How to export properties such as Box center and Box dimensions

[Ph.Wo.]

Hey,

i need the same feature, but my knowlege about c++ is realy bad. So if anybody has something that will work, or maybe have a nother solution to geht the bounding box for a lot Pointclouds, please let me know.

Have a nice day,

Philipp

Well, the code modifications are really easy.

In the current version, after the line 8454 of mainwindow.cpp (csvStream << "meanZ;";) you can add:

Code: Select all

csvStream << "minX;";
csvStream << "minY;";
csvStream << "minZ;";
csvStream << "maxX;";
csvStream << "maxY;";
csvStream << "maxZ;";

And after the line 8479 of mainwindow.cpp (csvStream << G.z << ";";) you can add:

Code: Select all

csvStream << cloud->getBB_recursive().minCorner().x << ";";
csvStream << cloud->getBB_recursive().minCorner().y << ";";
csvStream << cloud->getBB_recursive().minCorner().z << ";";
csvStream << cloud->getBB_recursive().maxCorner().x << ";";
csvStream << cloud->getBB_recursive().maxCorner().y << ";";
csvStream << cloud->getBB_recursive().maxCorner().z << ";";

I changed code according to the instructions above, and tried the command below to install the CC.

1. mkdir build & cd build
2. cmake -DCMAKE_PREFIX_PATH=C:\Qt\5.15.2\msvc2019_64 ..
3. cmake --build . --config Release
4. cmake --install .

Then, I got the error shown below during the building step 3.

I guess it's an issue with the version of Qt you are using as 'setStepType' has been introduced in version 5.12.

Providing the path to Qt as 'CMAKE_PREFIX_PATH' may not be sufficient to force Qt to use this particular version. You should use the GUI version of CMake and check which version is actually found by CMake.

Thank you, Daniel. I was able to compile it successfully following the tutorial in one YouTube video, which uses GUI CMAKE rather than the command line of CMAKE.

Yes, it basically consists in 'hacking' the code of the 'Tools > Batch export > Export cloud info' method.

You can find it in the big 'mainwindow.cpp' file, and the method is called MainWindow::doActionExportCloudInfo.

The current versions saves various pieces of info, but you should be able to comment a lot of lines. And to get the bounding-box extents, just call the 'getBoundingBox' method of each 'cloud' instance.

Hi Daniel, has there been any updates to this solution? I have not found any files with those names. If you could please help me out with this?
