Witryna6 sie 2024 · Visualize: this step is a generic method of OpenCV to draw keypoints at their detected positions into an image, for debugging & verification. I used the optional flag DRAW_MATCHES_FLAGS_DRAW_RICH_KEYPOINTS. Instead of simply drawing a dot at each keypoint location, the method now additionally indicates the keypoint … Witryna11 lip 2024 · kpts1 = img.find_keypoints(max_keypoints=150, threshold=10, scale_factor=1.2) draw_keypoints(img, kpts1) else: # NOTE: When extracting keypoints to match the first descriptor, we use normalized=True to extract # keypoints from the first scale only, which will match one of the scales in the first descriptor.

Witryna7 wrz 2024 · I use cv2.drawKeypoints(image, keypoints, outImage, color, flags) in Python while showing the keypoints on the image. The color parameter is used in many examples as RGB value, i.e. (0, 0, 0) to (255, 255, 255), which is fixed for all keypoints. My problem is that I have a confidence value for each keypoint and I want to integrate … Witryna13 mar 2024 · 您可以使用函数cv2.drawKeypoints()来绘制角点,并通过参数设置角点的大小。具体来说,您可以通过设置参数"flags"为cv2.DRAW_MATCHES_FLAGS_DRAW_RICH_KEYPOINTS来绘制角点,并通过参数"radius"来设置角点的大小。 cindy phelps meller
