Problems solved by technology

At present, there are 18 railway bureaus in the country, and the number of cameras in the railway comprehensive video surveillance system of each railway bureau is about 10,000. With such a large number of cameras, if we only rely on manual inspection to check whether the pan / tilt of each camera is Available, it is bound to greatly increase the workload and complexity of manual detection, and the work efficiency is low

Embodiment Construction

[0011] The technical solutions of the present invention will be described in further detail below through specific implementation methods.

[0012] A method for judging the effectiveness of a video camera platform, comprising the following steps:

[0013] Step 1. Log in the encoder corresponding to the camera, obtain I-frame image data from the encoder channel connected to the camera, save it as a picture file, and mark it as the picture before the PTZ call, as an image template.

[0014] Step 2. Capture a piece of picture from the central area of ​​the picture before the cloud platform is called, and mark it as a comparison picture.

[0015] Step 3. Send a pan-tilt call command to the encoder channel corresponding to the camera, and then obtain I frame image data from the channel, save it as a picture file, and mark it as a picture after the pan-tilt call.

[0016] Step 4, image-matching the comparison picture and the picture after the cloud platform is called, that is, comp...

Abstract

The invention provides a video camera pan-tilt validity judgment method, which comprises the following steps: saving image data stored in a video camera before pan-tilt invoking as a picture and marking the picture as a picture before pan-tilt invoking; intercepting a block of picture from the central area of the picture before pan-tilt invoking, and marking the picture as a comparison picture; sending a control order to the pan-tilt, invoking the video camera, saving image data shot after video camera invoking as a picture and marking the picture as a picture after pan-tilt invoking; carrying out image matching on the comparison picture and the picture after pan-tilt invoking, i.e. comparing the image in the comparison picture with the image in the central area of the picture after pan-tilt invoking, judging the video camera pan-tilt to be valid if the two images are inconsistent, and judging the video camera pan-tilt to be invalid if the two images are consistent. The video camera pan-tilt validity judgment method has the advantages of simple method, strong practicability and high work efficiency, and is convenient to use.

Description

technical field [0001] The invention relates to a method for monitoring whether a camera is working normally, in particular to a method for judging the validity of a camera pan / tilt. Background technique [0002] The comprehensive railway video surveillance system is a video surveillance system built with networked and digital video surveillance technology and IP transmission mode, providing video information required by various railway business departments and information systems, and realizing network and video information resource sharing. At present, there are 18 railway bureaus in the country, and the number of cameras in the railway comprehensive video surveillance system of each railway bureau is about 10,000. With such a large number of cameras, if we only rely on manual inspection to check whether the pan / tilt of each camera is Available, it is bound to greatly increase the workload and complexity of manual detection, and the work efficiency is low. In order to sol...
