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 Image-Based System for Measuring Objects on an Oblique Surface(2010-05-06) Chen-Chien Hsu; Wei-Yen Wang; Yin-Yu Lu; Ming-Chih LuThis paper presents an image-based framework for measuring target objects on an oblique plane by using a single CCD camera and two parallel laser projectors beside the camera. Because of the alignment of the laser beams which form in parallel with the optical axis, projected spots in the image can be processed to establish relationships between distance and pixel counts between the projected spots in the image. Based on simple geometrical derivations without complex image processing, the proposed approach can measure the photographing distance, the distance between two arbitrary points on the oblique surface, and the incline angle. Experiment results have demonstrated the effectiveness of the proposed approach in measuring distant objects on an oblique plane.Item Distance and Angle Measurement of Distant Objects on an Oblique Plane Based on Pixel Variation of CCD Image(2010-05-06) Ming-Chih Lu; Chen-Chien Hsu; Yin-Yu LuThis paper presents an image-based system for measuring target objects on an oblique plane based on pixel variation of CCD images for digital cameras by referencing to two arbitrarily designated points in image frames. Based on an established relationship between the displacement of the camera movement along the photographing direction and the difference in pixel counts between reference points in the images, photographing distance between the camera and an object on the oblique target plane can be calculated via the proposed method.Item Distance Measurement Based on Pixel Variation of CCD Images(2009-02-12) Chen-Chien Hsu; Ming-Chih Lu; Ke-Wei ChinThis paper presents a distance measurement method based on pixel number variation of images for digital cameras by referencing to two arbitrarily designated points in image frames. Based on an established relationship between the displacement of the camera movement along the photographing direction and the difference in pixel counts between reference points in the images, distance from an object can be calculated via the proposed method. To integrate the measuring functions into digital cameras, circuit design implementing the proposed measuring system in selecting reference points, measuring distance, and displaying measurement results on CCD panel of the digital camera is proposed in this paper. In comparison to pattern recognition or image analysis methods, the proposed measuring approach is simple and straightforward for practical implementation into digital cameras. Experiment results have demonstrated that the proposed method is capable of yielding satisfactory measurement results in a very responsive way.Item Distance Measurement Based on Pixel Variation of CCD Images(Elsevier, 2009-10-01) Chen-Chien Hsu; Ming-Chih Lu; Wei-Yen Wang; Yin-Yu LuThis paper presents a distance measurement method based on pixel number variation of CCD images by referencing to two arbitrarily designated points in the image frames. By establishing a relationship between the displacement of the camera movement along the photographing direction and the difference in pixel count between reference points in the images, the distance from an object can be calculated via the proposed method.

In comparison to pattern recognition or image analysis methods, the proposed measuring approach is simple and straightforward for practical implementation into digital cameras. To validate the performance of the proposed method, measurement results using the proposed method and ultrasonic rangefinders are also presented in this paper.
