代码

import cv2
import aircv as ac

# print circle_center_pos
def draw_circle(img, pos, circle_radius, color, line_width):
 cv2.circle(img, pos, circle_radius, color, line_width)
 cv2.imshow('objDetect', imsrc) 
 cv2.waitKey(0)
 cv2.destroyAllWindows()

if __name__ == "__main__":
 imsrc = ac.imread('bg.jpg')
 imobj = ac.imread('obj.png')

 # find the match position
 pos = ac.find_template(imsrc, imobj)

 circle_center_pos = pos['result']
 circle_radius = 50
 color = (0, 255, 0)
 line_width = 10

 # draw circle
 draw_circle(imsrc, circle_center_pos, circle_radius, color, line_width)
