Problems solved by technology

[0006] For the above-mentioned prior art, the technical problem to be solved by the present invention is: the existing mainstream WEB browsers include IE, Chrome, Firefox, etc., which support a very limited number of video encoding formats and have differences. Although the video decoding plug-in can solve the problem that the WEB browser does not support the video encoding format, most of the cases are limited to IE, and there are often difficulties and problems in the distribution and deployment of the video decoding plug-in

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] A method for browsing video images returned by a front-end camera through client access, comprising the following steps:

[0023] ①The monitoring client starts the browsing operation of the video image of a certain camera, and the browser logs in the front-end camera device through the HTTP protocol, and sets the frame rate parameters of the video image playback;

[0024] ②Send a capture picture request through the HTTP protocol GET or POST command;

[0025] ③Wait for the camera to complete the response of a frame of picture capture, and the picture file is stored in a certain path inside the camera device in JPG, GIF, PNG format;

[0026] ④The monitoring client updates the picture file information to under the element element to overwrite and update the previous image;

[0027] ⑤The browser communicates with the WEB ...

Abstract

The invention discloses a method for visiting and browsing a video image transmitted by a front end camera by using a client end. The video image transmitted by the front monitoring camera is visited and browsed in a plug-free mode through a WEB browser on the client end. The method can be operated under various operating systems and various terminal devices without installing and downloading a video decoding plug matched with a camera device, so that the convenience is brought for software issuing, version updating and user use. The method is suitable for mainstream WEB browsers such as IE (Internet Explorer), Chrome, Firefox and UCWEB (You Can Web) for PC (Personal Computer) and mobile terminals, effectively solves the problems of type limit and various compatibilities of decoding display of the video image of the camera to the user terminal, and maximally meets the demand of monitoring the video image under various complex application environments in an actual use process.

Description

technical field [0001] The invention relates to the technical field of video image monitoring, in particular to a method for using a client to access and browse a video image returned by a front-end camera. Background technique [0002] High-voltage transmission lines are the lifeline of power transmission. Early detection of the operation status of transmission lines was mainly done manually. This method has low efficiency, high cost, and heavy workload. With the development of information technology, sensor technology, communication technology, and new energy technology With continuous development, the automation of transmission line status detection is getting higher and higher, and finally a series of online monitoring systems with mature technologies and different emphases have been formed, which can comprehensively monitor the operation of transmission lines remotely, including pollution, wind swing, icing, etc. , stress and snow accumulation. Transmission line remote...
