An embedded camera video acquisition and network transmission module and a working method thereof belong to the technical field of video network transmission. The module comprises hardware and software, wherein the hardware comprises a USB camera and an embedded development platform, and the software are written into the embedded development platform. The embedded development platform is a development board provided with an S3C2410 chip and an LINUX operating system. The working method comprises video data acquisition by the camera, network transmission and adjustment of image brightness and contrast. The method can control the USB camera to acquire video images on the S3C2410 embedded development platform, play the acquired video images in a local QT-compiled visualized window by adopting QT video display technology, and adjust the formats of the acquired images so that the data amount of the images is furthest compressed on the premise of ensuring the quality of the images and the compressed video data are transmitted by the network through the network programming technology under linux; and the method can adjust the brightness and the contrast of the acquired images.
Description
technical field [0001] The invention relates to an embedded camera video acquisition and network transmission module and a working method thereof, belonging to the technical field of video network transmission. Background technique [0002] With the vigorous development of the network, camera video display and network transmission technology have been more and more widely used in daily life and production. Camera video display and network transmission technology generally includes the process of camera video collection, video display and video network transmission. This technology can display the video data collected by the camera in real time, or compress it according to a specific compression standard to form a sequence of video frames. In order to adapt to different transmission networks, a large video frame will be split into several data packets, and the corresponding control information will be added to each, and sent to the client through the network. [0003] In ad...
