我有一個由Lat Lng座標標識的StreetViewPanorama。 我的Lat和Lng座標並不完全位於Google汽車拍攝照片的道路上,但他們位於我想在StreetView的照片中看到的建築的中心。 所以我有兩個座標,我認爲可以計算POV度以獲得正確的建築物照片。 我需要的是如何獲得自動放置「男人」的點的Lon Lat,以便我可以計算出正確的POV度。Google Maps Api StreetView PanoramaOptions從Lon Lat的角度設置

「相機」的位置是由全景爲getPosition方法返回的經緯度:https://開頭developers.google.com/maps/documentation/javascript/reference#StreetViewPanorama – geocodezip 2013-05-08 14:32:22

問題解決了:

// d is the position of the house or fisical element where I want to point the view 
var d = {lat: 43.538524840485, lng: 10.322718769311}; 
var whereToLookLatLng = new google.maps.LatLng(parseFloat(d.lat), parseFloat(d.lng)); 
var panorama = new google.maps.StreetViewPanorama(
    document.getElementById('pano'), 
    panoramaOptions 
); 
map.setStreetView(panorama); 

var service = new google.maps.StreetViewService; 
// With this function I get the panorama, if available, next the house or fisical element where I want to point the view 
service.getPanoramaByLocation(panorama.getPosition(), 50, 
    function(panoData) { 
     if (panoData != null) { 
      // MamLatLng is the position of the point of view 
      var ManLatLng = panoData.location.latLng; 
      // Now I calculate the heading to point the view in the direction of whereToLookLatLng 
      var heading = google.maps.geometry.spherical.computeHeading(ManLatLng, whereToLookLatLng); 
      var pov = panorama.getPov(); 
      pov.heading = heading; 
      panorama.setPov(pov); 
     } 
    }); 
}

我實現kiks73的解決方案。

確保在加載地圖API時添加幾何庫:

https://maps.googleapis.com/maps/api/js?v=3.exp&libraries=visualization,places,geometry&sensor=true 

var dist = 50; 

service.getPanoramaByLocation(targetLatLng, dist, function(panoData){ 
    panoramaLatLng = panoData.location.latLng; 
    initStreetView(targetLatLng, panoramaLatLng)  
}); 

function initStreetView(targetLatLng, panoramaLatLng){ 

    var panoramaOptions = { 
     position: targetLatLng 
    }; 

    var streetView = new google.maps.StreetViewPanorama(document.getElementById('streetView'),panoramaOptions); 
    var heading = google.maps.geometry.spherical.computeHeading(panoramaLatLng, targetLatLng); 
    map.setStreetView(streetView);  
    streetView.setPov({heading:heading, pitch:0});     

}
