Detect rust using color segmentation Hi, I wanted to detect rust inside a pipe by creating suitable boundary condition.

Detect rust using color segmentation Hi, I wanted to detect rust inside a pipe by creating suitable boundary condition.

Hi, I'm able to get pose of all the detected markers but i'm not able to display the pose of each marker respectively on the image.

        for i in range(0, self.ids.size):
            #print(self.tvecs[i][0][2])
            cv_image=aruco.drawAxis(cv_image, camera_matrix, camera_distortion, self.rvecs[i], self.tvecs[i], 10)
            #str_position = "trans"%((self.tvecs[i][0]))

            str_position = "MARKER Position x=%4.0f  y=%4.0f  z=%4.0f"%(self.tvecs[i][0][0], self.tvecs[i][0][1], self.tvecs[i][0][2])
            #cv2.putText(cv_image, str_position, (0, 100), font, 1, (0, 255, 0), 2, cv2.LINE_AA)
            cv2.putText(cv_image, "{:.2f}".format(str_position), (0,100), font, 4,(255,255,255), 2, cv2.LINE_AA)

        #print(i)
        cv2.imshow("Image window", cv_image)
        cv2.waitKey(1)

So, anybody knows how to get the respective (x,y) position of the detected markers and then use cv2.putText?

Ahh, it works. Just changed a bit while doing cv2.putText.Have to play with offset only now..Thanks alot. pt =np.array(

Ahh, it works. Just changed a bit while doing cv2.putText. pt =np.array([[-12, -12, 0]], dtype=np.float) #for

On printing the imgpts i get ('Image points', (array([[[ 363.90325111, 151.41181538]]]), array([[ 0.00000000e+00,
