High-speed parabolic detection and tracking method and system in complex light environment

The invention belongs to the technical field of high-speed parabolic detection, and particularly relates to a high-speed parabolic detection and tracking method and system in a complex light environment. Comprising the following steps: S1, acquiring a road information image, and framing; s2, performing parabolic detection and recognition on the frame with the parabolic for the first time, and importing a Gaussian mixture model to obtain a foreground image; determining a closed contour of the parabolic foreground, and completing initialization of a contour template of the parabolic foreground; s3, acquiring a foreground target, and performing morphological processing of first expanding and then corroding on a foreground image; s4, introducing a Hu moment discrimination condition, and carrying out Hu moment threshold discrimination; s5, introducing a prediction frame center offset discrimination condition, and limiting a prediction frame offset distance; and S6, for frames which do not meet the Hu moment discri
