  • Patent number: 11361495
    Abstract: A system for three dimensional (3D) model texturing. The system includes a computing device configured to: instruct a camera to capture images of an object; construct a 3D model of the object based on the images; texture the 3D model using keyframes of the images to obtain a textured 3D model; generate guidance images by projecting the textured 3D model to camera poses of the keyframes; for each guidance image and keyframe pair: modify the guidance image and the keyframe based on their correspondence to obtain enhanced guidance image and warped image, combine the enhanced guidance image and the warped image to obtain harmonized image, and project color from the harmonized images to the 3D model to obtain textured 3D model.

  • Patent number: 11321916
    Abstract: A method for virtual fitting, includes providing a customer avatar and a garment model of a selected garment; registering the garment model to the customer avatar to obtain a dressed garment; capturing a motion image of the customer; performing simulation to the customer avatar and the dressed garment based on the motion image; rendering the simulated customer avatar-garment; and displaying the rendered avatar-garment on a displaying device. Rigging is performed to the dressed garment to obtain rigged garment, and cloth simulation is performed to the dressed garment model to obtain simulated cloth. Each vertex of the simulated cloth has a distance to nearest body mesh vertices on the simulated customer avatar, and the simulated garment is the rigged garment when the distance is less than 0 or the distance is greater than a threshold distance. Air mesh between the avatar and the garment is used for collision detection.
