Method and system for tracking moving target based on optical flow method
2015
Provided in the present invention are a method and system for tracking a moving target based on an optical flow method, the method comprising: providing video images, and implementing pre-processing of the images to generate pre-processed images; implementing edge detection of the pre-processed images and using an optical flow method to extract target information from the pre-processed images, and on the basis of a combination of the edge detection information and the extracted target information, generating a complete moving target; using an optical flow method to perform estimation analysis of the moving target and using a forward and backward error algorithm pair based on feature point trajectory to eliminate light-generated false matching points; and constructing a template image and implementing template image matching to track the moving target. The method and system for tracking a moving target based on an optical flow method set forth in the embodiments of the present invention have the advantages of accurate and complete extraction and the ability to implement stable tracking over a long period of time.
