- I don't think my work for this problem is correct. The data is given in the images. There was no physical experiment doneA scene point with coordinate (X, Y, Z) = (α, β, γ) in the world is perspectively projected into an image at coordinate (x, y) = (δ, ϵ), where both coordinates are given in millimeters in the camera coordinate frame and the camera’s principal point is at coordinates (0, 0, f). The camera reference frame is translated ζ mm in the negative direction along the z-axis relative to the world reference frame. What are values for the camera intrinsics and extrinsics? Show all your work.Consider a refracting prism shown below. The face opposite the apex (top of the prism) is called the base. The total angle by which light changes direction is called the angle of deviation D. I A to a. Show that nprism = sin(A+D)/2/ sin (A/2) when light passes through the prism symmetrically such that the angles of incidence (1) and emergence (E) are equal (Assume the angle A is 60°) b. Find the deviation angles for blue and red light having indices of refraction 1.652 and 1.618 respectively. c. Sketch what happens when white light is incident on the prism. I
