Hello,
First of all sorry about my english, it's far from perfect.
I want to use the rtabmap program to extract a point cloud from a stereo video, in this case stereo video from 2 go pro camera.
I do not need to work in real time.

I have installed the stand alone rtab map program. With it, i have used the files from the stereovision tutorials and i was able to obtain a point cloud.

Now i am completely lost on how to use it with my videos.

I have 2 go pro camera and the stand alone rtab map program.

From what i understand, i need to
1) synchronize the 2 videos ==> done
2) calibrate the cameras ==> is the tool rtabmap calibrate can do it or do i have to use another way (opencv)? In case i extract the calibration data with another tool, how to use it?
3) use rtab map with the video ==> do i have to open the video one by one ? or do i have to mix the video in one file ?

Sorry about all these questions but i am really lost on how to use rtab map properly. The stereovision file from the tutorials worked correctly and it's frustrating to not be able to use my data.

Thanks for your help.
