Question

任何人都知道如何提高fps，因为我从正常的opencv中获得了30 fps。如果我可以使其达到10或5 fps，那就太好了。因此，当我移动位置时，不会延迟显示摄像机图像的时间。因此视频将接近实时图像检测。

from flask import Flask, render_template, Response
import cv2

app = Flask(__name__)
camera = cv2.VideoCapture(0)
fps = camera.get(cv2.CAP_PROP_FPS)

@app.route('/')
def index():
    """Load template to index"""
    return render_template('index.html')

def load():
    """Load Image from Camera"""
    while True:
        success, frame = camera.read()

        # resize to 800x600, 640x480
        frame_width_fx = 640
        frame_height_fy = 480
        frame = cv2.resize(frame, (frame_width_fx, frame_height_fy))

        print(fps)

        cv2.imwrite('read.jpg', frame)
        yield (b'--frame\r\n'b'Content-Type: image/jpeg\r\n\r\n' + open('read.jpg', 'rb').read() + b'\r\n')

@app.route('/video_feed')
def video_feed():
    return Response(load(), mimetype='multipart/x-mixed-replace; boundary=frame')

if __name__ == '__main__':
    app.debug = True
    app.threaded = True
    app.run(use_reloader=False)

如何在python 3中的opencv中增加FPS？
