从 Google 街景获取 lat/lng/zoom/yaw/pitch

发布于 2024-07-16 04:04:18 字数 269 浏览 8 评论 0原文

我有一个基于提供的纬度/经度坐标、缩放、偏航和俯仰的谷歌地图和街景。每当任何详细信息从默认值更改或单击按钮时，我都需要调用 JavaScript 来更新每个值的隐藏字段。

因此，每当地图/街景视图被放大、平移、倾斜等时，它都会输出新的细节。

每当街景视图更改时，如何调用函数 getPOV()、yawchanged(yaw:Number)、pitchchanged(pitch:Number) 和 Zoomchanged(zoom:Number)（类似于地图的 moveend）

不确定压缩它的最佳方法，但这可以获取更改的详细信息：

GEvent.addListener(myPano, 'initialized', function(pano) {
  alert("newlng: " + pano.latlng.lng() + ", newlat: " + pano.latlng.lat());
});

GEvent.addListener(myPano, 'yawchanged', function(newyaw){
  alert("yawchanged: " + newyaw);
});

GEvent.addListener(myPano, 'pitchchanged', function(newpitch) {
  alert("pitchchanged: " + newpitch);
});

GEvent.addListener(myPano, 'zoomchanged', function(newzoom) {
  alert("zoomchanged: " + newzoom);
});

Not sure of the best way to compress this but this works to get the changed details:

GEvent.addListener(myPano, 'initialized', function(pano) {
  alert("newlng: " + pano.latlng.lng() + ", newlat: " + pano.latlng.lat());
});

GEvent.addListener(myPano, 'yawchanged', function(newyaw){
  alert("yawchanged: " + newyaw);
});

GEvent.addListener(myPano, 'pitchchanged', function(newpitch) {
  alert("pitchchanged: " + newpitch);
});

GEvent.addListener(myPano, 'zoomchanged', function(newzoom) {
  alert("zoomchanged: " + newzoom);
});

我通常发现“moveend”是用作钩子的最佳事件，用于在用户更改地图时获取地图的状态。当我今天下午有更多时间时，我需要查找如何从地图中获取纬度/经度、缩放、偏航和俯仰角

// map is the instance of your GMap2
GEvent.addListener(map, 'moveend', function() {
  var center = map.getCenter();
  var zoom = map.getZoom();

  alert([center.lat(), center.lng(), zoom].join(','));
});

I generally have found that "moveend" is the best event to use as a hook to get the state of the map when a user changes it. I will need to look up how to get the lat/lng, zoom, yaw, and pitch from the map isntanct when I have more time this afternoon

// map is the instance of your GMap2
GEvent.addListener(map, 'moveend', function() {
  var center = map.getCenter();
  var zoom = map.getZoom();

  alert([center.lat(), center.lng(), zoom].join(','));
});

对于谷歌地图 API v3...假设您已经加载了名为“panorama”的街景地图

google.maps.event.addListener(panorama, "pov_changed", function() { 
   var panoInfo   = panorama.getPov();
   var thePitch   = panoInfo['pitch'];
   var isHeading  = panoInfo['heading'];
   var theZoom    = panoInfo['zoom'];
});

For google maps api v3... Assuming you have a streetView map already loaded named "panorama"

google.maps.event.addListener(panorama, "pov_changed", function() { 
   var panoInfo   = panorama.getPov();
   var thePitch   = panoInfo['pitch'];
   var isHeading  = panoInfo['heading'];
   var theZoom    = panoInfo['zoom'];
});
