public void distanceSum() {
    RefinePolyLineCorner alg = new RefinePolyLineCorner(true);
    List<Point2D_I32> contour = new ArrayList<>();
    for (int i = 0; i < 20; i++) {
        contour.add(new Point2D_I32(i, 2));
    }
    LineGeneral2D_F64 line = UtilLine2D_F64.convert(new LineParametric2D_F64(0, 0, 1, 0), (LineGeneral2D_F64) null);
    // normal case
    assertEquals(2 * 16, alg.distanceSum(line, 2, 17, contour), 1e-8);
    // boundary case
    assertEquals(2 * 15, alg.distanceSum(line, 10, 4, contour), 1e-8);

Example 2 with LineParametric2D_F64

use of georegression.struct.line.LineParametric2D_F64 in project BoofCV by lessthanoptimal.

the class TestPolylineSplitMerge method assignLine_parametric.

@Test
public void assignLine_parametric() {
    List<Point2D_I32> contour = new ArrayList<>();
    for (int i = 0; i < 20; i++) {
        contour.add(new Point2D_I32(i, 2));
    }
    // make these points offset from all the others. That way if it grabs the wrong points the line will be wrong
