    1.touyingmiande kuanw yu gaoh yiji touyingjulid

    2.touyingjidefenbianlv touyinghuamianbiliiw/ih ,touyingjitoushebitr

    01 一字型横向融合(1xN)

    diyibu:yizhitouyingmiangaokuanyijitouyingjitouyingbili,qiuxianchangxuyaojitaitouyingji,bingyongronghedaibilizuihaobushaoyutouyinghuamiande30%yansuanyixia。

    给你一个公式:

    n=1.25x(w/h)/(iw/ih)

    (zuihoudaanquzhengbianshitouyingjitaishu)

    jugelizi:

    8mikuan,2migaodeqiangmianzuotouying,xuanyong16:9detouyingji,neixuyaojitaitouyingjini?

    1.25x(8/2)/(16/9)≈2.8 quzheng3 yincixuyao3taitouyingji

    验算融合带比例(不少于30%):

    tongguo16:9desheyingjisuanchu,dantaitouyinghuamiangao2mi,kuan3.5mi,3taitouyingjidezongtouyinghuamiankuanduwei3x3.5=10.5mi,zongronghedaikuanduwei10.5-8=2.5mi,ronghedaibaifenbi(2.5/3.5)/2 ≈36% ,fuhebiaozhun√

    再举个例子:

    12mikuan,2.5migaodemubu,yong4:3detouyingji,xuyaojitaitouyingjini?

    1.25x(12/2.5)/(4/3)≈4.6 quzheng5 yincixuyao5taitouyingji

    验算融合带比例(不少于30%):

    tongguo4:3touyingjisuanchu,dantaitouyinghuamiangao2mi,kuan2.66mi,5taitouyingji4geronghedai,zongronghedaikuanduwei5x2.66-12=1.3mi,meigeronghedaibaifenbi(1.3/2.66)/4≈12.2%,ronghedaitaixiao,bufuhebiaozhun×

    kaolvzaijiayitaitouyingji,neijiushi6getouyingji,5geronghedai,zongronghedaikuan6x2.66-12=3.96mi,ronghedaiwei(3.96/2.66)/5≈30%,mianqiangfuhebiaozhun√

    第二步:确定投影机的投射比TR参数,计算投影机放置位置

    jiniyigegongshi:

    touyingjifangzhijuli=trxiw

    举个例子:

    dantaitouyinghuamiangao2kuan3.5,jiashetouyingjitrwei1.5-1.9,neimetouyingjifangzai3.5x1.5-3.5x1.9deweizhijike,yejiushi5-6mizuoyou。

    02 一字型竖向融合(Nx1)

    ruguoyudaoshutouxitong,neimejiubajisuangongshin=1.25x(w/h)/(iw/ih)deiw/ihhuanchengih/iw

    03 弧形幕融合
