Dronekit Python没有转到特定位置

Question

我在Python上有关于Dronekit的问题

我的项目是从Android应用程序接收GPS位置，然后将无人机发射到该位置，一切正常，但问题是无人机可以起飞，但无人机没有去那个位置（测试10次以上只能工作1次）

这是我的代码（我认为问题是GlobalRelative）

 # Import DroneKit-Python
from dronekit import connect, VehicleMode, LocationGlobalRelative
import time
import urllib2
import simplejson
import json
import requests


#Wait for json data
response = urllib2.urlopen("http://localhost:3000/posts")
data = simplejson.load(response)
print(data)
json_string = data[0]["Information"]

gps = json.loads(json_string)
x=gps['lat']
y=gps['lon']
r = requests.delete('http://localhost:3000/posts/1')
# Connect to the Vehicle.
print("Connecting")
vehicle = connect('com4', wait_ready=False, baud=57600)#; vehicle.wait_ready(True, timeout=300)
print("Connected")
# Get some vehicle attributes (state)
print "Get some vehicle attribute values:"
print " GPS: %s" % vehicle.gps_0
print " Battery: %s" % vehicle.battery
print " Last Heartbeat: %s" % vehicle.last_heartbeat
print " Is Armable?: %s" % vehicle.is_armable
print " System status: %s" % vehicle.system_status.state
print " Mode: %s" % vehicle.mode.name    # settable

# Takeoff Function
def arm_and_takeoff(tgt_altitude):
    print("Arming motors")

#   while not vehicle.is_armable:
#       time.sleep(1)

    vehicle.mode = VehicleMode("GUIDED")
    vehicle.armed = True

    print("Takeoff")
    vehicle.simple_takeoff(tgt_altitude)

    # wait reach tgt_altitude
    while True:
        altitude = vehicle.location.global_relative_frame.alt

        if altitude >= tgt_altitude -1:
            print("Altitude Reached")
            break

        time.sleep(1)

# Main
arm_and_takeoff(10)

# Speed
vehicle.airspeed = 7

# Go to wp
wp1 = LocationGlobalRelative(x, y, 10)

# Close vehicle object before exiting script

vehicle.mode = VehicleMode("RTL")
vehicle.close()


print("Completed")

或者，如果我无法解决此问题，我想使用MissionPlanner（我对其进行测试，并且可以正常工作），但是我想等待Phone的GPS定位，然后启动任务（每件事必须自动进行），我不知道如何绕过MissionPlanner

行： wp1 = LocationGlobalRelative(x, y, 10)仅将wp1变量分配给位置坐标。 您可以使用vehicle.simple_goto(wp1) 。 simple_goto是dronekit中的内置函数，用于命令车辆达到特定坐标，您可以在此处了解更多信息http://python.dronekit.io/automodule.html?highlight=simple_goto#dronekit.Vehicle.simple_goto
