Embodiment Construction

[0018] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings: the application of a video surveillance image processing device in a video system is as follows: figure 1 As shown, its front end is connected with image sensors such as CMOS or CCD, and its back end is connected with digital signal processor (DSP) so as to form a video processing system. In the present embodiment, FPGA has adopted the CyclonelI series FPGA chip of Altera Company, The digital signal processor (DSP) adopts TTI's C64x series DSP processor. A video monitoring image processing device can preprocess the video image data of the front-end image sensor, and transmit the preprocessed video image data to the DSPe

[0019] Such as figure 2 As shown, the FPGA-based preprocessor is composed of an image preprocessing module and a FIFO buffer module. The input end of the image preprocessing module is connected to the video image data and sync...

Abstract

The invention relates to a video monitoring image processing unit in the field of security monitoring. The video monitoring image processing unit is characterized by being formed through connection of an image preprocessing module and an FIFO buffer module; the input end of the image preprocessing module is communicated with video image data and synchronizing signals; and the output end of the FIFO buffer module outputs the processed video image data and DSP data reading request signals. The video monitoring image processing unit provided by the invention achieves a function of real-time preprocessing of video image data from a high-resolution image sensor, solves the video acquisition port transmission bottleneck problem existing in video image data processing by a DSP, has the characteristics of being simple and convenient to achieve, strong in compatibility, high in stability, and convenient to modify and upgrade, and can be widely applied to video monitoring systems adopting large-pixel image sensors.

Description

technical field [0001] The invention belongs to the technical field of video monitoring, in particular to a video monitoring image processing device. Background technique [0002] In the field of security monitoring, a large number of video surveillance systems are required. The cameras in the video surveillance system record the monitoring site, and the monitoring personnel can see the actual situation of the monitoring site from the display device without going to the site to patrol. Although ordinary surveillance cameras can record every position of a panoramic 360-degree viewing angle, they cannot monitor the situation of the entire panoramic field of view at the same time. In order to solve this problem, more and more video recording devices that can collect panoramic mirror, fisheye lens, etc.) are applied in the video surveillance system, the principle of this video surveillance system is: through the characteristics of the panoramic camera equipment, the entire panor...
