Description

ABSTRACT

Raspberry Pi has mostly used hardware to interface/working with the camera-based application. Mainly for Open CV (Open Computer Vision) based applications. As the Raspberry Pi beginner, without USB camera, we can also use our mobile camera to capture an image to process in Raspberry Pi using IP cam. So that USB camera is not needed, with also high resolution. But frame processing will be a little bit slow when compared to USB camera. The mobile which we gonna uses the camera should be connected with the same network at which the Raspberry Pi is connected so that it acts as Local IP to work on IP camera.

url=["http://192.168.1.6:8080/shot.jpg","http://192.168.1.65:8080/shot.jpg"] #if we use multiple IP camera mobile
while True:
    for i in url:
        imgPath=urllib.urlopen(i)
        imgNp=np.array(bytearray(imgPath.read()),dtype=np.uint8)
        img=cv2.imdecode(imgNp,-1)
	cv2.imwrite('champ.jpg',img)
