python当前时间命名图片 python+opencv保存图片以系统时间命名怎么敲？

该楼层疑似违规已被系统折叠隐藏此楼查看此楼

mport numpy as np

import cv2

import time

cap = cv2.VideoCapture(0)

time = time.localtime(time.time())

color = (0,255,0)

line_width = 3

radius = 100

point = (0,0)

def click(event, x, y, flags, param):

global point, pressed

if event == cv2.EVENT_LBUTTONDOWN:

# 如果点击窗口，则打印鼠标点击的相对坐标

print(time.tm_hour,time.tm_min,time.tm_sec,x,y)

name = time.tm_hour,time.tm_min,time.tm_sec

print(name)

frame = cv2.imread(im_name)

cv2.imwrite('D/:' + name, frame)

point = (x,y)

cv2.namedWindow("Frame")

cv2.setMouseCallback("Frame",click)

while(True):

ret, frame = cap.read()

frame = cv2.resize(frame, (0,0), fx=1.3,fy=1.3)

cv2.circle(frame, point, radius, color, line_width)

cv2.imshow("Frame",frame)

ch = cv2.waitKey(1)

if ch & 0xFF == ord('q'):

break

cap.release()

cv2.destroyAllWindows()

这里只能保存自己设置命名的时间
