碩士 === 國立臺灣科技大學 === 電機工程系 === 98 === The technology is improved day by day, and advanced age society is coming, the home safety surveillance system is used wildly. When the accident happened, the monitoring personnel can not be informed immediately leads to injury of the people, therefore the purpose of this thesis is to implement an real-time home safety surveillance system for elderly using stand-alone surveillance system to reduces the personnel casualty, furthermore the monitoring personnel can watch current image by 3G mobile phones any time. The Digital Signal Processor (DSP) has many benefits such as high speed, small size and standalone, for this reason, we use the TI’s TMS320DM642 DSP module as our research developing platform, and with PTZ camera that can use the pan, tilt and the zoom function to make the target stay in the frame. At first, we use the background subtraction to extract the target image from input image, secondly, estimate the posture skeleton from the binary image of the target, and than use the vector quantization to analysis the target’s posture, finally, we can transmit the image to the remote computer, the monitoring personnel can use computer and 3G mobile phones to watch current image, hereby develop a real-time home safety surveillance system.
