Abstract

The invention provides an intelligent video acquisition system and method, and the system comprises a video acquisition terminal, a LoRa gateway, and a server, and the adaptive communication connection between the video acquisition terminal and the server is established; the video acquisition terminal and the server carry out self-adaptive communication interaction; the server sends an instructionto the video acquisition terminal, specifies the type of an object needing to be identified by the video acquisition terminal, specifies the mode of sending acquisition information to the server by the video acquisition terminal to be an adaptive mode or a small data mode, and specifies the video acquisition mode of the video acquisition terminal to be a continuous video acquisition mode or a discontinuous video acquisition mode. According to the video acquisition system and method disclosed by the invention, videos can be acquired, the types of objects in the acquired videos can be identified, a proper video acquisition mode and a proper acquisition information sending mode can be adopted according to actual conditions, and the intelligent video acquisition system and method are suitablefor many application fields such as public safety monitoring and field scientific research.

Description

technical field [0001] The invention belongs to the field of the Internet of Things, relates to video acquisition, and in particular to an intelligent video acquisition system and method. Background technique [0002] With the rapid development of image processing, embedded and Internet of Things technologies, miniaturized, intelligent video capture systems that support wireless transmission are constantly being introduced, and are used in various fields such as public security monitoring and field scientific research. [0003] However, the existing video capture systems and methods are generally only for certain specific application scenarios, and it is difficult to use appropriate video capture systems based on actual conditions when encountering difficulties in mains power supply, insufficient wireless signal coverage, or unstable network services. The acquisition method and the appropriate acquisition information transmission method make it difficult to timely and effect...
