How to get mapObject？I want to transfer point from gprs to lat&lng

[qianzhiheilv]

I get lat&lng from gprs,but it need to be transfer to lat&lng in map,I find a way to chang it

export function latLng2Point(latLng, map) {

    var topRight = map.getProjection().fromLatLngToPoint(map.getBounds().getNorthEast());
    var bottomLeft = map.getProjection().fromLatLngToPoint(map.getBounds().getSouthWest());
    var scale = Math.pow(2, map.getZoom());
    var worldPoint = map.getProjection().fromLatLngToPoint(latLng);
    return new google.maps.Point((worldPoint.x - bottomLeft.x) * scale, (worldPoint.y - topRight.y) * scale);
}

export function point2LatLng(point, map) {
    var topRight = map.getProjection().fromLatLngToPoint(map.getBounds().getNorthEast());
    var bottomLeft = map.getProjection().fromLatLngToPoint(map.getBounds().getSouthWest());
    var scale = Math.pow(2, map.getZoom());
    var worldPoint = new google.maps.Point(point.x / scale + bottomLeft.x, point.y / scale + topRight.y);
    return map.getProjection().fromPointToLatLng(worldPoint);
}

I need map object,I use refs to get mapObject,but it is not right.

          <gmap-map :center="center" :zoom="15" style="position: inherit; left: 10%; right: 10%; height:300px;width:300px;"  ref="googleMap">
                    <gmap-marker :key="i" v-for="(m,i) in markers" :position="m.position" :clickable="false" :draggable="false"></gmap-marker>
                </gmap-map>
            var point = {x:31.582610,y:118.445242};
            console.log(this.$point2LatLng(point,this.$refs.googleMap.$mapObject));

How can l get mapObject of google?Thank you very much.
