Embodiment l

[0031] This embodiment provides an embedded video enhancement system of open source server software, including a default parameter setting module, an initialization module, a video image input module, a video image cache module, a video image enhancement module and a video image output module, as shown in FIG. 1 The specific workflow of each module of the system is as follows:

[0032] The default parameter setting module receives the defined default parameters, analyzes these parameters at the same time, and passes the obtained results to the relevant components; the initialization module performs system initialization according to the default parameters, and sets the system exit signal. If the open source server software is multi-threaded synchronous work way, when the initialization module initializes, set the mutex and condition variables at the same time: the video image input module obtains the image data captured by the camera and performs compression encoding; the video...

Embodiment 2

[0060] In this embodiment, the image format collected by the camera type is JPEG format, and the video image enhancement module can directly use the histogram equalization processing method to enhance the image data in the video image buffer module. All the other are with embodiment 1.

Abstract

The invention relates to an embedded video enhancement system for open source server software. The embedded video enhancement system comprises a default parameter setting module, an initialization module, a video image input module, a video image cache module, a video image enhancement module and a video image output module, wherein the default parameter setting module is used for receiving defined default parameters; the initialization module is used for conducting system initialization according to the default parameters and setting a system exit signal; the video image input module is used for obtaining image data shot by a camera and conducting compressed encoding; the video image cache module is used for storing the image data processed by the video image input module; the video image enhancement module is used for enhancing the image data in the video image cache module by the adoption of a histogram equalization processing method and storing the enhanced image data to the video image cache module; the video image output module is used for outputting the enhanced image data. Compared with the prior art, the embedded video enhancement system can well achieve real-time monitoring of a monitored object under a weak-illumination situation.

Description

technical field [0001] The invention relates to the field of image processing, detection and embedded combination, in particular to an embedded video enhancement system of open source server software. Background technique [0002] With the development of science and technology, the intelligent management and monitoring of power systems has become the main development trend and direction of the power industry in the future, especially in recent years, the wide application of machine vision in power systems. Since the construction of the power grid in the power system involves multiple disciplines such as project management, civil engineering, and electrical engineering, as well as the cumbersome maintenance of daily facilities, the power industry is still an industry with high requirements for the field environment, with obvious cross-industry operations and harsh construction environments. The complexity of the actual terrain, coupled with various potential construction safe...
