US 2021/0055705 A1 · ABNORMAL-SOUND DETECTION DEVICE AND ABNORMAL-SOUND DETECTION METHOD

Abstract

[Problem] To provide an abnormal-sound detection device in which incorrect detection is rare. [Solution] An abnormal-sound detection device has an imaging means, an operation range identification means, a sound collection means, an abnormal-sound detection means, an abnormal-sound generation position identification means, and an abnormal-sound source determination means. The imaging means captures an image of a diagnosis object. The operation range identification means identifies and stores the operation range of the diagnosis object on the basis of the image captured by the imaging means. The sound collection means collects sounds arriving from the diagnosis object and the vicinity thereof. The abnormal-sound detection means detects abnormalities in sounds included in the collected sounds. When an abnormality in a sound is detected by the abnormal-sound detection means, the abnormal-sound generation position identification means identifies the position at which the abnormality of the sound was generated. The abnormal-sound source determination means compares the operation range and the abnormal-sound generation position of the diagnosis object, and determines whether the abnormality of the sound is derived from an abnormality of the diagnosis object.

Dependent claims

An abnormal-sound detection device comprising:

at least one memory storing instructions;
and
at least one processor configured to access the at least one memory and execute the instructions to:
identify an operation range of a diagnosis object, based on a video of the diagnosis object captured by a camera;
sense an abnormality of a sound from among sounds collected by a microphone, the sounds arriving from the diagnosis object;
identify, based on the collected sound, a generation position of the sound in which an abnormality is sensed;
and
determine, based on the operation range, and the generation position of the sound in which an abnormality is sensed, whether the abnormality of the sound is derived from the diagnosis object or derived from another element.
