Embodiment Construction
[0029] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, the same numerals in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with this application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as recited in the appended claims.
[0030] Thermal imaging technology refers to the use of infrared detectors and optical imaging objective lenses 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. corresponding to the distribution field. In layman's terms, an infrared thermal imager converts...

The invention provides an image fusion processing method and device, equipment and a storage medium. The method comprises the following steps: acquiring a thermal imaging image, a visible light image and a near-infrared image for performing image acquisition on the same target object; the resolution of the visible light image is the same as that of the near-infrared image, and the resolution of the near-infrared image is greater than that of the thermal imaging image; each near-infrared pixel in the near-infrared image corresponds to a brightness value; each thermal imaging pixel in the thermal imaging image corresponds to a first heat value; determining M * N near-infrared pixels corresponding to each thermal imaging pixel according to the resolution of the near-infrared image and the resolution of the thermal imaging image; m and N are integers greater than 1; for each near-infrared pixel in the M * N near-infrared pixels, determining a target heat value of the near-infrared pixel according to the brightness value of the near-infrared pixel and the first heat value corresponding to the near-infrared pixel; and interpolating the visible light image according to the target heat value of the near-infrared pixel to obtain a fused target image.
Description
technical field [0001] The present application relates to image processing technologies, and in particular, to an image fusion processing method, apparatus, device, and storage medium. Background technique [0002] Thermal imaging is the technique of receiving infrared radiation emitted by a scene and converting the infrared radiation into a thermal image that indicates thermal patterns. Because it is not affected by light, it is widely used in the field of monitoring. [0003] At present, the resolution of mainstream thermal imaging cameras can only reach 20,000 to 80,000 pixels, which makes thermal imaging images unable to display some image details. Although there are high-resolution thermal imaging cameras on the market, the cost is higher. Therefore, some people propose to fuse the thermal value pixels provided by the thermal imaging image into the visible light image with a certain regularity to enhance the thermal imaging image, but the fusion effect is poor, so tha...
