【问题描述】:
我必须在 Pycharm 中测试代码(问题的底部),但我无法弄清楚如何在 Pycharm 中运行它而不出现此错误:
usage: color.py [-h] -i IMAGE
color.py: error: the following arguments are required: -i/--image
我知道如果我使用 Idle,我会编写以下代码:
/Users/syedrishad/Downloads/python-project-color-detection/color_detection.py -i
Users/syedrishad/Downloads/python-project-color-detection/colorpic.jpg
但我不知道如何在 Pycharm 上运行它 我使用的是 mac,出于某种原因,我总是必须输入完整的路径名,否则它不起作用。(如果这有所作为) 这个程序使它,所以如果我双击图像的一部分,它会显示确切的颜色名称。所有颜色名称都存储在这个文件中:
/Users/syedrishad/Downloads/python-project-color-detection/colors.csv
实际代码在这里:
import cv2
import numpy as np
import pandas as pd
import argparse
#Creating argument parser to take image path from command line
ap = argparse.ArgumentParser()
ap.add_argument('-i', '--image', required=True, help="Image Path")
args = vars(ap.parse_args())
img_path = args['image']
#Reading the image with opencv
img = cv2.imread(img_path)
#declaring global variables (are used later on)
clicked = False
r = g = b = xpos = ypos = 0
#Reading csv file with pandas and giving names to each column
index=["color","color_name","hex","R","G","B"]
csv = pd.read_csv('colors.csv', names=index, header=None)
#function to calculate minimum distance from all colors and get the most matching color
def getColorName(R,G,B):
minimum = 10000
for i in range(len(csv)):
d = abs(R- int(csv.loc[i,"R"])) + abs(G- int(csv.loc[i,"G"]))+ abs(B- int(csv.loc[i,"B"]))
if(d<=minimum):
minimum = d
cname = csv.loc[i,"color_name"]
return cname
#function to get x,y coordinates of mouse double click
def draw_function(event, x,y,flags,param):
if event == cv2.EVENT_LBUTTONDBLCLK:
global b,g,r,xpos,ypos, clicked
clicked = True
xpos = x
ypos = y
b,g,r = img[y,x]
b = int(b)
g = int(g)
r = int(r)
cv2.namedWindow('image')
cv2.setMouseCallback('image',draw_function)
while(1):
cv2.imshow("image",img)
if (clicked):
#cv2.rectangle(image, startpoint, endpoint, color, thickness)-1 fills entire rectangle
cv2.rectangle(img,(20,20), (750,60), (b,g,r), -1)
#Creating text string to display( Color name and RGB values )
text = getColorName(r,g,b) + ' R='+ str(r) + ' G='+ str(g) + ' B='+ str(b)
#cv2.putText(img,text,start,font(0-7),fontScale,color,thickness,lineType )
cv2.putText(img, text,(50,50),2,0.8,(255,255,255),2,cv2.LINE_AA)
#For very light colours we will display text in black colour
if(r+g+b>=600):
cv2.putText(img, text,(50,50),2,0.8,(0,0,0),2,cv2.LINE_AA)
clicked=False
#Break the loop when user hits 'esc' key
if cv2.waitKey(20) & 0xFF ==27:
break
cv2.destroyAllWindows()
如果你会跑步,请告诉我。我一直在寻找答案,但空手而归。

你可以破解代码来硬编码命令行参数,或者通过
Run > Edit Configurations...添加它们
