Embodiment Construction

[0022] The present invention will be further described below.

[0023] A method for editing objects in an interactive real-scene video of a railway line, comprising the following steps:

[0024] (1) Decode and play the video to be edited: decode the video to be edited, and display the decoded frame image at the frame rate of the video to be edited, so as to achieve the effect of playing the video, and start playing from time 0 by default. The user can select any moment as the moment when the current playback starts, and after the setting is completed, the frame corresponding to the moment will be decoded directly;

[0025] (2) Determine the time when the target appears: watch the video to be edited and identify the target to be edited, and these targets will continue to exist in the video for a period of time; figure 1 A frame of image within range for a signal target to appear. Next, take this goal as an example to illustrate;

[0026] (3) Frame the target: within the time...

Abstract

The invention discloses an interactive editing method for targets in reality videos of railway lines and belongs to an image and video processing method. According to the method, on the basis of a visual interface, after a certain target is artificially selected in a few frame images, the position of the target in the other frames is tracked by utilizing a method of maximizing the local feature similarity; high-precision target tracking results can be obtained through adjusting the position and the number of the artificial selection; and a template image selected for the target is inserted atthe tracked target position to complete the editing of the target.

Description

technical field [0001] The invention belongs to an image and video processing method, in particular to an object editing method in an interactive real-scene video of a railway line. Background technique [0002] The driving training of train drivers is a key part of the training of railway staff, and it is also the core of ensuring the safety of trains. Driving training should enable the driver to be familiar with various railway signs and handle various situations proficiently and flexibly. In order to achieve this goal, it is necessary to provide a real driving environment during the training process, and the current mature video shooting technology can obtain smooth and real train driving scenes, which can effectively enrich the training content and simulate the real driving experience. [0003] The railway incidents contained in the real-scene video of the railway line captured in reality are very limited, which cannot meet the needs of flexible and diverse examination ...
