Google Street View JS - FoV＆FoV Event

问题描述：

我正在构建一个应用程序，使用Google街景视图API中的图片。我需要放大图像。Google Street View JS - FoV＆FoV Event

我正在使用事件pov_changed，我跟踪对POV音高和标题的更改。要决定最终图像的缩放比例，我需要一个FoV（视野）属性。

https://maps.googleapis.com/maps/api/streetview?size=700x600&location=40.159172842909,-103.201315097248&heading=22.3118227257402&pitch=-1.42049583899625&key=<key>&fov=20

我有这样的设置...

center = new google.maps.LatLng(address.latitude, address.longitude) 

    map = new google.maps.Map(document.getElementById('map'), { 
    center: center, 
    zoom: address.zoom 
    }) 

    street = new google.maps.StreetViewPanorama(document.getElementById('street'), { 
    position: center, 
    pov: { 
     heading: address.pov_heading || 150, 
     pitch: address.pov_pitch || 0.75 
    } 
    })

要获得获取值更新形式，我有一些事情一样......但我无法找到如何获得视野属性。

street.addListener 'pov_changed', -> 
    pitchField.html(street.getPov().pitch) 
    headingField.html(street.getPov().heading) 
    # console.log(street.getFov()) # is not a function 
    # console.log(street.getFoV()) # is not a function 
    # console.log(street.getFOV()) # is not a function

如何查找要在链接中使用的视野以放大图像。

@ anatoly.sukhanov：如何获得FOV是这个问题，我只需要找到FOV –

答

你不能得到FOV，它不是API https://developers.google.com/maps/documentation/javascript/3.exp/reference

由于anatoly.sukhanov张贴在，你可以找到计算它在这一问题的方式已经要求对SO how can I determine the Field of View a street view panorama map is using
