cv2画opencv logo
本篇博客主要介绍使用python中的cv2模块来绘制opencv的logo,下面是实现代码：
import numpy as np import cv2 import math r1 = 70 r2 = 30 ang = 60 d = 170 h = int(d / 2 * math.sqrt(3)) dot_red = (256, 128) dot_green = (int(dot_red[0] - d / 2), dot_red[1] + h) dot_blue = (int(dot_red[0] + d / 2), dot_red[1] + h) red = (0, 0, 255) green = (0, 255, 0) blue = (255, 0, 0) black = (0, 0, 0) full = -1 img = np.zeros((512, 512, 3), np.uint8) # img = np.ones((512, 512, 3), np.uint8) cv2.circle(img, dot_red, r1, red, full) cv2.circle(img, dot_green, r1, green, full) cv2.circle(img, dot_blue, r1, blue, full) cv2.circle(img, dot_red, r2, black, full) cv2.circle(img, dot_green, r2, black, full) cv2.circle(img, dot_blue, r2, black, full) cv2.ellipse(img, dot_red, (r1, r1), ang, 0, ang, black, full) cv2.ellipse(img, dot_green, (r1, r1), 360 - ang, 0, ang, black, full) cv2.ellipse(img, dot_blue, (r1, r1), 360 - 2 * ang, ang, 0, black, full) font = cv2.FONT_HERSHEY_SIMPLEX cv2.putText(img, text='OpenCV', org=(15, 450), fontFace=font, fontScale=4, color=(255, 255, 255), thickness=10)#text, cv2.imwrite("opencv_logo.png", img) cv2.imshow('opencv_log', img) cv2.waitKey(0) cv2.destroyAllWindows()
具体实现结果如下所示：
