RANCANG BANGUN ALAT MIKROFON DENGAN MENERAPKAN PENDETEKSI WAJAH UNTUK MENYESUAIKAN POSISI MULUT DENGAN MIKROFON
Abstract
The development of technology in the field of image processing has been
developed, where the camera as a sensor has been widely applied in various fields
such as defense, equity, environment, medicine and social. With the development of
technology in the field of image processing many systems that switch from
conventional to an automatic system that can facilitate human activities. If it
focuses on the social field, to interact to the public the technology used is a
microphone. However, with one microphone used the sound captured from the
speaker is not optimal and makes the public unable to hear the message delivered
properly. Departing from that, then in this study designed a microphone that is able
to move automatically follow the face of the speaker with the camera as a face
detection. This study provides the ease of communicating in public, which does not
require many microphones and spiral microphones. The working system of this tool
is quite easy, where the camera will detect the face in front of the tool so that the
microphone can follow the face detected by the camera. In this tool there are two
servo motors capable of moving the microphone vertically and horizontally by
using Arduino UNO R3 microcontroller as the controller's brain. The results of this
study where the microphone designed image processing system so as to perform
face detection and can capture the sound of the speaker with an optimal sound
intensity of 60 - 70 decibels (dB).
