Q$1.$ Consider a stereo camera system, with perspective projection matrices:

$M_1=([0\mathrm{.}7,0\mathrm{.}1,0\mathrm{.}4,0\mathrm{.}2],[0\mathrm{.}3,0\mathrm{.}2,0\mathrm{.}2,0\mathrm{.}1],[0\mathrm{.}3,0\mathrm{.}5,0\mathrm{.}6,0\mathrm{.}9]),M_2=([5,7,2,0],[6,8,1,2],[5,9,2,6])$

Compute the $3$D position of the point that projects into the image planes as the following $2$D image

points:

$p_1=(\frac{0\mathrm{.}73214}{0\mathrm{.}37500}),p_2=(\frac{0\mathrm{.}78378}{0\mathrm{.}75676})$
