想要完全没有偏差的 话，那么 就必须确保你 的可见光图片和红外图片外形基本上要保持不变（只是 一些偏转，缩放，位移），但是实际上你的图片红外线的导弹尾部已经淹没在火焰中，没有任何办法能准去计算出尾部的位置的。-To no deviation, then we must ensure the shape of the visible light images and infrared pictures are basically remain the same (just some of the deflection, scaling, and translation), but in fact your picture infrared missile tail has been submerged in flames any way to quasi to calculate the tail position.
