歷史沿革
本系成立宗旨在整合電子、電機、資訊、控制等多學門之工程技術，以培養跨領域具系統整合能力之電機電子科技人才為目標，同時配合產業界需求、支援國家重點科技發展，以「系統晶片」、「多媒體與通訊」、與「智慧型控制與機器人」等三大領域為核心發展方向，期望藉由學術創新引領產業發展，全力培養能直接投入電機電子產業之高級技術人才，厚植本國科技產業之競爭實力。
本系肇始於民國92年籌設之「應用電子科技研究所」，經一年籌劃，於民國93年8月正式成立，開始招收碩士班研究生，以培養具備理論、實務能力之高階電機電子科技人才為目標。民國96年8月「應用電子科技學系」成立，招收學士班學生，同時間，系所合一為「應用電子科技學系」。民國103年8月更名為「電機工程學系」，民國107年電機工程學系博士班成立，完備從大學部到博士班之學制規模，進一步擴展與深化本系的教學與研究能量。

Item Area measurement system using a single camera(2006-11-11) C.-C. Chen; T.-H. Wang; M.-C. Lu; W.-Y. WangIn this paper, we propose a new method to measure area using only a single CCD camera in different distances. Two parallel laser beams are established to serve as the basis for horizontal length measurement. A single horizontal scanning line of the CCD image is only required for the area measurement. Based on the pixel numbers between two projected points within a CCD image, which represent the resolution of horizontal length, the actual area can be derived by counting the pixel numbers occupied by the image of the object to be measured on the CCD image. Our research results are merited with quick measurement speed, simple system structures and there will be no necessity to adopt image recognizing or signal analysis techniques to calculate the area from different photographing distances.Item A method of distance measurement by digital camera(2006-11-11) T.-H. Wang; C.-C. Hsu; C.-P. Tsai; M.-C. Lu; W.-Y. Wang; C.-C. ChenItem Distance Measurement Using Single Non-metric CCD Camera(2007-08-26) T.-H. Wang; M.-C. Lu; W.-Y. Wang; C.-Y. TsaiA novel measuring system based on a single non-metric CCD camera and a laser projector is proposed in this paper for measuring distance of a remote object. The setup of the measuring system is relatively easy, in which the laser pointer is positioned beside the CCD camera so that laser beam projected is parallel to the optical axis of the camera in a fixed distance. Based on a fast and effective algorithm proposed in this paper, the central position of the projected laser spot in images due to the laser beam can be accurately identified for calculating the distance of a targeted object according to an established formula. Because of the relationship of pixels counts of the diameter of the laser spot at different distances, processing of a sub-frame comprising a fraction of scan lines, rather than the whole image, is only required. Significant savings of computation time can therefore be achieved. Simulation results show satisfactory measurements can be obtained, where averaged absolute measurement errors via the proposed approach lie within 0.502%.Item Electro-Optical Distance and Area Measuring Method(World Scientific and Engineering Academy and Society (WSEAS), 2007-05-01) W.-Y. Wang; M.-C. Lu; T.-H. Wang; Y.-Y. LuThis paper presents a novel distance and area measuring method by using a CCD and remote-controlled robots. Bluetooth wireless modules are used to the control of remote-controlled robots and the communication of the data. In this paper, our system doesn't need to know the height or angle of the camera. Instead we calibrate the image by measuring two lines which are parallel to the horizontal axis of the camera. These two lines are measured using a remote-controlled robot. Changes in the height and or pitch of the camera do not affect the measurements. This is an advantage of the proposed system over traditional methods. From the experiment results, we can see that we can obtain the area measuring results from image without using any complex image identification method, and that the measurement error is acceptable in real situations.
