🤗4.1 Cluster Computing

Start tutorial about cluster computing

Note：

(1) Before performing cluster computing on multiple computers, please make sure that each computer is connected to same LAN and can connect each other. Each machine has read and write permission to other computers.

(2) Get3D Mapper software contains two modules: Get3D Mapper (UI for user to operate) and Get3D Engine runs at background (algorithms for automatic modeling).

1 Download & Installation

First, download and install Get3D Mapper on each computer.

The Get3D Mapper installation process will automatically accompany the installation of Get3D Engine.

After finishing the installation,

(1) Open the Get3D Mapper software on each of the 10 computers,

(2) Log in to your account and activate the licence to each computer.

The tutorial of how to obtain license：

3 Start Engine

Click Setting>Engine Directory Setting in the menu bar.

Then click Start Engine to access the Get3D Engine interface.

Start the engine on all computers:

4 Create Project

After obtaining license and starting the engine on all 10 computers.

Select a computer as the master computer and create project.

Please set the project path to a network path that can be accessed by other computers. Subsequent operations can be completed on the project of this master computer.

Note:

All operations except Collaborative Mark Ground Control Points can be performed only on the main project of the master computer:

Creation of the project；
Import of the images；
Positioning of the images；
Submission of the Relative Orientation；
Submission of the Absolute Orientation；
Submission of Reconstruction (generation of the 3D mesh model).

Similarly, mobilizing the computational power of each engine node, managing the start or pause of the engine nodes, etc., can be done from a single engine interface.

The tutorial of how to create project：

5 Set Engine Directory

After creating the project, set the engine directory. Set both the Task Directory and the Monitor Directory to the same network path.

Note：

There are four paths in the cluster calculation that need to be network paths:

① 【Create & Open Project】 Project Path

② 【Engine Settings】 Task Directory Path (② and ③ are consistent)

③ 【Engine Settings】 Monitor Directory Path (② and ③ are consistent)

④ 【Import & Read Image】 Image Path

The tutorial of how to setting engine path：

6 Import Image & Positioning

The tutorial of how to import images and positioning:

7 Submit Task & Distribute Engine Nodes

Task submission:

After completing the image import and positioning, and correctly filling in the Camera Information (Sensor Size and Focal Length), click Submit AT.

Distribute Engine Nodes:

(1) Open the engine interface. In the Engine Information column, you can see the current state of the Engine (Waiting, Running, Stop), the version of the Engine, and the address of the Task Path and so on.

(2) Select all Engines, right click and select Modify Monitor Directory. Setting the path of all the 10 Engines to the task path set when the main project submits the task.
