(1) Code V中計(jì)使用 eva (oal s1..i z1)計(jì)算鏡頭長度時(shí)是把像面離焦量包含在內(nèi)的。
EKEJ9Y+47H (2) 使用movie.len,計(jì)算其三個(gè)變焦位置的總長如下
l\ VrD2j8 (OAL Z1 S1..I) = 107.522580166499
?HeUU (OAL Z2 S1..I) = 107.568305499122
&"^U=f@v (OAL Z3 S1..I) = 107.525471335228
&mm!UJ 不一樣長。拿掉離焦量

ED 再計(jì)算一次總長如下
#gXxBM (OAL Z1 S1..I) = 107.554580166499
I8uFMP (OAL Z2 S1..I) = 107.542305499122
i ;^Ya (OAL Z3 S1..I) = 107.544471335228
5t-,5 還是不一樣長。說明此案例在沒有離焦時(shí)也無精確保持等長。也可以不用歸零離焦量而直接求得同樣長度如下
`yO'-(@"gY (OAL Z1 S1..I)-(CT SI Z1) = 107.554580166499
"egpc*|] (OAL Z2 S1..I)-(CT SI Z2) = 107.542305499122
