cv2.error: When the input arrays in add/subtract/multiply/divide functions have different types, the output array type must be explicitly specified in function "arithm_op"

cv2.addWeighted(image, 1, overlay, 0.3, 0)
-> cv2.addWeighted(image, 1, overlay, 0.3, 0, dtype=cv2.CV_64F)

 

cv2.addWeighted(image, 1, overlay, 0.3, 0, dtype=cv2.CV_64F)

 

이렇게 데이터 타입을 명시해주면 된다
