Problems solved by technology

With the expansion of the monitoring area in the industrial site and the increase of monitoring equipment, the management of the remote monitoring management terminal on the on-site monitoring equipment is cumbersome. On the one hand, different data use different transmission channels, and the corresponding receiving thread needs to be designated for the terminal to receive and process. , the increase of receiving channels increases performance requirements; on the other hand, the wired connection mode of monitoring equipment has many physical restrictions on equipment deployment and movement, which is not conducive to large-scale use

Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] Overall hardware design framework of the present invention figure 1 As shown, the system can be divided into embedded processing terminals and PC clients according to different deployment locations. The high-definition image acquisition device of the embedded processing terminal is composed of an OV5640 camera integrated board. The embedded processing terminal is based on the Samsung S5P6818 multi-core processor to expand the peripheral circuit. According to the different functions of each part, the hardware is divided into high-definition image acquisition module, memory module and peripheral interface module. Among them, the peripheral interface module is mainly composed of a power supply module, a debugging interface module, an HDMI display module and a network transmission module. The PC client is an additional module of ...

Abstract

The invention discloses an embedded high-definition video acquisition and data stream transmission system. Based on a Samsung S5P6818 core board, an OV5640 camera integrated board card is adopted to acquire high-definition image data, a multimedia hardware codec integrated in the core board is adopted to carry out compressed encoding on the image, an algorithm processing algorithm is used to extract image features, and a real-time video and a feature parameter data stream are published in a local area network through a streaming media server built on the board. Thus, a remote PC client can receive the video streaming data and the image feature parameter data, and through decoding, display and local storage, functions such as historical query are supported.

Description

technical field [0001] The invention relates to the field of real-time video monitoring and analysis, in particular to an embedded high-definition video collection and data stream transmission system. Background technique [0002] With the wide application of machine vision in the industrial field, it becomes possible to develop and use monitoring systems to replace the existing manual observation methods at industrial sites, and to conduct 24 / 7 online monitoring. On the one hand, the monitoring system obtains real-time images of the area through the image acquisition device, and sends them to the remote terminal for storage and viewing after certain processing, replacing the monitoring method of manual on-duty; on the other hand, using image processing algorithms and working condition recognition algorithms The specified object is extracted and separated from the image features, and the actual state of the industrial site is judged according to the extraction results.
