Embodiment 1

[0046] Such as figure 1 As shown, a method of multi-channel audio, video, radar mixed synchronous playback, including the following steps:

[0047] S11, acquire data to be processed, and store according to the preform, obtain the first data, the to process data including audio data, video data, and radar data;

[0048] S12, according to the first data and the preset information data, the establishment of each data time array is obtained, and the first time axis is obtained, and the standard time array is established according to the time range of the predetermined information data. Get the second time axis;

[0049] S13, based on the second time axis, the first time axis is adjusted according to the comparison analysis method, so that the respective data is synchronized in accordance with the second time axis.

[0050] In the present embodiment, audio data and video data are first obtained according to different devices, where the camera video data is stored in a common video pack...

Embodiment 2

[0053] Such as figure 2 As shown, a method of differential adjustment of the first time axis, enabling it to synchronize playback, including:

[0054] S21, the judgment of whether or not the first time axis is matched according to the second time axis;

[0055] S22, if not, the first time axis is paused or a time acceleration operation until the time of the first time axis matches the time of the second time axis, so that the data is described as described. The second timeline is synchronized.

[0056] In the present embodiment, after the first time axis and the second time axis are constructed, in order to achieve multiple different types of data can be synchronously played back, first, according to the standard timeline, the second time axis is accurate, playback And judge whether or not the time at this time in the first time axis of each channel is matched, if you match, then you don't need to adjust, you can implement synchronous playback, if you don't match, then you need to...

Embodiment 3

[0059] Such as image 3 As shown, a multi-channel audio, video, radar mixed synchronous playback device, including:

[0060] Data storage module 10: Used to obtain data to be processed, and store according to the preform, obtain the first data, the to process data including audio data, video data, and radar data;

[0061] Timeline establishment module 20: Used to establish establishment according to the first data and the preset information data, obtain the first time axis, and perform according to the time range of the predetermined information data The establishment of the standard time array obtains the second time axis;

[0062] Synchronous playback module 30: For the second time axis, the second time axis is adjusted to the first time axis according to the comparative analysis method, so that the respective data is synchronously played back in accordance with the second timeline.

[0063] One embodiment of the above apparatus is, in the data storage module 10, the data to be p...

Abstract

The invention provides a multi-channel audio, video and radar mixed synchronous playback method and device, and relates to the field of scene monitoring, and the method comprises the steps: obtaining to-be-processed data, and storing the to-be-processed data according to a pre-format to obtain first data; establishing a time array of each path of data according to the first data and preset information data to obtain a first time axis, and establishing a standard time array according to a time range of the preset information data to obtain a second time axis; and by taking the second time axis as a reference, performing difference adjustment on the first time axis according to a comparative analysis method, so that each path of data is synchronously played back according to the second time axis. According to the method and the device, synchronous playback of multi-category data can be realized, the whole process is automatically carried out, the operation difficulty is reduced, the fluency of the system is improved, customized setting of the playback standard time is realized, setting can be carried out according to an actual scene, and the practicability is improved.

Description

Technical field [0001] The present application relates to the field of scene monitoring, and in particular, a method and apparatus for multi-channel audio, video, radar mixed synchronous playback. Background technique [0002] The operation scenario data of each seat personnel includes a plurality of different audio data sources and a plurality of different video data sources, including but not limited to work scenes (generally referring to the camera), one or more computer screen operations (General finger Screen recording), cable call, wireless call, and radar data, etc.; currently data playback or multiplexing playback in the general sense is playback or multiplexing playback of the same category data, including play, pause, shift, jump Waiting for operation. [0003] For some specific scenes, such as accident surveys, operational specification demonstrations, it is necessary to mix synchronous playback of different categories of multi-channel monitoring data at the time, and ...
