opencv 增强现实（一）：特征点检测
1 import cv2 as cv 2 import numpy as np 3 4 5 def draw_keypoints(img, keypoints): 6 for kp in keypoints: 7 x, y = kp.pt 8 cv.circle(img, (int(x), int(y)), 2, (0, 255, 0)) 9 10 11 img = cv.imread('D:/image/AR/moon.png') 12 gray = cv.cvtColor(img, cv.COLOR_BGR2GRAY) 13 # 启动orb探测器 14 detector = cv.ORB_create() 15 16 kp, des = detector.detectAndCompute(gray, None) 17 draw_keypoints(img=img, keypoints=kp) 18 cv.imshow('moon', img) 19 cv.waitKey(0)
之前用cv.drawKeypoints()报错，好像是版本问题，自定义一个函数来替换
