Google Maps Api StreetView PanoramaOptions从Lon Lat的角度设置

Question

我有一个由Lat Lng坐标标识的StreetViewPanorama。 我的Lat和Lng坐标并不完全位于Google汽车拍摄照片的道路上，但他们位于我想在StreetView的照片中看到的建筑的中心。 所以我有两个坐标，我认为可以计算POV度以获得正确的建筑物照片。 我需要的是如何获得自动放置“男人”的点的Lon Lat，以便我可以计算出正确的POV度。

问题解决了：

// 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); 
     } 
    }); 
}

我实现kiks73的解决方案。

确保在加载地图API时添加几何库：

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});     

}
