Web10 jan. 2024 · 3.1 Network model for homography prediction. Having estimated which pixels belong to the lane mark, we are supposed to fit these pixels into a parametric curve with outliers removed. The lane pixels are first projected into a BEV representation, in which the lanes have a parallel-like shape and their curvature can be fitted with low-order … WebCheck out this illustration of a camera and world plane. There exists a linear transformation between the camera projection and the world plane, since the world plane has two dimensions like an image plane. Find the Homography Matrix. To find the homography matrix, you should first determine the pixel coordinates of several real world points.
