摘　　要：研究鱼眼镜头成像模型,对鱼眼镜头的3种畸变,包括径向畸变、偏心畸变(切向畸变)和薄棱镜畸变进行了分析,并建立了各自的数学模型.最后根据投影规律得出3种畸变校正模型:等距修正模型、等立体角修正模型和正交校正模型.Model of fish-eye lens is studied,the three kinds of distortion of the fish-eye lens,including the radial distortion,distortion eccentric（tangential distortion）,and thin prism distortion are analyzed,and their own mathematical model are established.Finally,3 kind of distortion adjustment model are obtained according to the projection rule,including equal-space revision model,defined solid angle correction model and orthogonal correction model.
