POINT CLOUD ENCODING DEVICE, POINT CLOUD DECODING DEVICE, POINT CLOUD ENCODING METHOD, POINT CLOUD DECODING METHOD, AND PROGRAM
Document Type and Number:
Japanese Patent JP2023162111
Kind Code:
A
Abstract:
To improve the encoding efficiency for attribute information in point cloud information.SOLUTION: A point cloud encoding device includes: an interpolation unit that performs interpolation processing on a reconstructed point cloud of encoded frame regarding attribute information of point cloud information to generate a reference frame with decimal precision; a motion estimation unit that generates motion information by estimating motion between the decimal precision reference frame and the integer precision frame; a prediction unit that generates a predicted value on the basis of the motion information; and an entropy encoding unit that entropy encodes the difference between the point group of the frame and the predicted value.SELECTED DRAWING: Figure 8
