Abstract

The invention discloses a video monitoring and acquisition system with image enhancement functions. The video monitoring and acquisition system comprises an image obtaining apparatus for obtaining images, an analog-to-digital conversion apparatus AD, an image processing module which enhances the digital picture signals subjected to the analog-to-digital conversion, a digital-to-analog conversion apparatus DA, a video storage module, a monitor terminal, and a control center module for controlling the operation state of the whole system. The video monitoring and acquisition system employs an embedded hardware platform, and optimizes software algorithm. In this way, the size and power consumption of image processing hardware devices are substantially reduced, and real-time image enhancement can be realized. The video monitoring and acquisition system can be conveniently integrated with an image acquisition device, and modularized design facilitates free allocation of function modules. The video monitoring and acquisition system is more suitable for application situations, and the purchasing cost is lowered.

Description

technical field [0001] The invention relates to the technical field of video security monitoring, in particular to a video monitoring and acquisition system with image enhancement function based on embedded real-time image processing technology. Background technique [0002] With the development of social economy, the security surveillance market with video surveillance as the core has achieved considerable development. However, when the existing video monitoring system is designed, it does not take into account the adverse effects of severe weather conditions (such as fog, rain and snow) on the imaging equipment. Therefore, the use effect of this type of equipment in severe weather is not ideal. [0003] To solve this problem, image researchers have developed many image enhancement algorithms to process the degraded images acquired in bad weather to achieve better viewing effects. However, this type of image enhancement algorithm generally has a large amount of calculation...
