I try to build a slam robot with kinect. I cant get any reliable data from my encoders so i want to generate odometry data via kinect. When i look for it topics are outdated so is there anyway to generate odometry data for slam via kinect?

It’s possible, it’s called visual odometry or visual slam. There is a video that shows how to: https://youtu.be/c5punaP01kU

It’s not the most reliable either and it will depend on the hardware you are using. The video uses a RPI 4 so it’s in the low end of the spectrum.

You can use the kinect in two ways, Frist less computational. You extrackt a scan line from your kinect pcl stream and use it as the imput for a classical slam See here: wiki

Or you use the full pcl an starts with 3d slam also known as Rgb D slam. see here: youtube Or read here : wiki
