Title: Masatoshi Ohshima: Innovator in CCD Camera Technology
Introduction
Masatoshi Ohshima is a prominent inventor based in Aichi, Japan. He has made significant contributions to the field of imaging technology, particularly in the calibration of CCD cameras. With a total of three patents to his name, Ohshima's work has advanced the precision and functionality of three-dimensional measuring apparatuses.
Latest Patents
Ohshima's latest patents include a method of calibrating a CCD camera. This innovative method involves a series of sequential processes, including shifting a spotlight source held by a positioning device in front of a fixed CCD camera. The goal is to ensure that the light beam in the center of the light source can be incident upon a predetermined picture element of the solid sensor built into the CCD camera. The method also computes angles between multiple visual lines generated by shifting the light source and the optical axis of the CCD camera, allowing for precise calibration.
Another notable patent is for a three-dimensional measuring apparatus. This apparatus consists of at least a pair of CCD cameras that capture images of an objective surface requiring dimensional measurement. A laser scanner sequentially irradiates multiple spots on the measurable surface with laser beams, creating measuring points for the CCD cameras. The results of the dimensional measurement are directly displayed on the objective surface, and an image processing unit computes the actual dimensions based on the data received from the cameras.
