Embodiment Construction

[0059] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0060] At present, electronic devices usually use sensors with Red, Green and Blue filters to receive reflected light from objects and generate color images (RGB). The color images obtained are in line with human visual perception, but are vulnerable to insufficient ambient light, fog days and other adverse weather effects. However, infrared images (NIR, Near Infra-redSpectrum, near-infrared light), which describe the thermal radiation of objects, have stronger penetrability than RGB images under insufficient illumination, fog and other severe weather, and the details are ...

Abstract

The invention relates to an image processing method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring a first image and a second image to be processed, wherein the first image is shot by a first camera, and the second image is shot by a second camera; performing pixel mapping on the second image based on a pixel mapping relationship betweenthe first camera and the second camera to obtain a mapping image corresponding to the second image, wherein the pixel mapping relationship is determined based on a first camera response function of the first camera and a second camera response function of the second camera; and aligning the mapping image corresponding to the second image with the first image. By adopting the method, the image alignment effect can be improved.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to an image processing method, device, electronic device and computer-readable storage medium, and a pixel mapping method, device, electronic device and computer-readable storage medium of a binocular camera . Background technique [0002] Various electronic devices such as mobile phones and tablet computers have become indispensable tools in today's life. In order to meet people's needs for recording beautiful moments, electronic device photography has become an important function. With the upgrading of electronic devices, more and more electronic devices are equipped with multiple cameras to meet people's increasing shooting needs. [0003] At present, in order to enhance the quality of images captured by electronic devices, images captured by multiple cameras are often aligned and fused, so that the information collected by multiple cameras can be fused, which...
