SfM | lightweight SLAM for 3D scanning | Computer Vision library

I'm trying to use ActionChains to click a button with python but it just refuses to work no matter what I do.

The issue is that whenever the website opens, it opens with an overlay. I want my program to click the 'OK' button on the overlay. Whatever code I write just ends up clicking the overlay itself.

Here is my code:

I try to build the OpenCV 4.5.1 SDK for Android because I need the SDK with contrib modules and the official release [1] only has the standard modules. But the libraries I build are almost 10x larger, for example: libopencv_core.a ==> 47.6 MB self compiled, 5.3 MB from the official repository (both for arm64-v8a)

Here is my cmake command, followed by ninja for compilation.

I have trouble finding a good example on how to swipe between fragments with help of bottom navigatiom bar. Since FragmentStatePagerAdapter is deprecated and a new ViewPager2 is now recommended instead of the old ViewPager I want to use ViewPager2 and FragmentStateAdapter in my code instead. I have found an example of how to combine BottomNavigationBar and ViewPager here and I want to do something similar. My code have many similarities to the one in the example with the only difference that I have my code in a fragment instead of an activity. Here is a picture of how my FrontendFragment display look like. I can switch between the views using the bottomnavigationbar but I also want to be able to swipe between the views. Can someone help me or at least direct me on the right way? Here is my code:

I am trying to install SFML(2.5.1) in CODEBLOCK(20.03) with and currently using windows 8.1. I have downloaded sfml-tdm-sjlj-32 bit as per the tutorials that I saw in the web. I did all the set-ups and declared all the linkers properly but unfortunately it gave me error asking for libgcc_s_sjlj-1.dll not found so I downloaded it and added to my CODEBLOCK environment. After doing so I build and debugged a code that I got from SFML::CODEBLOCK tutorial just to test it but it gives me the following error -

The procedure entry point_gxx_personality_sj0 could not be located in the dynamic link library c:\sfm\sfml\sfm-graphics-d-2.dll

thank you in advance :)

I am new in the field of CV and trying to Triangulate Points between three Pictures but for the beginning, I want to Triangulate between two Pictures. For that, I made these Steps:

1. Feature detection with AKAZE
2. Feature matching by NORM_HAMMING
3. Filter the Matches
4. Match the filtered descriptors with the KeyPoint Coordinates

After that, I have a Vector of KeyPoints for each Image of the same size. Know i want to convert this Vector to "cv::Mat", so that i can use the TriangulatPoints function:

I am trying to compile OpenCV for Android with contrib modules, mainly I am interested in sfm. I did a lot of research and finaly I did the following in order to support sfm:

Compiled gflags Compiled Glog Compiled Ceres

After that I used this cmake command to build and generate (partial output is given below):

I am not able to compile the sfm module for opencv using cmake.

The following log shows that cmake finds both glog and gflags, but compilation fails.

Can someone help me with the Python code to read the .mat file generated from Visual SFM? You can download the .mat file from the link:

https://github.com/cvlab-epfl/tf-lift/tree/master/example

You can get a .mat file in the zip in the link and the file is what I am asking for help. It seems to be an ASCII file. I do not know how to read the data in the file. I tried to load the data in the .mat file with scipy.io.loadmat() but an error occurred as:
