Title:
METHOD FOR CUMULATIVELY DISPLAYING NOISE SOURCE VISUALIZATION DATA, AND SOUND CAMERA SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/200300
Kind Code:
A2
Abstract:
The present invention relates to a method for cumulatively displaying noise source visualization data, the method comprising: a step of providing a sound and image signal obtaining means (100) including MEMS sound detecting sensors (10), a sound signal obtaining unit (20) for transmitting a received sound signal to a central processing unit (40), and a photographing lens (30) for photographing an optical image of a noise source (S10); an initial signal obtaining step of obtaining, by the sound and image signal obtaining means (100), a sound signal and an image of the noise source for a first time frame (T1) (S20); an initial analyzing step of calculating, by the central processing unit (40), beam power (Pij) to generate first sound data, and generating, by the central processing unit (40), image data on the basis of a signal of the photographing lens (30) (S30); an initial display step of coordinating and overlappingly displaying, by a display unit (50), the first sound data and the image data (S40); a cumulative signal obtaining step of obtaining, by the sound signal obtaining unit (20), a sound signal of the noise source for a second time frame (T2) temporally after the first time frame (T1) (S50); a cumulative signal analyzing step of generating, by the central processing unit (40), cumulative sound data on the basis of the sound signal obtained for the second time frame (T2) (S60); and a cumulative display step of displaying, by the display unit (50), the cumulative sound data on an image containing the overlappingly displayed initial sound data and image data (S70).
