-代理歐美光學儀器及光學材料:亮度計色度計配光性能光環境測試高吸收發黑塗料高反射材料積分球塗料等。For floodlighting, the luminance and the color of the lighted object depend not only on the power and the color of the illuminant, but also on the color of the lighted object ( the spectral reflectance of the surface ), so, if we choose the optimum matching illuminant for the lighted object in lighting design, we can get excellence and energy efficiency result
摘要:泛光照明中,被照體的亮度大小、顏色變化等視覺效果不但與電光源的功率和光色有關,而且還與物體色(即光譜反射比)等有關,所以在進行照明設計時,應選擇光源色和物體色相匹配的光源,這樣才有可能使泛光照明效果較好,而且達到照明節能的目的。To satisfy the special need, the development of such a multi - purpose photometric and colorimetric instrument is discussed in this paper. in this paper, advantages and disadvantages of available photometric and colorimetric instruments are discussed first. then, a novel instrument is developed, which possesses the following characteristics : utilizing lcd display, flexible keyboard control, integrating capability to perform both photometric and colorimetric measurement so long as the photoelectric detector is changed to another one and corresponding software is performed
本論文研究了以往的光度和色度測量儀的優缺點,設計了利用液晶屏的可視化界面,鍵盤的靈活控制,只要換上不同的光電探頭,啟動不同的測量軟體,就能對光度和色度(如亮度、照度、光通量、色坐標等)進行測量的儀器。The main contents of the thesis are shown as follows : presenting fundamental theories of statistic pattern recognition, discussing rgb ( red, green, blue ) color space, ohta color space, hsi ( hue, saturation, intensity ) color space and its converted color space, materials consistency in gray scale and the application in removing foreign bodies in tobacco flows, hence presenting recognition pattern based on " unit recognition ", designing sample machine for this purpose, which consists of material - providing system, optic system, image - grabbing system, real - time intelligent image - processing system and systems of automatically rejecting foreign bodies and self - diagnosis, analyzing and optimizing hard wares, offering concrete designs such as optic system and air - ejector driver circuit, presenting and realizing physical ram
本文的主要內容有:統計模式識別基礎理論及它們在煙草異物識別中的應用;討論了rgb ( red 、 green 、 blue )基礎顏色空間、 ohta顏色空間、 hsi ( hue色調, saturation飽和度, intensity亮度)顏色空間及其變換空間、物料圖像紋理、灰度均勻性等在煙草異物識別中的應用,並在此基礎上提出了"基於判別單元顏色統計特性"的煙草在線異物識別模型,設計並研製了煙草在線異物實時識別與自動剔除系統原理樣機,它由供料系統、光學系統、圖像數據採集系統、實時智能圖像處理系統、異物自動剔除系統以及自診斷系統等組成。Due to characteristics of white led such as large forward voltage and high temperature sensitivity, and necessity of uniform brightness requirement of the portable application, specially designed power management ic is needed
由於便攜式應用對白光led亮度均勻性的要求,以及白光led自身的正向導通電壓大、電學參數離散性大、容易受溫度影響等特點,需要設計專門的電源管理晶元來驅動白光led 。分享友人
