3D Machine Learning: One of the most researched topics that has received much attention in recent years.
The combination of machine learning, computer vision, and computer graphics is what completes a 3D machine learning model.
The term “3D machine learning” has become popular due to recent research in areas such as self-driving cars, augmented reality, virtual reality, and autonomous robots. The main goal of 3D machine learning is not to analyze just one model, but to analyze the entire ensemble of these models using maps or correspondence and computational alignment, etc.
For a better understanding, we’ll look at some 3D models.
3D Object Detection:
This is a contribution to the PASCAL3D + (2014) dataset, a challenging dataset for 3D object detection and gesture estimation.
These methods have gained popularity because they can easily control uncertainty even in 2D images to provide better descriptions of objects compared to 2D sensors.
Compared to existing 3D datasets, PASCAL3D + images provide better variability.
A total of 12 categories, each providing an average of 3K + objects for 3D object detection and gesture estimation.
Huge scanned dataset:
Created a dataset of over ten thousand 3D scans of real objects. About 70 operators with user-portable 3D scanning installations were asked to scan objects of their choice in their environment without any supervision from a computer vision professional. As a result, there is a large and diverse collection of objects – toys, plush pianos, shoes, mugs, vases, and construction vehicles, among others. This task is performed with the help of lawyers to ensure that data collection is not subject to any kind of privacy restrictions. This dataset, along with the reconstructed model and RGB-D scans, is publicly available for proper use.
A total of 10k RGBD scans and reconstructed 3D models were performed in .PLY format.
If you dig deeper, you’ll find several other pieces of information about 3D machine learning models, such as ABC: Big Data Sets of CAD Models for Deep Geometric Learning, ShapeNet, and Semantic3D, among others.
Well, creating such a model would not be possible without the support of Python libraries. Let’s talk more about the best Python libraries for 3D machine learning.
