【摘要】：為了提高無人駕駛汽車對中遠(yuǎn)距離車輛目標(biāo)的識別準(zhǔn)確率,滿足無人駕駛汽車對前方預(yù)瞄距離的要求,通過理論計算以及光學(xué)設(shè)計軟件ZEMAX-EE,研究設(shè)計了一款適合安裝于乘用車上的中遠(yuǎn)距離車載鏡頭。為了滿足車載鏡頭在實際使用過程中對成像范圍的要求,利用成像景深公式計算了對準(zhǔn)距離為無窮遠(yuǎn)時,不同入瞳直徑對應(yīng)的成像范圍,從而確定了滿足實際使用條件、易于設(shè)計和檢驗的鏡頭參數(shù)設(shè)計方案。車載鏡頭的焦距為40mm,視場角為8.6°,入瞳直徑為7mm,景深為30m~+∞,系統(tǒng)總長小于38mm。仿真分析結(jié)果表明,所設(shè)計車載鏡頭具有良好的成像質(zhì)量,能夠滿足實際的使用要求。
[Abstract]:In order to improve the accuracy of vehicle target recognition for medium and long distance vehicles, and to meet the requirement of preview distance in front of driverless vehicles, theoretical calculation and optical design software ZEMAX-EE, are used. In this paper, a long-distance vehicle lens suitable for passenger cars is designed. In order to meet the requirements of imaging range of vehicle lens in practical use, the imaging range corresponding to different entrance pupil diameters when the alignment distance is infinite is calculated by using the imaging depth formula, and the practical application conditions are determined. Easy to design and test the design of lens parameters. The lens has a focal length of 40 mm, a field of view angle of 8.6 擄, a pupil diameter of 7 mm and a depth of field of 30 m ~ 鈭，
