Publication number: 20210201533Abstract: An information processing device includes an acquisition interface and a processor. The acquisition interface acquires a first detection image obtained by capturing an image of a plurality of target objects including a first target object and a second target object, which is more transparent to visible light than the first target object, using the visible light, and a second detection image obtained by capturing an image of the plurality of target objects using infrared light. The processor obtains a first feature amount based on the first detection image, obtains a second feature amount based on the second detection image, and calculates a third feature amount corresponding to a difference between the first feature amount and the second feature amount. The processor detects a position of the second target object in at least one of the first detection image and the second detection image, based on the third feature amount.Type: ApplicationFiled: February 25, 2021Publication date: July 1, 2021Applicants: OLYMPUS CORPORATION, THE UNIVERSITY OF TOKYOInventors: Atsuro Okazawa, Tomoyuki Takahata, Tatsuya Harada

Patent number: 10266097Abstract: When a vehicle body is on board an escalator, a control device makes an ejection determination by use of an external sensor. The control device makes an ejection determination by use of front-wheel rotation sensors. The control device makes an ejection determination by use of an inclination detecting unit. The control device switches a control mode from a boarding control mode to an ejection control mode, when at least one of the above three ejection determinations is affirmatively made.Type: GrantFiled: December 11, 2017Date of Patent: April 23, 2019Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, The University of TokyoInventors: Tomoyuki Takahata, Masaru Ishikawa, Yoshiyuki Senba, Takashi Izuo, Yusuke Kosaka
