Publication number: 20210350706Abstract: A sensing device senses an object present in a blind spot in the surrounding environment of a moving body. The sensing device is provided with a detection unit, a distance measurement unit, and a control unit. The detection unit radiates a physical signal from the moving body to the surrounding environment, and detects a reflection signal which is a reflection of the radiated physical signal. The distance measurement unit detects distance information indicating the distance from the moving body to the surrounding environment. The control unit analyzes the result of the detection by the detection unit. The control unit: senses, on the basis of the distance information, a blind spot region indicating a blind spot in the surrounding environment, and another moving body travelling in front of the moving body towards the blind spot region; and senses an object in the blind spot region on the basis of a reflected signal reflected by the other moving body, in the result of the detection by the detection unit.Type: ApplicationFiled: March 12, 2019Publication date: November 11, 2021Inventors: Naoki YOSHITAKE, Keiki MATSUURA, Yoshitaka TSURUKAME
