An accelerated processing method for a large field of view intelligent video surveillance system

Abstract

The invention relates to an accelerated processing method of a large field of view intelligent video monitoring system, and belongs to the fields of computer image processing technology and photoelectric detection technology. This method uses a large field of view imaging device to collect images; uses a transmission cable to input the images into a computer in real time; performs image processing in the computer, and sends an alarm if it meets the detection requirements of the monitoring system. This method is the first to propose a distortion-free fast projection method for local viewing angles in a large field of view. Break the conventional practice of the existing intelligent video surveillance system to complete the distortion correction of the global image first, and then perform operations such as moving target detection and recognition; first complete the detection of moving targets in the global large field of view, and then only perform local Distortion correction and recognition are performed on the small viewing angle image, which reduces the amount of calculation data and reduces the time cost of image processing. On the premise of ensuring accurate recognition, it meets the requirements of real-time online processing of the monitoring system.

Description

technical field [0001] The method of the invention relates to an accelerated processing method of a large field of view intelligent video monitoring system, and belongs to the fields of computer image processing technology and photoelectric detection technology. Background technique [0002] With the development and popularization of computer science, image engineering, pattern recognition, artificial intelligence and other disciplines, intelligent video surveillance systems with functions such as moving target detection and recognition have been widely used in various fields of national economy and national defense construction. It plays a huge role in the safety of life and property of the country and the people, and in ensuring the normal operation of all walks of life and various sectors of society, and has broad application prospects. However, due to the limitation of the field of view angle of the camera device, the traditional monitoring system can only monitor the sc...

Problems solved by technology

However, this kind of camera usually has a higher resolution and a larger amount of data than ordinary cameras; at the same time, due to the large field of view, the image has serious optical distortion. In order to avoid its interference to the later target recognition and other operations, it is necessary to distort the image with high precision Correction; these have greatly increased the amount of calculation for video image processing, and become a difficult problem to be solved for the real-time performance of the monitoring system
