[PYTHON] [Introduction] How to use open3d

1.First of all

1-1. The opportunity to write an article

I decided to use open3d for work, but from the initial introduction to grasping the basic functions It took a long time, so I would like to summarize what I have grasped.

1-2. Target readers

・ People who have decided to use Open3D for work but do not know what to start with ・ People who want to handle Depth as well as RGB but do not know what to do first ・ In addition to the above, people who are not good at English

2. Related sites

The sites I read are as follows. https://blog.negativemind.com/2018/10/17/open3d/ http://robonchu.hatenablog.com/entry/2018/02/24/200635 https://qiita.com/n_chiba_/items/fc9605cde5c19a8c7dad


3-1. The most important thing.

Like other libraries and frameworks, the tutorials on the official website are the most detailed, correct and up-to-date. First, let's read the official website.

3-2. Official document

URL: http://www.open3d.org/docs/release/index.html

Read Get started for instructions. http://www.open3d.org/docs/release/getting_started.html

3-3. Operation check

4 Point Cloud notes

If the point cloud remains, the amount of data will be enormous. It is often converted to a 3d surface and used.

Because point data alone is difficult to use for analysis ・ Class and instance classification by segmentation ・ Setting the surface shape by making it a surface And so on.

5 Next action

・ If you paste the 3D data link into the following project, you can contribute to the 3D data community, so I would like to do it. https://github.com/awesomedata/awesome-public-datasets/tree/master
