Chu is a prominent inventor based in Daejeon, South Korea. He has made significant contributions to the field of technology, particularly in the areas of 3D modeling and terrain information processing. With a total of 9 patents to his name, his work continues to influence advancements in electronics and telecommunications.

Latest Patents

One of his latest patents is a method and apparatus for matching 3-dimensional terrain information using heterogeneous altitude aerial images. This innovative method involves receiving a high-altitude numerical height model based on a terrain image captured at a specific high altitude. It also includes receiving 3D terrain information observed from a low altitude, which is generated from a terrain image captured at a lower altitude. The process generates a low-altitude numerical height model and measures the cross-correlation between the two models to calculate matching parameters. This allows for the adjustment of geospatial coordinates of the 3D terrain information, ultimately outputting georeferenced 3D terrain information in the same coordinate system as the high-altitude model.

Another notable patent is an apparatus for reconstructing a 3D model and the method for using it. This apparatus includes an image acquisition unit that captures multi-view images from multiple drones equipped with cameras. It also features a geometric calibration unit that estimates the motion variables of the drones based on the acquired images. The 3D model creation unit then reconstructs a 3D model of a dynamic object from the matched multi-view images using a multi-view stereo method.
