感谢博主——
这类东西真的是不是天天打,就是打过就忘。。

有志者事竟成,破釜沉舟,百二秦关终属楚。
苦心人天不负,卧薪尝胆,三千越甲可吞吴。
希望,在最后一年可以专心做自己喜欢的事情的本科生涯,不要留下遗憾。

OpenCV provides a function called `cv2.findContours()` that can be used to find the contours of a shape in an image. To find a specific shape model, you can first create a template of the shape you want to find. This can be done by drawing the shape on a blank image and saving it. Then, you can use the `cv2.matchTemplate()` function to match the template to the image and find the location of the shape. Here is an example code snippet for finding a circle shape model in an image: ```python import cv2 # Load the image img = cv2.imread('image.jpg') # Create a template of the circle shape template = cv2.imread('circle_template.jpg', cv2.IMREAD_GRAYSCALE) # Find the contours of the image _, contours, _ = cv2.findContours(img, cv2.RETR_TREE, cv2.CHAIN_APPROX_SIMPLE) # Loop through the contours and match the template for contour in contours: # Get the bounding box of the contour x, y, w, h = cv2.boundingRect(contour) # Crop the image to the bounding box roi = img[y:y+h, x:x+w] # Match the template to the ROI result = cv2.matchTemplate(roi, template, cv2.TM_CCOEFF_NORMED) # Set a threshold for the match result threshold = 0.7 # Find the location of the shape locations = np.where(result >= threshold) # Draw a rectangle around the shape for loc in zip(*locations[::-1]): cv2.rectangle(img, (x+loc[0], y+loc[1]), (x+loc[0]+w, y+loc[1]+h), (0, 0, 255), 2) # Display the image with the detected shape cv2.imshow('Detected shape', img) cv2.waitKey(0) cv2.destroyAllWindows() ``` Note that this is just one way to find a shape model in an image using OpenCV. Depending on the complexity of the shape, you may need to use more advanced techniques such as feature detection or machine learning.
