Video scene different place reconstruction method

Abstract

The invention discloses a video scene different place reconstruction method. The method is characterized by placing two field angle calibration rulers in an original video scene and making vertical marker lines of the two field angle calibration rulers in a monitoring frame be located at left and right boundaries of the monitoring frame, and measuring a spatial position relationship parameter of the two field angle calibration rulers and a monitoring camera in the original video scene; and placing the field angle calibration rulers and a reconstruction camera based on the parameter obtained from the original scene in a different place, comparing static images saved in the original video scene with videos captured by the reconstructed camera, adjusting a reconstruction camera parameter andacquiring a reconstructed video scene that is exactly the same as a field angle of the original video scene. By using the method, the video scene that is exactly the same as the field angle of the original video scene can be constructed in the different place, a simulation video can be recorded in the different place which is far away from the original video scene, a three-dimensional dynamic characteristic curve of a criminal suspect is made and a personal identification method requirement based on a dynamic characteristic is satisfied.

Description

technical field [0001] The invention relates to a dynamic feature-based personal identification technology, in particular to a method for constructing a video scene at a different place with the same viewing angle as the original video scene, which is adopted for implementing the dynamic feature-based personal identification method. Background technique [0002] CN 101901337 A discloses a personal identification method based on dynamic features. The method decomposes the video recording of a dynamic target person into a series of photos in chronological order; makes marker points on the target person; measures the horizontal coordinates and vertical coordinates of the marker points Coordinates; make the XY curve of the coordinates, the XT curve of the horizontal coordinates and time, and the YT curve of the vertical coordinates and time; make the dynamic video recording of the suspect under the same conditions as the above-mentioned target person’s state factors, and decompos...

AI Technical Summary

Problems solved by technology

In some cases, the suspect is far away from the original video scene or there are special difficulties in bringing the suspect to the original video scene, which restricts the implementation of the dynamic feature-based personal identification method disclosed in CN 101901337 A
