Title: Innovations by Yu Jin Jang

Introduction

Yu Jin Jang is a prominent inventor based in Gyeongju-si, South Korea. She has made significant contributions to the field of 3D shape extraction technology, particularly in relation to metal surfaces. With a total of 2 patents, her work showcases her expertise and innovative spirit.

Latest Patents

One of her latest patents is titled "Method and system for reliable 3D shape extraction of metal surface." This invention involves a method where images are acquired simultaneously by irradiating interference-free polarized lights onto a metal object. A photometric stereo method is then applied to the images, excluding those that may lead to inaccuracies in 3D shape extraction.

Another notable patent is "System and method for extracting a 3D shape of a hot metal surface." This system includes a light source unit that emits four types of light, with two types having different wave bandwidths from the hot target object. The image acquisition unit captures 2D images of the target object using these polarized lights, while the image processing unit employs a photometric stereo technique to extract the 3D shape of the surface.
