How to extract object orientation from video stream (Webcam)

I found

Thanks, Avishai

You will probably need library like opencv to get orientation information from the image. You can apply threshold after converting this image to grayscale and extract contour of the image. After that you need to follow something like below pattern to get orientation. Very easy, just a little bit search you can find a lot of similar examples as well.

rectangle_for_angle = cv2.minAreaRect(cntrs[0])
angle = rectangle_for_angle[-1]
rect_points = cv2.boxPoints(rectangle_for_angle)
rect_points_result = np.int0(rect_points)
#You can also draw rotated image
cv2.drawContours(image,[rect_points_result],0,(0,0,255),2)
