by calibrating the camera angle of view, the video images collected from cmos camera are processed by matlab, and the real-time measurement for launching height of signal flare is achieved.
with the camera angle of the picture, it required having a very long stone wall in view.
在最后成图的场景中我有一面很长的石墻。
but as the camera angle changes back and forth her hand switches to the side of his upper arm and back to the shoulder without time to have made the move.
i will mention the limitation of this technique right away: this will be no real fresnel effect, because it is dependent on the camera angle - not really the incidence angle.
