Embodiment Construction

[0018] The inventive method is made up of three parts of image acquisition module, image processing module and intelligent alarm module, and the hardware equipment involved in three parts is as follows: figure 1 As shown, a large-field-of-view wide-angle lens imaging system 1, an ordinary PC 2, and an alarm device 3; wherein, the ordinary PC 2 is connected to the large-field-of-view wide-angle lens imaging system 1 and the alarm device 3 through transmission cables.

[0019] The concrete workflow of the inventive method is as figure 2 Shown:

[0020] Step (011): start, large field of view wide-angle lens imaging system 1 collects images to obtain the global image 4 of the current frame; large field of view wide-angle lens imaging system 1 inputs the global image 4 to a common PC 2 through a transmission cable;

[0021] Step (012): common PC 2 carries out moving object detection to global image 4, judges whether there is moving object 5, if yes, then carries out step (013) to...

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...
