AttributeError: module 'cv2.aruco' has no attribute 'drawFrameAxes'

I am working with VSCode 1.68.1, Ubuntu 20.04 I am following link (https://programming.vip/docs/3d-pose-estimation-using-aruco-tag-in-python.html) to achieve pose estimation for aruco marker

But I am getting below error: aruco.drawFrameAxes(dst1, mtx, dist, rvec[i, :, :], tvec[i, :, :],0.03) AttributeError: module 'cv2.aruco' has no attribute 'drawFrameAxes'

  • I tried using aruco.drawaxis as well, same error
  • Also tried uninstall opencv-python, uninstall opencv-contrib-python, then pip3 install opencv-python & pip3 install opencv-contrib-python, same error
Solution

  • drawFrameAxes is an independent module available in OpenCV. It isn't found within aruco package.

    The command: help(cv2.drawFrameAxes) gives you all the details you need regarding its usage and parameters.

    Try the following in your code:

    result_img = cv2.drawFrameAxes(dst1, mtx, dist, rvec[i, :, :], tvec[i, :, :],0.03)
