java获得数组交叉点_java – 如何从ElasticSearch中的形状获取交叉点

我已将ElasticSearch中的路径存储为Polygon.现在我有一个圆(一个点和一个半径),我能够检查圆点与多边形是否相交(下面是我使用的代码).

问题：如何获得与圆相交的路线中的点？

public Boolean isMatchingDoc(Long elasticDocId,Double latitude,Double longitude,Long radius) {

Coordinate origin = new Coordinate(latitude,longitude);

ShapeBuilder circleShapeBuilder = ShapeBuilder.newCircleBuilder().center(origin).radius(radius,DistanceUnit.METERS);

GeoShapeQueryBuilder geoShapeQueryBuilder = QueryBuilders.geoShapeQuery("route",circleShapeBuilder);

SearchRequestBuilder finalQuery = client.prepareSearch(INDEX).setTypes(TYPE)

.setQuery(QueryBuilders.termQuery("_id",elasticDocId)).setPostFilter(geoShapeQueryBuilder);

SearchResponse searchResponse = finalQuery.execute().actionGet();

SearchHits searchHits = searchResponse.getHits();

if (searchHits.getTotalHits() > 0) {

return true;

}

return false;

}
