Hi, I'm just beginner to the python and opencv. Based on this Template Matching, the following code is detect multiple object:
import numpy as np
import cv2
img = cv2.imread("C:\\xampp\\htdocs\\IRR\\images\\Try.jpg")
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
template = cv2.imread("C:\\xampp\\htdocs\\IRR\\Scanner\\RM1FS.jpg",0)
res = cv2.matchTemplate(gray, template, cv2.TM_SQDIFF_NORMED)
min_val, max_val, min_loc, max_loc = cv2.minMaxLoc(res)
min_thresh = (min_val + 1e-6) * 1.5
match_locations = np.where(res<=min_thresh)
w, h = template.shape[::-1]
for (x, y) in zip(match_locations[1], match_locations[0]):
cv2.rectangle(img, (x, y), (x+w, y+h), [0,255,255], 2)
cv2.namedWindow('image', cv2.WINDOW_NORMAL)
cv2.imshow('', img)
cv2.waitKey(0)
So Try.jpg is
and RM1FS.jpg is
But i get the result after run the code is :
Can anyone share me ideas how to get the yellow square that only square up the RM 1 corner place with thin yellow line?
