Information situation awareness and propagation management and control model based on node influence

The invention belongs to the field of social network analysis, and discloses an information situation awareness and propagation management and control model based on node influence. The model comprises a data acquisition module, a characteristic extraction module and an information situation awareness and propagation module, wherein the data acquisition module obtains source data from a social network, obtains the personal attribute, the historical behavior and the friend relationship of a node from the source data, and constructs an information propagation network; the characteristic extraction module independently extracts characteristics from two dimensions including a network dynamic attribute and an interaction dynamic attribute, and independently calculates corresponding factor functions; and the information situation awareness and propagation module constructs the information situation awareness and propagation management and control model on the basis of a mean-field theory, simulates an information propagation tendency, perceives an information diffusion tendency, captures the peak hour of information outburst, and mines a dynamic factor which drives the information to be propagated. By use of the method, the dynamics reason of the information propagation in an on-line social network can be effectively explained, an information propagation evolution situation in the social network is perceived, and the method can be widely applied to the relevant field of information propagation.

Method for detecting density of passengers in bus on basis of image analysis

The invention discloses a method for detecting density of passengers in a bus on the basis of image analysis. The method includes the steps that (1) a binocular camera is arranged at the front end of the inside of the bus, and video images are shoot; when no passengers are in the bus, the images of the binocular camera are processed, so that depth images of the background in the bus are obtained; (2) a foreground objective of the area where the passengers stand in the bus is obtained; (3) by means of the perspective effect of the binocular camera, perspective correction is carried out on the image of the foreground objective of the area, the density is primarily divided into a low level and a medium and high level according to the area of the foreground, and if the density is in the medium and high level, the fourth step is carried out; (4) the video image of one camera body of the binocular camera at the same moment is captured and grayed, and texture features of the image are extracted; (5) detected passenger density information and geographical position information are stored. The method effectively solves problems occurring in the prior art, and the density of the passengers in the bus is detected by analyzing the images shot by the binocular camera.

Road condition broadcasting method and system based on cloud short-term path prediction

The invention discloses a road condition broadcasting method and system based on cloud short-term path prediction. The method comprises the following steps: a vehicle-mounted terminal acquires vehicleposition coordinates, and the coordinates are sent to a cloud server through wireless communication; the vehicle-mounted terminal converts the vehicle position coordinates, the cloud server calculates the driving distance of the vehicle according to the position data received in real time, and the received vehicle position is saved to a database; based on an RNN trained by successive data of thedatabase and the current travel data, the cloud server predicts the driving path of the vehicle; the road condition information of road sections within a radius coverage area and the road intersectiongenerated by the predicted vehicle travel paths are taken, and the congestion road section information which needs to be broadcasted can be acquired; and through a TTS technology, the vehicle-mountedterminal converts formed text information to voice to be broadcasted. Delays caused by accidents or road congestion and the like can be reduced, a vehicle flow can be reasonably and effectively evacuated, the time on the road is saved, and safety hazards are reduced.
