Trying to convert the below opencv python code to mojolang:
import cv2 as cvcap = cv.VideoCapture(0)if not cap.isOpened(): print("Cannot open camera") exit()while True: # Capture frame-by-frame ret, frame = cap.read() # if frame is read correctly ret is True if not ret: print("Can't receive frame (stream end?). Exiting ...") break # Our operations on the frame come here gray = cv.cvtColor(frame, cv.COLOR_BGR2GRAY) # Display the resulting frame cv.imshow('frame', gray) if cv.waitKey(1) == ord('q'): break# When everything done, release the capturecap.release()cv.destroyAllWindows()
import cv2 as cvcap = cv.VideoCapture(0)if not cap.isOpened(): print("Cannot open camera") exit()while True: # Capture frame-by-frame ret, frame = cap.read() # if frame is read correctly ret is True if not ret: print("Can't receive frame (stream end?). Exiting ...") break # Our operations on the frame come here gray = cv.cvtColor(frame, cv.COLOR_BGR2GRAY) # Display the resulting frame cv.imshow('frame', gray) if cv.waitKey(1) == ord('q'): break# When everything done, release the capturecap.release()cv.destroyAllWindows()
So, I wrote the below:
from python import Pythondef main(): # This is equivalent to Python's `import numpy as np` cv = Python.import_module("cv2") cap = cv.VideoCapture(0) if not cap.isOpened(): print("Cannot open camera") # exit() while True: # Capture frame-by-frame var ret, frame = cap.read() # I get the error here # if frame is read correctly ret is True if not ret: print("Can't receive frame (stream end?). Exiting ...") break # Our operations on the frame come here gray = cv.cvtColor(frame, cv.COLOR_BGR2GRAY) # Display the resulting frame cv.imshow('frame', gray) if cv.waitKey(1) == ord('q'): break # When everything done, release the capture cap.release() cv.destroyAllWindows()
from python import Pythondef main(): # This is equivalent to Python's `import numpy as np` cv = Python.import_module("cv2") cap = cv.VideoCapture(0) if not cap.isOpened(): print("Cannot open camera") # exit() while True: # Capture frame-by-frame var ret, frame = cap.read() # I get the error here # if frame is read correctly ret is True if not ret: print("Can't receive frame (stream end?). Exiting ...") break # Our operations on the frame come here gray = cv.cvtColor(frame, cv.COLOR_BGR2GRAY) # Display the resulting frame cv.imshow('frame', gray) if cv.waitKey(1) == ord('q'): break # When everything done, release the capture cap.release() cv.destroyAllWindows()
I got the error:
declaration must have either a type or an initializer
