Problems solved by technology

[0004] However, there are usually partial overexposures in the acquired non-visible light images, resulting in poor imaging quality of the non-visible light images, and thus the poor imaging quality of the final fusion image

Embodiment Construction

[0068] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0069] The following briefly introduces the technical terms involved in this application document.

[0070] Visible light is an electromagnetic wave that can be perceived by the human eye. The visible spectrum does not have a precise range. The wavelength of electromagnetic waves that can be perceived by ordinary human eyes is between 400 and 760 nm (nanometers). Non-visible light, in this application document, can be infrared light or near infrared light. Am...

Abstract

The embodiments of the invention provide an image acquisition method and device, electronic equipment and a computer readable storage medium. The image acquisition method comprises the following steps: firstly, acquiring a visible light signal in an incident light to acquire a target visible light image; acquiring a non-visible light signal in the incident light to acquire a non-visible light widedynamic range image; then registering the acquired target visible light image and non-visible light wide dynamic range image to acquire a registered image of the target visible light image and a registered image of the non-visible wide dynamic range image; and finally, fusing the two acquired registered images to acquire a target image, thereby completing image acquisition. The over-exposure phenomenon of the non-visible wide dynamic range image is significantly smaller than that of a non-visible low dynamic range image. Therefore, compared with the prior art, the image acquisition method hasthe advantages that the non-visible wide dynamic range image has richer image details, and the image fusion effect is good, thus guaranteeing the imaging quality of the finally fused image.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image acquisition method, device, electronic equipment and computer-readable storage medium. Background technique [0002] In order to ensure that the collected images cover more image information, the image acquisition equipment can use spectroscopic fusion technology to collect images. Fusion in spectroscopic fusion technology can be understood as: fusing visible light images and non-visible light images to obtain a fused image; where the fused image is a dual-band image, compared to the single-band visible light image and non-visible light image For any kind of image, it reflects more image information. The above-mentioned non-visible light signal may be: a near-infrared signal or an infrared signal. [0003] In the prior art, the basic process of image acquisition by an image acquisition device using spectroscopic fusion technology is: acquire a visible ...
