http://opencv24-python-tutorials.readthedocs.io/en/latest/py_tutorials/py_imgproc/py_template_matching/py_template_matching.html WebTemplate Matching is a method for searching and finding the location of a template image in a larger image. OpenCV comes with a function cv2.matchTemplate () for this purpose. It simply slides the template image over the input image (as in 2D convolution) and compares the template and patch of input image under the template image.

Web1 de out. de 2024 · The built-in template matching function of OpenCV is robust but only if you have positional invariance requirement. It fails if the object in the live footage rotates with respect to the master image. Another algorithm explored was feature-matching. This ticked all the boxes. It is positional, rotational, and scale-invariant.
