Web12 de nov. de 2012 · Delaunay's Triangulation is named for Boris Delaunay. The general idea is to form a mesh where each triangle's three points lie on the edge of a circle that doesn't contain any other point. This means given any two adjacent triangle's (quadrilateral) the sum of the angles opposite the dividing line are less than 180 degrees. Web29 de dez. de 2024 · It only works with undistorted 2D points. Distorted points will ruin your triangulation. So: Calibrate your camera, get the intrinsic matrix and distortion coefficients; Use undistortPoints; Use triangulatePoints; Most modern pinhole cameras have small distortion, you can make them work without undistort your points.
