Digital labeling method and device for three-dimensional object

Abstract

The invention relates to a digital labeling method and device for a three-dimensional object, belongs to the technical field of artificial intelligence, and solves the problems of high difficulty in knowledge labeling of the three-dimensional object and low labeling accuracy in the prior art. The method comprises the following steps: acquiring two-dimensional pictures, pose information and labeling labels of a three-dimensional object at different angles to form a training sample set; constructing an offset matrix and an enhanced angle rotation matrix of the sample based on the pose information in each sample; training the annotation network model by using the training sample set and the corresponding offset matrix and the enhanced angle rotation matrix to obtain an optimized annotation network model; and marking a to-be-marked three-dimensional object by using the optimized marking network model based on the two-dimensional picture and the pose information of the to-be-marked three-dimensional object. According to the method, the three-dimensional object labeling is converted into the two-dimensional labeling, the labeling difficulty is reduced, the association relationship between the labeling and the three-dimensional object is established through the artificial intelligence model, and the labeling accuracy of the three-dimensional object is improved.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to a method and device for digitally marking three-dimensional objects. Background technique [0002] In the existing technology, electronic components, printed food, aviation precision manufacturing, precision electronic parts, precision ceramic parts, product assembly link detection, product classification identification, product positioning detection, printed matter detection, bottle cap detection, glass, tobacco, art sculpture There are many physical models in various fields, and these physical models are all determined by the production process, lacking a consistent digital physical model. To obtain a digital physical model, the entity must be marked with knowledge. [0003] In the prior art, on the one hand, laser point cloud scanning is used for digital labeling; on the other hand, entity labeling is used, for example, a highlighter is used to mark on a three-...
