Method for all-angle automatic collection and generation of virtual data set

Abstract

The invention belongs to the technical field of data mining and discloses a method for all-angle automatic collection and generation of a virtual data set. A real object is subjected to high-precision modeling, and a real material of a model is simulated through a simulation algorithm; by performing simulation change on an environment in which the model is located, the object is subjected to all-angle quick extraction of a large amount of visual images from different angles, different scenes and different illumination environments; and during output, automatic classification is performed automatically according to an extracted target model and other environment information to form the data set. A virtual sample which can be used for high-dimensional data prediction can be generated more accurately; a large amount of data can be generated in a short time; the manpower and material resources for collecting the data set at present are greatly reduced; the model has high plasticity; and by simulation under different views, the data set is better in genericity and more reliable.

Description

technical field [0001] The invention belongs to the technical field of data mining, and in particular relates to a method for automatically collecting and generating a virtual data set from all angles and a graphical simulation system. Background technique [0002] Most of the existing datasets are collected from public image databases and video databases and manually marked. These public databases are mostly taken from the perspective of humans, so the collected datasets have great limitations in terms of angle and content. The process of simultaneous collection and labeling takes a lot of time and manpower. [0003] In summary, the problems in the prior art are: [0004] 1. There is no quick way to collect data sets, and the collection of data sets cannot be done manually. [0005] 2. Most of the existing data sets are limited in angle content, and it is impossible to observe and extract objects from all angles. Contents of the invention [0006] Aiming at the problem...
