圆形目标的鱼眼相机成像模型推导

Imaging Model Derivation of Circular Target Based on Fish-eye Camera

圆形目标在现实生活和工业领域中大量存在,利用鱼眼相机可实现高效的圆形目标检测.介绍了等距投影、等立体角投影、正交投影、体视投影等4种常用的鱼眼相机投影模型,并分别推导了圆形目标在不同投影模型下的理论公式,为利用鱼眼相机检测圆形目标提供了理论基础.

Circular targets abound in real life and industrial areas,and it can be efficiently detected by using fish-eye camera. Four kinds of commonly used fish-eye camera projection models,such as equidistance projection, equisolid projection,orthogonal projection,and stereo graphic projection models,are introduced,and then the imaging models of circular targets under different projection models are deduced,which provides a theoretical basis for using the fish-eye camera to detect circular targets.
