如何使用 TimestampedGeoJson 和 folium 为 GPS 点创建绘图动画？

如何解决如何使用 TimestampedGeoJson 和 folium 为 GPS 点创建绘图动画？

这是我的代码：

import folium
from folium import plugins
import os
import json
import natsort

def plot_app_gps():
    arg_file = open('args.json','r+')
    args = json.load(arg_file)

    loc_files = [i for i in natsort.natsorted(os.listdir(os.path.join(args['imgs_loc'],'location_data')))]
    lat,long = 0,0
    for loc_file in loc_files:
        loc_json = json.load(open(os.path.join(args['imgs_loc'],'location_data',loc_file),'r+'))
        lat += round(float(loc_json['latitude']),8)
        long += round(float(loc_json['longitude']),8)

    # Create the map used to visualise the locations of the images.
    map_centre_lat = lat / len(loc_files)
    map_centre_lon = long / len(loc_files)

    my_map = folium.Map(location=[map_centre_lat,map_centre_lon],zoom_start=16,)

    # Draw a red circle on the centre of the map.
    folium.CircleMarker((map_centre_lat,map_centre_lon),radius=7,color='#FF0000',fill_color='#0080bb').add_to(my_map)

    features = []
    import datetime

    for loc_file in loc_files:
        loc_json = json.load(open(os.path.join(args['imgs_loc'],'r+'))
        '1970-01-01 00:00:00'
        feature = {
            'type': 'Feature','geometry': {
                'type': 'Point','coordinates': [float(loc_json['latitude']),float(loc_json['longitude'])]
            },'properties': {
                'time': str(datetime.datetime.Now() + datetime.timedelta(0,1)).split('.')[0],'style': {'color': ''},'icon': 'circle','iconstyle': {
                    'fillOpacity': 0.8,'stroke': 'true','radius': 5
                }
            }
        }
        features.append(feature)

    plugins.TimestampedGeoJson(features,period='PT1H',duration='PT1H',transition_time=1000,auto_play=True).add_to(my_map)

    my_map.save(os.path.join(args['root_dir'],'map_with_gps_locations.html'))

但是我没有看到绘图点的动画？左下角的时间条只是停留在开始时间，从不打扰移动。我仅使用 folium 在地图上绘制了所有 GPS 坐标，它们是正确的。现在，我想为绘图过程设置动画，但 TimestampedGeoJson 不起作用。

解决方法

我最终使用以下代码使其工作：

import folium
from folium import plugins
import os
import json
import natsort

def plot_app_gps():
    arg_file = open('args.json','r+')
    args = json.load(arg_file)

    loc_files = [i for i in natsort.natsorted(os.listdir(os.path.join(args['imgs_loc'],'location_data')))]
    lat,long = 0,0
    for loc_file in loc_files:
        loc_json = json.load(open(os.path.join(args['imgs_loc'],'location_data',loc_file),'r+'))
        lat += round(float(loc_json['latitude']),8)
        long += round(float(loc_json['longitude']),8)

    # Create the map used to visualise the locations of the images.
    map_centre_lat = lat / len(loc_files)
    map_centre_lon = long / len(loc_files)

    my_map = folium.Map(location=[map_centre_lat,map_centre_lon],zoom_start=16,)

    # Draw a red circle on the centre of the map.
    folium.CircleMarker((map_centre_lat,map_centre_lon),radius=7,color='#FF0000',fill_color='#0080bb').add_to(my_map)

    features = []
    import datetime

    current_time = datetime.datetime.now()
    extra_seconds = 0
    for loc_file in loc_files:
        loc_json = json.load(open(os.path.join(args['imgs_loc'],'r+'))
        now = str(current_time + datetime.timedelta(0,60*extra_seconds)).split('.')[0]
        feature = {
            'type': 'Feature','geometry': {
                'type': 'Point','coordinates': [float(loc_json['longitude']),float(loc_json['latitude'])]
            },'properties': {
                'time': now,'style': {'color': ''},'icon': 'circle','iconstyle': {
                    'fillColor': '#0000FF','fillOpacity': 0.8,'stroke': 'true','radius': 5
                }
            }
        }
        features.append(feature)
        extra_seconds += 1

    plugins.TimestampedGeoJson(features,period='PT1H',duration='PT1M',transition_time=1000,auto_play=True).add_to(my_map)

    my_map.save(os.path.join(args['root_dir'],'map_with_gps_locations.html'))
