Embodiment approach

[0029] by attaching image 3 The schematic diagram of the parallel processing of the dual-processor of the camera, you can understand the parallel implementation of the ARM chip processor and the DSP chip processor, as follows:

[0030] The original image data of a dual-stream high-definition camera is on the order of millions. The camera needs to perform complex JPEG algorithm encoding and H.264 algorithm encoding on the original data, and then pass the encoded JPEG image data and H.264 video data through The local area network is transmitted to the client monitoring software. These huge calculations are a heavy burden on the single-core processor, and will cause the high-definition camera to have a very low capture frame when capturing JPEG images or H.264 videos. Rate. Therefore, this program adopts the method of dual-core division of labor and parallel processing, and uses two processors, namely the ARM chip processor and the DSP chip processor, to perform parallel operat...

Abstract

The invention discloses a dual-code stream high-definition camera applied to intelligent transportation, and the camera provided by the invention adopts a high-definition dual code stream technology, wherein one path of code stream is used for transmitting the high-definition video streams which can be used for carrying out video monitoring on a traffic field, and the other path of code stream is used for transmitting high-definition image streams which can provide image analysis for the traffic field. The dual-code stream high-definition camera combines the video stream with the image stream. During real-time traffic monitoring, the high-definition video stream and the high-definition image stream can be simultaneously displayed, thereby effectively utilizing the existing resource, lowering the cost for purchasing the camera, and greatly satisfying various application requirements of the machine vision field. The dual-code stream high-definition camera has the advantages of professional and delicate appearance, outstanding performance and integrally integrated functions, is simple to install and use, and can be widely applied to fields, such as intelligent transportation, electronic polices, safety protection monitoring, industrial production and detection, medical microscopic fields and the like.

Description

technical field [0001] The invention relates to the realization of a dual-stream high-definition camera, which belongs to the technical field of machine vision image measurement and pattern recognition, and can be applied to intelligent transportation, machine vision, semiconductors, security monitoring, industrial production and detection, medical microscopy, and the like. Background technique [0002] With the development of image processing and pattern recognition technology, machine vision systems have been widely used in the field of intelligent transportation. [0003] HD camera is a highly integrated miniature machine vision system. Traditional solutions for traffic monitoring using high-definition cameras use only one stream of image data or video data for monitoring. For the monitoring scheme using image data, although it can save each frame of image collected by the camera in the computer and perform image analysis operations, it cannot meet the needs of real-time...
