How to get a picture of a place from google maps or places API

问题


I'm using Google Places API to retrieve data about places, but couldn't find how to get a picture of that place, Google Places API just provides icon which is not the same. I need the photo you get when you search for a place in Google Maps in a web browser for example. There is usually more pictures from Panoramio, but Panoramio API can only search for pictures by location and not by a particular restaurant or hotel name for example. Any ideas?


回答1:


The Places API will give you the coordinates (latitude and longitude) in the place detail response; you can then send the coordinates to the Panoramio API.

For example (drawing from examples in the API docs):

https://maps.googleapis.com/maps/api/place/details/json?reference=<big long key for place>&sensor=true&key=AIzaSyAiFpFd85eMtfbvmVNEYuNds5TEF9FjIPI

Response:

{
  "html_attributions" : [],
  "result" : {
    "address_components" : [
      {
        "long_name" : "48",
        "short_name" : "48",
        "types" : [ "street_number" ]
      },
      {
        "long_name" : "Pirrama Road",
        "short_name" : "Pirrama Road",
        "types" : [ "route" ]
      },
      {
        "long_name" : "Pyrmont",
        "short_name" : "Pyrmont",
        "types" : [ "locality", "political" ]
      },
      {
        "long_name" : "NSW",
        "short_name" : "NSW",
        "types" : [ "administrative_area_level_1", "political" ]
      },
      {
        "long_name" : "AU",
        "short_name" : "AU",
        "types" : [ "country", "political" ]
      },
      {
        "long_name" : "2009",
        "short_name" : "2009",
        "types" : [ "postal_code" ]
      }
    ],
    "formatted_address" : "5/48 Pirrama Road, Pyrmont NSW, Australia",
    "formatted_phone_number" : "(02) 9374 4000",
    "geometry" : {
      "location" : {
        "lat" : -33.8669710,
        "lng" : 151.1958750
      }
    },
    "icon" : "http://maps.gstatic.com/mapfiles/place_api/icons/generic_business-71.png",
    "id" : "4f89212bf76dde31f092cfc14d7506555d85b5c7",
    "international_phone_number" : "+61 2 9374 4000",
    "name" : "Google Sydney",
    "rating" : 4.60,
    "reference" : "CnRlAAAAAfV6JIqSzL8Cf4VnXn0EaI1d5k3IPhdkEonq0MxiUbQFFSVuptVbXbNH4mrevb0bc7G8yWqTUv76i4KTuO_Wf3OrRHjCJJwzQ0mNLjbYGSVqy2eqyrgOUkl6S_sJfTbHzWZYrfPy7KZaet0mM5S6thIQJYuy5v_JD--ZxXEJLWTQRRoU5UaciXBBo89K-bce18Ii9RsEIws",
    "types" : [ "store", "establishment" ],
    "url" : "http://maps.google.com/maps/place?cid=10281119596374313554",
    "vicinity" : "5/48 Pirrama Road, Pyrmont",
    "website" : "http://www.google.com.au/"
  },
  "status" : "OK"
}

We can see that the coordinates are "location" : { "lat" : -33.8669710, "lng" : 151.1958750 }

Then we can send a request to Panoramio, inserting the coordinates, plus a little wiggle room on either side (I did +/- 0.002 degrees, a shape 200 m x 200 m square at the equator, generally smaller). http://www.panoramio.com/map/get_panoramas.php?set=public&from=0&to=20&minx=-33.868&miny=151.193&maxx=-33.864&maxy=151.197&size=medium&mapfilter=true

You may need to do some filtering of the responses to get the closest photo, but this should give you something to work with.

The Places API just added the ability to request photos directly in the API: https://developers.google.com/maps/documentation/javascript/places#places_photos




回答3:


The Places API now supports the return of one place photo if available for a Place Search request and up to ten place photos for a Place Details request.

If a photos array is returned with your request, you can pass the photo_reference from a contained photo object to a Place Photo request with the maxheight and/or maxwidth, sensor and key parameters:

https://maps.googleapis.com/maps/api/place/photo?maxwidth=400&photoreference=CnRvAAAAwMpdHeWlXl-lH0vp7lez4znKPIWSWvgvZFISdKx45AwJVP1Qp37YOrH7sqHMJ8C-vBDC546decipPHchJhHZL94RcTUfPa1jWzo-rSHaTlbNtjh-N68RkcToUCuY9v2HNpo5mziqkir37WU8FJEqVBIQ4k938TI3e7bf8xq-uwDZcxoUbO_ZJzPxremiQurAYzCTwRhE_V0&sensor=false&key=AddYourOwnKeyHere

Please see the documentation for more details.

  1. First get the photo_reference from the response:

     var photoRef;
     if (data.results[i].photos && Array.isArray(data.results[i].photos)) {
     photoRef = data.results[i].photos[0].photo_reference;
     }
    
  2. Use the Google Photos API endpoint to GET the place photo/picture:

https://maps.googleapis.com/maps/api/place/photo?maxwidth=960&photoreference="+ photoRef +"&key=AIzaSyBp0cy7ti0z5MJMAwWiPMNvbJobmWYGyv4' alt=''/>
