Thermal imaging fusion visible light image processing method, system and storage medium

Abstract

The invention relates to a thermal imaging fusion visible light image processing method, system and storage medium, comprising the following steps: 1, a camera collects visible light data and outputsan RGB image; 2, an infrared detector collects infrared radiation data and outputs that data; 3, RGB image backup; 4, convert that RGB image into a grayscale image; 5, Gaussian filtering of grayscaleimage; 6, calculate that gradient and the direction; 7, non-maximum suppression; 8, adaptive double threshold calculation; 9, image edge detection; 10, connecting edge points to output edge image; 11,synthesize an RGB image with edge lines; 12, bad point treatment; 13, first-order hysteresis filter; 14, non-uniformity correction; 15, adde a color palette to convert that color palette into an infrared thermal image; 16, infrared thermal image enhancement. 17, an image enlarge adaptive screen; 18, image display. The invention fuses visible light images by infrared thermal imaging, so that humaneyes can better observe the temperature distribution of the measured scene from the thermal imager.

Description

technical field [0001] The invention discloses a thermal imaging fusion visible light image processing technology, in particular a thermal imaging fusion visible light image processing method, system and storage medium, belonging to the technical field of thermal imaging processing. Background technique [0002] Any natural object will radiate infrared rays to the surroundings. Thermal imaging processing technology refers to the use of optical imaging objective lens and infrared detector to receive the infrared radiation energy of the measured target and reflect it on the photosensitive element of the infrared detector, so as to obtain the graph of the heat distribution on the surface of the object. This thermal image corresponds to the heat distribution field on the surface of the object. Generally speaking, infrared thermal imaging is to convert the invisible infrared energy emitted by an object into a visible thermal image, that is, an image of the temperature distributio...
