Problems solved by technology

The front-end-based embedded traffic video acquisition system is a combination of software and hardware, usually composed of four parts: operating system, application program, peripheral hardware device and embedded microprocessor board, although the peripheral hardware device can rely on The existing front-end traffic monitoring equipment is upgraded and transformed. However, due to the high integration and complexity of embedded technology, which also involves the real-time transmission of traffic video big data, it still needs to be developed in depth with the help of auxiliary tools. The system has corresponding functions

Abstract

The invention discloses an embedded video collection system based on an ARM9 and a V4L2 interface. The system comprises a browser client, a special traffic video collection card integrated into an ARM microprocessor and camera elements. The camera elements collect field traffic video image data. The special traffic video collection card integrated into the ARM microprocessor reads images and carries out real-time data processing, transmits processed traffic video image data to the browser client through a network based on a transmission control protocol and displays collected traffic video images in real time by accessing the browser client. The scheme of the invention is wide in controllable range, high in expansibility, and high in system timeliness and stability.

Description

technical field [0001] The invention belongs to the field of traffic video collection and processing, and specifically relates to an embedded video collection system based on an ARM9 single-chip microcomputer and a V4L2 interface. Background technique [0002] With the development of social civilization and the advancement of science and technology, information has increasingly become a more important resource than traditional energy, and information will promote the further development of human society. In daily life, about 78% of the various information that people perceive from the outside world through the senses comes from vision. Visible images play an important role in our daily life. The sense of vision is the most direct and three-dimensional, and the traffic video surveillance system, as a tool for obtaining image information, can meet the needs of the traffic management department for obtaining image information. However, the current problems in the application ...
