projection of the point 𝑃 onto the image plane is 𝑃′. The coordinates of 𝑃 are (𝑥, 𝑦, 𝑧), and the coordinates of 𝑃′ are (𝑥′, 𝑦′, 𝑓). Our goal is to find the coordinates of 𝑃′. from the figure, △OMP and △OO′P′ are similar triangles. ⟹ x′/x = y′/y = f/z ⟹ x′ = x ∗ f/z and y′ = y ∗ f/z We’ve found the
