Zoom lens cam curve pressure angle optimization method and storage medium

The invention discloses a zoom lens cam curve pressure angle optimization method and a storage medium, and the method comprises the steps: 1, designing an optical system, and obtaining the original discrete displacement data of each motion group; 2, drawing an original cam curve in a rectangular coordinate system; step 3, mapping the horizontal coordinate dimension into a radial component of a cam curve on the surface of the cam cylinder or the cam shaft; 4, establishing a relationship between the pressure angle and the original discrete displacement data point; 5, determining an optimization constraint condition; step 6, optimizing a cam curve; and step 7, fitting the optimized discrete data into a smooth cam curve. According to the optimization method, the whole optimization process is dragged according to the pressure angle design requirement, so that the cam curve matched with the pressure angle optimization constraint condition is obtained through calculation, the original imaging quality of an optical s
