描述
combine_roads_xldcombine_roads_xldCombineRoadsXldCombineRoadsXldCombineRoadsXldcombine_roads_xld 结合来自两个不同分辨率级别的道路假设。该算法仅选择在两个分辨率级别中相互支持的假设。参数 EdgePolygonsEdgePolygonsEdgePolygonsEdgePolygonsedgePolygonsedge_polygons、ModParallelsModParallelsModParallelsModParallelsmodParallelsmod_parallels 和 ExtParallelsExtParallelsExtParallelsExtParallelsextParallelsext_parallels 对应最高分辨率级别的道路假设。参数 CenterLinesCenterLinesCenterLinesCenterLinescenterLinescenter_lines 是较低分辨率级别中道路提取的结果。仅当多边形 EdgePolygonsEdgePolygonsEdgePolygonsEdgePolygonsedgePolygonsedge_polygons
在两个分辨率级别中均被识别为道路边界时才会被返回。参数 MaxAngleParallelMaxAngleParallelMaxAngleParallelMaxAngleParallelmaxAngleParallelmax_angle_parallel 和 MaxAngleColinearMaxAngleColinearMaxAngleColinearMaxAngleColinearmaxAngleColinearmax_angle_colinear 分别限定两条平行共线线段可形成的最大夹角。参数 MaxDistanceParallelMaxDistanceParallelMaxDistanceParallelMaxDistanceParallelmaxDistanceParallelmax_distance_parallel 和 MaxDistanceColinearMaxDistanceColinearMaxDistanceColinearMaxDistanceColinearmaxDistanceColinearmax_distance_colinear 分别限定两条平行线段或共线线段的最大允许距离。组合过程遵循多项规则进行。
执行信息
- 多线程类型：互斥（可与其他非互斥算子并行运行，但不能与自身并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。
