Pedestrian event detection method based on the shape feature and the trajectory analysis

The present invention provides a pedestrian detecting method based on the event and the trajectory shape feature analysis, background subtraction method by using a target obtained by the division of the foreground object, the same object on the communication domain using a block based method of marking, while recording the external communication domain and extract a rectangular geometry wherein object recognition is completed, when the pedestrian class identified object extraction target corner points, the corner points using the position tracking information matching corner, repeating the above process, the target trajectory can be obtained, the track seek segment inflection point, the inflection point is formed in each segment are made of linear analysis to achieve the target speed is obtained, the event analysis of the pedestrian on the basis of the state information, completion of road safety warning. The detection method is applicable to complex traffic scenarios can accurately identify pedestrian present within the range of video surveillance, tracking and alert, practical and high-value, has broad application prospects.
