沿革
科技與工程學院（原名為科技學院）於87學年度成立，其目標除致力於科技與工程教育師資培育外，亦積極培育與科技產業有關之工程及管理專業人才。學院成立之初在原有之工業教育學系、工業科技教育學系、圖文傳播學系等三系下，自91學年度增設「機電科技研究所」，該所於93學年度起設立學士班並更名為「機電科技學系」。本學院於93學年度亦增設「應用電子科技研究所」，並於96學年度合併工教系電機電子組成立「應用電子科技學系」。此外，「工業科技教育學系」於98學年度更名為「科技應用與人力資源發展學系」朝向培育科技產業之人力資源專才。之後，本院為配合本校轉型之規劃，增加學生於科技與工程產業職場的競爭，本院之「機電科技學系」與「應用電子科技學系」逐漸朝工程技術發展，兩系並於103學年度起分別更名為「機電工程學系」及「電機工程學系」。同年，本學院名稱亦由原「科技學院」更名為「科技與工程學院」。至此，本院發展之重點涵蓋教育（技職教育/科技教育/工程教育）、科技及工程等三大領域，並定位為以技術為本位之應用型學院。
107學年度，為配合本校轉型規劃，「光電科技研究所」由原隸屬於理學院改為隸屬本（科技與工程）學院，另增設2學程，分別為「車輛與能源工程學士學位學程」及「光電工程學士學位學程」。

Item Image-based distance and area measuring systems(IEEE Sensors Council, 2006-04-01) M.-C. Lu; W.-Y. Wang; C.-Y. ChuIn this paper, a novel measuring system using a scancounter method via a CCD camera is proposed. The proposed measuring system is an easy-to-construct system to measure the distance between a CCD camera and an object, and to measure the projected area of the object. This measuring method needs not store huge amounts of image data nor use any pattern recognition approach. It quickly obtains the distance and the projected area using simple circuits and formulas. For distance measurement, two laser projectors are set on either side of a CCD camera and produce two parallel rays that project two bright spots on the object and, therefore, on the CCD. An external clock, which is generated by an extra oscillator, is used to measure the time interval between the two bright spots as the CCD scans the image. A circuit for counting the number of external clock pulses between the two bright spots is employed to calculate the interval between them in the video image. Due to the parallel setup of the distance measuring system, there is a linear relationship between the actual distance and the interval of the two bright spots. Therefore, the actual distance from the CCD camera to the object can be calculated from a simple formula. For area measurement, circuits count the number of external clock pulses of the horizontal scan lines covering the projected area of the object. Then, the projected area of the object is calculated from simple algebraic formulas. Finally, several experimental results demonstrate the effectiveness of the proposed system.Item Three Dimensional Measurement of Distant Objects Based on Laser-Projected CCD Images(Institution of Engineering and Technology, 2009-05-01) C.-C. Hsu; M.-C. Lu; W.-Y. Wang; Y.-Y. LuA novel measuring system based on a single CCD camera and two laser projectors to record images and perform three-dimensional measurement of a distant object is proposed here. Because of the alignment of the laser beams which form in parallel with the optical axis of the CCD camera, projected spots will appear on the same scan line in a CCD image. As a result processing of a single scan line rather than the whole image is only required to identify the projected spots in the CCD image. Complex computation of video signals of the whole image via either pattern recognition or image analysis methods is therefore circumvented. On the basic of an established relationship between the distance and pixel counts between the projected spots in the CCD image, the proposed system not only measures the distance from a distant object but also the length of two arbitrarily designated points on the object. To provide better accuracy, intrinsic parameters of the CCD camera are taken into consideration in the measurement. Furthermore, the effect of laser diffusion is also proved to be irrelevant to the measuring accuracy here. Experimental results have demonstrated that the proposed measuring method is capable of yielding accurate results of three-dimensional measurement for a distant object in a very responsive way.Item Distance measurement based on pixel variation of CCD images(ISA, 2009-10-01) C.-C. Hsu; M.-C. Lu; W.-Y. Wang; Y.-Y. LuThis paper presents a distance measurement method based on pixel number variation ofimages 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 resultsin a very responsive way.
