Embodiment 1

[0020] figure 1 It is a flowchart of an embodiment of the mobile video monitoring method of the present invention. Such as figure 1 As shown, this embodiment includes:

[0021] Step 102, collecting the video information of the current frame;

[0022] Step 104, carry out new information detection to the video information of current frame, judge whether it is new information frame; If yes, execute step 108; If not, return to step 102;

[0023] In this embodiment, the new information detection is mainly to compare the current frame with its adjacent frame images, and when the difference between the images of the two frames is greater than a preset threshold, it is determined that the current frame is a new information frame; Of course, according to actual needs, other methods can also be used for the detection of new information frames,

[0024] For example: to calculate: Wherein n represents the quantity of moving macroblocks in the current frame, and N represents the quan...

Embodiment 2

[0042] Preferably, in this embodiment, geographic location information is also associated with each frame of video information. It mainly includes the following steps:

[0043] After encoding the geographic location information corresponding to the current frame, geocoding data is obtained, and the geocoding data and video coding data are sent to the monitoring platform;

[0044] After the monitoring platform decodes the received geocoding data, it obtains the geographic information corresponding to the current frame.

[0045] Such as Figure 4 As shown, the encoding of geographic location information includes the following steps:

[0046] Geographic location information G corresponding to the current frame i and its predicted value Get the prediction error of the geographic location information

[0047] The prediction error e of the geographic location information i Entropy coded and predicted values It is transmitted to the monitoring platform through the channel....

Abstract

The invention discloses a mobile video monitoring method, a device and a system, wherein the mobile video monitoring method comprises the following steps of: A, carrying out new information detection on collected current frame video information; B, coding a new information frame when the new information frame exists and obtaining video coding data; and C, obtaining a current frame image after decoding the video coding data. The mobile video monitoring method, the device and the system have the advantages that the new information detection is carried out on the collected video information, thevideo information codes of the new information frame are uploaded only when the new information frame occurs, the coding rate is improved, the uploading data quantity is reduced, more images can be transmitted in a short time, in addition, useful video information can not be lost, and the monitoring effect is not influenced.

Description

technical field [0001] The invention relates to a digital video processing technology, in particular to a mobile video monitoring method, device and system. Background technique [0002] The urban public transportation system is an important subsystem of the urban socio-economic system. Its development level is an important symbol to measure the degree of modernization of the country, and it also reflects the comprehensive economic strength of the country, the development of the urban economy and the living standards of urban residents. As my country's urbanization continues to expand and the population continues to increase, the pressure on urban traffic has also increased. In recent years, the concept of intelligent transportation has begun to be recognized and accepted by people. The construction of my country's urban public transport system is still in its infancy, its management is relatively backward, and its level of informatization is not high. The establishment and...
