[Solved] Reduce Blurring/Warping of image after repeated warpAffine

Public forum Technical questions

My code uses input from a rotary encoder connected to a Rapsberry Pi send over TCP:

    num_rows, num_cols = img.shape[:2]   
        
    data = s.recv(BUFFER_SIZE)
    speed = data.decode("utf-8")
    print("Speed = ", speed)
        
    translation_matrix = np.float32([ [1,0,np.float32(speed)], [0,1,0] ])
    img = cv2.warpAffine(img, translation_matrix, (num_cols, num_rows))

I use this input to make a translation matrix so that i can shift my image according the input from the encoder.

My initial Image looks like this:

Initial
Initial.png708×290 2.26 KB

After a few warpAffines it looks like this:

Warped

Is there a way to reduce the blurring/warping of the image while still being able to move it in a nice way

Apparently this is due to using floats inside the translation matrix, converting it to an integer works:

translation_matrix = np.float32([ [1,0,int(float(speed))], [0,1,0] ])
