私は3つの2D地点間で三辺測量を実装しようとしています。私は最終的にこのライブラリTrilaterationを使うつもりだった。私は以下の例を使ってそれを実行しようとしました。コードは次のとおりです三辺測量アプリケーションを使用した2D三角測量
import org.apache.commons.math3.fitting.leastsquares.LeastSquaresOptimizer.Optimum;
import org.apache.commons.math3.fitting.leastsquares.LevenbergMarquardtOptimizer;
import com.lemmingapex.trilateration.NonLinearLeastSquaresSolver;
import com.lemmingapex.trilateration.TrilaterationFunction;
public class Pointofintersection {
public static void main() {
// TODO Auto-generated method stub
double[][] positions = new double[][] { { 5.0, -6.0 }, { 13.0, -15.0 }, { 21.0, -3.0 }, { 12.4, -21.2 } };
double[] distances = new double[] { 8.06, 13.97, 23.32, 15.31 };
NonLinearLeastSquaresSolver solver = new NonLinearLeastSquaresSolver(new TrilaterationFunction(positions, distances), new LevenbergMarquardtOptimizer());
Optimum optimum = solver.solve();
double[] centroid = optimum.getPoint().toArray();
System.out.println(centroid);
//System.out.println(centroid[1]);
}
}
これで、どのような出力が期待できるのでしょうか。私は自分自身を理解できない奇妙な出力を得た。

私が何か間違っているのか、それとも私が解析して他の計算に使うべき本当のデータなのかどうか教えてください。
感謝を。私はデータがダブル配列であることを理解しています。私はちょうどこれらの値が何であるか知りたいですか？そして、私はこれらの価値観と何をするべきでしょうか？それは楕円か円か何かを示すポイントのセットですか？または、私がこのdouble [] centroid = optimal.getPoint（）。toArray（）;で期待するべき値は何ですか？ ありがとうございました –
セントロイドにはセントロイドの座標が含まれています。それは、すべての円が交差する場所について教えてくれます。それは理にかなっていますか？ –
