Title:
NEURAL RADIATION FIELD-BASED METHOD AND APPARATUS FOR CONSTRUCTING PEDESTRIAN RE-IDENTIFICATION THREE-DIMENSIONAL DATA SET
Document Type and Number:
WIPO Patent Application WO/2023/093186
Kind Code:
A1
Abstract:
Disclosed in the present invention are a neural radiation field-based method and apparatus for constructing a pedestrian re-identification three-dimensional data set. The method comprises the following steps: S1, by means of a group of cameras having different visual angles, carrying out image acquisition on pedestrians to be input; S2, by means of camera rays in the scene, sampling and generating a three-dimensional space position point set, and converting observation directions of the cameras corresponding to the three-dimensional space position point set into three-dimensional Cartesian unit vectors; S3, inputting the three-dimensional space position point set and the observation directions of the three-dimensional Cartesian unit vectors converted from the three-dimensional space position point set into a multi-layer perceptron, and outputting the corresponding density and color. By means of the neural radiation field-based method and apparatus for constructing a pedestrian re-identification three-dimensional data set in the present invention, a brand-new method for constructing a pedestrian re-identification data set is provided, and a new idea for constructing a data set is provided. Compared with traditional methods for constructing a data set, the present solution uses images and the spatial positions collected by multiple apparatuses, such that the data acquisition mode is more direct and clear.
