Hello everyone, I am developing one computer vision application using OpenCV, C++, Cvblobs etc. I want to inspect one connector part having 6 pins. The goal is to detect the pins accurately. I am attaching one image for the pins and what I want to detect. Any help will be really appreciated.
Here is code:
#!/usr/bin/python37
#OpenCV 4.1.2; Raspberry pi 3b/4
#Date: 20th December, 2019
import cv2 as cv
img = cv.imread('pad.jpg')
img = cv.resize(img, (640, 732))
gray = cv.cvtColor(img, cv.COLOR_BGR2GRAY)
edges = cv.Canny(gray, 331, 999)
contours, _ = cv.findContours(edges.copy(), cv.RETR_EXTERNAL, cv.CHAIN_APPROX_SIMPLE)
for cnt in contours:
area = cv.contourArea(cnt)
peri = cv.arcLength(cnt, True)
approx = cv.approxPolyDP(cnt, 0.19*peri, True)
if area > 2 and len(approx) == 2:
cv.drawContours(img, [approx], -1, (0, 255, 0), 3)
cv.imwrite('solder_pads1.jpg', img)
cv.imshow('Image edges', edges)
cv.imshow('Image', img)
cv.waitKey(0)
Output:

Go back to your first comment and click image.
