部署环境
由于实验室只有无线网没有有线网，在这里依靠wifi路由器做出一个有线网。
wifi路由器根据wifi配置有线网
ip 192.168.113.17掩码 255.255.255.0网关192.168.113.254DNS 8.8.8.8
在这里是网络已经可以联通。
此时摄像头默认的ip地址是192.168.1.64，我自己将其该为192.168.114.64，这里其实可以不改
修改本地网口ip使其在一个网段，但不要用64
此时上面为wifi路由器提供的网，下面为摄像头的网，如果把wifi路由器网关闭，处于断网状态，运行下方代码
运行代码
import cv2import timeimport numpy as npuser, pwd, ip, channel = "admin", "passward", "192.168.114.64", 1video_stream_path = "rtsp://%s:%s@%s//Streaming/Channels/%d" % (user, pwd, ip, channel) # HIKIVISION new version video = cv2.VideoCapture(video_stream_path)l_used_time = []fps = 0while True:s = time.time()ret, frame = video.read()# print(ret)# image = cv2.resize(frame, (416, 416))# image = cv2.cvtColor(image, cv2.COLOR_BGR2RGB)# cv2.imshow("results", image)cv2.putText(frame, text='FPS: {}'.format(fps), org=(3, 15), fontFace=cv2.FONT_HERSHEY_SIMPLEX,fontScale=0.50, color=(255, 0, 0), thickness=2)cv2.imshow("results", frame)cv2.waitKey(5)used_time = time.time() - sl_used_time.append(used_time)if len(l_used_time) > 10:l_used_time.pop(0)fps = int(1 / np.mean(l_used_time))
可以跑通，但网线连上后就不能正常运行，这是由于连上路由器后会从路由器搜寻局域网内的ip而不是本地的。
如果要想联网还可以运行，可以把网线接入wifi路由器，此时要修改摄像头ip地址与路由器一个网段。
