Title:
MODEL GENERATION METHOD AND APPARATUS, IMAGE PERSPECTIVE DETERMINING METHOD AND APPARATUS, DEVICE, AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/249401
Kind Code:
A1
Abstract:
A model generation method and apparatus, an image perspective determining method and apparatus, a device, and a medium. The model generation method comprises: according to a preset collection system, collecting point cloud data and a plurality of frames of image perspectives to obtain the coordinate data of the point cloud data and a plurality of image collection time points having one-to-one correspondence to the plurality of frames of image perspectives (S110); determining a pose matrix corresponding to each of the plurality of image collection time points, and according to the pose matrix corresponding to each image collection time point and the coordinate data, generating a point cloud perspective under each image collection time point (S120); and using the point cloud perspective under each image collection time point and the image perspective under each image collection time point as a set of training samples, and according to a plurality of sets of training samples, training an original neural network model so as to generate an image conversion model used for converting the point cloud perspective into the image perspective (S130).
