Abstract

The invention provides a method and device for demosaicing an image, electronic equipment and a storage medium, and relates to the technical field of image processing, and the method comprises the steps: determining an image participation coefficient based on the exposure duration information of a plurality of single-channel images, determining the weight information of a first matrix based on the image participation coefficient, and combining the first matrix based on the weight information to generate a single-channel to-be-processed matrix; performing interpolation processing at each channel position in a second matrix in the single-channel to-be-processed matrix, acquiring multi-channel pixel information at each channel position in an interpolation matrix, and generating a multi-channel image. According to the method, the device, the electronic equipment and the storage medium disclosed by the invention, the definition and the trueness of the demosaiced image are improved, the parallelization processing suitable for a GPU hardware architecture is realized, and the customer experience is effectively improved.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to a method and device for demosaicing an image, electronic equipment, and a storage medium. Background technique [0002] At present, in order to enable customers to obtain a real perceptual experience of the house, a "VR viewing" has been launched, which uses VR technology to truly restore the three-dimensional scene of the house. Users can roam and visit from multiple angles through keyboard and mouse control. Indoor and other scene data can be obtained through panoramic cameras, depth cameras, lidar and other equipment to construct a 3D scene of the listing. "VR viewing" needs to integrate and apply multiple technologies. The house photos presented to customers need to be processed by ISP (Image Signal Process, Image Signal Processing). During the ISP processing, the images need to be demosaicked. Since the final photos presented to customers during the VR...
