Ch7 triangulation, depths are close to 10

[mnslarcher]

In ch7 if I execute triangulation

./build/triangulation 1.png 2.png

I get:

Is this correct? With these values less than or close to 10, all key points have the same color in the two images.

If the depths are correct, maybe it would be better to change the range in get_color?

Thanks, Mario
