A USB camera monitoring system and method based on android platform

Abstract

The application provides a USB camera monitoring system based on the Android platform, including a video acquisition unit, a processing unit, a display screen and a storage unit, the video acquisition unit includes a microphone and multiple USB cameras, and the processing unit is used to control the The display screen previews in real time the multi-channel image data collected by multiple USB cameras, and is also used to simultaneously encode and synthesize the audio data collected by the microphone and the multiple image data collected by multiple USB cameras in a multi-threaded manner to obtain a multi-channel video, and store multiple videos in the storage unit. The present application also provides a monitoring method of a USB camera monitoring system based on an Android platform. This application can realize multiple USB cameras to simultaneously preview, take pictures and record videos on the Android platform without interfering with each other.

Description

technical field [0001] The present application relates to the technical field of monitoring, in particular to an Android platform-based USB camera monitoring system and a monitoring method thereof. Background technique [0002] In the context of the rapid development of the Internet of Things, the application of the Android platform occupies a large market in the entire Internet of Things industry. The application range and application field of the Android platform are still expanding, and the camera is an important part of the machine sense. It is ubiquitous in today's society, so combining the two is an inevitable choice of the times. [0003] At present, the demand for multi-channel video collaboration in the society is more and more extensive, and under the Android platform, real-time preview and recording of a single USB camera can be realized, and real-time preview and recording of multiple ordinary cameras can also be realized, but these two This combination is not i...

Problems solved by technology

[0003] At present, the demand for multi-channel video collaboration in the society is more and more extensive, and under the Android platform, real-time preview and recording of a single USB camera can be realized, and real-time preview and recording of multiple ordinary cameras can also be realized, but these two This combination is not ideal

The first solution is mainly aimed at unilateral monitoring equipment, such as recorders, etc. This solution is relatively mature, but each camera must correspond to a module or chip. When multiple USB cameras need to work at the same time, the cost is high; the second Although the two solutions can realize multiple ordinary cameras working at the same time, such as the dual-camera function of a mobile phone, one is the main camera and the other is an auxiliary camera. The auxiliary camera is mainly used to supplement some parameters of the main camera and the amount of light. A video, that is, although it can realize dual-channel preview, it is only a single-channel video, and the compatibility is poor
