Title:
障害物検知装置
Document Type and Number:
Japanese Patent JP7101896
Kind Code:
B2
Abstract:
An obstacle detection device (100) comprises: a distance measurement sensor (110) for transmitting and receiving a signal wave having a frequency lower than or equal to a predetermined frequency; a window setting unit (150) for setting, as a window, a range in which a reception signal exhibited by a reception wave received by the distance measurement sensor (110) falls; a correlation calculation unit (160) for acquiring a correlation waveform by subjecting the reception signal in the window set by the window setting unit (150) to correlation calculation using a transmission signal exhibited by a transmission wave transmitted by the distance measurement sensor (110); a determination unit (170) for determining that a person is present as an obstacle if there are a plurality of peaks in the correlation waveform acquired by the correlation calculation unit (160); and an output unit (190) for outputting determination information indicating the result of the determination by the determination unit (170).
