Title: Innovations by Yuichi Ohshima

Introduction

Yuichi Ohshima is a notable inventor based in Kawasaki, Japan. He has made significant contributions to the field of defect detection technology, holding two patents that showcase his innovative approach to solving complex problems in structural analysis.

Latest Patents

Ohshima's latest patents include a defect detection apparatus and a calculation system. The defect detection apparatus features a defect detection unit and a calculation unit. The defect detection unit identifies defects on the external appearance of a structure through imaging processing, utilizing external appearance image data generated by a surveying instrument. The calculation unit then calculates defect data related to the identified defect using coordinate data correlated with the external appearance image data.

His second patent involves a calculation method and program that utilizes a target with a reference object of known size. This method detects the reference object from target image data, which is captured using a survey instrument. It calculates first size data on the dimensions of the reference object and compares it with second size data on the actual dimensions to derive correction data. This correction data is then used to adjust the defect data, enhancing the accuracy of the defect detection process.
