Vehicle-mounted high-quality imaging method based on two-step recovery

The invention relates to a vehicle-mounted high-quality imaging method based on two-step recovery. The method comprises following steps of: S1: expressing the degenerative process of a vehicle-mounted image as the formula shown in the description, wherein f (x, y) is the original clear image, h1 (x, y) is the fixed point spread function of a vehicle-mounted environment imaging system, h2 (x, y) is a motion point spread function under the vehicle-mounted environment, n (x, y) is the additive noise, and g (x, y) is the degenerative image; S2: using a "cepstrum method" to estimate the motion point spread function h2 (x, y) of the g (x, y), and using ultra Lapras regularization ultra resolution algorithm to recover a moving fuzzy image so as to obtain g1 (x, y); and S3: through a "knife edge method", measuring the point spread function h1 (x, y) of a vehicle-mounted optical imaging system, using an improved L-R algorithm to recover the g1 (x, y) fuzzy image and finally recovering a quite clear image f1 (x, y).
