我可以為你提供一些使用OpenCV進(jìn)行圖像處理的基本算子的示例代碼,但請(qǐng)注意,我無(wú)法提供完整的程序或代碼私鑰。
python復(fù)制代碼import cv2 import numpy as np image = cv2.imread('image.jpg', cv2.IMREAD_GRAYSCALE) edges = cv2.Canny(image, 100, 200) cv2.imshow('Edges', edges) cv2.waitKey(0) cv2.destroyAllWindows()
圓檢測(cè)(使用Hough變換):
python復(fù)制代碼import cv2 import numpy as np image = cv2.imread('image.jpg', cv2.IMREAD_GRAYSCALE) edges = cv2.Canny(image, 100, 200) circles = cv2.HoughCircles(edges, cv2.HOUGH_GRADIENT, 1, 20, param1=50, param2=30, minRadius=0, maxRadius=0) circles = np.uint16(np.around(circles)) for i in circles[0, :]: cv2.circle(image, (i[0], i[1]), i[2], (0, 255, 0), 2) cv2.imshow('Detected Circles', image) cv2.waitKey(0) cv2.destroyAllWindows()
模板匹配:
python復(fù)制代碼import cv2 import numpy as np image = cv2.imread('image.jpg', cv2.IMREAD_GRAYSCALE) template = cv2.imread('template.jpg', cv2.IMREAD_GRAYSCALE) w, h = template.shape[::-1] result = cv2.matchTemplate(image, template, cv2.TM_CCOEFF_NORMED) threshold = 0.8 loc = np.where(result >= threshold) for pt in zip(*loc[::-1]): cv2.rectangle(image, pt, (pt[0] + w, pt[1] + h), (0, 0, 255), 2) cv2.imshow('Detected Template', image) cv2.waitKey(0) cv2.destroyAllWindows()
請(qǐng)注意,這些代碼示例是用于演示目的,可能需要根據(jù)具體情況進(jìn)行調(diào)整。另外,請(qǐng)確保在使用OpenCV之前安裝了必要的庫(kù)。你可以通過(guò)pip安裝OpenCV:pip install opencv-python。
