Problems solved by technology

[0003] But when there are multiple targets, it is very troublesome to find. We need to filter and filter out the target tracks that need to be found from the historical tracks of multiple targets; historical video recording requires us to watch all the videos in the time period we are looking for patiently. It takes a lot of time and energy to filter the historical videos of the channel and filter out the videos that need to be searched for, and the results obtained are not continuous, and the last search process needs to be repeated until the next viewing

Embodiment Construction

[0012] The present invention will be further described below in conjunction with specific embodiments.

[0013] combine figure 1 , a control method for synchronous playback of target map tracks and historical videos, comprising the following steps:

[0014] Step 1. Collect data, that is, collect all map track points of the target from the set moment;

[0015] Step 2. Divide the map track points according to the camera number and the storage time of the map track points, and start the timer;

[0016] Step 3. Use the collected data of the target map track point to control the playback of the historical video, so that the map track is synchronized with the playback of the historical video. The specific process is:

[0017] Step 3-1. Determine whether the map track and historical video playback is stopped: if yes, stop the timer message, send a message to Video to stop playing, and this timer ends; if not, perform step 3-2;

[0018] Step 3-2. Determine whether to play the map t...

Abstract

The invention discloses a target map track and history video synchronous playback control method. The target map track and history video synchronous playback control method comprises the following steps of collecting map track points of a target from a set moment, dividing a map track according to a camera serial number and the map track point storage time, starting a timer; controlling playback of a history video through collected data of the target map track points to enable the map track and playback of the history video to be synchronous. The target map track and history video synchronous playback control method achieves synchronous playback of the target map track and the history video and can conveniently, simply and rapidly know behaviors and dynamic states of some target in a certain time period.

Description

technical field [0001] The invention belongs to the field of computer monitoring and management, and in particular relates to a control method for synchronous playback of target map tracks and historical videos. Background technique [0002] Historical map tracks and historical video recordings are very important historical records. By looking up historical map tracks, we can know where a certain target has gone during a certain period of time, and then by looking up historical videos, we can know the behavior of a certain target during a certain period of time. . [0003] But when there are multiple targets, it is very troublesome to find. We need to filter and filter out the target tracks that need to be found from the historical tracks of multiple targets; historical video recording requires us to watch all the videos in the time period we are looking for patiently. It takes a lot of time and effort to filter the historical videos of the channel and filter out the videos...
