Hi!, This is an Android project with the Structure from Motion process you can get from the Chapter 4 of the OpenCv Book. To this i first configure: a. Android Studio b. You have to install the NDK tool from the Android SDK Manager. All was done in a Windows 10 Machine, i won´t compile the PCL libraries. ------///--------- Some things ---------///--------- There is some problem in the pipeline, and the reconstructions are allways the same, that's a problem we have to solve :(. In the Android Manifest you will find diferent classes commented <!--- ----> i do this to test the diferent parts of the algoritm. The full code Will be comented in spanish if i'm able to translate that i will commit the changes, the main advantage of this project is the understanding of the variables and methods you have to use all in Java. Good Day!
