Object detection apparatus and an object detection method
The present invention aims to detect the sound information collected even if you generate an alarm sound objects around the vehicle with high accuracy by using a frequency decomposition unit and the frequency analysis.
Abstract
The present invention aims to detect the sound information collected even if you generate an alarm sound objects around the vehicle with high accuracy. To solve this problem, the present invention is collected by the sound collector 10 mounted on a vehicle, the collected sounds information in the frequency decomposition unit 21c and the frequency analysis, the in the running sound detection unit 21d when detecting for detecting an object around the vehicle based on the frequency characteristic of the sound information, the when the sound pressure in a predetermined frequency band is greater in the frequency characteristic of the sound reproduced from the reproducing apparatus 11 mounted on a vehicle the object detection using a predetermined frequency band, than object detection using the predetermined frequency band when the sound pressure in a predetermined frequency band is small in the frequency characteristic of the sound reproduced from the reproducing apparatus 11, is suppressed .
