Active compensation method for manufacturing tolerance of glass aspheric surface in glass-plastic hybrid lens

The invention discloses an active compensation method for manufacturing tolerance of a glass aspheric surface in a glass-plastic hybrid lens. Comprising the following steps: firstly, constructing a first glass-plastic hybrid lens with tolerance and acquiring a real point spread function image; then, a point spread function simulation model is built; calculating a mean square error between the real point spread function image and the simulation point spread function image and taking the mean square error as a loss function to obtain a prediction tolerance and a prediction point spread function image; constructing a second glass-plastic hybrid lens with tolerance according to the design parameters of the first glass-plastic hybrid lens with tolerance and the predicted tolerance, updating six pose variables of the aspheric glass lens, and obtaining an optimal compensation pose; and adjusting the aspheric glass lens of the first tolerance glass-plastic hybrid lens according to the compensation pose to complete ac
