OpenCVの描画機能
OpenCVの描画機能こちらを動かしてみた。
import numpy as np import cv2 # Create a black image img = np.zeros((512,512,3), np.uint8) # Draw a diagonal blue line with thickness of 5 px img = cv2.line(img,(0,0),(511,511),(255,0,0),5) img = cv2.rectangle(img,(384,0),(510,128),(0,255,0),3) img = cv2.circle(img,(447,63), 63, (0,0,255), -1) img = cv2.ellipse(img,(256,256),(100,50),0,0,180,255,-1) pts = np.array([[10,5],[20,30],[70,20],[50,10]], np.int32) pts = pts.reshape((-1,1,2)) img = cv2.polylines(img,[pts],True,(0,255,255)) font = cv2.FONT_HERSHEY_SIMPLEX cv2.putText(img,'OpenCV',(10,500), font, 4,(255,255,255),2,cv2.LINE_AA) cv2.imshow('image',img) cv2.waitKey(0) cv2.destroyAllWindows()
