Title: Innovations of Inventor Hideki Shirai

Introduction

Hideki Shirai is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of object detection and radar technology. With a total of five patents to his name, Shirai's work showcases his expertise and innovative spirit.

Latest Patents

Among his latest patents are an object detection device, an object detection method, and a computer-readable recording medium. The object detection device is designed to acquire multiple images captured by a camera mounted on a moving body, along with the movement information of the camera. It extracts edges from the first image and calculates candidate points in a second image based on the movement information. The device then calculates a correlation index value between the edge and each candidate point, detecting the point with the largest correlation as the correspondence point of the edge. This technology allows for the detection of objects at the edge position when the correlation index value meets a predetermined threshold.

Another notable patent is a FMCW-type radar device. This device generates snapshot data from a beat signal that represents the radar's received condition during each modulation period. It averages auto-correlation matrices generated from the snapshot data and calculates the target azimuth of objects, such as preceding vehicles, using the MUSIC (MUltiple SIgnal Classification) method. The radar device employs a weighting average based on the amount of mixed noise contained in the snapshot data, enhancing its accuracy in detecting targets.
