自定义飞行路线管理
超图飞行管理是提前在桌面端定义好飞行路线，然后进行飞行，但是在业务中，有时候需要根据业务需要进行飞行，比如根据GPS取到的点进行实际路径飞行。实现思路：先定义一个空的飞行路径，也可以定义一个只包含一个点的飞行路径来进行定位。然后增加自定义站点，代码如下：
var points = [{x: 116.71275583943516,y: 39.895403435720063,z: -5,altitude: -5.1428938554599881,duration: 11.623106459071682,heading: 0.260995919619558,index:0},{x: 116.71261436907912,y: 39.895686008451534,z: -5,altitude: -5.9814573479816318,duration: 12.33481700746625,heading: 0.0340212,index: 1},{x: 116.71246024545442,y: 39.895982950739153,z: -5,duration:10.964990729795865,altitude: -5.5469268001616001,heading: 0.23512687249191,index: 2},{x: 116.71240014157664,y: 39.896118795529922,z: -5,duration:11.157674687612483,altitude: -4.2948793824762106,heading: 0.205987951731911,index: 3},{altitude: -5.673985555768013,duration: 10,heading: 0.038466827467274554,index: 4,x: 116.71217389893071,y: 39.896766717130667,z: -5},{x: 116.712101305757,y: 39.897437426384997,z: -5,duration:11.157674687612483,altitude: -4.2948793824762106,heading: 0.205987951731911,index: 3}];let routes = new Cesium.RouteCollection();var host = document.location.toString().match(/file:\/\//)?"http://localhost:8080":'http://' + document.location.host;var fpfUrl =host+test.fpf';routes.fromFile(fpfUrl);//添加飞行文件Cesium.when(routes.readyPromise, () => {var route = routes.get(0);this.flyManager = new Cesium.FlyManager({scene: this.viewer.scene, routes: routes});this.flyManager.stopArrived.addEventListener((routeStop) => {
