在Java中,可以使用JTS(Java Topology Suite)库来获取点到线段的垂足点。以下是一个简单的示例代码,展示了如何使用JTS获取点到线段的垂足点:
首先,确保你的项目中包含了JTS库。
import org.locationtech.jts.algorithm.distance.DistanceToPoint;
import org.locationtech.jts.algorithm.distance.PointPairDistance;
import org.locationtech.jts.geom.LineString;
import org.locationtech.jts.geom.Point;
import org.locationtech.jts.io.ParseException;
import org.locationtech.jts.io.WKTReader;
public class VerticalFootExample {
public static void main(String[] args) throws ParseException {
PointPairDistance pointPairDistance = new PointPairDistance();
WKTReader wktReader = new WKTReader();
//线L1
LineString lineString = (LineString) wktReader.read("LINESTRING (103.823703 36.058191,103.823676 36.054882,103.829764 36.054903)");
//点p1
Point point = (Point) wktReader.read("POINT (103.827083 36.057880)");
DistanceToPoint.computeDistance(lineString, point.getCoordinate(),pointPairDistance);
System.out.println("距离:"+pointPairDistance.getDistance()*100000+"米,垂足点:"+pointPairDistance.getCoordinate(0));
}
}
确保你的类路径中包含了JTS库,然后运行上述代码,它会输出点到线段所在直线上的垂足点的坐标。
