Rebuild my 3D world [open source] [serialization-2]

Today, I took some photos of the blue sky and white clouds in the park , Choose one to share with you

Follow the previous one for reconstruction 3D After the world series started , Bloggers are not resting , On the one hand, in the communication with friends , There are many suggestions for me Colmap replace OpenMVG To complete SFM part , The reason is that Colmap Of SFM than OpenMVG More stable , This makes bloggers have other ideas on the scheme , It's actually a choice Colmap+OpenMVS still OpenMVG+OpenMVS, Practice leads to true knowledge , I will compile at the same time Colmap and OpenMVG, Test some data to observe the results before making a decision , I will open another blog to sort out the test results .

Have to say ,Colmap The compilation of is really very troublesome , Compared with OpenMVG It seems very easy , I'm not only trying to compile myself these days , Also looking for a friend orange [ Big orange's blog ] Want a version that he compiles . The process is not easy .

In other words , Take advantage of the neutral position of compilation , We can't be idle , Rookie QT The road of practice is still long and far away , This article brings you some efforts and progress in the interface .

1 The image can be controlled and previewed

As we mentioned earlier , stay UI Image loading and display are realized in , But this is only the first step , Some image interactions that must be followed , Including image pan and zoom , Are very basic functions . I overloaded the image view control , And rewrite the drawing function in the drawing event . For details, please refer to the source code QImgViewWidget Class implementation .

Besides , I also added the multi image preview function , In this way, you can have a preliminary browse of the entire image set , The preview image generation of the whole image set is relatively slow , So I rewrite an inheritance from QThread The preview of updates the thread class QUpdatePreviewThread To complete the generation of background preview .

2 The window can be adaptive

As QT rookie , Window adaptation was not done in the previous article , Mainly based on implementation modules , Now? , This part also adds , Operate the zoom of the whole main interface , The internal sub window will also change its size adaptively . Concrete , I overloaded in the main window resizeEvent Method , A size adaptation is made for all windows .

3 A little progress of the model display window

Model display window , Is based on OpenGL 3D display window , I'm also thinking about using existing mature rendering engines such as OSG, Or based on OpenGL A more primitive implementation of , Finally, I decided to use the latter for the time being , At the beginning, try to lighten it . The current development is to write an overload with QOpenGLWidget Window class of QModelViewGLWidget, And overloaded the basic rendering related methods, such as initializeGL、resizeGL、paintGL, But the specific implementation has not been completed .

4 Temporarily removed the right OpenCV and Eigen Dependence

The above said , At the beginning, I hope the whole project will remain light , At present, it is not used OpenCV and EIgen The place of , Maybe it will be added later , But for the time being, let's remove .

5 The source code has been updated

The above operation , I'm all in Github The warehouse is updated in real time , As you can pull Down to experience .

Project source code address ：TellusBuilder

Interested students , It is suggested to click star and watch, Of course, based on my work, what I want to do in the future is also welcome fork ah .**
