Recently, the instructor asked to investigate the point cloud annotation tool, learned about Semantic Segmentation Editor, and recorded the installation process
This is an online installation tool. Developed in the context of autonomous driving, it supports semantic segmentation and annotation of 2D image data (.jpg and .png) and 3D data (.pcd).
installation steps:
(1) Install Node.js
Node.js is a JavaScript runtime environment based on Chrome's V8 JavaScript engine. It provides a way to enable JavaScript code to run on the server side, through Node.js you can use JavaScript to write server-side applications and network applications

(2) Install Chocolatey
Chocolatey is a Windows package manager tool that can quickly install, upgrade, and delete software on Windows through the command line or a graphical interface. It allows users to easily search, download and install thousands of software, saving users the tedious work of finding a separate installation package for each application and installing it manually. Chocolatey is built on PowerShell, which provides a simple and powerful software management method, which can quickly install and update the required software packages in Windows systems just like using package managers in Linux systems.
*Open the command prompt cmd as an administrator (search for cmd on the computer, right-click to run as an administrator) (do not open cmd directly)
*enter:
@"%SystemRoot%\System32\WindowsPowerShell\v1.0\powershell.exe" -NoProfile -InputFormat None -ExecutionPolicy Bypass -Command " [System.Net.ServicePointManager]::SecurityProtocol = 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))" && SET "PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin"It takes about 20 minutes to install
*After the installation is complete, enter
choco -versioncheck version
(3) Install Meteor
Meteor is a JavaScript full-stack framework for rapidly developing and building modern web and mobile applications
* run cmd as administrator
*enter:
choco install meteorIt takes about 10 minutes
When a line appears: Meteor has been installed! It means the installation is successful
* Set meteor environment variables
Windows Select Control Panel - System and Security - System - Advanced System Settings - Advanced - Lower Right Corner (Environment Variables) - System Variables (Below) - Slide the mouse to find (Path) - New - Enter C :\Users\your username\AppData\Local\.meteor——click OK
* check version
meteor --version4) Download semantic-segmentation-editor-master and extract it to the current folder
URL: https://github.com/Hitachi-Automotive-And-Industry-Lab/semantic-segmentation-editor
*Installation: Run cmd as an administrator, cd to the semantic-segmentation-editor-master path, and run:
Meteor npm installWhen you see a picture similar to the following, the installation is complete:
*Run: Command line continue to enter:
meteor npm startThe whole process takes a long time and has a lagging phenomenon, please try multiple times (or press Esc multiple times to try)
(I have also installed it many times. When an error occurs, restart the administrator to open cmd and re-enter the command. Press Esc when it freezes, and stop pressing it when the command line starts to change.)
When the above picture appears, it means that some missing packages are being initialized and installed, which means that they are being installed, please wait patiently. When the following figure appears, it means that the installation is successful, and thehttp://localhost:3000/
Copy to the browser to open the software (if the URL cannot be opened, please try more browsers)
The URL opens to show:
That means the installation is successful!
(5) Open your own point cloud file (.pcd)
Put the data that needs to be labeled into: C:\Users\yourName\sse-images
Refresh http://localhost:3000/ again to see the point cloud data
Double click to open the file
But at present, when I open my .pcd file, a black screen is displayed, and I have not found a suitable solution. Friends who have solved it are welcome to share their experience cases in the comment area.
This is the official .pcd data, which can be changed according to your own format
