Embodiment 1

[0046] A method for automatically synchronizing locomotive video files and running record files of the present invention, first select a section of locomotive running record files, judge the running state of the locomotive and its duration by the speed of the locomotive in the running record files, and then select a section of locomotive video files (this section The selected time period of the locomotive video file includes the selected time period of the locomotive operation record file), by processing the image in the locomotive video file, obtain the running state of the locomotive and its duration, and finally compare the two files to determine the running state of the locomotive. The method of determining the corresponding running state of the locomotive in the two files, and synchronizing the two files according to the occurrence time of the determined running state. Specifically, the following steps are included:

[0047] Select a piece of locomotive running record fil...

Embodiment 2

[0063] The locomotive video file of the present embodiment and the automatic synchronization method of the running record file, such as figure 1 As shown, the specific process is as follows:

[0064] 1. Use the camera to collect video.

[0065] The camera is used to collect the running road conditions of the locomotive and the situation in the cab of the locomotive in real time. In order to improve the accuracy of the detection, a detection is performed every 11 frames of images are collected. In this embodiment, multiple detections are required to obtain the appearance time of the corresponding state information of the locomotive and duration.

[0066] 2. Preprocess the collected images.

[0067] Affected by the environment inside the locomotive and the environment outside the window, it is necessary to perform some preprocessing on each frame of the collected image, and reduce the amount of image data by using grayscale processing, so that it changes from a three-channel i...

Abstract

The invention relates to a method and device for automatically synchronizing locomotive video files and running record files. Firstly, a section of locomotive running record files is selected, and according to the locomotive speed information in the running record file, the occurrence time and duration of the running state of the locomotive are judged; and then by Collect the images in the locomotive video file, judge the running status and duration of the locomotive according to the pixel value of the difference image and the set threshold; then find out the locomotive video file that matches the running record file The running status and duration of the locomotive, so as to realize the synchronization of the locomotive video file and the running record file. The present invention does not require additional hardware equipment, and can realize the synchronization of locomotive video files and operation record files only through the existing equipment installed on the locomotive. On the basis of not increasing economic costs, the synchronization efficiency is high, and industrialization is facilitated.

Description

technical field [0001] The invention belongs to the technical field of image processing, in particular to a method and device for automatically synchronizing locomotive video files and running record files. Background technique [0002] The locomotive video file is a file formed by installing a video monitoring device on the locomotive, which records the running road conditions of the locomotive and other information throughout the process. The operation record file is a file formed by the train operation monitoring device, which can accurately record information such as the train operation status. However, in actual situations, there are always some deviations in time between the information recorded by the two. In order to quickly retrieve information such as the running status of the locomotive in the video and improve the efficiency of video analysis, we need to synchronize the locomotive video file with the running record file. . The traditional method is to manually ...
