The invention discloses a short-focus projection dynamic
distortion compensation method based on depth vision modeling, and the method comprises the following steps: S1, collecting the multi-
modal vision information of a projection region, and forming a vision
data set; s2, inputting into an improved Instant-NGP model, and generating a three-
dimensional modeling result; s3, constructing a spatial attitude matrix; s4, generating a nonlinear mapping
tensor of the
projection image space and the surface space; s5, performing pixel redirection
processing on the original
projection image to generate a
distortion compensation image; s6, constructing a residual image, calculating a structure deviation value and an edge offset, and updating a nonlinear mapping
tensor; and S7, dynamically adjusting the reconstruction frequency of the improved Instant-NGP model, the updating frequency of the nonlinear mapping
tensor and the output frequency of the
distortion compensation image to form a dynamic compensation
closed loop. According to the invention, pixel-level dynamic distortion compensation in a short-focus projection scene is realized, and the method has the technical advantages of high modeling precision, fast compensation response and strong space consistency.
