Object digitization method and device, facial scanning method and device, and handheld digitization device

Abstract

The present disclosure provides an object digitization method and device, a facial scanning method and device and a handheld digitization device, including: obtaining spectral images of a target object under multi-node illumination light sources; obtaining a response function of the spectral images; recovering reflection spectra of the target object based on the response function and a reflection database; obtaining a detailed point cloud of the target object and digitizing the target object based on the detailed point cloud and the recovered reflection spectra of the target object. The present disclosure can rapidly recover the true reflection spectra and high-resolution three-dimensional shape of the target object, thereby creating a realistic digital avatar, applicable to digital domains such as the metaverse. Based on this, the present disclosure can effectively acquire the reflection spectra and three-dimensional information of a face, enabling personal facial health monitoring and beauty applications.
