Abstract:	汽車完全自動駕駛的技術目前發展雖然尚未成熟，但是先進駕駛輔助系統(Advanced Driver Assistance Systems；ADAS)相關應用已快速崛起。本研究目的是設計應用在先進駕駛輔助系統中的前視鏡頭，最終產品具有車道偏移、自動剎車、行人偵測，自動跟車等功能。本研究提出一種前視鏡頭之光學設計，透過Zemax軟體進行光路模擬、性能評價及溫度飄移分析，利用Code V軟體進行公差分析，模擬鏡頭生產良率，最後用ASAP軟體進行鏡頭雜散光分析及改善。完成之鏡頭設計規格為使用一百萬畫素，1/2.56〞感測器，水平視角為52度，光圈值1.62，鏡頭總長12.6mm，其光學架構採用三片玻璃球面鏡片及二片模造非球面鏡片，鏡頭生產良率90%以上，在溫度-40°C~105°C的範圍有良好的聚焦特性。 ;Although the technology of fully automatic driving of automobiles is not yet mature, the application of Advanced Driver Assistance Systems (ADAS) has rapidly emerged. The purpose of this study is to design a front-view lens for use in advanced driver assistance systems. The final product has features such as lane offset, automatic braking, pedestrian detection, and automatic follow-up. The research of this paper has brought up a lens optical configuration, which adopts a three spherical glass lens and two aspheric molded lenses based on a one mega pixel imager sensor design for advanced driving assistance system application. By simulating optical routes, performance evaluation and thermal drifting analysis via Zemax software and using Code V software to conduct tolerance analysis to understanding manufacturing yield rate and further carry out flare and ghost analysis via ASAP software to fully understand the development process of an automotive lens design stages. The completed lens design specification uses one million pixels, 1/2.56 〞 sensor, horizontal viewing angle of 52 degrees, aperture value of 1.62, total lens length of 12.6mm, and its optical structure uses three glass spherical lenses and two molded aspherical lenses, the lens production yield is above 90%, and has good focusing characteristics in the temperature range of -40 ° C ~ 105 ° C.
