Ex<loVIrP$ F-tanθ畸变最大显示89度,刚查了手册 >a,w8 ^7 原文如下: D3eK!'qS Note that this reference is meaningless for optical gN*8zui systems that use field angles at or greater than 90 degrees. If a system with field angles over 89 degrees is '?\Hm'8 analyzed with this feature, the maximum computed field angle will be limited to 89 degrees
