Abstract

The invention relates to an image acquisition terminal for an embedded system web server and an image acquisition method. The terminal comprises a CPU, wherein the CPU is connected with a digital camera through a USB interface, is connected with a U disk through the USB interface, leads out an RS232 interface through a UART interface, and is connected with a flash storage, an SDRAM dynamic storage, a network controller and an RTC backup battery used for supplying power to an RTC circuit on the CPU. The image acquisition method comprises the following steps: recording the time for acquiring video data; acquiring image information shot by the camera; processing the acquired image information; saving the processed data in the U disk; and uploading the acquired image information by using the CPU. The image acquisition terminal has the advantages of small volume, light weight and easy quick installation; and the image acquisition method is easy to realize.

Description

technical field [0001] The invention relates to an image acquisition terminal and an image acquisition method, in particular to an image acquisition terminal and an image acquisition method of an embedded system Web server. Background technique [0002] The current information age is an era built on the basis of the network. The IP network based on the TCP / IP protocol, such as the Internet, Intranet and Extranet, is developing with an astonishing and irresistible trend. The network-based digital video surveillance system is the mainstream of video surveillance system development. The traditional video surveillance field is facing great changes, and the analog video system is gradually being replaced by the digital video system. [0003] Existing image acquisition terminals: [0004] 1. High-end processors with strong computing power and high-definition cameras are used, which makes them expensive and cannot be installed on a large scale. [0005] 2. Since the current vide...
