Now the optimizer should have a good starting point. Enable 'use control points of:' for the nadir image, enable Viewpoint optimization for the nadir image, and optimize again.

According to the theory of vanishing point, a novel approach to calibrate the boresight misalignment of airborne position and orientation system (pos) based on photo nadir point is proposed.

Healthy maw is relatively fixed going up celiac, when the person stands, gastric nadir cannot exceed below hilum 2 horizontal strokes to point to (point to) of gastric small turn.
