Multi-view thermal imaging monitoring system

Abstract

The invention relates to a monitoring system, in particular to a multi-angle thermal image monitoring system, and belongs to the technical field of infrared imaging. According to the technical scheme, the multi-angle thermal image monitoring system comprises an infrared camera set used for collecting infrared images in a monitoring field of vision. The infrared camera set is connected with an image processing sub-system, and a calibration lookup table is preset in the image processing sub-system. The infrared images of an object in the monitoring field of vision are collected through the infrared camera set and transmitted to the image processing sub-system. The image processing sub-system determines the three-dimensional coordinates of the object according to the calibration lookup table and displays the depth of field of the object. According to the multi-angle thermal image monitoring system, real-time three-dimensional space positioning of a concerned scene and the object is achieved, more image information is collected, the monitoring effect of thermal images is improved, and the multi-angle thermal image monitoring system is wide in application range, safe and reliable.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a multi-view thermal image monitoring system, which belongs to the technical field of infrared imaging. Background technique [0002] Infrared thermal imaging technology was developed in the late 1920s. Whether it is in the military field or the civilian field, infrared thermal imaging technology plays an important role. Infrared thermal imaging technology overcomes the shortcomings of low-light imaging technology that relies entirely on natural light in the environment, can identify objects behind camouflage and obstacles, and provides better vision conditions for night video surveillance. [0003] The infrared thermal imager uses the infrared detector and the optical imaging objective lens to receive the infrared radiation energy distribution pattern of the measured target and reflect it on the photosensitive element of the infrared detector to obtain an infrared thermal image, which is c...

AI Technical Summary

Problems solved by technology

[0005] At present, the traditional infrared thermal imaging system is mainly used in the civilian field for fire detection of electrical equipment, target monitoring at night and in harsh weather conditions, fire monitoring, camouflage and hidden targets in the fields of electric power, metallurgy, transportation, public security, fire protection, and customs. It can only realize a single detection or video surveillance function for the target, and cannot provide the spatial positioning information of the target object in the concerned scene.
