如何使用 OSRM 的匹配服务

Question

如 header 中所述：如何使用匹配调用？
我试过了

http://router.project-osrm.org/match/v1/driving/8.610048,46.99917;8.530232,47.051?overview=full&radiuses=49;49

我不确定 radiuses 的列表是否正确。我无法让它工作。我还尝试了 [49;49] 或 {49;49} 该命令适用于 route:

http://router.project-osrm.org/route/v1/driving/8.610048,46.99917;8.530232,47.051?overview=full

背景见

编辑：如果你看一下例子here，它似乎不需要timestamps /match/v1/{profile}/{coordinates}?steps={true|false}&geometries={polyline|polyline6|geojson}&overview={simplified|full|false}&annotations={true|false}

来自docs：

Large jumps in the timestamps (> 60s) or improbable transitions lead to trace splits if a complete matching could not be found.

我认为这是您的请求的问题。给定的两个点相距超过 60s，OSRM 无法匹配成功。 radiuses 指定正确。

以下查询对我有用：

http://router.project-osrm.org/match/v1/driving/8.610048,46.99917;8.620048,46.99917?overview=full&radiuses=49;49

这个returns:

{"tracepoints":[{"location":[8.610971,46.998963],"name":"Alte Kantonstrasse","hint":"GKUFgJEhBwAAAAAAHQAAAAAAAAC5AAAAAAAAAB0AAAAAAAAAuQAAAPsCAACbZIMAsyXNAgBhgwCCJs0CAAAPABki8hY=","matchings_index":0,"waypoint_index":0,"alternatives_count":0},{"location":[8.620295,46.999681],"name":"Schönenbuchstrasse","hint":"nIEFAJ7IFIA3AAAAZAAAAAAAAADYAAAANwAAAGQAAAAAAAAA2AAAAPsCAAAHiYMAgSjNAhCIgwCCJs0CAAAPABki8hY=","matchings_index":0,"waypoint_index":1,"alternatives_count":5}],"matchings":[{"distance":922.3,"duration":114.1,"weight":114.1,"weight_name":"routability","geometry":"onz}Gqyps@Wg@S_@aCaFMUYo@c@w@OKOCWmAWs@aBiDsAsCMYH[HY\_@h@ObBW^w@BQAUKu@ASF[ZaABOFYpAyIf@mD","confidence":0.000982,"legs":[{"distance":922.3,"duration":114.1,"weight":114.1,"summary":"","steps":[]}]}],"code":"Ok"}

所以给定的两个输入点8.610048,46.99917和8.620048,46.99917匹配到8.610971,46.998963和8.620295,46.999681.

据我所知，如果你想实现类似 that 的东西，你需要为 OSRM 提供更多输入点，这些输入点之间的间隔小于 60s。
