Detailed Description
The following description is presented to disclose the invention so as to enable any person skilled in the relevant art to practice the invention. The embodiments described below are intended to be examples only, and other obvious modifications will occur to those skilled in the relevant art and are within the scope of the invention.
Embodiments of the present invention will be described in detail below with reference to fig. 1-2.
In one embodiment, as shown in figure 1,
a network CAMERA localization system applied in television equipment comprises a detection module, a data acquisition module, a data processing module and a CAMERA application,
A) the detection module is accessed to a network and used for retrieving a network camera in the network in real time and acquiring a video streaming URL (uniform resource locator) of the network camera;
the television searches whether the Network camera equipment is accessed in the current Network or not through an ONVIF protocol, wherein the ONVIF protocol is an Open industry standard established by an Open Network Video Interface Forum. The purpose of this interface standard is to ensure the interoperability of network video products produced by different manufacturers. The network camera ONVIF detection module of the television periodically sends UDP multicast signals of the local network and then receives response data sent back by the network video equipment of each IP address. And then the network camera detection module analyzes the response data to acquire the information of the network video equipment, so that the url of the video streaming transmission of the network camera required to be used can be finally obtained. Through the url, the video stream recorded by the network camera in real time can be acquired.
B) The data acquisition module is connected with the detection module and is connected with the url through the detection module to acquire video data;
after the video stream url is obtained, the detection module transmits the url to the data acquisition module, and then the network camera is connected to acquire video data of rtsp. Some webcams transmit video and audio together, so demultiplexing is required to separate the video and audio to obtain separate video stream data.
C) The data processing module is connected with the data acquisition module and is used for decoding video data and carrying out processing such as image format conversion or scaling to ensure that the video data acquired by the network camera is consistent with the data output format of the USB camera;
the method comprises the steps of obtaining compressed and coded network camera video stream data, mostly adopting an h264 or h265 compression coding mode for network cameras, then decoding separated video data to obtain frame number images capable of being directly displayed, and mostly adopting YUV or RGB format for images.
The USB camera on the television outputs YVYU format pictures sampled by AD conversion, and pictures decoded and generated after acquiring the network camera are generally YUV420 format, so format conversion needs to be performed on the decoded pictures to generate YVYU format pictures as the output format of the USB camera. In addition, the width and height of the picture required by the CAMERA application may be different from the width and height of the picture obtained by the network CAMERA, and the picture needs to be zoomed to generate the picture with the same width and height required by the CAMERA application.
D) The CAMERA application is provided with a CAMERA interface, CAMERA equipment is opened and CAMERA data is acquired through the CAMERA interface, the flow and operation of the network CAMERA are consistent with those of the USB CAMERA, and the network CAMERA replaces the USB or a common CAMERA;
the CAMERA equipment is opened and CAMERA data are obtained through the standard CAMERA interface by the CAMERA application, so that the operation of the network CAMERA is required to be connected with the CAMERA through the CAMERA interface, the operation of the network CAMERA is accessed into each interface of the CAMERA one by one, the operation of the network CAMERA is completely the same as that of the USB CAMERA in the process of operating the network CAMERA, and the universality and operability of the CAMERA are improved.
The CAMERA application acquires and processes the network CAMERA data according to a normal flow;
after the standard CAMERA interface is connected, the CAMERA application can operate the network CAMERA and the USB CAMERA as a device, such as photographing, recording, previewing and the like. Therefore, the network camera is used for replacing the traditional camera, the application range of the network camera is wider, and the operation is more convenient.
In another embodiment, as shown in figure 2,
a method for localizing a network CAMERA obtains video data of the network CAMERA by retrieving the network CAMERA on a network, then decodes the video data and converts the video data into video preview data with the same output format as a USB CAMERA, and the video preview data is provided for a CAMERA application, so that the network CAMERA can be used for replacing the USB CAMERA, the effect of widening the use scene of the CAMERA is achieved, and the interactive use experience of a user is improved.
The method comprises the following specific steps:
firstly, a user sends a CAMERA query command through a CAMERA application, a network CAMERA in a network is searched in real time, and a url of a network CAMERA video stream is obtained;
connecting the url, acquiring video data, separating audio and video data in the url, and extracting video data after coding and compression;
decoding the acquired coded video data to generate a YUV or RGB image which can be directly used for display;
step four, according to the width, height and pixel format of the picture set by the CAMERA application, the width, height and pixel format of the generated image frame are converted;
and step five, a standard CAMERA interface is connected in a butt joint mode, the converted image data is transmitted to the needed CAMERA application through a data transmission channel of the standard CAMERA, and data transmission is completed.
By the method, the network CAMERA is simulated to be CAMERA to realize the function of common CAMERA in a mode that the network CAMERA is connected with the CAMERA interface in a butt joint mode, the connection between the network CAMERA and the television is carried out, the defect that the common CAMERA is limited by the length of a cable is overcome, the use scene of the television CAMERA is widened, and the interactive use experience of a user is improved.
