PARKING ASSISTANT SYSTEM USING BLUETOOTH COMMUNICATION, ESPECIALLY CONCERNED WITH SENSING THE BLIND SPOT OF THE REAR OR CORNER PART OF A VEHICLE THROUGH A CCD CAMERA AND AN ULTRASONIC SENSOR AND DISPLAYING IT ON THE LCD SCREEN OF A MOBILE PHONE BY USING BLUETOOTH COMMUNICATION

摘要

PURPOSE: A parking assistant system using Bluetooth communication is provided to detect the blind spot of the rear or corner part of a vehicle through a CCD camera and an ultrasonic sensor and to display it on the LCD screen of a mobile phone using Bluetooth communication. CONSTITUTION: A parking assistant system using Bluetooth communication consists of a CCD camera(10), an ultrasonic sensor(11), a CPU(13), a video decoder(14), a communication interface(15), a video encoder(16), and a power supplier(P). The CCD camera(10) and the ultrasonic sensor(11) are installed at the rear part of a vehicle. The video decoder(14) converts an image pickup signal inputted from the CCD camera(10) into a video signal and forwards it to the CPU(13). The communication interface(15) converts a signal inputted from the ultrasonic sensor(11) into a sensor signal and forwards it to the CPU(13). The video encoder(16) converts the video signal and the sensor signal, forwarded from the CPU(13), into signals for wired/wireless transmission and selectively outputs either of them to a display unit. The power supplier(P) supplies power to the components.
