语音助手的图像捕捉

问题描述

我在为 Python 程序中的高效图像捕获器编写代码时遇到了一些困难我已经看到了捕获单个命令 opencv 普通图像捕获命令，但它们不起作用，所以任何人都可以帮助我。这些代码我已经用过了

import cv2 

key = cv2. waitKey(1)
webcam = cv2.VideoCapture(0)
while True:
    try:
        check,frame = webcam.read()
        print(check) #prints true as long as the webcam is running
        print(frame) #prints matrix values of each framecd 
        cv2.imshow("Capturing",frame)
        key = cv2.waitKey(1)
        if key == ord('s'): 
            cv2.imwrite(filename='saved_img.jpg',img=frame)
            webcam.release()
            img_new = cv2.imread('saved_img.jpg',cv2.IMREAD_GRAYSCALE)
            img_new = cv2.imshow("Captured Image",img_new)
            cv2.waitKey(1650)
            cv2.destroyAllWindows()
            print("Processing image...")
            img_ = cv2.imread('saved_img.jpg',cv2.IMREAD_ANYCOLOR)
            print("Converting RGB image to grayscale...")
            gray = cv2.cvtColor(img_,cv2.COLOR_BGR2GRAY)
            print("Converted RGB image to grayscale...")
            print("Resizing image to 28x28 scale...")
            img_ = cv2.resize(gray,(28,28))
            print("Resized...")
            img_resized = cv2.imwrite(filename='saved_img-final.jpg',img=img_)
            print("Image saved!")
        
            break
        elif key == ord('q'):
            print("Turning off camera.")
            webcam.release()
            print("Camera off.")
            print("Program ended.")
            cv2.destroyAllWindows()
            break
        
    except(KeyboardInterrupt):
        print("Turning off camera.")
        webcam.release()
        print("Camera off.")
        print("Program ended.")
        cv2.destroyAllWindows()
        break

和

from ecapture import ecapture as ec

ec.capture(0,"test","img.jpg")

还有opencv很多程序
