Object detecting device and object detection method
An object detecting device and object detecting method, can be accurately detected object around the vehicle based on the sound information collected even in the case of generating an alarm sound.
Abstract
The present invention relates to an object detecting device and object detecting method, can be accurately detected object around the vehicle based on the sound information collected even in the case of generating an alarm sound. In the present invention, the sound collected by the sound collecting means (10) mounted on a vehicle, the frequency analysis by the frequency decomposition unit (21c) to collect the sound information, the sound information detected by the travel unit (21 d) based on the sound when the frequency characteristics of the detection object around the vehicle, so that in a case where a predetermined frequency characteristic is mounted in the reproducing apparatus (11) of the vehicle reproduced sound of the audio band pressure larger the predetermined object detection band ratio in the case of using a small predetermined frequency characteristics reproduced from the reproducing apparatus (11) in the sound pressure of the audio band object detecting predetermined frequency band suppressed.
