我不知道到底是什麼錯,但我想不出它在所有...的Python - 獲取從GPS經度和緯度的總距離
所以我有這樣的代碼:
from model.Formulas import Formulas
f = open("coords_data.txt", "r")
line1 = f.readline()
line2 = f.readline()
orig = line1.split(';')
dest = line2.split(';')
origin = (orig[0] + ", " + orig[1].strip("\n"))
destination = (dest[0] + ", " + dest[1].strip("\n"))
print("Orig: " + str(origin))
print("Dest: " + str(destination))
total_dist = Formulas.calculateDistance(str(origin), str(destination))
# Formulas.calculateDistance()
然後導入代碼是這樣的:
import math
class Formulas:
# 3959 # radius of the great circle in miles...some algorithms use 3956
# 6371 # radius in kilometers...some algorithms use 6367
# 3959 * 5280 # radius in feet
# 6371 * 1000 # radius in meters
@staticmethod
def calculateDistance(origin, destination, rounding=0):
lat1, lon1 = origin
lat2, lon2 = destination
radius = 6371 # km
dlat = math.radians(lat2 - lat1)
dlon = math.radians(lon2 - lon1)
a = math.sin(dlat/2) * math.sin(dlat/2) + math.cos(math.radians(lat1)) * math.cos(math.radians(lat2)) * math.sin(dlon/2) * math.sin(dlon/2)
c = 2 * math.atan2(math.sqrt(a), math.sqrt(1 - a))
d = radius * c
return round(d, rounding)
所以現在我想從座標的大名單(5057線),以獲得有確切的總距離。所以它需要計算所有距離之間的差異並返回一個大數字(例如150km)。
我得到的錯誤是:
ValueError: too many values to unpack (expected 2)
在文件看起來像這樣的座標:
5114.8268;00457.9847
5114.8271;00457.9845

現在是在一個文件,但這個數據將被存儲在數據庫中。
我該如何解決這個問題?我該如何擺脫這個錯誤?
什麼錯誤?你能否給出一些簡單的輸入/輸出與預期輸出的例子。 – Scheme
