Embodiment Construction

[0010] Such as figure 1 As shown, an image mosaic reconstruction and global monitoring method that improves visibility and viewing distance includes the following steps: 1. Install cameras at a given interval of visibility, and each camera captures images of the surveillance area in a given direction and distance range ; 2. The images captured by each camera are transmitted to the computer station; 3. The image processing system performs pre-processing such as noise removal, distortion removal, and feature extraction on the regional images captured by each camera. If the weather is foggy or rainy, the computer The image processing system performs defogging or rain removal processing on the acquired images; 4. The computer image processing system performs a series of moving object detection, target recognition, line or runway integrity detection, and foreign object detection on the acquired images of each camera area Abnormal event detection, alarm and image enhancement process...

Abstract

The invention discloses an image splicing reconstruction and overall monitoring method for improving visibility and visual distance, which comprises the following steps of: (1) arranging cameras according to given visibility spacing distance; (2) enabling each camera to respectively capture images in monitoring areas in given directions and ranges, and respectively transmitting the captured images to a computer for removing noise, rain, fog and distortion, enhancing the images, detecting abnormal events and carrying out other preliminary treatment processes; and (3) enabling an image processing system of the computer to carry out splicing reconstruction on the images in the section range between two adjacent cameras to form overall monitoring images, and modifying the spliced images by utilizing the augmented-reality technology according to the known information so as to acquire overall monitoring images and detect abnormal events. The method disclosed by the invention can be used for acquiring wide-range and long-path scene reconstruction images with sufficient visibility and visual distance, can be used for important video monitoring places, is especially suitable for solving the problem of insufficient visibility when a train runs or an airplane in an airport takes off or lands, and provides comprehensive observation information for the safe operation of the train or the airplane.

Description

technical field [0001] The invention relates to an image mosaic reconstruction and global monitoring method for improving visibility and visual distance, which belongs to the technical fields of image processing, pattern recognition, computer vision and computer graphics, and specifically relates to a series of image mosaic, scene reconstruction, and intelligent monitoring methods Apply algorithms. Background technique [0002] Video surveillance systems have been widely used in real life, such as urban traffic video surveillance systems, building video surveillance systems, railway video surveillance systems, etc. From a technical point of view, video surveillance technology can be divided into two types: manual monitoring and computer intelligent monitoring, and intelligent monitoring mainly uses various technologies of computer vision to automatically monitor abnormal events and behaviors in a specific environment. The advantages of manpower and automatic alarm, the appl...
