You can’t use the GPS technique because the timing is nothing like accurate enough. The best you can do is Trilateration based on the signal strength from each base station and assume that range is proportional to signal. You will probably need to force a connection to each base station in turn in order to … Read more
To give you some more choices of libraries out there: Polyboolean. I never tried this one, but it looks promising: http://www.complex-a5.ru/polyboolean/index.html General Polygon Clipper. This one works very well in practice and does triangulation as well as clipping and holes holes: http://www.cs.man.ac.uk/~toby/alan/software/ My personal recommendation: Use the tesselation from the GLU (OpenGL Utility Library). The … Read more
If you mean centroid, you just get the average of all the points. x = [p[0] for p in points] y = [p[1] for p in points] centroid = (sum(x) / len(points), sum(y) / len(points))
If you want to construct the 2D Delaunay triangulation, use Triangle.Net. It is a direct C# port of Shewchuk’s famous Triangle program.
1.- The method used is Least Squares. There are more complex algorithms than this one. Still, it is the most common one, as the other methods may fail in some cases (i.e. some others fail if points are on a plane or at infinite). The method can be found in Multiple View Geometry in Computer … Read more
The function cv::undistort does undistortion and reprojection in one go. It performs the following list of operations: undo camera projection (multiplication with the inverse of the camera matrix) apply the distortion model to undo the distortion rotate by the provided Rotation matrix R1/R2 project points to image using the provided Projection matrix P1/P2 If you … Read more
